Background: The knowledge base on physical activity and sedentary behaviour in adults with Down syndrome (DS) may advance by accelerometer calibration studies. This study aimed to develop cut‐points for sedentary behaviour and moderate‐to‐vigorous physical activity (MVPA) for adults with DS based on output from accelerometers worn on the dominant and non‐dominant hips. Methods: Sixteen adults with DS (10 men; age 31 ± 15 years) performed 12 tasks including sedentary behaviours and physical activities. We obtained metabolic equivalents (METs) with indirect calorimetry and vector magnitude (VM) output from triaxial accelerometers (wGT3X‐BT, ActiGraph) worn on the dominant and non‐dominant hips. Receiver operating characteristic curves were used to identify optimal VM cut‐points that maximised sensitivity and specificity. Results: Overall classification accuracy was very high (area under the ROC curve: 0.95 and 0.92 for sedentary and MVPA models, respectively). For the non‐dominant hip, the optimal VM cut‐points were (1) sedentary behaviour ≤236 counts·min−1 and (2) MVPA ≥2167 counts·min−1. For the dominant hip, optimal cut‐points were (1) sedentary behaviour ≤243 counts·min−1 and (2) MVPA ≥2092 counts·min−1. Conclusions: The presented VM cut‐points for sedentary behaviour and MVPA for adults with DS had high classification accuracy. There were small differences in accelerometer cut‐points between the dominant and non‐dominant hip. [ABSTRACT FROM AUTHOR]

Background: Triaxial accelerometer output [vector magnitude (VM) counts] may better estimate physical activity intensity as reflected in the rate of oxygen uptake (V̇O2) than the traditional vertical axis (VA) counts in adults with Down syndrome (DS). This study examined the accuracy of VM vs. VA counts in estimating V̇O2 in adults with and without DS across different physical activities and sedentary behaviours. Methods: Sixteen adults with DS (10 men and 6 women; 31 ± 15 years) and 19 adults without DS (10 men and 9 women; 24 ± 5 years) performed 12 tasks. V̇O2 was measured by portable spirometer (K4b2, Cosmed) and VM and VA with an accelerometer (wGT3X‐BT, Actigraph). Results: Vector magnitude and VA were significant predictors of V̇O2 in adults with DS (P < 0.001; R2 = 0.74 and 0.65, respectively) and adults without DS (P < 0.001; P < 0.001; R2 = 0.75 and 0.61, respectively). Absolute error of prediction was significantly smaller for VM than VA for sitting, playing app, drawing, sweeping, standing and basketball (P ≤ 0.005), but smaller for VA than VM for walking at 0.8 m·s−1 (P = 0.005). Bland–Altman plots for adults with and without DS indicated narrower limits of agreement for VM than VA (−5.57 to 5.57 and −6.44 to 6.44 mL·kg−1·min−1; −6.21 to 6.17 and −7.75 to 7.74 mL·kg−1·min−1, respectively). Conclusions: Vector magnitude and VA are significant predictors of V̇O2 in adults with and without DS, yet VM more accurately estimated V̇O2 than VA for most tasks. Development of accelerometer‐based prediction of physical activity levels in adults with and without DS may improve by utilising VM counts. [ABSTRACT FROM AUTHOR]

This study examined the associations among cardiovascular comorbidities, symptoms of depression and anxiety, and physical activity in persons with multiple sclerosis. Participants with multiple sclerosis (N = 217) completed demographic, cardiovascular comorbidity, depression, and anxiety self-report measures, and wore an accelerometer for 7 days. We examined the bivariate, non-parametric correlations among the variables and conducted parametric, independent samples t-tests when examining the differences in variables based on cardiovascular comorbidity status. Bivariate correlation analysis indicated that there were statistically significant associations between anxiety scores, but not depression scores, and cardiovascular comorbidities. Physical activity, especially moderate-to-vigorous physical activity (MVPA), was correlated with cardiovascular comorbidities. There were small significant differences based on hyperlipidemia status in anxiety scores (p = 0.015, d = -0.42), MVPA (p < 0.001, d = 0.44), and steps/day (p < 0.001, d = 0.50), and based on hypertension status in anxiety scores (p = 0.010, d = -0.35), depression scores (p = 0.046, d = -0.26), MVPA (p = 0.003, d = 0.41), and steps/day (p < 0.001, d = 0.53). The findings indicate that there are significant associations among cardiovascular comorbidities, symptoms of depression and anxiety, and physical activity in persons with multiple sclerosis. Physical activity, specifically MVPA, may be a target for managing those outcomes in persons with multiple sclerosis. [ABSTRACT FROM AUTHOR]

Objective: This study examined body fatness and its association with cardiorespiratory fitness (CRF) in persons with multiple sclerosis (pwMS) accounting for disability status. Materials and Methods: This study involved a secondary data analysis from a previous study of 62 pwMS. Body fatness was indirect measured as body mass index (BMI), and CRF was measured as peak oxygen consumption from an incremental exercise test with spirometry. Participants were allocated into 3 different groups based on established BMI categories (ie, normal, overweight, and obese), and data were analyzed using SPSS. Results: The average BMI was 27.0 (6.7) kg/m2, and CRF was 19.5 (7.2) mL/kg/min. There was an inverse correlation (pr = ‐.38 [−.57; −.14]; P = .003) between BMI and CRF controlling for age, sex, disease duration, and disability level. ANCOVA with linear contrast analysis revealed a statistical significant reduction in CRF between groups of different BMI categories; normal weight 20.8 (0.85); overweight 19.8 (1.13); and obese 16.9 (1.73) mL/kg/min; F (2, 55) = 3.33, P = .043; η2 = .11. Conclusions: The findings suggest that BMI has a negative impact on CRF in pwMS, with a marked reduction in CRF for those classified as obese compared to those in the normal and overweight category.

Individuals with multiple sclerosis (MS) are more sedentary than the general population, increasing their propensity for reduced functional ability, mobility, and activities of daily living. Self-efficacy has been one of the most consistent determinants of physical activity across populations, including those with MS. However, no studies exist that have attempted to influence self-efficacy in MS patients, in an effort to improve physical activity participation. We conducted a three-month randomised, controlled trial (n=26), contrasting the effects of an efficacy-enhancement exercise condition and a control exercise condition on exercise adherence, well-being, and affective responses to exercise. Analyses indicated that individuals in the efficacy enhancement condition attended more exercise sessions, reported greater levels of well-being and exertion, and felt better following exercise than individuals in the standard care condition. Regardless of treatment condition, individuals with a stronger sense of exercise self-efficacy, who reported more enjoyment following the exercise sessions, demonstrated significantly greater adherence with the exercise program. We believe this to be the first empirical attempt to change physical activity behavior in persons with MS using a well-established theoretical framework to drive the intervention. Continued examination of self-efficacy as a determinant of behavior change in individuals with MS is needed. [ABSTRACT FROM AUTHOR]

