Objectives This study aimed to explore the associations of liver biomarkers with cardiometabolic risk factors and their clustering, and to provide reference values (percentiles) and cut-off points for liver biomarkers associated with high cardiometabolic risk in European adolescents. Methods Alanine aminotransferase ( ALT), gamma-glutamyltransferase ( GGT), aspartate aminotransferase to ALT ratio ( AST/ ALT), waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol and insulin were measured in 1084 adolescents. We computed a continuous cardiometabolic risk score and defined the high cardiometabolic risk. Results Higher ALT and GGT and lower AST/ ALT were associated with adiposity and with the number of adverse cardiometabolic risk factors ( Ps < 0.05). Higher GGT and lower AST/ ALT were associated with higher cardiometabolic risk score ( Ps < 0.001) in males and females, and ALT only in males ( Ps < 0.001). Gender- and age-specific percentiles for liver biomarkers were provided. Receiver operating characteristic analyses showed a significant discriminatory accuracy of AST/ ALT in identifying the low/high cardiometabolic risk ( Ps < 0.01) and thresholds were provided. Conclusions Higher GGT and lower AST/ ALT are associated with higher cardiometabolic risk factors and their clustering in male and female European adolescents, whereas the associations of ALT were gender dependent. Our results suggest the usefulness of AST/ ALT as a screening test in the assessment of adolescents with high cardiometabolic risk and provide gender- and age-specific thresholds that might be of clinical interest.

We aimed to examine (a) the construct validity and reliability of the International Fitness Scale ( IFIS) in children; and (b) the association of both self-reported and measured fitness with cardiometabolic risk. Cross-sectional study in 1145 Spanish children (9-12 years). We measured body fat, waist circumference, blood pressure, lipids, insulin, and fitness level (reported and measured). A validated cardiometabolic syndrome index was used. An age- and sex-matched sample of 245 children originally not included in the study sample fulfilled IFIS twice for reliability purposes. IFIS was able to correctly classify children according to their measured fitness levels (analysis of covariance, adjusted for sex and age was used). Test-retest reliability of IFIS items was also good, i.e., average weighted Kappa = 0.70. Our data also suggest that both measured and reported cardiorespiratory, and speed and agility fitness were associated with cardiometabolic risk factors, such as adiposity and a cardiometabolic syndrome risk score. The associations for muscular fitness (both reported and measured) differed depending on how it was expressed (i.e., absolute vs relative terms). Our findings suggest that self-reported fitness, as assessed by IFIS, is a valid, reliable, and health-related measure, and it can be a good alternative at population level when physical fitness cannot be measured.

To investigate the combined influence of diet quality and physical activity on cardiovascular disease ( CVD) risk factors in adolescents, adolescents ( n = 1513; 12.5-17.5 years) participating in the Healthy Lifestyle in Europe by Nutrition in Adolescence study were studied. Dietary intake was registered using a 24-h recall and a diet quality index was calculated. Physical activity was assessed by accelerometry. Lifestyle groups were computed as: healthy diet and active, unhealthy diet but active, healthy diet but inactive, and unhealthy diet and inactive. CVD risk factor measurements included cardiorespiratory fitness, adiposity indicators, blood lipid profile, blood pressure, and insulin resistance. A CVD risk score was computed. The healthy diet and active group had a healthier cardiorespiratory profile, fat mass index ( FMI), triglycerides, and high-density lipoprotein cholesterol ( HDL- C) levels and total cholesterol ( TC)/ HDL- C ratio (all P ≤ 0.05). Overall, active adolescents showed higher cardiorespiratory fitness, lower FMI, TC/ HDL- C ratio, and homeostasis model assessment index and healthier blood pressure than their inactive peers with either healthy or unhealthy diet (all P ≤ 0.05). Healthy diet and active group had healthier CVD risk score compared with the inactive groups (all P ≤ 0.02). Thus, a combination of healthy diet and active lifestyle is associated with decreased CVD risk in adolescents. Moreover, an active lifestyle may reduce the adverse consequences of an unhealthy diet.

To analyze the effects of an intervention focused on increasing the time and intensity of Physical Education ( PE), on adolescents' cognitive performance and academic achievement. A 4-month group-randomized controlled trial was conducted in 67 adolescents from South- East Spain, 2007. Three classes were randomly allocated into control group ( CG), experimental group 1 ( EG1) and experimental group 2 ( EG2). CG received usual PE (two sessions/week), EG1 received four PE sessions/week and EG2 received four PE sessions/week of high intensity. Cognitive performance (non-verbal and verbal ability, abstract reasoning, spatial ability, verbal reasoning and numerical ability) was assessed by the Spanish Overall and Factorial Intelligence Test, and academic achievement by school grades. All the cognitive performance variables, except verbal reasoning, increased more in EG2 than in CG (all P < 0.05). Average school grades (e.g., mathematics) increased more in EG2 than in CG. Overall, EG2 improved more than EG1, without differences between EG1 and CG. Increased PE can benefit cognitive performance and academic achievement. This study contributes to the current knowledge by suggesting that the intensity of PE sessions might play a role in the positive effect of physical activity on cognition and academic success. Future studies involving larger sample sizes should confirm or contrast these preliminary findings. [ABSTRACT FROM AUTHOR]

