Background: Early childhood educators play a critical role in promoting physical activity and reducing sedentary time in childcare centres. However, early childhood educators receive limited specialised pre- and in-service learning opportunities relating to these behaviours and may lack the capacity to effectively engage children in healthy movement behaviours. This study aimed to examine the efficacy of an e-Learning course on increasing early childhood educators' physical activity and sedentary behaviour-related capacities., Methods: A two-group parallel randomized controlled trial was conducted with early childhood educators in Canada (M age = 41.78, 97% female). Participants randomized to the intervention group were asked to complete a physical activity and sedentary behaviour e-Learning course within a 4-week period. Participants randomized to the waitlist control condition were assigned to a waitlist to receive the intervention after the testing period. Participants reported on their self-efficacy, knowledge, intentions, and perceived behavioural control relating to physical activity and sedentary behaviours at baseline, post-intervention, and 3 months follow-up. Linear mixed effects models were estimated to determine difference in changes in outcomes from baseline to post-intervention, and follow-up., Results: A total of 209 early childhood educators participated in the study (intervention n = 98; control n = 111). The TEACH e-Learning course was found to be efficacious at improving all of the examined outcomes, with standardized effect sizes ranging from d = 0.58 to d = 0.65 for self-efficacy outcomes, d = 0.66 to d = 1.20 for knowledge outcomes, d = 0.50 to d = 0.65 for intention outcomes, and d = 0.33 to d = 0.69 for perceived behavioural control outcomes post-intervention. The intervention effects were sustained at follow-up for all outcomes apart from perceived behavioural control to limit screen time. Additionally, the magnitude of the effect for knowledge outcomes decreased at follow-up, with standardized effect sizes ranging from d = 0.49 to d = 0.67., Conclusions: The e-Learning course was highly successful at improving early childhood educators' capacity pertaining to physical activity and sedentary behaviours. Providing training content through e-Learning may be an efficacious approach to providing continual professional learning opportunities relating to physical activity and sedentary time to early childhood educators on a large scale., (© 2024.

Purpose: We aimed to study the effect of music therapy combined with aerobic exercise on the sleep quality of patients undergoing chemotherapy after a radical mastectomy., Methods: A randomized controlled trial was conducted at the Breast Disease Diagnosis and Treatment Center, Shaanxi Province Tumor Hospital, from July 2017 to June 2019. 110 female breast cancer patients who underwent a radical mastectomy were recruited and randomly allocated into an intervention group or a control group. The intervention group completed music therapy combined with aerobic exercise from the first to the sixth admission to the hospital for chemotherapy, while the control group received only routine nursing care. The sleep quality of these patients was measured using the Pittsburgh Sleep Quality Index (PSQI). A linear mixed model was used to adjust the PSQI of patients after controlling for other confounding factors., Results: The mean sleep quality score of the breast cancer patients who received chemotherapy after a radical mastectomy (baseline) was 8.86 ± 2.34. The intervention group had a significantly lower mean global PSQI score than the control group from the first test to the third test, with an adjusted mean difference of -1.05 (95%CI: -1.86, -0.24; P = 0.01), -2.89 (95%CI: -3.70, -2.08; P < 0.001) and - 4.84 (95%CI: -5.65, -4.03; P < 0.001), respectively. A change in the global PSQI score from baseline for the intervention group was from 0.55 (95%CI: -0.24, 1.34; P = 0.171) at the first test to 2.75 (95%CI: 1.96, 3.53; P < 0.001) at the last test, and for the control group was from - 0.51 (95%CI: -1.31, 0.29; P = 0.213 at the first test to -2.10 (95%CI: -2.91, -1.30; P < 0.001) at the last test., Conclusions: An intervention of music therapy combined with aerobic exercise can significantly improve the sleep quality of female breast cancer patients undergoing chemotherapy after a radical mastectomy, and this intervention continuously improves many aspects of sleep reactivity., Clinical Trial Registration: This study was registered in the Chinese Clinical Trial Registry (ChiCTR2100042975, 02/02/2021)., (© 2024.

Study Objectives: A 2021 survey by the World Health Organization showed that 27% of the global population experiences sleep problems and that middle-aged and older adults are more likely to have sleep disorders. Sleep deprivation increases cardiovascular disease risk. This study aimed to assess the effects of aerobic exercise, resistance exercise, combined training, and yoga on the quality of sleep in middle-aged and older adults through their effects on the Pittsburgh Sleep Quality Index (PSQI) and its components. Direct and indirect comparisons were used to determine which exercise modality most effectively improves sleep quality in middle-aged and older adults., Methods: This study conducted a systematic review and frequency network meta-analysis of all randomized controlled trials comparing the effects of aerobic exercise, resistance exercise, combined training, and yoga with a control group on sleep quality in middle-aged and older adults., Results: We included 28 studies involving 3,460 participants. According to the surface under the cumulative ranking (SUCRA) curve results, aerobic exercise was the most effective in improving total PSQI score (SUCRA = 93.2%), sleep latency (SUCRA = 96.8%), and sleep medication use (SUCRA = 77.1%). In addition, yoga was the most effective in improving sleep disorders (SUCRA = 90.4%), sleep efficiency (SUCRA = 95.9%), sleep duration (SUCRA = 93.8%), and daytime dysfunction (SUCRA = 98.3%)., Conclusions: Aerobic exercise is the most effective exercise modality for improving PSQI total score in middle-aged and older adults., Systematic Review Registration: Registry: PROSPERO; Identifier: CRD42023454237., Citation: Gao X, Qiao Y, Chen Q, Wang C, Zhang P.

Background: The lack of regular physical activity (PA) in individuals with spinal cord injury (SCI) in the United States is an ongoing health crisis. Regular PA and exercise-based interventions have been linked with improved outcomes and healthier lifestyles among those with SCI. Providing people with an accurate estimate of their everyday PA level can promote PA. Furthermore, PA tracking can be combined with mobile health technology such as smartphones and smartwatches to provide a just-in-time adaptive intervention (JITAI) for individuals with SCI as they go about everyday life. A JITAI can prompt an individual to set a PA goal or provide feedback about their PA levels., Objective: The primary aim of this study is to investigate whether minutes of moderate-intensity PA among individuals with SCI can be increased by integrating a JITAI with a web-based PA intervention (WI) program. The WI program is a 14-week web-based PA program widely recommended for individuals with disabilities. A secondary aim is to investigate the benefit of a JITAI on proximal PA, defined as minutes of moderate-intensity PA within 120 minutes of a PA feedback prompt., Methods: Individuals with SCI (N=196) will be randomized to a WI arm or a WI+JITAI arm. Within the WI+JITAI arm, a microrandomized trial will be used to randomize participants several times a day to different tailored feedback and PA recommendations. Participants will take part in the 24-week study from their home environment in the community. The study has three phases: (1) baseline, (2) WI program with or without JITAI, and (3) PA sustainability. Participants will provide survey-based information at the initial meeting and at the end of weeks 2, 8, 16, and 24. Participants will be asked to wear a smartwatch every day for ≥12 hours for the duration of the study., Results: Recruitment and enrollment began in May 2023. Data analysis is expected to be completed within 6 months of finishing participant data collection., Conclusions: The JITAI has the potential to achieve long-term PA performance by delivering tailored, just-in-time feedback based on the person's actual PA behavior rather than a generic PA recommendation. New insights from this study may guide intervention designers to develop engaging PA interventions for individuals with disability., Trial Registration: ClinicalTrials.gov NCT05317832; https://clinicaltrials.gov/study/NCT05317832., International Registered Report Identifier (irrid): DERR1-10.2196/57699., (©Rachel L Carey, Ha Le, Donna L Coffman, Inbal Nahum-Shani, Mohanraj Thirumalai, Cole Hagen, Laura A Baehr, Mary Schmidt-Read, Marlyn S R Lamboy, Stephanie A Kolakowsky-Hayner, Ralph J Marino, Stephen S Intille, Shivayogi V Hiremath.

Background: Active surveillance (AS) is increasingly used to monitor patients with lower risk prostate cancer (PCa). The Prostate Cancer Active Lifestyle Study (PALS) was a randomized controlled trial to determine whether weight loss improves obesity biomarkers on the causal pathway to progression in patients with PCa on AS., Methods: Overweight/obese men (body mass index >25 kg/m 2 ) diagnosed with PCa who elected AS were recruited. The intervention was a 6-month, individually delivered, structured diet and exercise program adapted from the Diabetes Prevention Program with a 7% weight loss goal from baseline. Control participants attended one session reviewing the US Dietary and Physical Activity Guidelines. The primary outcome was change in glucose regulation from baseline to the end of the 6-month intervention, which was measured by fasting plasma glucose, C-peptide, insulin, insulin-like growth factor 1, insulin-like growth factor binding protein-3, adiponectin, and homeostatic model assessment for insulin resistance., Results: Among 117 men who were randomized, 100 completed the trial. The mean percentage weight loss was 7.1% and 1.8% in the intervention and control arms, respectively (adjusted between-group mean difference, -6.0 kg; 95% confidence interval, -8.0, -4.0). Mean percentage changes from baseline for insulin, C-peptide, and homeostatic model assessment for insulin resistance in the intervention arm were -23%, -16%, and -25%, respectively, compared with +6.9%, +7.5%, and +6.4%, respectively, in the control arm (all p for intervention effects ≤ .003). No significant between-arm differences were detected for the other biomarkers., Conclusions: Overweight/obese men with PCa undergoing AS who participated in a lifestyle-based weight loss intervention successfully met weight loss goals with this reproducible lifestyle intervention and experienced improvements in glucose-regulation biomarkers associated with PCa progression., (© 2024 American Cancer Society.)