The uptake and benefits of the Canadian Physical Activity Guidelines for Adults with Multiple Sclerosis (PAGs) have been validated, but there is limited understanding regarding the knowledge, needs, and preferences of people with multiple sclerosis (MS) for implementing the PAGs outside of clinical research. The authors conducted online, semistructured interviews with 40 persons with MS from across the United States seeking information on awareness of and potential approaches for increasing the uptake of the PAGs. They identified first impressions and potential approaches for increasing the uptake of the PAGs through inductive, semantic thematic analysis. Participants perceived the PAGs as a good introduction for structured exercise but desired more information on how to meet the PAGs. Participants further believed that modifying the PAGs for inclusivity and applying a multifaceted approach for dissemination and implementation may increase uptake of exercise behavior. Physical activity research in MS should include both analyzing the effects of exercise and the unique challenges faced by persons with MS in putting the PAGs into practice. [ABSTRACT FROM AUTHOR]

Three hundred and sixty-three older adults with multiple sclerosis completed a cross-sectional study examining hierarchical correlates of physical activity using a social cognitive theory perspective within a social ecological model (i.e., built environment, social environment, and individual social cognitive theory variables). Hierarchical linear regression analyses were conducted, wherein significant associations were noted for built environment (i.e., land-use mix diversity and aesthetics) and physical activity in Step 1 (R2 =.09). Social and built environment were significant correlates in Step 2 (R2 =.15). Finally in Step 3, individual social cognitive theory variables (i.e., self-efficacy and outcome expectations) were the only significant correlates of total physical activity (R2 =.38). Results were comparable for health-promoting physical activity; however, self-efficacy was the only significant correlate in Step 3 (R2 =.36). This study provides guidance for researchers and practitioners on relevant targets for tailoring interventions for older adults with multiple sclerosis and supports an emphasis on self-efficacy as a primary predictor of health behavior change.

Background Persons with multiple sclerosis ( MS) engage in substantially less overall physical activity than healthy controls, but there is little information on public health rates of physical activity necessary for health benefits. Purpose This study examined the rates of insufficient, moderate, and sufficient physical activity in persons with MS compared with healthy controls. Method Secondary analysis of data from participants with MS ( n = 1521) and healthy controls ( n = 162) who completed the Godin Leisure-Time Exercise Questionnaire ( GLTEQ) as part of a questionnaire battery in 14 previous investigations. Results There were statistically significant differences in overall GLTEQ scores ( F1,1666 = 96.8, P < 0.001, d = 0.83) and rates of physical activity ( χ2 (2, N = 1683) = 94.2, P < 0.001) between MS and control groups. The rates of insufficient, moderate, and sufficient physical activity in the MS group were 58.0%, 15.2%, and 26.8%, respectively. Those with MS were 2.5 times more likely to report insufficient physical activity and 2.3 times less likely to report sufficient physical activity than controls. Conclusion The majority of persons with MS were insufficiently physically active, and this segment represents the largest opportunity for successful behavior change and accumulation of associated health benefits.

Objectives There is increasing recognition that physical activity has beneficial consequences among persons with multiple sclerosis ( MS), but there is concern regarding the current degree of physical inactivity in this population because of limitations with previous research and increased recognition of health behaviors in MS. This study compared physical activity levels between large samples of persons with mild MS and matched controls using validated measures of physical activity. Materials and methods The sample included 77 cases of MS and 77 controls matched on age, height, weight, and gender. Physical activity was assessed using five measures, namely the Godin Leisure-Time Exercise Questionnaire ( GLTEQ), International Physical Activity Questionnaire ( IPAQ), and activity counts per day, step counts per day, and time spent in moderate-to-vigorous physical activity ( MVPA) per day by accelerometry. Results There were statistically significant differences between groups in accelerometer activity counts ( t = −3.87, P = 0.0001), accelerometer step counts ( t = −4.29, P = 0.0001), time spent in MVPA ( t = −2.39, P = 0.01), GLTEQ scores ( t = −3.83, P = 0.0001), and IPAQ scores ( t = −3.42, P = 0.0001). The average effect size across all five measures was d = −0.59 and indicated that persons with MS overall were moderately less physically active than the matched controls. Conclusions The primary finding was a moderate reduction in physical activity among those with MS, but the magnitude was substantially smaller than reported in a published meta-analysis. Importantly, the degree of physical inactivity can likely be overcome through the delivery of behavioral interventions for increasing physical activity and this should translate into meaningful consequences for persons with MS.

Motl RW, Goldman M. Physical inactivity, neurological disability, and cardiorespiratory fitness in multiple sclerosis. Acta Neurol Scand: 2011: 123: 98-104. © 2010 John Wiley & Sons A/S. We examined the associations among physical activity, neurological disability, and cardiorespiratory fitness in two studies of individuals with multiple sclerosis (MS). Study 1 included 25 women with relapsing-remitting MS (RRMS) who undertook an incremental exercise test for measuring peak oxygen (V̄O) consumption, wore an accelerometer during a 7-day period, and completed the Godin Leisure-Time Exercise Questionnaire (GLTEQ). Study 2 was a follow-up of Study 1 and included 24 women with RRMS who completed the self-reported Expanded Disability Status Scale (EDSS), undertook an incremental exercise test, wore an accelerometer during a 7-day period, and completed the GLTEQ. Study 1 indicated that V̄O was significantly correlated with accelerometer counts (pr = 0.69) and GLTEQ scores (pr = 0.63) even after controlling for age and MS duration. Study 2 indicated that V̄O was significantly correlated with accelerometer counts (pr = 0.50), GLTEQ scores (pr = 0.59), and EDSS scores (pr = −0.43) even after controlling for age and MS duration; there was a moderate partial correlation between accelerometer counts and EDSS scores (pr = −0.43). Multiple linear regression analysis indicated that both accelerometer counts (β = 0.32) and EDSS scores (β = −0.40) had statistically significant associations with V̄O. The findings indicate that physical inactivity and neurological disability might represent independent risk factors for reduced levels of cardiorespiratory fitness in this population.

Using meta-analytic procedures, this study examined the overall effect of exercise training interventions on quality of life (QOL) among individuals with multiple sclerosis (MS). We searched MEDLINE, PSYCHINFO and CURRENT CONTENTS PLUS for the period of 1960 to November 2006 using the key words exercise, physical activity and physical fitness in conjunction with QOL and MS. We further conducted a manual search of bibliographies of the retrieved papers as well as literature reviews and contacted study authors about additional studies. Twenty-five journal articles were located and reviewed, and only 13 provided enough data to compute effect sizes expressed as Cohen's d. One hundred and nine effect sizes were retrieved from the 13 studies with 484 MS participants and yielded a weighted mean effect size of g = 0.23 (95% CI = 0.15, 0.31). There were larger effects associated with MS-specific measures of QOL and fatigue as an index of QOL. The nature of the exercise stimulus further influenced the magnitude of the mean effect size. The cumulative evidence supports that exercise training is associated with a small improvement in QOL among individuals with MS. [ABSTRACT FROM AUTHOR]