What is already known about this subject Eating disorders are among the public health issues facing adolescents., An excess of body fat has been associated with an increased risk of these disorders., The association of physical fitness with eating disorders has not yet been analysed in adolescents., What this study adds This study confirms that the overweight and obesity increase the risk of developing eating disorders., The present study shows that there is an inverse association between physical fitness levels and the risk of eating disorders., This study suggests that physical fitness might attenuate the influence of overweight on the development of eating disorders in adolescents., Background Eating disorders together with the overweight and obesity are important health concerns in adolescents. Objective To analyse the individual and combined influence of overweight and physical fitness on the risk of developing eating disorders in Spanish adolescents. Methods The sample consisted of 3571 adolescents (1864 females), aged 13 to 18.5 years, from Spain who participated in the AVENA and AFINOS studies. The risk of eating disorders was evaluated using the SCOFF questionnaire. Body mass index was calculated and the adolescents were classified into two groups: overweight (including obesity) and non-overweight according to Cole's cut-off points. Cardiorespiratory fitness in the AVENA Study was assessed by the 20-m shuttle-run test and the overall physical fitness level was self-reported in the AFINOS Study. Results Overweight adolescents had a higher risk of developing eating disorders than non-overweight adolescents (odds ratio [ OR] = 4.91, 95% confidence interval [ CI]: 3.63-6.61 in the AVENA Study and OR = 2.45, 95% CI: 1.83-3.22 in the AFINOS Study). Also, adolescents with medium and low levels of physical fitness had a higher risk of developing eating disorders ( OR = 1.51, 95% CI: 1.05-2.16, and OR = 2.25, 95% CI: 1.60-3.19, respectively, in the AVENA Study, and OR = 1.73, 95% CI: 1.37-2.17, and OR = 4.11 95% CI: 2.98-5.65, respectively, in the AFINOS Study) than adolescents with high levels of physical fitness. In both studies, the combined influence of overweight and physical fitness showed that adolescents with lower levels of physical fitness had an increased risk of developing eating disorders in both non-overweight and overweight groups. Conclusions Physical fitness might attenuate the influence of overweight on the development of eating disorders in adolescents. [ABSTRACT FROM AUTHOR]

We aimed to (a) examine the validity and reliability of the International FItness Scale ( IFIS) in Spanish young adults and (b) compare the capacity of self-reported vs measured fitness to predict cardiovascular disease ( CVD) risk. The study comprised 276 participants (18-30 years). Fitness level (overall and specific components) was both self-reported ( IFIS) and measured using standard fitness tests. Total and trunk fat was assessed by dual-energy X-ray absorptiometry. We computed a previously validated metabolic syndrome score. A separate sample of 181 of same age and characteristics fulfilled IFIS twice for reliability purposes. The results of the present study support the validity and reliability of self-reported fitness, as measured by IFIS, in Spanish young adults. Our data also suggest that not only measured cardiorespiratory fitness but also self-reported cardiorespiratory fitness predicts CVD risk, as assessed by adiposity and metabolic syndrome indicators. The associations for muscular fitness (both reported and measured) differed depending on how it was expressed (i.e., absolute vs relative terms). Self-reported fitness, as assessed by IFIS, can be a good alternative when physical fitness cannot be measured in large surveys. [ABSTRACT FROM AUTHOR]

We aimed to determine the ability of a set of physical fitness tests to discriminate between presence/absence of fibromyalgia ( FM) and moderate/severe FM. The sample comprised 94 female FM patients (52 ± 8 years) and 66 healthy women (54 ± 6 years). We assessed physical fitness by means of the 30-s chair stand, handgrip strength, chair sit and reach, back scratch, blind flamingo, 8-feet up and go, and 6-min walking tests. Patients were classified as having moderate FM if the score in the Fibromyalgia Impact Questionnaire ( FIQ) was <70 and as having severe FM if the FIQ was ≥70. FM patients and patients with severe FM performed worse in most of the fitness tests studied ( P < 0.001). Except the back scratch test, all the tests were able to discriminate between presence and absence of FM [area under the curve ( AUC) = 0.66 to 0.92; P ≤ 0.001], and four tests also discriminated FM severity ( AUC = 0.62 to 0.66; P ≤ 0.05). The 30-s chair stand test showed the highest ability to discriminate FM presence and severity ( AUC = 0.92, P < 0.001; and AUC = 0.66, P = 0.008, respectively), being the corresponding discriminating cutoffs 9 and 6 repetitions, respectively. Physical fitness in general, and particularly the 30-s chair stand test, is able to discriminate between women with FM from those without FM, as well as between those with moderate FM from their peers with severe FM.