Background: Little is known about the impact of an ecological dynamics (ED) intervention (EDI) on primary school children's physical literacy and well-being in the Hong Kong context. The aim of this project is to introduce a physical literacy and well-being framework through an EDI that allows primary school children to develop good physical activity (PA) and daily behavioural habits., Methods and Analysis: A four-arm (cluster) randomised controlled trial will be conducted to examine the effect of EDI on physical literacy and well-being in primary schools located in each of the 18 administrative districts of Hong Kong. Four classes in senior primary students (grade 4) at each school will be randomly assigned to the four different conditions. These participating schools will be equipped with sit-stand desks, PA recess facility and equipment, and sleep pillows. The research team will adopt both objective measures (aerobic fitness, fundamental movement skills, daily behaviour-physical activity and cognitive function) and self-reported measures (perceived physical literacy, quality of life, sleep quality) covering the elements and domains of physical literacy and well-being to examine the effects of EDIs at four time points, including baseline assessment, 3 months after intervention, postintervention and 3-month follow-up assessment. One-way analyses of variance (ANOVAs) will be used to test for differences in the baseline characteristics of participants between groups. Repeated measure ANOVAs and MANCOVA, with time (baseline, after intervention and follow-up) as within-subjects factor, and intervention group as between-subjects factors, will be used to evaluate the effects of different interventions on the students' physical literacy and well-being. A Bonferonni correction to the p value will be calculated to adjust for multiple tests., Ethics and Dissemination: Ethical approval was sought from the Joint CUHK-NTEC Clinical Research Ethics Committee in Hong Kong (CREC Ref.No.:2024.027). The finding of this study will be disseminated via peer-reviewed journals, international conference presentations and academic lectures.

Background: Midlife hypertension is associated with cognitive decline and Alzheimer's disease and related dementia (ADRD), suggesting that blood pressure control may be a therapeutic target for dementia prevention. Given excess hypertension in non-Hispanic Black (NHB) adults, blood pressure control may also reduce ADRD disparities. We describe a pilot randomized controlled trial (RCT) to evaluate the feasibility and preliminary efficacy of a multicomponent lifestyle-based intervention versus enhanced usual care on cognition among middle-aged NHB adults., Methods and Study Design: The Food Resources and Kitchen Skills plus Aerobic Training (FoRKS+) study is a 2-arm, single-blinded trial that compares those receiving the FoRKS+ program (target N = 64) versus those receiving enhanced usual care (target N = 64) in local federally-qualified health centers. Key eligibility criteria include self-identified NHB adults between ages 35-75 with a mean systolic blood pressure ≥ 130 mm/Hg obtained from 24-h ambulatory blood pressure monitoring. The FoRKS+ program includes 5 weeks of hypertension self-management courses, 11 weeks of nutrition courses, and 12 weeks of aerobic training in dietitian and health coach-led virtual groups. We will collect data on primary cognitive outcomes, feasibility, hypothesized intervention mediators and moderators, and demographic and health covariates at baseline, near intervention weeks 16-, and 28 (primary outcome assessment), and week 52 follow-up. We will use mixed-effects modeling to examine intervention effects on cognition., Discussion: This pilot RCT will examine the feasibility and preliminary effects of a multicomponent lifestyle intervention on cognitive function in NHB adults, which may have implications for reducing health disparities in ADRD., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: Childhood cancer survivors (CCS) are at risk of experiencing lower quality-of-life, fatigue, and depression. Few randomized controlled trials have studied the effect of physical activity (PA) on these in adult long-term CCS. This study investigated the effect of a 1-year individualized PA intervention on health-related quality-of-life (HRQOL), fatigue, and distress symptoms in adult CCS., Methods: The SURfit trial randomized 151 CCS ≥16 years old, <16 at diagnosis and ≥5 years since diagnosis, identified through the Swiss Childhood Cancer Registry. Intervention participants received personalized PA counselling to increase intense PA by ≥2.5 h/week for 1 year. Controls maintained usual PA levels. The authors assessed physical- and mental-HRQOL, fatigue, and distress symptoms at baseline, 3, 6, and 12 months. T-scores were calculated using representative normative populations (mean = 50, standard deviation = 10). Generalized linear mixed-effects models with intention-to-treat (ITT, primary), and three per-protocol allocations were used., Results: At 12 months, ITT (-3.56 larger decrease, 95% confidence interval -5.69 to -1.43, p = .001) and two per-protocol analyses found significantly lower fatigue. Physical-HRQOL improved significantly in two per-protocol analyses at 12 months. No other effects were found., Conclusion: SURfit showed that increased intense PA over 1 year improved fatigue in adult CCS. Survivors should be recommended PA to reduce the burden of late-effects., (© 2024 The Authors. Cancer published by Wiley Periodicals LLC on behalf of American Cancer Society.)

Aim: To describe the protocol of a feasibility trial designed to test the preliminary effect of a 12-week culturally appropriate physical activity programme on metabolic syndrome markers and quality of life in Ghanaian adults with type 2 diabetes (T2DM)., Design: Feasibility randomised controlled trial., Methods: Through random allocation, 90 adults with T2DM will be allocated to either the control group (CG) (n = 45) or the intervention group (IG) (n = 45). The IG will receive the physical activity programme in addition to their usual diabetes care; those in the CG will receive their usual diabetes care. Measurements will be performed at baseline and 12-week follow-up. The primary outcome is a change in metabolic syndrome markers in the IG compared to the CG. Secondary outcomes are: (a) a change in quality of life in the IG compared to the CG, (b) the feasibility of implementation., Results: Findings will inform the design of a future large-scale trial., Patient or Public Contribution: Patients with T2DM and their healthcare professionals contributed to this study protocol by participating in semi-structured interviews towards the design of the physical activity programme., Clinical Trial Registration Number: The trial is registered in the Australian and New Zealand Clinical Trial Registry (registration number: ACTRN12622000323729p)., (© 2024 The Author(s).

Introduction: Physical inactivity is a risk factor for obesity and non-communicable diseases. Despite myriad health and non-health benefits resulting from physical activity (PA), most individuals do not meet PA recommendations. Providing an incentive for meeting activity goals may increase activity levels. Classical economists argue that cash is the best incentive. Behavioral economists have posited that hedonic (pleasurable) incentives (e.g., massages, restaurant meals) may be superior to cash when incentives are offered over multiple time periods. To date, no studies have directly compared the effectiveness of cash versus hedonic incentives in promoting PA across multiple time periods., Methods: We conducted a two-arm, parallel, 4-month randomized controlled trial with healthy adults in Singapore where participants were randomized to either cash or hedonic incentives. Participants could earn up to SGD50 (≈USD37) in cash or hedonic incentives each month they met the study's step target of 10,000 steps daily on at least 20/25 days out of the first 28 days of a month. The primary objective was to compare the mean proportion of months that participants met the step target between the two arms., Results: By month 4, participants in the cash ( N  = 154) and hedonic incentive ( N  = 156) arms increased their mean daily steps by 870 ( p  < 0.001) and 1,000 steps ( p  < 0.001), respectively. The mean proportion of months the step target was achieved was 90.53 and 88.34 for participants in the cash and hedonic incentive arms respectively, but differences across arms were small and not statistically significant for this or any outcome assessed., Conclusion: Our findings suggest that both cash and hedonic incentives are effective at promoting physical activity but that neither strategy is clearly superior.

Background: Numerous smartphone apps are targeting physical activity (PA) and healthy eating (HE), but empirical evidence on their effectiveness for the initialization and maintenance of behavior change, especially in children and adolescents, is still limited. Social settings influence individual behavior; therefore, core settings such as the family need to be considered when designing mobile health (mHealth) apps., Objective: The purpose of this study was to evaluate the effectiveness of a theory- and evidence-based mHealth intervention (called SMARTFAMILY [SF]) targeting PA and HE in a collective family-based setting., Methods: A smartphone app based on behavior change theories and techniques was developed, implemented, and evaluated with a cluster randomized controlled trial in a collective family setting. Baseline (t 0 ) and postintervention (t 1 ) measurements included PA (self-reported and accelerometry) and HE measurements (self-reported fruit and vegetable intake) as primary outcomes. Secondary outcomes (self-reported) were intrinsic motivation, behavior-specific self-efficacy, and the family health climate. Between t 0 and t 1 , families of the intervention group (IG) used the SF app individually and collaboratively for 3 consecutive weeks, whereas families in the control group (CG) received no treatment. Four weeks following t 1 , a follow-up assessment (t 2 ) was completed by participants, consisting of all questionnaire items to assess the stability of the intervention effects. Multilevel analyses were implemented in R (R Foundation for Statistical Computing) to acknowledge the hierarchical structure of persons (level 1) clustered in families (level 2)., Results: Overall, 48 families (CG: n=22, 46%, with 68 participants and IG: n=26, 54%, with 88 participants) were recruited for the study. Two families (CG: n=1, 2%, with 4 participants and IG: n=1, 2%, with 4 participants) chose to drop out of the study owing to personal reasons before t 0 . Overall, no evidence for meaningful and statistically significant increases in PA and HE levels of the intervention were observed in our physically active study participants (all P>.30)., Conclusions: Despite incorporating behavior change techniques rooted in family life and psychological theories, the SF intervention did not yield significant increases in PA and HE levels among the participants. The results of the study were mainly limited by the physically active participants and the large age range of children and adolescents. Enhancing intervention effectiveness may involve incorporating health literacy, just-in-time adaptive interventions, and more advanced features in future app development. Further research is needed to better understand intervention engagement and tailor mHealth interventions to individuals for enhanced effectiveness in primary prevention efforts., Trial Registration: German Clinical Trials Register DRKS00010415; https://drks.de/search/en/trial/DRKS00010415., International Registered Report Identifier (irrid): RR2-10.2196/20534., (©Kathrin Wunsch, Janis Fiedler, Sebastian Hubenschmid, Harald Reiterer, Britta Renner, Alexander Woll.