Background: We reported that a social cognitive theory-based (SCT), Internet-delivered behavioral intervention increased device-measured minutes/day of moderate-to-vigorous physical activity (MVPA) over a 6-month period among persons with multiple sclerosis (MS). This paper examined the pattern and predictors of heterogeneity in change for MVPA. Based on previous research, we hypothesized that mild MS disability, fewer MS symptoms, lower baseline MVPA, and positive SCT characteristics (e.g., high exercise self-efficacy) would be associated with greater change in MVPA. Method: Persons with MS (N = 318) were randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions that were administered via Internet websites and supported with behavioral coaching. Demographic, clinical, symptom, behavioral, and SCT data were from before the 6-month period of delivering the conditions, and MVPA data were from before and after the 6-month period. We examined heterogeneity based on waterfall plots, box plots, and the Levene statistic. We identified predictors of MVPA change using bivariate correlation and multiple, linear regression analyses per condition. Results: The Levene statistic indicated statistically significant heterogeneity of variances for MVPA change between conditions (p =.003), and the waterfall plots and box plots indicated greater heterogeneity in MVPA change for the behavioral intervention. MVPA change score was correlated with baseline MVPA (r = −.33 and r = −.34, p =.0004 and p =.0001) in both conditions and walking impairment (r = −.188, p =.047) and race (r =.233, p =.014) in the behavioral intervention condition. The regression analysis indicated that baseline MVPA (Standardized B = −.449, p =.000002), self-reported walking impairment (Standardized B = −.310, p =.0008), and race (Standardized B =.215, p =.012) explained 25.6% of variance in MVPA change for the behavioral intervention condition. Conclusion: We provide evidence for walking impairment, baseline MVPA, and race as predictors of the heterogeneity in the pattern of MVPA change with a behavioral intervention.

Aims: To investigate the prevalence of physical inactivity in older adults living in nursing homes and explore the determinants of physical inactivity by using the Capability, Opportunity, Motivation–Behaviour model. Design: A multisite, cross‐sectional study was performed by convenience sampling and questionnaire survey. Methods: A total of 390 nursing home residents were recruited from three nursing homes in Southern China from May 2022 to April 2023. The participants completed a self‐designed general information questionnaire, Physical Activity Scale for the Elderly, Self‐Efficacy for Exercise Scale, Exercise Benefits Scale, Patient Health Questionnaire‐9 and the Short Physical Performance Battery test. Descriptive statistics, univariate analysis, Spearman correlation analysis, and ordinal logistic regression were applied for data analysis. Results: The prevalence of physical inactivity among the nursing home residents reached 88.46%. Ordinal logistic regression results showed that exercise self‐efficacy, perceived exercise benefits, physical function, availability of physical activity instruction, having depression, number of chronic diseases and living with spouse were the main influencing determinants of physical inactivity and explained 63.7% of the variance. Conclusions: Physical inactivity was considerable in nursing home residents in China and influenced by complex factors. Tailored measures should be designed and implemented based on these factors to enhance physical activity while considering the uniqueness of Chinese culture. Implications for the profession and patient care: Healthcare professionals should enhance physical activity of residents by increasing benefits understanding, boosting self‐efficacy, improving physical function, alleviating depression and integrating personalized physical activity guidance into routine care services. And more attention should be paid to the residents who had more chronic diseases or did not live with spouse. Impact: Physical inactivity is a significant problem in nursing home residents. Understanding physical inactivity and its determinants enables the development of tailored interventions to enhance their physical activity level. Reporting method: This study was reported conforming to the STROBE statement. Patients or Public Contribution: Nursing home residents who met the inclusion criteria were recruited.

Objective: The study aimed to 1) examine relationships between contexts of PA, personality traits, and high school sports participation (sports) and 2) determine significant PA correlates in a college population. Participants: 237 undergraduates at a university in the United States between September 2020 and May 2021 participated. Methods: Participants completed a survey evaluating PA, personality traits, sports, and demographic variables. Pearson partial correlations assessed correlations between different PA domains, personality traits, and sports. Conscientiousness was positively associated with all PA measures (r =.14-.30), except for active transport PA. Sports were related to vigorous and leisure PA. Conscientiousness is related to PA measures and is a significant PA correlate. However, more research is necessary to understand if leisure time PA can enhance Conscientiousness.

Background/Objectives: Patients with COPD have altered self-esteem, and good self-esteem promotes personal, health, and social success. Improving self-esteem could be a method for encouraging the maintenance of physical activity. Only one study has evaluated the effects of pulmonary rehabilitation (PR) on self-esteem in moderate COPD patients. The objective was to assess the evolution of self-esteem in COPD patients of all stages of severity during PR. Methods: COPD patients undergoing PR were included in this prospective observational study. Patients were evaluated before and after the 4-week PR program. The objectives were to (1) assess the evolution of self-esteem using the Physical Self Inventory-6 questionnaire (PSI-6), (2) assess the evolution in each sub-score of PSI-6, (3) examine the correlations between the evolution of self-esteem and the evolution of parameters usually used during PR, and (4) determine an MID for self-esteem. Results: In total, 76 patients were included. We found that there was a significant increase in the total score in PSI-6 (9.29, p < 0.001), CI 95% [6.74; 11.83], and in the sub-scores of PSI-6. The evolution of the PSI-6 score was moderately correlated with changes in exercise capacity using STST1 (r = 0.352, p = 0.002) and quality of life (r = −0.361, p = 0.001) and weakly correlated to changes in dyspnea (r = −0.245, p = 0.03), anxiety (r = −0.248, p = 0.03), and depression (r = −0.290, p = 0.01). Using a distribution-based analysis, we found an MID between 5.2 and 5.6. Conclusions: We showed a significant increase in global score and in each sub-score of self-esteem using PSI-6 in COPD patients undergoing a PR program. We propose an MID of 5.6.

This study aims to demonstrate the effect of a transtheoretical model (TTM)-based physical activity program on the exercise behavior of adolescents using WhatsApp. The study was conducted with high school students (N = 185) in a pre-/posttest, quasi-experimental design. TTM-based text messages were sent to the intervention group (n = 95) over WhatsApp every day for 8 weeks. The intervention group demonstrated more statistically significant progression in the exercising stages of change compared to the control group (n = 90) (χ2 = 20.10; p =.00). It was also found that this group had a higher exercising self-efficacy score (t = 2.647; p =.009) and a higher physical activity total metabolic equivalent of task score (Z = −3.521; p =.000). There was no significant difference in BMI and perception of pros and cons (p >.05). The program was found to be effective in terms of recording progress in the exercising stages of change, increasing exercising self-efficacy, and maintaining a physical activity program.

BACKGROUND: Fatigue is the most prevalent symptom among people with multiple sclerosis (PwMS). Although exercise effectively reduces fatigue, the relationship between daily physical activity and fatigue has only recently been demonstrated. OBJECTIVE: The aim of this study was to evaluate the prevalence of fatigue and to understand the relationship with several variables in French PwMS. METHODS: Data were collected from 191 PwMS using Modified Fatigue Impact Scale (MFIS) and Fatigue Severity Scale (FSS) for fatigue, and the Godin Leisure-Time Exercise Questionnaire (GLTEQ) for physical activity. RESULTS: 110 PwMS (57%), 35 PwMS (18%) and 46 PwMS (24%) were considered as fatigued, non-fatigued and in the grey zone, respectively. Greater physical activity was observed in non-fatigued PwMS (20.2±19.8) compared to fatigued PwMS (12.5±14.1). FSS and MFIS scores were associated with physical activity (r = –0.28 and r = –0.25, respectively, p < 0.05). Using multivariate analysis, disability, physical activity and being unemployed explained 21% of the variance of the MFIS. CONCLUSIONS: The present study confirms that physical activity and fatigue are associated. Disability and unemployment status should also to be consider when assessing fatigue. Activity-oriented health policies should be redesigned to improve fatigue among PwMS. [ABSTRACT FROM AUTHOR]