The present study investigated the association between cardiorespiratory fitness (CRF) and dietary intake in European adolescents. The study comprised 1492 adolescents (770 females) from eight European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. CRF was assessed by the 20 m shuttle run test. Adolescents were grouped into low and high CRF levels according to the FITNESSGRAM Standards. Dietary intake was self-registered by the adolescents using a computer-based tool for 24 h dietary recalls (HELENA-Dietary Assessment Tool) on two non-consecutive days. Weight and height were measured, and BMI was calculated. Higher CRF was associated with higher total energy intake in boys (P = 0·003). No association was found between CRF and macronutrient intake (as percentage of energy), yet some positive associations were found with daily intake of bread/cereals in boys and dairy products in both boys and girls (all P < 0·003), regardless of centre, age and BMI. CRF was inversely related to sweetened beverage consumption in girls. These findings were overall consistent when CRF was analysed according to the FITNESSGRAM categories (high/low CRF). A high CRF was not related to compliance with dietary recommendations, except for sweetened beverages in girls (P = 0·002). In conclusion, a high CRF is associated with a higher intake of dairy products and bread/cereals, and a lower consumption of sweetened beverages, regardless of centre, age and BMI. The present findings contribute to the understanding of the relationships between dietary factors and physiological health indicators such as CRF. [ABSTRACT FROM AUTHOR]

The aim of the study was to describe anthropometric and physical characteristics of elite young road-race motorcyclists (MC). 27 riders (15.6 ± 1.1 years, 54.6 ± 6.9 kg, 166.9 ± 6.7 cm) competing at international elite level participated in this study. Anthropometric variables, hand grip and lumbar isometric strength, and lower-body muscular strength were measured. Comparisons of the MC and a reference group of Spanish physically active adolescents (16.0 ± 0.6 years) showed that the riders were significantly lighter (-12.5 kg), and smaller (-4.7 cm). Riders also had significantly lower values for almost all skinfolds, and for all the measured girths (except forearm) than the reference group. Motorcyclists showed significantly less percent body fat (%BF) and higher muscle mass, and differences were observed for somatotype components compared to the reference group, except for the ectomorphy. Somatotype could be defined as mesomorphic-ectomorph (2.5-4.4-3.7). Mean (±SD) values of all riders were 34.8 ± 5.0 cm for vertical jump height, 402.1 ± 74.5 N for the right hand and 370.7 ± 77.5 N for the left hand strengths, and 120.6 ± 19.3 kg for lumbar isometric strength, respectively. Results demonstrate that MC are small and light, with lower body mass index, skinfolds, girth and breadth dimensions, and %BF than a reference group and other athletes, with high values of hand grip and lumbar isometric strength.

Background: Cystic Fibrosis (CF) is a genetic life limiting disease that impacts upon quality of life. An aim of CF care is to preserve lung function, with physical activity (PA) being an important part of daily airway clearance. Ensuring children have opportunities to engage in PA at school should be an important part of their daily routine. It is important to gain parental perspectives on this, as they manage the daily care for their children. This study aims to explore parents' perceptions of school-based PA for their children with CF. Methods: Parents of children with CF (n = 10), from three regions of the UK (England, Wales and Northern Ireland) took part in online semi-structured interviews. Data were analysed using Interpretative Phenomenological Analysis (IPA). Results: Although parents recognized the benefits of school-based PA for their children, systemic barriers in the school setting often inhibit daily PA for children with CF, including teachers' misconceptions, emotional and physical barriers, and PA not being a priority. Conclusion: Recommendations for practice have been developed to help engage children with CF in daily school-based PA in an inclusive way, with the hope of maintaining health outcomes for children with CF.

The purpose of the present study was to investigate the individual and combined impact of physical fitness components at baseline on health-related quality of life (HRQoL) at 24-month follow-up in adolescents. This longitudinal research included 199 adolescents (13.9±0.3 years at baseline) from the DADOS study. Cardiorespiratory fitness was assessed using the 20-m shuttle run test. Muscular strength was assessed using the standing broad jump test. Motor competence was assessed using the 4 × 10-m shuttle run test. A physical fitness z-score was calculated as the mean of the z-scores values of each fitness test. A fitness index ranging from 0 to 3 was created according to the number of physical fitness components in which participants achieved high levels according to normative values. HRQoL was evaluated by the KIDSCREEN-10 questionnaire. Linear regression analyses showed that cardiorespiratory fitness, muscular strength, and the physical fitness z-score at baseline were individually associated with HRQoL at follow-up (β ranging from 0.123 to 0.183; all p < 0.05). Moreover, logistic regression analysis revealed that adolescents with a fitness index ≥1 at baseline were more likely to achieve high HRQoL at 24-month follow-up, compared with their peers with an index of 0 (OR ranging from 3.554 to 9.087; all p < 0.05). Our results revealed an individual and cumulative positive impact of physical fitness at baseline on HRQoL at 24-month follow-up. These findings underline the key role of promoting the enhancement of overall physical fitness components in order to improve adolescents' health and well-being. Highlights Adolescents with high levels of cardiorespiratory fitness, muscular strength and motor competence will benefit from a greater physical and mental well-being over the time. The more physical fitness components with optimal levels, the greater likelihood of reaching better HRQoL over the time. Public health authorities should focus on the promotion of multiple physical fitness components to increase adolescent's likelihood of achieving greater HRQoL over the time. [ABSTRACT FROM AUTHOR]