Purpose: This study aimed to investigate the effects of a self-monitoring intervention to promote an increase in physical activity, as measured by step count, and reduce sedentary behavior in older people covered by the long-term care insurance system (LTCI) in Japan., Methods: This was a randomized controlled trial conducted at a daycare center from October 2022 to January 2023. Fifty-two older adults with LTCI who were able to walk with or without aids were assigned to an intervention (n = 26) group and control (n = 26) group. During the 5-week follow-up period, the intervention group received education on physical activity and self-monitoring such as goal setting, self-management and feedback. The primary outcome was step count, and the secondary outcome was sedentary behavior., Results: Participants who completed the study to the end of the 5-week follow-up and drop-out participants for whom outcome data were available were included in the final analysis of 57 participants, n = 24 (79.8 ± 8.8 years, male 25.5%) in the intervention group and n = 23 (82.5 ± 8.5 years, male 39.1%) in the control group. Comparisons between the two groups at baseline showed no significant differences. In the results of a two-way mixed analysis of variance (ANOVA) including 2 (group: control, intervention) × 2 (term: baseline, 5-week follow-up) factors, an interaction was observed in the number of steps, sedentary behavior, and light physical activity (p < 0.05)., Conclusion: Self-monitoring of physical activity using an accelerometer may be effective in increasing the number of steps and light physical activity and in reducing sedentary behavior in older people with LTCI., Clinical Trial Registration: UMIN000052044, registered on 2023/08/29., (© 2024.

Background and Objective: To revise and critically summarize the available scientific evidence regarding the effect of exercise on sleep quality in patients with chronic kidney disease (CKD)., Methods: A systematic review of randomized controlled trials (RCTs) and comparative studies was conducted, searching MEDLINE/PubMed, SPORTDiscus, and Scopus using keywords "Exercise", "Physical Activity", "Chronic Kidney Disease," and "Sleep". The methodological quality of included studies was assessed using the PEDRo and MINORS scales., Results: A total of 8 RCTs and 3 comparative studies were included, showing a low (n = 1), fair (n = 7), and good (n = 3) methodological quality. Most of the studies included patients undergoing hemodialysis (HD) (n = 8). Self-reported sleep quality (n = 9), sleepiness (n = 2), and objective sleep status (n = 2) were the main outcomes analyzed. The most frequent exercise interventions included aerobic training (n = 7), resistance training (n = 2), or a combination of both (n = 4). Generally, exercise induced positive effects on the reported outcomes. Data synthesis indicated that participants who exercised obtained significant improvements on their self-reported sleep quality in comparison with those included in the control groups, with a mean difference in the Pittsburgh Sleep Quality Index of - 5.27 points (95% CI - 7.76, - 2.77; p < 0.001)., Conclusion: Preliminary scientific evidence indicates that patients with CKD, especially those undergoing HD, report improvements in self-reported sleep quality after taking part in aerobic exercise programs, while combined training interventions yielded diverse findings. The effects of exercise on sleepiness and objective sleep status were backed by few studies with mixed results., (© 2023. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

We aimed to evaluate the dose-dependent effects of aerobic exercise on systolic (SBP) and diastolic blood pressure (DBP) and haemodynamic factors in adults with hypertension. PubMed, Scopus, and Web of Science were searched to April 2022 for randomized trials of aerobic exercise in adults with hypertension. We conducted a random-effects meta-analysis to estimate mean differences (MDs) and 95%CIs for each 30 min/week increase in aerobic exercise. The certainty of evidence was rated using the GRADE approach. The analysis of 34 trials with 1787 participants indicated that each 30 min/week aerobic exercise reduced SBP by 1.78 mmHg (95%CI: -2.22 to -1.33; n = 34, GRADE=low), DBP by 1.23 mmHg (95%CI: -1.53 to -0.93; n = 34, GRADE=moderate), resting heart rate (MD = -1.08 bpm, 95%CI: -1.46 to -0.71; n = 23, GRADE=low), and mean arterial pressure (MD = -1.37 mmHg, 95%CI: -1.80 to -0.93; n = 9, GRADE = low). A nonlinear dose-dependent decrement was seen on SBP and DBP, with the greatest decrement at 150 min/week (MD 150 min/week  = -7.23 mmHg, 95%CI: -9.08 to -5.39 for SBP and -5.58 mmHg, 95%CI: -6.90 to -4.27 for DBP). Aerobic exercise can lead to a large and clinically important reduction in blood pressure in a dose-dependent manner, with the greatest reduction at 150 min/week.

The global rise in the aging driving population has heightened concerns about traffic incidents involving this demographic. Beyond transportation, automobiles represent a vital lifeline for older adults, fostering social activities and influencing their health-related quality of life. This study explores improving and sustaining driving ability among older adults with anticipated declines through health-conscious exercises. Sixty-eight participants were randomly allocated into two groups. The exercise-oriented group (E-group) engaged in twelve 90 min health and exercise sessions over twelve weeks, while the control group (C-group) maintained their regular daily routines and did not receive any specific interventions during this period. The focal point of assessment was driving ability, as evaluated by a person using a real car on public roads without using a simulator. Driving ability and physical fitness were assessed before the intervention in both groups. Post-intervention measurements occurred twelve weeks after the initial gauging, encompassing both cohorts. Comparative analysis of pre- and post-intervention changes was executed between the two groups. The E-group demonstrated improved overall driving ability compared to the C-group. The results suggest that healthy exercise and physical activity may maintain and enhance driving ability for older adults.

The objective of this study was to investigate changes in sedentary and active behaviors when previously inactive adults start exercising in the morning or evening. One-hundred adults with overweight or obesity (BMI ≥ 25 kg/m 2 ) were recruited for a 12-week intervention and randomized to one of three groups: (i) morning exercise (AMEx; 0600-0900); (ii) evening exercise (PMEx; 1600-1900); or (iii) waitlist control. AMEx and PMEx were prescribed self-paced aerobic exercise to achieve a weekly total of 250 min via a combination of supervised and unsupervised training. Sedentary and active behavior times were measured at baseline, mid- and post-intervention using the multimedia activity recall for children and adults. Time spent engaging in physical activity was significantly increased from baseline at both mid- (+ 14-22 min·day -1 ) and post-intervention (+ 12-19 min·day -1 ), for AMEx and PMEx. At 12-weeks, participants in both morning and evening exercise groups reported increased time spent Sleeping (+ 36 and + 20 min·day -1 , respecitively), and reduced time spent watching TV/playing videogames (- 32 and - 25 min·day -1 , respectively). In response to an exercise stimulus, previously inactive adults make encouraging modifications in how they use their time, and the patterns of change are similar with morning and evening exercise., (© 2022.

Background: The Together Everyone Achieves More Physical Activity (TEAM-PA) trial is a randomized controlled trial testing the efficacy of a group-based intervention for increasing physical activity (PA) among insufficiently active African American women., Design: The TEAM-PA trial uses a group cohort design, is implemented at community sites, and will involve 360 African American women. The trial compares a 10-week group-based intervention vs. a standard group-delivered PA comparison program. Measures include minutes of total PA/day using 7-day accelerometer estimates (primary outcome), and body mass index, blood pressure, waist circumference, walking speed, sedentary behavior, light physical activity, and the percentage achieving ≥150 min of moderate to vigorous PA/week (secondary outcomes) at baseline, post-intervention, and 6-months post-intervention., Intervention: The intervention integrates elements from Social Cognitive Theory, Self-Determination Theory, Group Dynamics Theory, and a focus on collectivism to evaluate different components of social affiliation (relatedness, reciprocal support, group cohesion, and collective efficacy). The intervention integrates shared goal-setting via Fitbits, group-based problem-solving, peer-to-peer positive communication, friendly competition, and cultural topics related to collectivism. Compared to the standard group-delivered PA program, participants in the intervention are expected to show greater improvements from baseline to post- and 6-month follow-up on minutes of total PA/day and secondary outcomes. Social affiliation variables (vs. individual-level factors) will be evaluated as mediators of the treatment effect., Implications: The results of the TEAM-PA trial will determine the efficacy of the intervention and identify which aspects of social affiliation are most strongly related to increased PA among African American women., Trial Registration: This study was registered on Clinicaltrials.gov (# NCT05519696) in August 2022 prior to initial participant enrollment., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships what could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Background: Aerobic exercise promotes cognitive function in older adults; however, variability exists in the degree of benefit. The brain-derived neurotropic factor (BDNF) Val66Met polymorphism and biological sex are biological factors that have been proposed as important modifiers of exercise efficacy. Therefore, we assessed whether the effect of aerobic exercise on executive functions was dependent on the BDNFval66met genotype and biological sex., Methods: We used data from a single-blind randomized controlled trial in older adults with subcortical ischemic vascular cognitive impairment (NCT01027858). Fifty-eight older adults were randomly assigned to either the 6 months, three times per week progressive aerobic training (AT) group or the usual care plus education control (CON) group. The secondary aim of the parent study included executive functions which were assessed with the Trail Making Test (B-A) and the Digit Symbol Substitution Test at baseline and trial completion at 6 months., Results: Analysis of covariance, controlling for baseline global cognition and baseline executive functions performance (Trail Making Test or Digit Symbol Substitution Test), tested the three-way interaction between experimental group (AT, CON), BDNFval66met genotype (Val/Val carrier, Met carrier), and biological sex (female, male). Significant three-way interactions were found for the Trail Making Test (F(1,48) = 4.412, p < 0.04) and Digit Symbol Substitution Test (F(1,47) = 10.833, p < 0.002). Posthoc analyses showed female Val/Val carriers benefited the most from 6 months of AT compared with CON for Trail Making Test and Digit Symbol Substitution Test performance. Compared with CON, AT did not improve Trail Making Test performance in male Val/Val carriers or Digit Symbol Substitution Test performance in female Met carriers., Conclusions: These results suggest that future randomized controlled trials should take into consideration BDNF genotype and biological sex to better understand the beneficial effects of AT on cognitive function in vascular cognitive impairment to maximize the beneficial effects of exercise and help establish exercise as medicine for cognitive health., (© 2023.