The present study examined the relationship between the worsening of symptoms across a 3-5-year period of time and self-reported physical activity in a sample of 51 individuals with multiple sclerosis (MS). Of the 51 participants, 35 reported a worsening of symptoms over the 3-5-year period of time. The worsening of symptoms was associated with significantly and moderately lower levels of selfreported physical activity independent of depression and EDSS scores and MS-disease course (P=0.04). This study provides novel evidence that a worsening of symptoms is associated with lower levels of physical activity in individuals with MS. [ABSTRACT FROM AUTHOR]

Background/Objectives: Individuals with subjective cognitive decline (SCD) have an increased risk of developing dementia, while non-pharmacological multicomponent lifestyle interventions are recommended for prevention/management. The Greek Interventional Geriatric Initiative to Prevent Cognitive Impairment and Disability (GINGER) is such a multicomponent approach, encompassing simultaneous interventions (cognitive training, depression and sleep management, etc.). Exercise/Physical activity (PA) is suggested as one such intervention. This study (i) presents the exercise protocol developed for GINGER and (ii) explores its feasibility (acceptability, applicability, adherence, users' satisfaction and reliability). Methods: Exercise/PA protocol development, targeting SCD individuals aged > 55 years, utilized relevant guidelines/literature followed by focus group involving exercise specialists. Data were synthesized through consensus to design optimal exercise interventions prescribed on participant's physical capacity (heart rate, exertion, etc.), comprising 6-month combined aerobic, strengthening, balance and dual-task exercises, delivered 3 times/weekly in two group-based supervised sessions (in-person and online) and one home-based session. Physical outcomes include balance, aerobic capacity [2-Minute Walk Test (2 MWT), IPAQ-7], strength [Hand Grip Strength (HGS), Sit-to-Stand], fear of falling. Eligibility for entering intervention is low IPAQ-7, 2 MWT or HGS scoring. Feasibility was explored with adherence (exercise diaries and Exercise Adherence Rating Scale) and satisfaction (Patient Satisfaction Questionnaire) Results: Intervention was easily delivered with good reliability across testers' assessments on 13 SCD participants (ICCs = 0.62–0.99), and improved physical outcomes, whereas users' adherence and satisfaction scored highly. Conclusions: The exercise protocol for SCD was feasible, acceptable, applicable, reliable, demonstrating adherence and satisfaction, while improving physical parameters. It is thus integrated in the GINGER study, where multiple simultaneous interventions will take place to prevent/enhance cognitive function. [ABSTRACT FROM AUTHOR]

Objective: To explore the relationship between mental health and physical activity (PA) in middle school students, and examining the roles of negative emotions and self-efficacy in the relationship. Methods: Data from 1,134 Chinese middle school students (50.2% females, 49.8% males; M age = 15.18, SDage = 2.00) were collected using the Physical Activity Rating Scale (PARS-3), Positive and Negative Affect Scale (PANAS), General Self-Efficacy Scale (GSES), and Middle School Student Mental Health Scale (MSSMHS). Results: (1) There is a significant positive correlation between PA and mental health (r = 0.16, p < 0.01), and the direct path of PA on mental health is significant (t = 2.101, p < 0.01). (2) PA negatively predicts negative emotions (r = −0.12, p < 0.01), and is significantly positively correlated with self-efficacy (r = 0.24, p < 0.01). Negative emotions negatively predict self-efficacy (r = −0.23, p < 0.01) and mental health (r = −0.67, p < 0.01). Self-efficacy positively predicts mental health (r = 0.30, p < 0.01). (3) Negative emotions and self-efficacy play a significant mediating role between PA and mental health. The mediating effect includes three paths: PA → negative emotion → mental health (effect value: 0.130); PA → self-efficacy → mental health (effect size: 0.052); PA → negative emotions → self-efficacy → mental health (effect size: 0.006). Conclusion: PA among middle school students can indirectly affect mental health through negative emotions and self-efficacy. Middle school students should be encouraged to participate in PA to reduce their negative emotions and increase their self-efficacy, thus improving their mental health. [ABSTRACT FROM AUTHOR]

Physical activity identity represents an important determinant of sustained physical activity behavior. The purpose of this investigation was to examine whether intention, behavioral regulation, and moderate-to-vigorous physical activity (MVPA) behavior explain significant variation in physical activity identity across time. Using a repeated measures observational design, lower-active adults new or returning to physical activity participation (N = 66) completed measures of study variables every three weeks over the course of a nine-week period (four assessments total). Based on the results of mixed-effects regression modelling, there was a small, non-significant increase in physical activity identity across time (b = 0.07, p = 0.13). Intention, MVPA, and behavioral regulation mostly had significant (ps < 0.05) bivariate correlations with physical activity identity at the same time point of assessment. Behavioral regulation explained significant variation in physical activity identity across time (b = 0.26, p < 0.0001), but intention and MVPA were non-significant (ps > 0.05) after including a random intercept and controlling for behavioral regulation. Identity was resistant to change among new physical activity initiates in this study and longer time frames of assessment are needed (e.g., six months). Behavioral regulation should be examined as a determinant of physical activity identity in future investigations. [ABSTRACT FROM AUTHOR]

As Attention-Deficit/Hyperactivity Disorder (ADHD) may have an unknown influence on the self-reports of physical activity of adults with ADHD and there is a need for high quality self-report assessments of this kind, we examined the test-retest reliability and construct validity of the Godin Leisure-Time Exercise Questionnaire–Health Contributions Score (GLTEQ–HCS) in its use with 35 adults with Attention-Deficit/Hyperactivity Disorder (ADHD) (26 females, 9 males; M age = 28.7, SD = 6.3 years). Participants completed the GLTEQ twice and wore an ActiGraph GT9X–accelerometer for seven-days. An intraclass correlation coefficient (ICC) determined test-retest reliability, and we determined construct validity based on correlations between the GLTEQ–HCS and minutes/day of sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), as well as differences in SB, LPA, and MVPA among the three GLTEQ–HCS subgroups. The GLTEQ-HCS had excellent test-retest reliability [ICC = 0.98, 0.95 to 0.99], and it was positively correlated with MVPA (r = 0.47, p =.006; r s = 0.52, p =.002). There was a significant and large difference in minutes/day of device-measured MVPA between the three GLTEQ–HCS groups [ F (2,32) = 7.30, p =.003, η 2 = 0.33]. These results provide psychometric support for using the GLTEQ-HCS with adults who have been diagnosed with ADHD. [ABSTRACT FROM AUTHOR]

Older adults in assisted living facilities (ALF) are at risk for low physical activity (PA) and high sedentary behavior (SB), both of which place them at risk for negative health outcomes. The purpose of this scoping review was to synthesize evidence describing the volume of device-measured PA/SB, factors associated with PA/SB, and interventions designed to change PA/SB in older adults living in ALF. Twenty articles representing 15 unique studies were identified from eight electronic databases and grey literature. Residents in ALF spent 96–201 min/day in light PA (n = 2 studies), 1–9.74 min/day in moderate to vigorous PA (n = 2 studies), and 8.5–11.01 hr/day of SB during waking hours (n = 3 studies). Factors associated with PA included 16 personal factors (n = 6 articles), one social factor (n = 2 articles), and two environmental factors (n = 2 articles). Factors associated with SB included 14 personal factors (n = 4 articles) and one social factor (n = 1 article). No intervention successfully changed PA/SB. [ABSTRACT FROM AUTHOR]

Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by demyelination in the central nervous system (CNS), affecting individuals globally. The pathological mechanisms underlying MS remain unclear, but current evidence suggests that inflammation and immune dysfunction play a critical role in the pathogenesis of MS disease. Adipose tissue (AT) is a dynamic multifunctional organ involved in various immune diseases, including MS, due to its endocrine function and the secretion of adipokines, which can influence inflammation and immune responses. Physical activity represents an efficacious non-pharmacological strategy for the management of a spectrum of conditions that not only improves inflammatory and immune functions but also directly affects the status and function of AT. Additionally, the exploration of nutritional supplementation represents an important field of MS research aimed at enhancing clinical symptoms and is closely tied to the regulation of metabolic responses, including adipokine secretion. This review, therefore, aims to elucidate the intricate relationship between lifestyle and MS by providing an overview of the latest published data about the involvement of AT and the main adipokines, such as adiponectin, leptin, and tumor necrosis factor α (TNFα) in the pathogenesis of MS. Furthermore, we explore whether physical activity and dietary management could serve as useful strategies to improve the quality of life of MS patients. [ABSTRACT FROM AUTHOR]

Objective: To examine the effects of instructor-led exercise on depression symptoms in adults with multiple sclerosis, with a focus on moderating factors to treatment response. Data sources: Cochrane Library, Embase, PEDro, PsycINFO and PubMed databases were searched until 21 April 2024. Review methods: The reporting quality of included studies assessed (PEDro and TESTEX scales). Hedges' g effect sizes were calculated and pooled using random and mixed-effects modelling. Results: Twenty-two independent studies (k), representing 785 participants with relapsing remitting or progressive MS, were included. Individual studies varied in their reporting quality (PEDro range: 3–8) and did not routinely detail exercise parameters (TESTEX range: 5–13). Nonetheless, exercise reduced core symptoms of depression (g w =.52, CI:.30–.73, P <.01). Treatment effects were, however, not maintained once training had ceased (g w = −.53, CI: −.80 to.24, P ≤.01, k = 5). Both aerobic and non-aerobic exercise groups experienced a significant (P <.01) reduction in depression scores. Larger gains were noted by those with better ambulation at baseline (P =.03). Conclusion: Regular exercise can help to stabilise mood for people living with multiple sclerosis, regardless of session frequency or duration. Treatment efficacy could be maximised by addressing potential barriers for those with limited mobility, including exercise type, delivery and intensity.

The Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) is not available to Portuguese-Brazil. This study translates, cross-culturally adapts, and validates the PASIPD for Brazilian individuals with Parkinson's disease. The translation process followed guidelines: initial translation, synthesis, back translation, expert committee, and pretest. The validation and reliability processes were conducted with 40 individuals (15 men and 25 women) with Parkinson's disease. Concurrent validity was evaluated between PASIPD to Brazilian Portuguese, International Physical Activity Questionnaire, and Human Activity Profile. PASIPD to Brazilian Portuguese was found to be moderately correlated with International Physical Activity Questionnaire (r =.474, p <.05); however, there was no correlation with Human Activity Profile (r =.271, p <.05). We used the intrarater reliability with intraclass correlation coefficient and test–retest. Intrarater reliability was high (intraclass correlation coefficient =.80). Internal consistency was considered adequate by Cronbach's alpha (α =.70). PASIPD to Brazilian Portuguese is a valid and reliable instrument for evaluating physical activity levels in Brazilian individuals with Parkinson's disease. [ABSTRACT FROM AUTHOR]

This brief research note examined the reliability of scores from an accelerometer as measures of sedentary and physical activity behaviors in persons with multiple sclerosis (MS). The analysis was performed on a combined data set from 2 previous longitudinal investigations of physical activity in MS. We focused on the number of days required to reliably estimate sedentary behavior, based on time spent in sedentary behavior per day and number of sedentary breaks, number of long sedentary bouts, and average length of sedentary bouts per day. We further examined the number of days required to reliably estimate physical activity behavior, based on time spent in light and moderate-to-vigorous physical activity and average length of activity bouts per day. Between 4-6 days of monitoring and 3-7 days of monitoring were necessary for good reliability of scores from all sedentary outcomes and physical activity outcomes, respectively. These results should guide research and practice examining sedentary and physical activity behaviors using accelerometry in persons with MS. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of the online version of the Chronic Disease Self-Management Program (CDSMP) on physical activity and depressive symptoms in individuals with non-communicable diseases (NCDs) in Mexico and Peru during the COVID-19 pandemic. Materials and Methods: Quasi-experimental study with a non-probability sample of 114 people with NCDs, recruited by invitation in Mexico and by convenience in Peru. The participants were assigned to intervention (n = 85) and control (n = 29) groups. The Personal Health Questionnaire (PHQ-8) and the Physical Activity Scale were used to assess the outcomes. Measurements were taken before and after the intervention. The CDSMP comprises six sessions that take place once per week and last 2.5 h each. Results: The intervention group showed a significant reduction in depressive symptoms and an increase in physical activity (PA) at the end of the program. In contrast, the control group showed no significant improvement in depression and presented a significant decrease in PA. [ABSTRACT FROM AUTHOR]

Physical activity is the whole of daily living activities, recreational activities, exercises and sports activities that occur with energy consumption using skeletal muscles and joints. The aim of this study was to investigate the effect of regular Physical Activity Programs (PAP) on the general well-being and happiness levels of women who started doing sports for the first time within the scope of Kocaeli Metropolitan Municipality's Mother City Project. Thirty-five women (age: 42.91±7.269) participated voluntarily in this study. Participants took part in Pilates, Zumba and step aerobics sessions for one hour, three days a week (Monday, Wednesday and Friday). A PAP, consisting of an 8-kilometer walking program, was applied on Tuesdays, Thursdays and Saturdays for 12 weeks. The Well-Being Scale and Happiness Scale were administered to the participants before and after the PAP. The SPSS 25 software package was used for data analysis. A dependent two-sample t-test was used to compare pretest-posttest data. Descriptive statistics values were also included. According to the analysis results, a statistically significant difference was detected between the pretest and posttest scores of the total Well-Being Scale and its sub-dimensions: Positive Emotions, Positive Relationships, Happiness, Engagement, Meaning, Accomplishment and Health (p<0.05). No statistically significant difference was detected in the other sub-dimensions: Negative Emotions and Loneliness (p>0.05). Additionally, a statistically significant difference was found in the Happiness Scale in the pretest and posttest comparison (p<0.05). As a result, it has been observed that regular physical activity programs positively affect the general well-being and happiness levels of housewives. In this context, it is recommended that housewives participate in more physical activities. [ABSTRACT FROM AUTHOR]