Purpose. Maintaining physical activity (PA) has significant implications for health. According to the World Health Organization (WHO), adults aged 18–64 should engage in at least 150 to 300 minutes of moderate‐intensity aerobic PA per week. However, urban‐rural disparities and economic geography variations in PA levels have not received enough attention. This study aimed to examine these disparities in the likelihood of meeting PA recommendations by using data from the Study of Community Sports in China. Methods. This is a nationwide cross‐sectional community‐based study. A total of 5,000 participants were randomly selected using a multistage sampling strategy. They were asked to complete a survey including demographics data and PA levels. The data were analyzed using mixed‐effects logistic regression to evaluate the association between urban‐rural residency, economic geography regions, and the likelihood of meeting PA recommendations. Results. A total of 3,779 participants met the eligible criteria, and only 816 (21.6%) met the PA recommendation. The urban participants were more likely to meet the PA recommendation than their rural peers [OR (95% CI) of 1.72 (1.09, 2.71)]. The association remained significant among those aged ≥30 [OR = 2.53 (1.51, 4.24)] and those with the education of high school and below [OR = 1.88 (1.18, 1.77)], but not in their younger, and more‐educated peers (Pinteraction = 0.009 and 0.034, respectively). Compared with the east coastal residents, western ones had a greater chance of meeting the recommendation [OR = 2.68 (1.25, 5.74)]. The association was more prominent among the more‐educated [OR = 3.89 (1.58, 9.57)] than the less‐educated [1.90 (0.83, 4.35)](Pinteraction <0.001), but not modified by age. Conclusion. Urban and western residents were more active than their rural and east coastal counterparts. Studies should carefully consider the interactions between age and education level with urbanization and region while evaluating PA levels. Moreover, policymakers should develop policies and programs according to urban‐rural disparity and regional variations to shorten the gaps. [ABSTRACT FROM AUTHOR]

The study objectives were 1) to determine the feasibility and acceptability of indoor activities to achieve moderate-to-vigorous physical activity (MVPA) in preschoolers, and 2) compare MVPA estimates between direct observation (DO) and various accelerometry placements. In this cross-sectional study, 35 preschoolers (51% female, 54% 3-year-olds) performed six, 6-minute activities (dancing to video, balloon/bubbles, stationary exergame cycling, circuits, running-in-place, and cleaning up) in sequential order, facilitated by a trained staff member. Triaxial accelerometers (Actigraph Gt3×BT) at the ankle, waist, and wrist measured MVPA using age-specific cut-points. Total activity and MVPA time were quantified via DO of video recordings. Feasibility and acceptability were assessed via parent and child report. Preschoolers contributed 4339, 15-second epochs of accelerometry and DO data (~31.0 minutes/preschooler). Preschoolers achieved MVPA ≥ 50% of the time while engaging in balloon/bubbles, cycling, and circuits; but not while dancing to video (15%), running-in-place (48.5%), or cleaning up (8%). There were no differences in MVPA by age, sex, or between screen and non-screen activities. Parents and preschoolers reported most activities were feasible (≥4.0/5.0). Waist and ankle accelerometry had strong agreement with DO (ICCs range: 0.70–0.84) while wrist had fair to low agreement (ICCs: 0.22–0.58). Multiple indoor activities show promise to increase preschoolers' MVPA. [ABSTRACT FROM AUTHOR]