Background: Increasing physical activity is one of the most promising and challenging interventions to delay or prevent cognitive decline and dementia., Methods: We conducted a randomized controlled trial to assess the effects of a physical activity intervention, aimed at increasing step count, in elderly with low levels of physical activity on measures of strength, balance, aerobic capacity, and cognition. Participants were assigned to 9 months of exercise counseling or active control., Results: The intention-to-treat analyses show that the intervention, compared to control, increases the level of physical activity, but has no significant effect on physical fitness and cognition. Those who increased their physical activity with 35% or more show significant improvements in aerobic capacity, gait speed, verbal memory, executive functioning, and global cognition, compared to those who did not achieve a 35% increase., Limitations: The number of participants that achieved the intended improvement was lower than expected., Conclusion: Responder analyses suggest an improvement of physical fitness and cognition in those who achieved an increase in physical activity of at least 35%., Trial Registration: The trial protocol is registered at the Dutch Trial Register NL5675, August 1, 2016., (© 2023.

RE-AIM is an implementation science framework that provides a structure to promote data collection and analysis in the domains of R each, E fficacy/ E ffectiveness, A doption, I mplementation, and M aintenance. The RE-AIM approach promotes more data collection and reporting than typical evaluations so potential adopters can determine the potential program fit for their setting. RE-AIM has been used to evaluate a variety of programs; however, there are few resources that provide strategies for conducting a RE-AIM evaluation in the school setting. The purpose of this article is to inform future studies by elucidating experiences conducting a large, complex, multisite, longitudinal RE-AIM evaluation in schools in partnership with the state's Departments of Education and Health, and to share strategies for overcoming obstacles. With the long-term goal of facilitating the translation of school-based intervention research into practice, we provide key considerations and recommend strategies for school-based RE-AIM evaluation success.

Background: Physical inactivity is a risk factor for numerous adverse health conditions and outcomes, including all-cause mortality. Aging rural women are at particular risk for physical inactivity based on environmental, sociocultural, and psychosocial factors. This study reports on changes in physical activity and associated factors from a multicomponent community-engaged intervention trial., Methods: Strong Hearts, Healthy Communities 2.0 (SHHC-2.0) was a 24-week cluster (community) randomized controlled trial building on the results from the previous trial of SHHC-1.0. Rural women (n = 182) aged 40 and over living in 11 rural communities in upstate New York were recruited. The intervention consisted of twice-weekly experiential classes focused on exercise, nutrition, and civic engagement. Physical activity outcomes included accelerometry and self-report as well as related psychosocial measures at midpoint (12 weeks) and post-intervention (24 weeks). Data were analyzed using multilevel linear regression models with the community as the random effect., Results: Compared to participants from the control communities, participants in the intervention communities showed a significant increase in objectively measured moderate to vigorous intensity physical activity: at 12 weeks (increase of 8.1 min per day, P < 0.001) and at 24 weeks (increase of 6.4 min per day; P = 0.011). Self-reported total MET minutes per week also increased: at 12 weeks (increase of 725.8, P = 0.003) and 24 weeks (increase of 955.9, P = 0.002). Several of the psychosocial variables also showed significant positive changes., Conclusions: The SHHC-2.0 intervention successfully increased physical activity level and related outcome measures. Modifications made based upon in-depth process evaluation from SHHC-1.0 appear to have been effective in increasing physical activity in this at-risk population., Trial Registration: Clinicaltrials.gov: NCT03059472.

Background: Accompanied by the decline of physiological functions, the decrease of physical activity, and comorbidities, older adults are susceptible to sarcopenia because of accelerated loss of muscle mass. Resistance training is recommended by different clinical practice guidelines. However, most older adults have difficulty in taking recommended high-load resistance training programs, and there are limited exercise options form them. Baduanjin, a traditional Chinese mind-body exercise with relatively low intensity and simple movements, has the potential benefits of improving physical functions and may be feasible in treating sarcopenia and preventing its adverse health outcomes in older patients. With the emergence of the concept of gut-muscle axis, this study aims to determine the efficacy of Baduanjin exercise on Chinese older adults with sarcopenia and explore its underlying mechanism., Methods: This is a 24-week, assessor-blinded, randomized controlled trial. Individuals aged 60 to 84 years old will be screened for sarcopenia. 90 participants with sarcopenia will be enrolled and randomly assigned (1:1) into the Baduanjin exercise or resistance training group, and 20 participants without sarcopenia will be set as the non-sarcopenia control group. The primary outcome is the scores of Short Physical Performance Battery. The secondary outcomes are body composition, handgrip strength, walking speed, global cognitive function, and incidence of falls. These outcomes will be assessed at baseline, the 12th week and the 24th week. While stool samples from participants will be collected at baseline and the 24th week for analyzing the abundance of gut microbiome. Data will be analyzed in an intention-to-treat protocol., Discussion: The results of this study will determine whether Baduanjin exercise can be an alternative non-pharmacological approach for older adults with sarcopenia. If they can show positive significance, it will promote Baduanjin exercise in clinical practice among these patients and inform further research involving exercise interventions on the optimal types, timing, and intensity to ameliorate sarcopenia for elderly people., Trial Registration: Chinese Clinical Trial Registry; Registration number: ChiCTR2100051871; Prospectively registered on October 8th, 2021., (© 2022.

Background: Physical activity is recommended for all pregnant individuals and can prevent excessive gestational weight gain. However, physical activity has not been assessed among military personnel and other TRICARE beneficiaries, who experience unique military lifestyles. The current study assessed physical activity among pregnant TRICARE beneficiaries, both active duty and non-active duty, as measured by accelerometry and self-report data to examine potential predictors of physical activity engagement in the third trimester, and if self-report data was consistent with accelerometry data. We expected having a lower BMI, being active-duty, and having higher baseline physical activity engagement to be associated with higher physical activity at 32-weeks. We also hypothesized that accelerometry data would show lower physical activity levels than the self-reported measure., Methods: Participants were 430 TRICARE adult beneficiaries (204 Active Duty; 226 non-Active Duty) in San Antonio, TX who were part of a randomized controlled parent study that implemented a stepped-care behavioral intervention. Participants were recruited if they were less than 12-weeks gestation and did not have health conditions precluding dietary or physical activity changes (e.g., uncontrolled cardiovascular conditions) or would contribute to weight changes. Participants completed self-report measures and wore an Actical Activity Monitor accelerometer on their wrist to collect physical activity data at baseline and 32-weeks gestation., Results: Based on the accelerometer data, 99% of participants were meeting moderate physical activity guidelines recommending 150 min of moderate activity per week at baseline, and 96% were meeting this recommendation at 32-weeks. Based on self-report data, 88% of participants at baseline and 92% at 32-weeks met moderate physical activity recommendations. Linear regression and zero-inflated negative binomial models indicated that baseline physical activity engagement predicted moderate physical activity later in pregnancy above and beyond BMI and military status. Surprisingly, self-reported data, but not accelerometer data, showed that higher baseline activity was associated with decreased vigorous activity at 32-weeks gestation. Additionally, self-report and accelerometry data had small correlations at baseline, but not at 32-weeks., Conclusions: Future intervention efforts may benefit from intervening with individuals with lower pre-pregnancy activity levels, as those who are active seem to continue this habit., Trial Registration: The trial is registered on clinicaltrials.gov (NCT03057808)., (© 2022.

Physical activity reduces risk of colon cancer by 20-30%. Aberrant methylation patterns are common epigenetic alterations in colorectal adenomas, and cancers and play a role in cancer initiation and progression. Alterations identified in normal colon tissue represent apotential 'field cancerization' process, where normal colon is primed for carcinogenesis. Here, we investigate methylation patterns in three genes -Ena/VASP-like ( EVL ), (CDKN2A (p14, ARF )), and Oestrogen Receptor-1 (ESR1)- in normal colon tissue collected at baseline and 12 months from 202 sedentary men and women, 40-75 years, enrolled in a randomized controlled trial testing an exercise intervention vs. control (http://clinicaltrials.gov/show/NCT00668161). Participants were randomized to moderate-to-vigorous intensity exercise, 60 minutes/day, 6 days/week for 12 months, or usual lifestyle. Sigmoid colon biopsies were obtained at baseline and 12-months, DNA extracted, and bisulphite converted. Droplet digital methylation-specific PCR was performed for EVL, p14ARF , and ESR1 . Generalized estimating equations modification of linear regression was used to model relationships between intervention effects and gene methylation levels, adjusting for possible confounders.There were no statistically significant differences between methylation patterns at 12-months between exercisers and controls. ESR1 methylation patterns differed by sex: women -10.58% (exercisers) +11.10% (controls); men +5.54% (exercisers), -8.16% (controls) ( P =0.05), adjusting for BMI and age. There were no statistically significant changes in methylation patterns in any gene stratified by change in VO 2 max or minutes/week of exercise.While no statistically significant differences were found in gene methylation patterns comparing exercises vs. controls, 12-month exercise effects on ESR1 methylation differed by sex, warranting further study.