Our study investigated whether changes in physical activity due to COVID-19 mediate the association between quarantine or hospitalization due to COVID-19 and COVID-19 life impact score. A total of 154 participants (0.23%) were quarantined or hospitalized due to COVID-19. There were mediating effects of changes in physical activity due to COVID-19 (β = −1.63, 95% confidence interval = −0.77 to −2.42). This study suggests that measures to minimize lifestyle changes during the pandemic are required to reduce negative consequences. [ABSTRACT FROM AUTHOR]

Research has identified a positive relationship between physical activity and neuropsychological functioning across the lifespan. The present study further examined the relationship between physical activity, depression, anxiety, and cognitive functioning in community-dwelling older adults (ages 65–96) who completed an outpatient neuropsychological evaluation (N = 526). Psychometrically sound and validated measures were used to assess depression, anxiety, and cognitive functioning. Analyses of covariance (ANCOVA) were conducted to examine differences between individuals who reported regularly engaging in physical activity and those who did not, after adjusting for demographic variables (age, education, and gender). Results indicated that physical activity was associated with better scores on measures of depression, anxiety, and cognitive functioning. Effect sizes for total scores on all measures were large, but there was a sizeable range of effect sizes (from small to large) for various cognitive domains. Smallest effect sizes were observed for subtests measuring language skills and visuospatial abilities, whereas largest effect sizes were seen in processing speed and memory. Results suggest that engaging in physical activity may be a beneficial non-pharmacological intervention for older adults. These findings underscore the importance of integrating physical activity programs in community and healthcare settings to foster mental and cognitive health in older populations.

Objectives: This systematic review and meta-analysis examines the efficacy of physical activity interventions in the reduction of antisocial behavior in children and adults. Several possible moderators, including study design, sample characteristics (age, proportion male, and sample type), control group, and outcome characteristics (type of activity, duration, frequency), were also investigated. Methods: A literature search was performed in the following databases: PubMed, Ebsco/SportDiscus, Ebsco/APA PsycINFO, Ebsco/ERIC, Ebsco/Criminal Justice Abstracts, Embase.com, and Clarivate Analytics/Web of Science Core Collection from inception to June 2021. Studies were eligible if they reviewed the effect of chronic physical activity interventions on antisocial behavior compared to wait-list, no-exercise, or attention control samples. The following studies were excluded: animal studies, studies reporting on acute exercise, studies including yoga or mindfulness as the sole measure of physical activity, and studies including substance (ab)use and/or smoking as the only outcome measure. A random effects model was used to calculate pooled effect sizes. The risk of bias was assessed using the Cochrane risk-of-bias tool (version 2). Results: The search yielded 29 studies, of which 20 were included in the meta-analysis. Results indicate a significant small-to-medium effect (g = − 0.26) with a 95% confidence interval ranging from − 0.48 to − 0.04 in favor of physical activity interventions. Significant moderators included type of control group, type of physical activity, and type of antisocial behavior, with larger effect sizes for comparisons with inactive control groups (g = − 0.31), interventions containing walking, jogging, or running as the main type of physical activity (g = − 0.87), and anger/hostility as an antisocial outcome measure (g = − 0.42). Conclusions: Physical activity interventions may be a promising way to reduce antisocial behavior in children and adults. However, due to the overall high risk of bias in the included studies, more sound evaluation research is needed to better understand the functioning and to improve the possible implementation of physical activity interventions.

The purpose of this study was to examine the inclusiveness of visually impaired youths' experiences in integrated physical education. An experiential qualitative research approach was utilized, and 22 visually impaired youth (age 12–17 years) acted as participants. Data sources included one-on-one Zoom interviews, written responses to long-answer prompts, and reflexive interview notes. Data were analyzed using a reflexive thematic analysis approach, and three themes were constructed: (a) I'm not there, so how could I: The absent person; (b) I can't see, so I can't do it: The incapable person; and (c) It'd be nice to feel like everyone else: The "normal" person. Participants described that feelings of inclusion were unavailable to them and that feeling, and being viewed as, absent, incapable, and (not) "normal" highlighted this unavailability.

An estimated 2.5 million people worldwide are living with multiple sclerosis (MS), and this disease may be increasing in prevalence. MS is a disease of the central nervous system that is associated with heterogeneous symptoms and functional consequences, and the current first-line disease-modifying therapies often become ineffective later in the disease. There is increasing evidence for the benefits of physical activity (PA) in people with MS, but this population is generally physically inactive and sedentary. We proposed 10 research questions to guide future research on PA and MS: (1) Is PA an MS disease-modifying behavior? (2) What are the benefits of PA among people with MS? (3) What is the optimal PA prescription for people with MS? (4) What are the safety issues with PA in people with MS? (5) What characteristics of people with MS modify the benefits of PA? (6) What variables explain participation in PA among people with MS? (7) What are effective behavioral interventions for PA change in people with MS? (8) How do we translate PA research into clinical MS practice? (9) What is the role of sedentary behavior in people with MS? And (10) what is the optimal measurement of PA in people with MS? These questions are critical for informing our understanding of the short- and long-term consequences of PA in MS as well as for identifying approaches for promoting and sustaining PA in MS. Addressing these questions may greatly improve the lives of people with this chronic disease. [ABSTRACT FROM PUBLISHER]

This study examined the impact of group composition of a 6-week group-based employee Fitbit intervention on daily physical activity steps. Group composition comprised heterogenous and homogeneous groupings based on variations in baseline high, medium, and low steppers. The intervention included weekly step leaderboard information, motivational and informative messages, and the ability to participate in group step challenges. Repeated measures analysis of variance (ANOVA) examined differences in change of steps across time, step-level groups (low, medium, and high), and group composition (low/high, similar, and mixed), and replicated with a subgroup of participants who participated in group step challenges. While group and step level did not emerge as significant interactions in the overall sample, when focused within the group step challenge subsample, relationships among time, the group composition, and participant step-level categories emerged. Overall, the greatest increases in steps occurred at the mid-point time period, among lower steppers, and within the low/high comparison group. This study provides evidence of the importance of group composition in physical activity interventions as well as the fidelity of intervention design in facilitating group comparisons.