We investigated the longitudinal associations between sports participation patterns in youth and physical activity (PA) in adulthood. PA was self-reported triannually between ages 9–18 (n = 2550, 52% females) and measured by accelerometers in mid-adulthood (n = 1002, 61% females, aged 48 ± 4 years). Three latent classes of youth sports participation emerged for both genders: 1) "organized sports" (persistent high PA with regular sports club activities), 2) "unorganized sports" (persistent high PA without sports club activities and 3) "low activity" (low PA with decreasing sports involvement). These groups comprised 29%, 34% and 37% of males, and 23%, 27% and 50% of females, respectively. Youth "organized sports" was associated with higher adult PA in both males (+1166 steps/day, p = 0.012) and females (+15 min/day moderate-to-vigorous PA [MVPA], +1064 steps/day, +1066 leisure-time steps/day; p ≤ 0.005) compared to "low activity". In males, youth "organized sports" was associated with higher adult PA (+1103 steps/day, −26 min/day sedentary time and +133 counts/minute higher total PA, p ≤ 0.039) compared to "unorganized sports". In females, "unorganized sports" in youth was related to higher adult PA (+10 min/day MVPA, p = 0.034) when compared to "low activity". Sustained participation in youth organized sports, and for females, also in unorganized sports, is positively linked with adult PA. [ABSTRACT FROM AUTHOR]

This review aims to investigate the dose–response relationship between walking speed and all-cause mortality. PubMed, Web of Science, Embase and Cochrane Library were searched to September, 2023 for cohort studies. A meta-analysis estimated the overall hazard ratio (HR) of mortality incidence and 95% Confidence Interval (CI) for individuals with the fastest walking speed compared to those with the slowest walking speed. Subgroup analyses were conducted based on sex, age and speed-measuring methods. Dose–response meta-analyses were examined by using "mvmeta" packages available in STATA. A total of 13 studies involving 530,841 participants were included. Of these, 11 studies provided data for dose–response meta-analyses. Individuals in the fastest walking-speed category had a 43% lower risk of all-cause mortality compared to those in the slowest walking-speed category (HR = 0.57, 95% CI 0.48–0.66). There was an inverse linear dose–response relationship between walking speed and all-cause mortality; for every 0.1 m/s increment in walking speed, the risk of mortality decreased by 6% (HR = 0.94; 0.92–0.96). There was an inverse nonlinear dose–response relationship between them when participants' age was larger than 65 years, but linear dose–response relationships were detected in both the timed walking speed test and self-reported walking speed measurements.

Background: A negative lifestyle has a reported relationship with psychological problems and deteriorated well-being. However, there is little information regarding the mediating role of cardiorespiratory fitness (CRF) in this relationship. Objectives: The objectives of the present study are twofold: first, to investigate the association between negative lifestyle, physical self-concept (PSC), and depression, and second, to assess the potential mediating role of CRF in this complex relationship. Methods: This cross-sectional study included 612 schoolchildren aged between 9 and 14 years from the Araucanía region (southern Chile). CRF was measured using the Leger test, and lifestyle, depression, and PSC were measured using validated questionnaires. Results: A negative lifestyle reported an inverse association with PSC (p < 0.001) and a positive association with depression levels (p < 0.001). The mediation analysis showed that CRF was positively related to PSC (p < 0.001) and inversely related to depression (p = 0.001); besides, the indirect effect CRF acted as a partial mediator in the association between a negative lifestyle and PSC (indirect effect = −1.15; SE = 0.01; 95% CI, −1.87, −0.55) and depression levels (indirect effect = 0.22; SE = 0.08; 95% CI, 0.08, 0.38). Conclusion: In conclusion, CRF in schoolchildren played a potential mediating role in the association between a negative lifestyle and depression and PSC. [ABSTRACT FROM AUTHOR]

Background: Monitoring anthropometry, dietary intake, and physical activity (PA) is essential to prevent/counteract childhood obesity. This study examined dietary intake, PA, and anthropometric characteristics in young boys practicing soccer as a recreational sport. Methods: A cross-sectional study included 226 boys aged 8 to 13 years participating in soccer as a recreational activity in football academies located in Tunis, Tunisia. Anthropometric measures allowed the calculation of body mass index, fat mass, and peak height velocity as markers of biological maturity. A three-day food record and a food frequency questionnaire estimated nutrient intake and eating habits. The International Physical Activity Questionnaire (IPAQ) was used to estimate the PA level of the participants. Results: It was found that a high percentage of the children had excess weight (54%) and excess fat mass (47%). The total energy, carbohydrate, and saturated fat intake of the children exceeded the recommended levels by approximately 10%, 15%, and 30%, respectively. However, the intake of unsaturated fat was below the estimated requirements, particularly in obese children. In addition to the unbalanced macronutrient intake, the children also showed an insufficient intake of many essential micronutrients. Around 60% to 70% of the children in all three groups had a low intake of magnesium, n-3 polyunsaturated fatty acids (PUFA), and vitamins B9, B12, and D. Moreover, 20% to 35% of the children in the three groups had an insufficient intake of vitamins A and C. Insufficient vitamin E intake was found in 63% of obese children and 35% of non-obese children. It was observed that the PA level was lower in the overweight/obese group compared to the normal-weight group (p < 0.005). More than three-quarters of overweight/obese children had low PA levels, about 20% were moderately active, and only 1 to 2% were highly active. Conversely, normal-weight children showed moderate to high PA levels. Conclusions: Poor eating behavior, an unbalanced diet, and a low PA level are prevalent in Tunisian boys practicing recreational sports. Such a combination is responsible for a disparity between energy intake and expenditure, contributing to weight excess and increased cardiometabolic risk. The study findings provide meaningful information for practitioners and authorities on applying a balanced diet and adequate PA to prevent and fight against obesity and improve cardiometabolic health in youth.