Background: Total hip arthroplasty is considered an efficacious procedure for relieving pain and disability, but despite that objectively measured physical activity level remains unchanged compared to pre-surgery and is still considerably lower than that of a healthy age- and sex-matched population 6-12 months post-surgery. Since there is a graded relationship between physical activity level and functional performance, increasing physical activity may enhance the outcome of the procedure. This study aims to investigate whether promotion and support of physical activity initiated 3 months after total hip arthroplasty complementary to usual rehabilitation care can increase objective measured physical activity 6 months post-surgery., Methods: The trial is designed as a pragmatic, parallel group, two-arm, assessor-blinded, superiority, randomized (1:1), controlled trial with post intervention follow-up 6 and 12 months after total hip arthroplasty. Home-dwelling, independent, and self-reliant patients with hip osteoarthritis are provisionally enrolled prior to surgery and re-screened about 2-3 months post-surgery to confirm eligibility. Baseline assessment is conducted 3 months post-surgery. Subsequently, patients (n=200) are randomized to either a 3-month, multimodal physical activity promotion/education intervention or control (no further attention). The intervention consists of face-to-face and telephone counselling, patient education material, pedometer, and step-counting journal. The primary outcome is objectively measured physical activity, specifically the proportion of patients that complete on average ≥8000 steps per day 6 months post-surgery. Secondary outcomes include core outcomes (i.e., physical function, pain, and patient global assessment) and health-related quality of life. Furthermore, we will explore the effect of the intervention on self-efficacy and outcome expectations (i.e., tertiary outcomes)., Discussion: By investigating the effectiveness of a pedometer-driven, face-to-face, and telephone-assisted counselling, behavior change intervention in complementary to usual rehabilitation, we hope to deliver applicable and generalizable knowledge to support physical activity after total hip arthroplasty and potentially enhance the outcome of the procedure., Trial Registration: www., Clinicaltrials: gov NCT04471532 .

Aims: To summarize methods used to account for antihyperglycemic medication changes in randomized controlled trials evaluating the effect of dietary and physical activity interventions on glycemia among adults with diabetes., Methods: Using studies included in two recently published systematic reviews of randomized controlled trials examining the glycemic effects of dietary and physical activity interventions, we evaluated how each study accounted for antihyperglycemic medication changes. Data were analyzed using summary statistics, stratified by the type of intervention studied, and each was assigned a score from 0 to 6 reflecting the strength of medication controls employed., Results: We evaluated 22 physical activity focused and 27 dietary focused articles. Our scoring system yielded a mean concurrent medication adjustment score of 3.9/6 for the physical activity studies and a score of 1.7/6 ( p < 0.001) for the dietary studies., Conclusions: We found that randomized controlled trials included in recent systematic reviews of physical activity and dietary interventions did not robustly account or control for changes in antihyperglycemic medications, with physical activity interventions doing so more robustly than dietary interventions. This is a threat to the validity of study findings, as observed glycemic changes may in fact be attributable to imbalances in concurrent medication adjustments between groups.

Healthy dietary intake and physical activity reduce the risk of non-communicable diseases. This systematic review and meta-analysis aimed to examine the effect of interventions including both nutrition and physical activity provided by nutrition and exercise practitioners for adults in the general population (those without diagnosed disease). The MEDLINE, CINAHL, Cochrane Central, Cochrane Database of Systematic Reviews and SportDiscus databases were searched for randomized controlled trials (RCTs) published from 2010 until April 2021. Outcomes included physical activity, fruit and vegetable intake, waist circumference, percent weight loss, quality of life (QoL) and adverse events. Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods were used to synthesize and grade evidence. Meta-analyses were stratified according to participant health status. The database search identified 11,205 articles, and 31 RCTs were included. Interventions increased physical activity amount [standardized mean difference (SMD) (95% CI): 0.25 (0.08, 0.43)] (low certainty evidence); increased vegetable intake [SMD (95% CI): 0.14 (0.05, 0.23)] (moderate certainty evidence); reduced waist circumference [MD (95% CI): -2.16 cm (-2.96, -1.36)] (high certainty evidence); and increased likelihood of achieving 5% weight loss for adults with overweight and obesity [relative risk (95% CI): 2.37 (1.76, 3.19)] (high certainty evidence). Very low and low certainty evidence described little-to-no effect on QoL or adverse events. Nutrition and exercise practitioners play key roles in facilitating positive lifestyle behaviors to reduce cardiometabolic disease risk in adults.

Background: Randomized controlled trials (RCTs) are the gold standard for generating evidence to inform clinical oncology practice. Knowledge gained through qualitative research methodologies can be complementary to that gained through RCTs. How qualitative research has been combined with RCTs in oncology has not been previously characterized., Objective: This scoping review was conducted to summarize how qualitative research associated with RCTs in the oncology setting has been conducted and examine the quality of reporting., Eligibility Criteria: Manuscripts reporting on qualitative research linked with RCTs in the cancer context that involved patients (both adult and pediatric) and/or informal caregiver (friends/family) were included., Sources of Evidence: Peer-reviewed manuscripts indexed in MEDLINE (OVID) and CINAHL, published in English between 2008 and January 2019., Charting Methods: Formal scoping review methods were followed. A data extraction tool informed by the research questions as well as the COnsolidated criteria for REporting Qualitative research (COREQ) was utilized. Extraction was conducted independently by two authors, with disagreements resolved by a third., Results: Fifty-four articles were included. Assessing information sharing, diet/exercise, and psychotherapeutic interventions were the most common focuses of the RCTs. The most common focus of the qualitative component was on gaining insight into the experience of receiving the intervention or participating in RCT procedures. How the intervention impacted the cancer experience was not a common focus of the qualitative components. Some reports provided insufficient information to understand how the qualitative components aligned with the RCT components. The results of the qualitative and RCT components were not integrated to draw meaningful conclusions about the efficacy of the intervention under study in most cases. Reports focusing on only qualitative methods had higher median (Mdn) reporting of COREQ items compared to reports that included both the qualitative and RCT components (Mdn = 18 vs. Mdn = 14, respectively; p <0.001)., Conclusions: This review identified that qualitative research has been combined with RCTs in the cancer context in a number of ways, most commonly to understand the experience of receiving study interventions or participating in trial procedures. Exploring how interventions impact other aspects of the cancer experience is an approach that should be considered in future work. Formalized guidelines for the design and reporting of investigations that combine qualitative and RCT approaches in the cancer context are expected to be of value., Tweetable Abstract: Combining qualitative research with randomized controlled trials in oncology: an impornt opportunity for discovery., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022.

Background: New intensive trauma-focused treatment (TFT) programmes that incorporate physical activity have been developed for people with post-traumatic stress disorder (PTSD). However, the unique contribution of physical activity within these intensive TFT programmes has never been investigated in a controlled manner., Objectives: This randomized controlled trial will investigate the effectiveness of physical activity added to an intensive TFT programme. In addition, the study aims to investigate the underlying mechanisms of the effects of physical activity on the change in PTSD symptoms., Methods: Individuals with PTSD ( N = 120) will be randomly allocated to two conditions: a physical activity or a non-physical active control condition. All participants will receive the same intensive TFT lasting eight days within two consecutive weeks, in which daily prolonged exposure and EMDR therapy sessions, and psycho-education are combined. The amount of physical activity will differ per condition. While the physical activity condition induces daily physical activities with moderate intensity, in the non-physical active control condition no physical activity is prescribed; but instead, a controlled mixture of guided (creative) tasks is performed. The two primary outcome measures are change in PTSD symptoms from pre- to post-treatment and at six months follow-up, measured with the Clinician-Administered PTSD Scale (CAPS-5), and the PTSD Checklist for DSM-5 (PCL-5). Additionally, self-reported sleep problems, depressive symptoms, emotion regulation, dissociation symptoms and anxiety sensitivity will be measured as potential underlying mechanisms., Conclusions: This study will contribute to the research field of augmentation strategies for PTSD treatment by investigating the effectiveness of physical activity added to intensive TFT., Trial Registration: This trial is registered in the Netherlands Trial Register (Trial NL9120)., Competing Interests: Agnes Van Minnen receives income for published book chapters on PTSD and for the training of postdoctoral professionals in prolonged exposure. Ad De Jongh receives income from published books on EMDR therapy and for the training of postdoctoral professionals in this method.