Background: Major depressive disorder (MDD) is prevalent, yet sub-optimally treated among persons with multiple sclerosis (MS). We propose that exercise training may be a promising approach for treating depression in persons with MS who have MDD. Our primary hypothesis predicts a reduction in depression severity immediately after an exercise training intervention compared with minimal change in an attention control condition, and the reduction will be maintained during a follow-up period. Methods: This study involves a parallel-group, assessor-blinded RCT that examines the effect of a 4-month home-based exercise training intervention on depression severity in a sample of persons with MS who have MDD based on the MINI International Neuropsychiatric Interview. The primary outcomes of depression severity are the Patient Health Questionnaire-9 and Hamilton Depression Rating Scale. Participants (N = 146) will be recruited from within 200 miles of the University of Illinois at Chicago and randomized (1:1) into either a home-based exercise training condition or control condition with concealed allocation. The exercise training and social-contact, attention control (i.e., stretching) conditions will be delivered remotely over a 4-month period and supported through eight, 1:1 Zoom-based behavioral coaching sessions guided by social-cognitive theory and conducted by persons who are uninvolved in screening, recruitment, random assignment, and outcome assessment. We will collect outcome data at 0, 4 and 8 months using treatment-blinded assessors, and data analyses will involve intent-to-treat principles. Discussion: If successful, the proposed study will provide the first Class I evidence supporting a home-based exercise training program for treating MDD in persons with MS. This is critical as exercise training would likely have positive secondary effects on symptoms, cognition, and quality of life, and provide a powerful, behavioral approach for managing the many negative outcomes of MDD in MS. The program in the proposed research is accessible and scalable for broad treatment of depression in MS, and provides the potential for integration in the clinical management of MS. Trial registration: The trial was registered on September 10, 2021 at clinicaltrials.gov with the identifier NCT05051618. The registration occurred before we initiated recruitment on June 2, 2023 [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was to evaluate the effect of motivational interviewing based on the trans‐theoretical model promoting physical activity in older adults. Methods: A randomized controlled trial study was conducted with 117 older adults (intervention group: 58, and control group: 59) between April and November 2019. The data were collected via a questionnaire, trans‐theoretical model scales, the Physical Activity Scale for the Elderly, the Katz Activities of Daily Living scale and a pedometer. The 24‐week intervention consisted of regular motivational interviewing. The control group received usual care at the family health centre. Results: Following the intervention, the Intervention Group showed significant improvements Exercise Processes of Change Scale, Exercise Self‐Efficacy Scale and Perceived Benefits of the Decisional Balance Scale for Exercise. There was a significant difference between the groups in terms of stages of change. In the Intervention Group, 81.5% were in the contemplation stage in the pre‐test, while in the post‐test, 70.4% had transitioned to the action stage. In contrast, in the control group, 62.5% were in the contemplation stage initially, but in the post‐test, only 9.3% had reached the action stage. The mean number of step counts increased significantly in favour of the Intervention Group, as did the Physical Activity Scale for the Elderly total score. Conclusion: The trial indicated that after the trans‐theoretical model‐based motivational interviewing, the stages of change among the older adults improved, as did their exercise behaviours. It is recommended that the trans‐theoretical model and motivational interviewing be used by nurses to improve healthy lifestyle stage behaviours in older adults. Summary statement: What is already known about this topic? Physical immobility ranks fourth among the leading risk factors for mortality globally.Older adults constitute the age group which leads the most sedentary life in society and is most affected by physical inactivity.In Turkey, one out of every two people undertakes insufficient physical activity, and this rate increases with advancing age. What this paper adds? Nurse‐led motivational interviewing based on the trans‐theoretical model was effective in increasing the physical activity levels of the older adults. The implications of this paper: It is recommended that the trans‐theoretical model and motivational interviewing should be used by nurses to improve healthy lifestyle behaviours in older adults.It is recommended that studies be conducted to assess the effectiveness of interventions aimed at promoting physical activity in older adults via both qualitative and quantitative methods.

Background: The proportion of the population aged 65 years or older is increasing. Typically, physical activity and health decline with age, which is why action to promote active ageing is a major public health priority, particularly due to health inequalities in older adults. The aim of this study is to assess the effectiveness and cost-effectiveness of the Walk with Me peer-led walking intervention for older adults. Methods: This study is a two-arm, assessor-blind, randomised controlled trial. The intervention is a 12-week peer-led walking intervention based on social cognitive theory. Participants in the control group will receive information on active ageing and healthy nutrition. The study will target 348 community-dwelling older adults, aged 60 years or over living in areas of socio-economic disadvantage communities. Trained peer mentors will deliver the intervention. The primary outcome will be a mean between-group change in moderate-to-vigorous physical activity at 12 months from baseline, measured using an Actigraph accelerometer. Secondary outcomes will include quality of life, mental wellbeing, blood pressure, BMI and waist circumference. An embedded process evaluation will involve focus groups and participant diaries. Discussion: Evidence-based, cost-effective interventions to promote physical activity in older adults living in socio-economically disadvantaged communities are needed to address health inequalities.

Background and Aims: Scientific research continues to advance and improve the medical management of type 2 diabetes. However, the importance of lifestyle management remains invaluable in treatment and tertiary prevention of this disease. Day‐to‐day sedentariness is the fourth most important risk factor for mortality in France. Numerous studies have demonstrated that physical activity is beneficial to people with type 2 diabetes and various recommendations have been made to encourage it. However, it is universally agreed that interventions that promote physical activity, while they may enhance its practice in the short term, do not impact on it over longer periods. It therefore seems essential to focus interventions on an individual's capacity to persist with physical activity in the long term. By looking at the literature, the aim of this review is to synthesize group and supervised physical activity interventions for people with type 2 diabetes using variables based on the following levers: motivation and self‐efficacy. Methods: The PRISMA (Preferred Reporting Items for Systematic reviews and Meta‐Analyses) methodology examined studies in English or French that are registered in the PubMed, PsycINFO, and SportDiscus databases and were published between 2005 and 2023, according to the following keywords: Motivation OR self‐efficacy AND physical activity AND type 2 diabetes AND intervention. Results and Conclusion: Seven studies out of 1207 were included. Despite the pertinence of the concepts of motivation and self‐efficacy and their complementarity in physical activity management programs, few studies have yet proposed a combined intervention for people with type 2 diabetes.

BACKGROUND: Physical activity (PA) is a promising intervention for disease modification and symptom management in multiple sclerosis (MS); however, there is a lack of research focusing on PA behavior change interventions for persons newly diagnosed with MS. Such PA behavior change interventions should be developed based on a strong empirical foundation of understanding the behavior and its determinants (ie, what to target for changes to occur). To that end, this qualitative study examined factors explaining PA in persons newly diagnosed with MS and identified potential targets for future behavior change intervention development based on the Capability-Opportunity-Motivation-Behavior (COM-B) model. METHODS: Twenty individuals diagnosed with MS within the past 2 years underwent one-on-one semistructured interviews using questions developed based on the COM-B model. Data were analyzed using reflective thematic analysis, and the identified themes were then mapped with the COM-B model. RESULTS: Factors explaining PA in the study sample were identified across the COM-B components. The typical factors include knowledge and skills to sufficiently engage in PA with appropriate approaches, ability to adapt and navigate through new environmental and social difficulties after diagnosis, and motivation resulting from a combination of factors, such as outcome expectation, belief of capabilities, role/identity, reinforcement, and emotions. CONCLUSIONS: The COM-B model was applied successfully in this study to understand PA behavior and identify potential targets for behavior change in individuals newly diagnosed with MS. Future behavior change interventions should consider addressing these factors to generate effective PA behavior change in this population. [ABSTRACT FROM AUTHOR]

Background Limited data exist on the prevalence and distribution of sedentary behavior (SB) in multiple sclerosis (MS). Objective The objective of this paper is to describe sitting time as a metric of SB in a large national sample of people with MS. Methods A total of 8004 individuals from the North American Research Committee on MS (NARCOMS) Registry completed the sitting time question from the International Physical Activity Questionnaire in spring 2015. We present descriptive data on sitting time for the total sample and across sociodemographic, clinical, and behavioral characteristics. Results The final sample included 6483 individuals. Of these, 36.7% were classified with mild disability, 24.7% with moderate disability, and 38.6% with severe disability. Median sitting time for the total sample was 480 min/day (P25 = 310 min/day, P75 = 720 min/day). Sitting time was highest for individuals with MS who were male (540 min/day), not married (540 min/day), had a disease duration >30 years (540 min/day), were underweight (540.5 min/day), had an annual income of < $15,000 (585 min/day), presented with a progressive form of MS (600 min/day), were classified as insufficiently active (600 min/day), or presented with severe disability (661 min/day). Conclusion Sitting time is twice as high in individuals with MS compared to the general population (240 min/day). [ABSTRACT FROM AUTHOR]