Objectives: The study aimed to assess the occurrence of body posture disorders and their changes under the influence of a physioprophylactic program in children depending on body weight. Methods: In the examined children, the general and segmental body composition and body posture were determined using a physiotherapeutic assessment based on the Kasperczyk method. Mass, overall, and segmental body composition were determined using the bioelectrical impedance method using a TANITA body composition analyzer. The study group of 76 children was divided due to body weight disorders into Group I (n = 51), in which BMI and fat mass values were within the normative limits for age and gender, and Group II (n = 19), comprising children whose body weight exceeded the norm and/or fat mass exceeded normative values. The examined children underwent a physioprophylactic. The program was conducted by qualified physiotherapists for 12 weeks, once a week for 30 min. The therapeutic program was focused on physioprevention of being overweight and the correction of body posture. Results: A distal distribution of fat mass was observed in the examined group. Asymmetry in the sagittal plane was found in 35% of children. No statistically significant differences were found in the presence of asymmetry in the sagittal plane between the groups. No statistically significant differences were found in the occurrence of posture irregularities between the groups. Conclusions: There were no changes in the weight and body posture of the examined children under the influence of the physiotherapy program. The lack of correlation in the examined group between body weight and posture irregularities in 5–6-year-olds may suggest the acquisition of posture defects as a consequence of the persistence of overweight or obesity.

Background: Ensuring the physical fitness of Egyptian children is of paramount importance to their overall well-being, given the unique socio-cultural and educational barriers they face that may hinder their active participation. As part of the DELICIOUS project, the "Be Fit Program" aims to increase the level of physical fitness among Egyptian school-aged children. This study explores the effectiveness of a structured, six-week physical activity (PA) program in improving various facets of physical fitness in children, including body composition, speed, coordination, muscular strength, and cardiovascular endurance. With the increasing prevalence of sedentary lifestyles, such efforts are imperative to improve overall health outcomes. Methods: A cohort of 125 children, aged 8.50 to 12.25 y (mean age 10.19 ± 1.03 y), participated in the study. Their body composition, speed, coordination, strength, and aerobic fitness were assessed before and after the Be Fit Program using the revised International Physical Performance Test Profile. Paired t-tests were used to detect changes between the pre- and post-tests. Results: Following the six-week intervention, statistical analyses revealed significant improvements in coordination and lower body strength (p < 0.01). Aerobic endurance showed marginal improvements, approaching statistical significance (p = 0.06). Conversely, there were no statistically significant changes in body composition, speed, or upper body strength (p > 0.05). Conclusions: The study confirms that tailored, non-competitive physical activities can positively influence specific fitness components in Egyptian children. However, achieving holistic improvements across all targeted fitness domains may require further strategic adjustments or a longer program duration. This pilot study underscores the importance of culturally tailored, school-based PA programs and highlights the continued need for research and program refinement to comprehensively improve children's fitness in the Egyptian context.

Background: Heart rate variability (HRV), an index of the functional status of the autonomic nervous system (ANS), provides an opportunity for early detection of ANS dysfunction. Lower resting, vagally related HRV parameters are associated with increased risk of physical and mental illness. External factors influencing the ANS, such as the testing environment, may impact the interpretation of HRV. This study's main aim was to determine the reliability of HRV resting and reactivity tests performed at home with children aged 4–9 years. Methods: Fourteen healthy children (female n = 8) aged 6.8 ± 1.5 years participated. Two HRV tests were performed at home via online supervision 7 days apart using a Polar H10 heart rate monitor. The absolute and relative reliability of the pre-exercise resting (5 min) and sub-maximal exercise step test recovery (4 × 30 s segments) HRV time and frequency domains were calculated. Results: The Pearson correlation coefficients for day 1 versus day 7 for the vagal activity HRV domains (RMSSD log) at rest and in the first 30 s and 30–60 s of recovery indicated good-to-excellent relative reliability (r > 0.8, p < 0.01). Absolute reliability was moderate for the resting RMSSD log, with a coefficient of variation (CV) of 5.2% (90% CI: 3.9, 7.8%), high for the first 30 s of standing recovery, with a CV of 10.7% (90% CI: 8.2, 15.7%), and moderate for 30–60 s of recovery, with a CV of 8.7% (90% CI: 6.6, 12.9%). Conclusions: The findings of this pilot study indicate that the resting and exercise recovery HRV measures of vagal activity can be measured reliably at home in children. This represents a novel "at-home" protocol for monitoring ANS health and development in children. [ABSTRACT FROM AUTHOR]