Background: Effective concepts are required to overcome the negative impact of daily stressful overwhelming. We investigated the effectiveness of a 1-week multimodal program for stress reduction., Methods: We performed a randomized controlled trial including adults with above-average stress level. The intervention consisted of health coaching, relaxation, physical activity, and balneotherapeutic elements. Individuals were randomized either to the intervention group (IG) or to one of the two control groups B and C. The main outcome was change in stress (Perceived Stress Questionnaire [PSQ], Screening Scale of Chronic Stress of the Trier Inventory for Chronic Stress [TICS-SSCS]) at 6 months post intervention; further outcomes were well-being (World Health Organization 5-Item Well-Being Index [WHO-5]) and health status (EuroQol visual analog scale [EQ-5D VAS]). Data were collected pre/post intervention as well as after 1, 3, and 6 months., Results: Data of 96 individuals (mean age 48.0 years, 74% female) were available for analyses. The IG improved overtime with -13.45 points for the PSQ and -6.44 points for the TICS-SSCS after 6 months. At 6-month follow-up the IG did not significantly differ from group B (PSQ: p = 0.2332; TICS-SSCS: p = 0.0805) or group C (PSQ: p = 0.0950; TICS-SSCS: p = 0.0607) when controlling for baseline (ANCOVA). Compared to group C, ANCOVA revealed significant differences in WHO-5 (p = 0.0292) and EQ-5D VAS (p = 0.0177) post intervention. At the 3- and 6-month follow-up and compared to group B, no substantial differences could be found for WHO-5 and EQ-5D VAS., Conclusion: The results indicate that even a short-term multimodal program for stress reduction appears to set a positive trend towards less perceived and chronic stress., (© 2021 S.

The preschool age seems to be decisive for the development of motor skills and probably the most promising time-window in relation to improvement of motor skills. This trial investigates the effect of an intensive structured intervention to improve motor skills in 3-6-year-old preschool children. A total of 471 Danish preschool children participated in a cluster randomized controlled trial. The intervention was to enhance motor skills, including predefined minimum criteria. Motor skills were measured using the Motor Assessment Battery for Children-2 (MABC-2) (total and three domains) at baseline and 6-, 18-, and 30-months post-intervention. The effect was estimated by multilevel linear regression with preschool and child included as random effects and adjusted for baseline values. Effect estimates were mainly positive at 6 months, but negative at 30 months with very few statistically significant estimates. In preschools with baseline motor skills scores below average, there was a tendency towards a larger improvement in the intervention group. Future interventions and research should focus on clusters with poor motor skills, as there is larger room for improvement. It remains to be seen whether the intervention can influence general well-being, physical activity, and self-perceived competence, both short- and long-term.

Background: Consumption of a Mediterranean diet, adequate levels of physical activity, and energy-restricted lifestyle interventions have been individually associated with improvements in HDL functions. Evidence of intensive interventions with calorie restriction and physical activity is, however, scarce., Objectives: To determine whether an intensive lifestyle intervention with an energy-restricted Mediterranean diet plus physical activity enhanced HDL function compared to a non-hypocaloric Mediterranean eating pattern without physical activity., Methods: In 391 older adults with metabolic syndrome (mean age, 65 years; mean BMI, 33.3 kg/m2) from 1 of the Prevención con Dieta Mediterránea-Plus trial centers, we evaluated the impact of a 6-month intervention with an energy-restricted Mediterranean diet plus physical activity (intensive lifestyle; n = 190) relative to a nonrestrictive Mediterranean diet without physical activity (control; n = 201) on a set of HDL functional traits. These included cholesterol efflux capacity, HDL oxidative/inflammatory index, HDL oxidation, and levels of complement component 3, serum amyloid A, sphingosine-1-phosphate, triglycerides, and apolipoproteins A-I, A-IV, C-III, and E in apoB-depleted plasma., Results: The intensive-lifestyle intervention participants displayed greater 6-month weight reductions (-3.83 kg; 95% CI: -4.57 to -3.09 kg) but no changes in HDL cholesterol compared with control-diet participants. Regarding HDL functional traits, the intensive lifestyle decreased triglyceride levels (-0.15 mg/g protein; 95% CI: -0.29 to -0.014 mg/g protein) and apoC-III (-0.11 mg/g protein; 95% CI: -0.18 to -0.026 mg/g protein) compared to the control diet, with weight loss being the essential mediator (proportions of mediation were 77.4% and 72.1% for triglycerides and apoC-III levels in HDL, respectively)., Conclusions: In older adults with metabolic syndrome, an energy-restricted Mediterranean diet plus physical activity improved the HDL triglyceride metabolism compared with a nonrestrictive Mediterranean diet without physical activity.

Rationale: Although effects of individual planning interventions on physical activity (PA) are well established, less is known about the relationships between planning and sedentary behavior (SB)., Objective: This study evaluated the efficacy of individual planning, dyadic planning (i.e., joint planning, targeting the behavior of one person only: the target person), and collaborative planning (i.e., joint planning and joint behavioral performance) on sedentary behavior among dyads., Methods: Dyads (N = 320 target persons and their partners, aged 18-90 years) were randomized into three PA planning conditions (individual, dyadic, or collaborative) or an active (education) control condition. Main outcomes, i.e., sedentary time, proportion of time spent in SB and light-intensity PA, proportion of time spent in SB and total PA were measured with GT3X-BT accelerometers at baseline, 1-week follow-up, and 36-week follow-up. Two-level models with measurement points nested in participants were fit, separately for target persons and partners., Results: Findings for target persons obtained at 1-week follow-up indicated that in the collaborative planning condition SB time significantly decreased, compared to the control condition (p = .013). There was an improvement in the proportion of time spent in SB and light-intensity PA (p = .019), and the proportion of time spent in SB and total PA (p = .018), indicating that SB time was displaced by PA. Effects of individual and dyadic planning were not significant, compared to the control condition. None of interventions had a significant effect on SB indices at 36-week follow-up. Regarding dyadic partners, there were no effects of planning interventions at 1-week follow-up or 36-week follow-up, compared to the control condition., Conclusions: Collaborative planning may prompt a short-term reduction of SB time and result in a shift towards a healthier balance between SB time and PA time among target persons, who did not adhere to PA guidelines at baseline., (Copyright © 2021 The Authors.

Background/objectives: The current systematic review and meta-analysis evaluated the relationship between the form of exercise and changes in resting blood pressure (RBP) in older adults and the overall level of evidence., Methods: The inclusion criteria were studies involving intervention with only regular exercise limited to subjects ≥65 years old. The combined changes in RBP in each study were calculated and the relationship between the form of exercise and changes in the RBP were evaluated. The overall evidence was assessed using the GRADE approach., Results: Nineteen studies (1081 subjects) were analyzed. The combined changes in the RBP decreased as a result of aerobic exercise or resistance exercise. The intensity of resistance exercise (METs) was related to the change in the RBP of systolic (meta-regression coefficient, -2.5 [95% confidence interval, -4.7 to -0.4]; R 2 =35.4%). When excluding studies with high overall risk of bias, the overall duration of aerobic exercise (weeks) was related to the change in the RBP of systolic (meta-regression coefficient, -0.6 [95% confidence interval, -1.0 to -0.2]; R 2 =93.2%). In addition, there was a low level of evidence overall for a decrease in RBP as a result of aerobic exercise, but there was a moderate level of evidence for a decrease in RBP as a results of resistance exercise., Conclusion: A decrease in the RBP of systolic may be associated with active exercise in older adults. However, there may be insufficient evidence for the decrease in RBP as a result of aerobic exercise., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Aim: To examine the effectiveness of physical activity (PA) interventions on changes in PA among colorectal cancer survivors, including an examination of theoretical versus atheoretical-driven approaches, with a special focus on their effectiveness across ethnic and racial minorities., Design: Systematic review with aggregated data meta-analyses., Data Sources: Using six databases (Cochrane Central Register of Controlled Trials, PubMed, PsycINFO, CINAHL with full text, Scopus and Web of Science), we will screen for randomized controlled trials written in English from May 1, 1993 up to December 31, 2020., Review Methods: Dual study-selection and data abstraction will be performed. The Behavior Change Technique Taxonomy (v1) will be used to examine behavior change techniques among selected studies, while the Theory Coding Scheme will be used to assess the extent of theory use. Risk of bias will be assessed using the revised Cochrane risk-of-bias tool for randomized trials, while the strength of the evidence will be assessed using the Grading of Recommendations Assessment, Development, and Evaluation instrument. In addition, intervention delivery will be appraised using the Template for Intervention Description and Replication. Changes in PA from each study will be calculated using the standardized mean difference effect size (Hedge's g). Results will be pooled using the inverse-variance heterogeneity model. Heterogeneity (Cochran's Q) and inconsistency (I 2 ) will be examined, while small-study effects (publication bias) will be evaluated using the Doi plot and LFK Index. Meta-regression will also be conducted to examine for potential associations between changes in physical activity and selected covariates (theoretical versus atheoretical-driven approaches, race/ethnicity)., Discussion: This systematic review will identify specific racial/ethnic minorities for whom interventions are most effective and summarize the evidence of the effectiveness of theoretical vs. theoretical based intervention., Impact: This systematic review can direct policymakers and practitioners towards actions that are likely to bring about positive physical activity behaviour change., (© 2021 John Wiley & Sons Ltd.)

Physical activity interventions for youth are direly needed given low adherence to physical activity guidelines, but many interventions suffer from low user engagement. Exergames that require bodily movement while played may provide an engaging form of physical activity intervention but are not perceived as engaging to all. This study aimed to evaluate whether dynamic tailoring in a narrative-driven mobile exergame for adolescents played in leisure settings, can create higher user engagement compared to a non-tailored exergame. A cluster-randomized controlled trial assessed differences in user engagement between a dynamically tailored (based on an accelerometer sensor integrated in a T-shirt) and non-tailored condition. In total, 94 participants (M age = 14.61 ± 1.93; 35% female) participated and were assigned to one of the two conditions. User engagement was measured via a survey and game metric data. User engagement was low in both conditions. Narrative sensation was higher in the dynamically tailored condition, but the non-tailored condition showed longer play-time. User suggestions to create a more appealing game included simple and more colorful graphics, avoiding technical problems, more variety and shorter missions and multiplayer options. Less cumbersome or more attractive sensing options than the smart T-shirt may offer a more engaging solution, to be tested in future research.