Improving the capacity for physical activity interventions to maintain behavior change is a key public health concern and an important strategy for the health and independence of older adults. Ways of ensuring effective maintenance of physical activity levels in older adults are unclear. This study includes the objective measure of moderate-to-vigorous physical activity (MVPA); self-reported self-efficacy; and self-regulation at four timepoints (baseline, intervention completion at 4 months, 12-, and 18-month follow-up) from the SITLESS study, a clinical trial conducted with a cohort of community-dwelling older adults (≥65 years) from Denmark, Germany, Spain, and the United Kingdom. A cross-lagged analysis found that self-regulation and self-efficacy may be key determinants of MVPA behavior in community-dwelling older adults. More specifically, the use of behavioral support strategies represents an important correlate of MVPA behavior, and its association with MVPA may be mediated by self-regulation and self-efficacy in older adults in the short and long term.

Introduction: Multiple Sclerosis (MS) is achronic neurological condition that requires costly treatment for aconstellation of motor and sensory symptoms, as well as fatigue, depression, and cognitive problems. Given that this pharmacological treatment often results in side effects, there is acrucial need for low-costbehavioral treatments that are effective in further reducing MS symptoms. It has been hypothesized that physical activity may slow the neurodegenerative progression of MS. The aim of the current study was to investigate the relationship between physical activity and commonly reported MS symptoms, including fatigue, depression, and perceived cognitive impairment. Method: 86 individuals with MS responded to amail-outquestionnaire. Physical activity, fatigue, mood, and perceived cognitive impairment were assessed using the following measures: Godin Leisure-TimeExercise Questionnaire (GLTEQ), Modified Fatigue Impact Scale (MFIS), Patient Health Questionnaire (PHQ-9), and Patient Deficit Questionnaire (PDQ). Descriptive and correlational statistics were calculated to investigate the relationship between scores on the GLTEQ and scores on the MFIS, PHQ-9, and PDQ. Results: Overall, there was asignificant negative relationship between physical activity (GLTEQ) and fatigue (MFIS; r= –.34, p=.002) and depression (PHQ-9; r= –.23, p=.034) in individuals with MS. There was not asignificant relationship between physical activity and overall perceived cognitive dysfunction (PDQ; r= –.19, p=.08), but when the PDQ subscales were examined, there was asignificant relationship with perceived retrospective (r = 0.24, p=.03) and prospective memory abilities (r = –.22, p=.04). When the RRMS and progressive subtypes were examined separately, we observed asimilar pattern of results for the RRMS group, but the progressive MS group did not reach significance. Conclusions: Individuals with MS who reported more strenuous and/or frequent physical activity, reported fewer problems with fatigue, depression, and perceived memory abilities.

BACKGROUND: To advance rehabilitation we need a comprehensive understanding of functioning and disability of people after stroke. OBJECTIVE: To present an overview of the methodology of the Life After Stroke In Northern Sweden Study, compare participants and non-participants regarding gender and age, and describe baseline sociodemographics, stroke characteristics and the participants' self-rated degree of recovery. METHODS: Data were collected through a study specific questionnaire, from the participants' medical records and with internationally established self-assessment tools focusing on sleep disturbances, depressive symptoms, fatigue, physical activity, and remaining physical and cognitive impairments, activity limitations, participation restrictions and life satisfaction. RESULTS: Of 301 potential participants, 160 comprise the final sample (response rate 53%; 86 men and 74 women, mean age 73 years±11, mean time since stroke onset 35 months±11; 18– 61). Most participants had an ischemic stroke (87%), were retired (84%), cohabitant (63%) and walked independently (71%). The mean self-rated degree of recovery was 75 (SD±24; 0– 100). CONCLUSIONS: These baseline data together with forthcoming studies will describe stroke-related impairments, activity limitations, participation restrictions and life satisfaction more than one year after stroke, and deepen our understanding of factors of importance for a healthy and successful life after stroke.

Although enjoyment has been linked to participation in physical activity (PA), a thorough analysis of the concept is lacking. Health-related behavior research emphasizes the necessity of focusing on individual psychological requirements, such as enjoyment in PA, to boost children and adolescents' motivation for PA. The current paper is a report on a conceptual analysis of the enjoyment of PA among children and adolescents. We adopted the concept analysis procedure by Walker and Avant. Several databases (PubMed, CINAHL, ERIC, PsychInfo, and Sport Discus) were searched and used to extract relevant articles about the enjoyment of PA. The review process yielded a final set of 72 papers. A refined definition of enjoyment in PA, attributes, cases, antecedents, and consequences of enjoyment in PA were presented. A conceptual understanding of enjoyment in PA can enable nurses to plan interventions that help children and adolescents get appropriate PA and improve their health habits. [ABSTRACT FROM AUTHOR]

Introduction: Social support influences physical activity (PA) in adolescents. However, whether mediating and moderating effects impact the relationship between them or the underlying mechanism remains unclear. This study aimed to investigate the mediating effects of self-efficacy as well as a series of moderating influences using a meta-analytic approach. Methods: A total of 56 studies published between January 2001 and May 2023 were obtained from the Web of Science, EBSCO, Taylor and Francis, Scopus, Wiley, ProQuest, and CNKI (core) databases, comprising 65 independent samples (total sample size = 47,196). Results and discussion: The mean weighted correlation coefficients between social, family, peer, and school support and adolescent PA were 0.298, 0.226, 0.256, and 0.142, respectively, which were significant, except for school support. Family support and teenage PA were related, although the connection was moderated by gender and socioeconomic characteristics. While social, family, and peer support had a direct influence on adolescent PA, school support did not. Self-efficacy mediated the relationship between social support and its subtypes and adolescent PA. [ABSTRACT FROM AUTHOR]

Objective: To provide both empirical support and a theoretical framework for systematically improving and optimizing the cognitive capabilities of college students through physical activity, while considering the mediating and regulating impacts of self-efficacy and negative emotion. Methods: The study employed an overall random sampling method, examining 500 college students from five universities in Jiangsu Province using the Physical Activity Rating Scale (PARS-3), Adult Executive Function Scale (ADEXI), Positive and Negative Emotion Scale (PANAS), and General Self-Efficacy Scale (GSES). Results: The findings indicated that the average age of the participants was 18.41 ± 0.73 years, encompassing 215 male students (43%), and 185 female students (57%). Engagement in physical activity was significantly and positively correlated with executive function (β = 0.246, p < 0.01), inversely associated with negative emotion (β = -0.137, p < 0.01), and demonstrated a significant positive predictive impact on self-efficacy (β = 0.183, p < 0.01). Self-efficacy was observed to partially mediate the relationship between executive function and physical activity. In addition, negative mood was identified as playing a partial mediating and modifying role in the relationship between executive function and physical activity. Conclusion: Increasing college students' daily physical activity participation not only benefits their executive function, self-efficacy, and confidence levels but also exerts a limited positive impact on negative mood, with the potential to regulate the intensity of negative emotion.