Background/Objectives: Yoga is effective for adults with arthritis but unstudied in adolescents with juvenile idiopathic arthritis (JIA). Methods: A pilot study assessed the feasibility and acceptability of an 8-week group yoga intervention for adolescents ages 14–18 with JIA. Each 75-min session included breathing techniques, relaxation, mindfulness, and modified yoga postures, using yoga props and a rope wall. An online video was available for home practice. The outcome measures administered at the baseline and at 8 weeks were physician global assessment with joint count, visual assessment with a joint damage assessment index, the Pediatric Quality of Life Arthritis Module 3.0 (Peds QL), and the visual analog scale for pain. Results: Thirteen out of 25 participants attended ≥1 class with a mean of 5.7 ± 2.2 classes. Common reasons for non-enrollment included distance, schedule, and lack of interest. The average distance to classes was 29.0 ± 41.7 miles. There was a trend toward improvement for joint count (p = 0.07), global assessment (p = 0.10), and the Pain and Hurt domain of the Peds QL (p = 0.13), but no other outcomes approached significance. Satisfaction data from an anonymous survey (n = 8) were high in all areas. Conclusions: Adolescents with JIA who attended yoga reported enjoyment, pain reduction, and interest in continued practice with no adverse events. Future studies should consider stakeholder engagement to reduce barriers and larger sample sizes to test the effectiveness. [ABSTRACT FROM AUTHOR]

(1) Background: Body image dissatisfaction has been commonly reported in adolescents with overweight/obesity and has been related to a lack of motivation to change lifestyle behaviors. Plus, a better perception of physical fitness has been related to a higher self-perception in physical aspect and social items in youths. (2) Methods: A total of 120 (59.2% males, mean age of 12.3 ± 0.9 years) middle-school adolescents participated in the present study. Anthropometric measurements were assessed following the standard procedures. Body weight perception and body image satisfaction were assessed using the Silhouette Figure Body Images Test. Self-perception profile, perceived physical fitness, and perceived difficulties in conducting physical tasks were assessed by using structured questionnaires. (3) Results: Overweight was present in 27.5% adolescents and obesity in 32.5%. A total of 89.7% of adolescents with obesity did not have a real perception of his/her weight status and 84.6% of adolescents with obesity were not satisfied with his/her body image. The self-perception of physical appearance, perceived difficulties in running, perceived overall fitness, and perceived speed/agility were lower in adolescents who were unsatisfied with their body image. Body image satisfaction was positively associated with the self-perception of physical appearance and overall fitness and negatively associated with perceived difficulties in running, independently of sex, age, and BMI. (4) Conclusions: Adolescents with obesity did not have a real perception of their weight status and were unsatisfied with their body image. The positive association between body satisfaction, a better perception of overall fitness, and less difficulties in conducting physical tasks suggests the protective role of the components of physical activity and health-related fitness on body acceptance in a critical period of life.

A person-centred approach was used to examine whether children with various actual and perceived motor competence (AMC and PMC) profiles differ in (enjoyment of) physical fitness (PF). The strength of the relationship between AMC and PMC was also assessed through aligned assessment tools. A sample of 287 7–11-year-old children (47.40% boys, Mage = 8.92 ±.78 years) was assessed on AMC with the KörperkoordinationsTest für Kinder (KTK3), and on PF with six validated fitness tests. Animated videos fully aligned with the AMC- and PF-tests were used to assess children's PMC and enjoyment of PF, respectively. Cluster analyses identified one convergent (i.e. high AMC-high PMC) and three partially convergent AMC-PMC profiles (i.e. low AMC-high PMC). Furthermore, children with relatively high AMC (i.e. high-average profile) reported higher PF (F = 30.99, p <.001), while children with relatively high PMC (i.e. average-high profile) reported higher enjoyment of PF (F = 9.02, p <.001). The correlation between AMC and PMC was significant but weak (r =.16). Overall, it seems important to invest in both children's AMC and PMC as they may support a higher (enjoyment of) PF, potentially leading to higher PA-levels. Highlights: When it comes to physical fitness, actual motor competence rather than perceived motor competence seemed to play the biggest role. As extra high perceived motor competence did not add additional benefits in terms of physical fitness, there might have been a ceiling effect of perceived motor competence. When looking at enjoyment of physical fitness, perceived motor competence seemed to be a more important factor than actual motor competence. However, profile analyses revealed that a relatively high perceived motor competence score may not fully compensate the loss of enjoyment in physical fitness when children's actual motor competence is relatively low.