Objective: This study aimed to develop and assess additional effects of brief self-exercise education (brief-See) for individuals with chronic low back pain (CLBP). The brief-See comprised 100-minute consultation, individualized self-exercise program, and direct short teaching., Methods: We conducted a 6-month, community-based, randomized, parallel-group trial in a community setting, and allocated into a brief-See or material-based education alone. Pain intensity (NRS, numeric rating scale), functional limitation (RDQ, Roland-Morris disability questionnaire), self-efficacy (PSEQ, pain self-efficacy questionnaire), and quality of life (EQ-5D, European quality of life-5 dimensions) were evaluated at 4, 12, and 24 weeks after the initial consultation., Results: The brief-See did not show additional improvement over material-based education on the NRS, but it did on the RDQ, PSEQ, and EQ-5D; the estimated mean group differences in changes from the baseline were -2.1 (-3.5 to -0.7, p  = .005) on the RDQ, 6.9 (1.7-12.1, p  = .010) on the PSEQ, and 0.07 (0.02-0.12, p  = .004) on the EQ-5D., Conclusion: The 100 minutes' education program could be more acceptable, and restores functional limitation, self-efficacy, and quality of life in addition to the effects of material-based education. This has the potential to contribute to the management of CLBP in a community.

Sedentary behavior increases the risk for multiple chronic diseases, early mortality, and accelerated cognitive decline in older adults. Interventions to reduce sedentary behavior among older adults are needed to improve health outcomes and reduce the burden on healthcare systems. We designed a randomized controlled trial that uses a self-affirmation manipulation and gain-framed health messaging to effectively reduce sedentary behavior in older adults. This message-based intervention lasts 6 weeks, recruiting 80 healthy but sedentary older adults from the community, between the ages of 60 and 95 years. Participants are randomly assigned to one of two groups: 1) an intervention group, which receives self-affirmation followed by gain-framed health messages daily or 2) a control group, which receives daily loss-framed health messages only. Objective physical activity engagement is measured by accelerometers. Accelerometers are deployed a week before, during, and the last week of intervention to examine potential changes in sedentary time and physical activity engagement. Participants undertake structural and functional (resting and task-based) MRI scans, neuropsychological tests, computerized behavioral measures, and neurobehavioral inventories at baseline and after the intervention. A 3-month follow-up assesses the long-term maintenance of any engendered behaviors from the intervention period. This study will assess the effectiveness of a novel behavioral intervention at reducing sedentarism in older adults and examine the neurobehavioral mechanisms underlying any such changes., (Copyright © 2021 Elsevier Inc.

We aimed to evaluate the feasibility of multidomain intervention (MI) tailored to the Korean context. In an outcome assessor-blinded, randomized controlled trial, participants without dementia and with one or more modifiable dementia risk factors, aged 60-79 years, were randomly assigned to the facility-based MI (FMI; n=51), the home-based MI (HMI; n=51), or the control group receiving general health advice (n=50). The 24-week intervention comprised vascular risk management, cognitive training, social activity, physical exercise, nutrition guidance, and motivational enhancement. The FMI participants performed all intervention programs at a facility three times a week. The HMI participants performed some programs at a facility once every 1-2 weeks and performed others at home. The primary outcome was feasibility measured through retention, adherence, and at least no differences from the control group in the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). In the FMI and HMI groups, the retention rates were 88.2% and 96.1%, and adherence to the intervention was 94.5% and 96.8%, respectively. The RBANS total scale index score improved significantly in the FMI (5.46 ± 7.50, P = 0.004) and HMI (5.50 ± 8.14, P = 0.004) groups compared to the control group (-0.74 ± 11.51). The FMI and HMI are feasible and there are indicators of efficacy.

Background: Studies suggest that Schisandra chinensis Baillon (Sc) may enhance muscle strength and mass because of its anti-inflammatory and antioxidant properties., Objectives: We aimed to examine the effects and safety of consumption of Sc extract (SCe) for 12 wk on muscle strength and mass in older adults with relatively low muscle mass who do low-intensity exercise., Methods: A randomized, double-blind, placebo-controlled trial was performed in adults >50 y of age. Fifty-four participants were randomly assigned into 2 groups and, for 12 wk, received either 1 g SCe/d or a placebo. All participants were required to walk for 30-60 min/d for >3 d/wk during the trial period. At baseline and at 4 and 12 wk after treatment, the participants were examined for knee extension strength using Biodex isokinetic dynamometers, handgrip strengths, and body composition, and blood tests were performed. The Euro-QoL-5D (EQ-5D) questionnaire and the FFQ were administered at baseline and at 12 wk after treatment. Physical activity was assessed using a self-recorded daily exercise log and an accelerometer during the study., Results: SCe supplementation over 12 wk caused a higher increase in right knee extensor strength by 10.2 Nm (95% CI: 3.7, 16.8 Nm; P = 0.003) and left knee extensor strength by 6.7 Nm (95% CI: 0.3, 13.1 Nm; P = 0.041) than did the placebo. However, no differences were observed in the muscle mass, anti-inflammatory markers, antioxidative markers, and EQ-5D score between the groups. None of the participants experienced adverse events., Conclusions: SCe supplementation may enhance skeletal muscle strength but not mass in older adults who perform low-intensity exercise. This trial was registered at clinicaltrials.gov as NCT03402308., (© The Author(s) 2021. Published by Oxford University Press on behalf of the American Society for Nutrition.)

Self-reported physical activity differs from activity levels measured by device. We tested the effect of a video that visualizes the intensity levels of physical activity to increase the agreement between self-reported and accelerometer-based moderate-to-vigorous physical activity (MVPA) within a single-blinded, randomized study. Participants (N = 378, 40-75 years) wore an accelerometer for seven days. Prior to the collection of self-reported data by the IPAQ-SF, participants were randomly assigned (1:1) to a control group (CG) or a video group (VG). The outcome was the absolute difference between self-reported and accelerometer-based time spent in MVPA (Δ MVPA IPAQ-Accelerometry ). To examine the agreement, we used Spearman correlation coefficients and Bland-Altman analysis. To test the video effect, we used Wilcoxon signed-rank test, Bayes factor, and simultaneous-quantile regression. In total, 302 participants fulfilled the accelerometer wear time criteria (≥10 hours/day; ≥6 days) and completed self-reports within three days after the wearing period. The median of Δ MVPA IPAQ-Accelerometry was -9.0 min/day (IQR: -32.0 to 66.6) for CG and -11.5 min/day (IQR: -29.9 to 14.3) for VG. Wilcoxon signed-rank test revealed no differences in Δ MVPA IPAQ-Accelerometry between study groups whereas Bayes factor indicated insensitivity of the data. Simultaneous-quantile regression revealed no relationship between video presentation and Δ MVPA IPAQ-Accelerometry in the 25th percentile. In the 50th (b = -12.4 [95% CI = -23.2 to -1.5] and 75th percentile (b = -45.7 [95% CI = -70.5 to -20.9]), Δ MVPA IPAQ-Accelerometry was negatively associated with video presentation. To conclude, video-supported assessment may increase the accuracy of self-reported MVPA among individuals who slightly underestimated and those who overestimated their MVPA., (© 2021 The Authors.

Objective: To determine the effectiveness of a person-centred intervention, including advice on physical activity, for improving pain intensity, physical activity, and other health-related outcomes in persons with chronic widespread pain , when delivered with digital eHealth support compared with standard telephone follow-up., Design: Randomized controlled trial., Subjects: Individuals with chronic widespread pain (n = 139), aged 20-65 years, who had previously participated in a pain educational programme at primary healthcare units, were contacted during the period 2018-19 and randomized to an intervention group (n = 69) or an active control group (n = 70)., Methods: Together with a physiotherapist, participants in both groups developed person-centred health plans for physical activity. The intervention group was supported via a digital platform for 6 months. The active control group received support via one follow-up phone call. Primary outcome was pain intensity. Secondary outcomes were physical activity and other health-related outcomes., Results: No significant differences were found between the groups after 6 months, except for a significant decrease in global fatigue in the active control group compared with the intervention group., Conclusion: Future development of interventions supporting persons with chronic pain to maintain regular exercise is warranted.

Background: Physical exercise is suggested to be effective for preventing cognitive decline in older adults, but the relative efficacy of different types of exercise have yet to be clarified., Objective: This single-blinded randomized controlled trial was designed to investigate the differential effects of aerobic exercise training (AT), resistance exercise training (RT), and combined exercise training (CT) on cognition in older adults with subjective memory complaints (SMC)., Methods: Community-dwelling older adults with SMC (n = 415; mean age = 72.3 years old) were randomly assigned to one of the four groups: AT, RT, CT, or control group. The study consisted of two phases: a 26-week intervention and a 26-week follow-up. The participants were evaluated at baseline, 26 weeks (postintervention), and 52 weeks (follow-up). The primary outcome of this study was memory function, which was assessed using the Logical Memory II subtest of the Wechsler Memory Scale-Revised (WMS-R) score. The secondary outcomes included global cognitive function, verbal fluency, working memory, processing speed, and executive functions., Results: Intention-to-treat analysis by a mixed-effect model repeated measure showed that the AT group had significantly improved performance on the WMS-R Logical Memory II test (2.74 [1.82-3.66] points) than the control group (1.36 [0.44-2.28] points) at the postintervention assessment (p = 0.037). The effect was more pronounced in those without amnesia than those with amnesia. No significant improvement was observed in the RT and CT groups., Conclusion: This study suggests that AT intervention can improve delayed memory in community-dwelling older adults, particularly in individuals without objective memory decline.

Purpose: Limited research has measured the effect of physical activity (PA) interventions on health-related quality of life (HRQoL) among pre-school-aged children. This study evaluates the effect of the Activity Begins in Childhood (ABC) cluster-randomized controlled trial designed to increase PA in the ages 3-5 years on HRQoL., Methods: This was a cluster-randomized controlled trial where the intervention group included PA education delivered to daycare providers only, or daycare providers and parents. In the current study, the two PA intervention groups were combined. The comparator group received standard daycare curriculum (COM). A total of 215 children were included (PA n = 161, COM n = 54). Parents completed the proxy Pediatric Quality of Life Inventory Generic Core Scale (PedsQL™ 4.0) to measure HRQoL at baseline and the end of the 6-month trial. HRQoL scores were analyzed as physical, psychosocial, and total domains. Baseline and 6-months measurements were compared for PA and COM groups, and mean changes in scores (95% confidence intervals) were measured using absolute values., Results: No between-group differences were observed for the physical (p = 0.17), psychosocial (p = 0.95) or total scores (p = 0.20). Paired comparisons showed that only the PA group improved psychosocial- (PA mean difference = 2.18 (0.20, 4.15), p = 0.03; COM mean difference = 2.05 (- 1.03, 5.13), p = 0.19) and total-HRQoL scores (PA mean difference = 2.83 (1.83, 3.84), p < 0.001; COM mean difference = 0.19 (- 1.78, 2.16), p = 0.84) after 6 months., Conclusion: Although the within-PA group analysis showed an improvement in psychosocial and total HRQoL scores from baseline, no between-group differences were observed in the HRQoL over time among children aged 3-5 years.

Objectives: Decreased workforce productivity has a significant economic impact on healthcare systems. Presenteeism, the practice of working at reduced potential, is more harmful than absenteeism. Present workers most often experience musculoskeletal pain that is not mitigated by general exercise or stretching. We aimed to assess whether a regimen of pain neuroscience education (PNE) and exercise tailored to individual healthcare workers could reduce presenteeism and improve productivity., Methods: An independent investigator randomized 104 medical professionals into two groups (intervention and control). The control group received general feedback after answering a questionnaire, while the intervention group received a 6-month plan of exercises and PNE created by a physical therapist with 10 years of experience. Our primary outcome was the scores of the Japanese version of the World Health Organization Health and Work Performance Questionnaire (WHO-HPQ) to investigate presenteeism; and our secondary outcomes were pain intensity, widespread pain index (WPI), and EuroQol 5-dimension (EQ5D-5L)., Results: In the intervention group, post intervention, we observed significant improvement in presenteeism, pain intensity, WPI, physical and psychological stress, and EQ5D-5L (P < .05). In the control group, we noted significant improvement only in the physical and psychological stress post intervention (P < .05). The results showed significant between-group differences in presenteeism post-intervention (P < .05)., Conclusion: We demonstrated that a combination of PNE and exercise decreases presenteeism of healthcare workers. Our findings will help healthcare facilities carry out better employee management and ensure optimal productivity., (© 2021 The Authors.

Background and Aims: To examine the effects of aerobic training (AT) and resistance training (RT) compared to standard care on glycemic control in South Asian Sri Lankan adults with Type 2 Diabetes Mellitus (T2DM)., Methods: Randomized controlled trial (RCT) with parallel-group design recruited 86 sedentary Sri Lankans (aged 35-65 years) with T2DM into aerobic training (AT, n = 28), resistance training (RT, n = 28) and control (CN, n = 30) groups. Supervised progressive exercise training consisting of 75 min per session, 2 days per week for 12 weeks was conducted. The primary outcome was pre- and post-intervention absolute change in hemoglobin A1c (HBA1c). Secondary outcomes were serum lipids, liver enzymes, chronic inflammatory status, anthropometry, body composition and blood pressure., Results: The absolute change in HbA1c of RT vs. CN was -0.08% (95% CI, 0.8% to -0.7%, p = 0.8) and AT vs. CN was -0.22% (95% CI, 0.95% to -0.5%). Subgroup analysis (n = 49) with a high baseline HbA1c (>7.5%), absolute reduction in HbA1c in exercise groups were statistically significant (RT vs. CN was -0.37%; 95% CI 1.3% to -0.6%, p = 0.04 and AT vs. CN was -0.57%; 95% CI 1.7% to -0.6%, p = 0.03). The effect sizes (total and subgroup HbA1c >7.5%) ranged from 0.7 to 1.0 in AT, 0.4 to 1.1 in RT compared to 0.35 to 0.6 for the CN. Secondary outcomes did not significantly differ among groups., Conclusions: Exercise training 2 days/week improved glycemic control in Sri Lankan adults with T2DM and the effects were significant in high baseline HbA1c (>7.5%) groups (RT > AT)., Competing Interests: Declaration of competing interest Authors declare no conflicts of interests., (Copyright © 2020 Diabetes India.

Sleep deprivation and emotional problems such as stress, anxiety, and depression commonly occur in university students. Exercise is beneficial to ameliorate those problems; however, university students are not serious to take up physical activity. Commercially available exergame such as Xbox ® 360 Kinect is one of the alternatives. This study aims at investigating the feasibility and the potential efficacy of using Xbox 360 Kinect game among health care undergraduate students. A pilot two-armed parallel randomized controlled trial was implemented. A total of 36 undergraduate students was recruited and randomly allocated into the intervention group (playing Xbox 360 Kinect) or the control group (continue with normal daily routine). The intervention group received 30 minutes of Xbox Kinect activity, three times per week for 6 weeks. Information on psychology (Depression, Anxiety, and Stress Scale-21) and sleep (Functional Outcome Sleep Questionnaire-30) status was collected at pre- and post-experiment. The researcher-developed feasibility questionnaire was given to the participants in the intervention group at post-experiment. Repeated-measures analysis of variance was used to investigate within-between group comparison, and significance value was set at p  ≤ 0.05. The analysis found potential improvement on sleep ( p  = 0.039) and psychological health ( p  = 0.002-0.067). The intervention protocol is feasible and highly accepted by the participants. The required optimum amount of dosage, sample size, and the use of outcome measures are suggested from the findings. This pilot and feasibility study supports the use of Xbox 360 Kinect games in practice and to be implemented for future research.

Objectives: The aim of this study was to report preplanned secondary analyses of the effects of a 12-month individualized active aging counseling intervention on six mobility and physical activity outcomes. Methods: A two-arm, single-blinded randomized controlled trial was conducted among 75- and 80-year-old community-dwelling people. The intervention group (IG, n = 101) received counseling aimed at increasing self-selected, primarily out-of-home activity. The control group (CG, n = 103) received general health information. Data were analyzed with generalized estimating equations. Results: Physical performance improved in the IG more than that in the CG (group by time p = .022), self-reported physical activity increased in both groups (time p = .012), and autonomy in outdoor mobility declined in the IG and was enhanced in the CG (group by time p = .011). No change was observed for life-space mobility, proportion of persons perceiving difficulty walking 2 km, or monitored physical activity. Discussion: Individualized counseling aiming at increasing self-selected out-of-home activity had nonsystematic effects on mobility and positively affected physical performance only.

Background: Physical activity (PA) declines throughout adolescence, therefore PA promotion during this period is important. We analyzed the effect of two school-based PA interventions on daily PA levels, cardiorespiratory fitness (CRF) and muscle strength among adolescents., Methods: For the nine-month School in Motion intervention study (ScIM), we cluster-randomized 30 Norwegian secondary schools (N = 2084, mean age [SD] = 14 [0.3] years) to one of three study arms. The physically active learning (PAL) intervention included 30 min physically active learning, 30 min PA and a 60 min physical education (PE) lesson per week. The Don't worry-Be happy (DWBH) intervention included a 60 min PA lesson and a 60 min PE lesson per week, both tailored to promote friendships and wellbeing. Both intervention arms were designed to engage the adolescents in 120 min of PA per week in addition to recess and mandatory PE lessons. The control group continued as per usual, including the standard amount of mandatory PE. PA (main outcome) was assessed by accelerometers, CRF and muscle strength (secondary outcomes) were assessed by an intermittent running test and selected tests from the Eurofit test battery., Results: Daily PA and time spent in moderate- to vigorous-intensity PA (MVPA) decreased in all groups throughout the intervention. The mean difference in PA level and MVPA for participants in the PAL-intervention arm was 34.7 cpm (95% CI: 4.1, 65.3) and 4.7 min/day (95% CI: 0.6, 8.8) higher, respectively, compared to the control arm. There were no significant intervention effects on daily PA level, MVPA or time spent sedentary for adolescents in the DWBH-intervention arm. Adolescents in the PAL-intervention arm increased distance covered in the running test compared to controls (19.8 m, 95% CI: 10.4, 29.1), whilst a negative intervention effect was observed among adolescents in the DWBH-intervention arm (- 11.6 m, 95% CI: - 22.0, - 1.1)., Conclusion: The PAL-intervention resulted in a significantly smaller decrease in daily PA level, time spent in MVPA, and increased CRF compared to controls. Our results indicate that a teacher-led intervention, including three unique intervention components, is effective in curbing the decline in PA observed across our cohort and improving CRF., Trial Registration: ClinicalTrials.gov ID nr: NCT03817047 .