We assessed whether changes in children's body mass index (BMI), physical fitness and health-related quality of life observed post-2020 United Kingdom COVID-19 lockdown remained 12 and 18 months later. Twenty-metre shuttle run test (20mSRT), handgrip strength, standing broad jump, sit-and-reach, height, body mass, and health-related quality of life (Kidscreen27 questionnaire) were measured in 90 children (8–9 years) during October 2019 ("T0"), November 2020 ("T1"), November 2021 ("T2") and June 2022 ("T3"). Mixed-effects models showed age- and sex-normalised BMI increased from T0 (mean: 0.71) to T1 (0.97), remaining elevated at T2 (0.95) and T3 (0.89). Decreases in 20mSRT performance were observed from T0 (22.0) to T1 (19.3), then increased at T2 (23.5) and T3 (28.3). Standing broad jump and handgrip strength increased over time. The proportion of children with overweight/obesity increased from T0 (32%) to T3 (48%). Health-related quality of life decreased for "Physical Wellbeing" yet increased for "Autonomy & Parents". Our findings highlight that lockdowns may have had lasting implications for children's health, and the urgent need to reduce overweight and obesity in North East England. Improving health and fitness behaviours to maximise long-term health outcomes and build resilience to future emergencies and disruptions to health behaviours is also paramount.

School-age children with overweight or obesity continue to be problematic in the United States, and are associated with many health, social, and financial problems. Schools provide an excellent venue in which to promote healthy weight in students, and school nurses are well-positioned to play an essential role in controlling obesity. The number of studies reporting relationships among school health infrastructure and prevalence of elevated Body Mass Index (BMI) is limited. The present study explored associations between three components of school health infrastructure (staff, services, budget) and the proportion overweight or obese 1st, 3rd, and 6th grade students, after controlling for selected factors (race, county education level, county poverty level, rurality). Study results supported an independent association between elevated BMI and school health staff. Additionally, independent associations between elevated BMI and the following covariates were supported: household income, race, and parents' educational level. There is an ultimate need for well-designed studies addressing these associations. [ABSTRACT FROM AUTHOR]

Aims: The aim of this study was to assess the validity and reliability of the Salutogenic Health Indicator Scale (SHIS) among a sample of Turkish university students. Methods: This study was conducted with 291 university students. The SHIS was evaluated in terms of language equivalence, validity and the reliability. Content validity was assessed with the content validity index (CVI). Construct validity was determined by confirmatory factor analysis (CFA). A Cronbach's alpha reliability coefficient was used for the analysis of internal consistency, a Pearson's correlation coefficient was used for parallel form reliability, and the intraclass correlation coefficient (ICC) was used for the test–retest technique. Results: The CVI of the SHIS was between 0.80 and 1.00. When the results of the CFA were examined, the factor loadings of all items were above 0.50. A statistically significant moderate positive correlation was found between the SHIS and the Sense of Coherence (SOC) scores for parallel form reliability (r = 0.489). Within the scope of the test–retest analysis, an ICC = 0.762 was determined (p < 0.001). Conclusion: The findings obtained from this validity and reliability study carried out on a sample of Turkish university students showed that the SHIS was both valid and reliable. Summary statement: What is already known about this topic? In recent years, as awareness of the impact of stress on human life has grown, the significance of the salutogenesis concept has increased, resulting in an upsurge in related studies.Several studies have shown the robust psychometric properties and validity of the Salutogenic Health Indicator Scale (SHIS).SHIS, being a semantic type of scale, sets it apart from other measurement scales in the literature that assess positive health and salutogenic health due to its structure. What this paper adds? The results of this adaptation study, which was carried out on a sample of Turkish university students, showed that the SHIS is a valid and reliable tool for measuring health in Turkish culture. The implications of this paper: A culturally and developmentally appropriate, valid and reliable tool can enable individuals to recognize health indicators, resources and coping skills.SHIS can be utilized by healthcare professionals, particularly nurses responsible for patient care, researchers, educators and university students. It proves valuable in conducting comprehensive evaluations of health, positive health and well‐being care, as well as in the planning, development and evaluation of suitable intervention programmes.

The aim of this study was to evaluate the feasibility and potential efficacy of a WhatsApp-based physical activity for children with autism spectrum disorder (ASD). Fourteen parents and their children with ASD participated in the study. The intervention included parents conducting physical activities with their children with ASD for 4 weeks. Physical activity contents were provided to parents via the WhatsApp group. The data were collected through the Leisure Time Exercise Questionnaire and a feasibility questionnaire adapted from previous studies examining the feasibility of web-based physical activities. Parents reported that WhatsApp-based physical activities were a feasible intervention to increase the physical activity level of their children with ASD and stated that the contents of the physical activity shared in the WhatsApp group were useful. The findings provided preliminary evidence for the use of WhatsApp-based physical activities to increase the physical activity level of children with ASD who stay at home due to the pandemic.

Introduction: Transition from primary school to high school can be a time of significant stress for young people. Social connection may mitigate the stress experienced by young people, yet their play activities, which are a key source of connection and friendship, have not been examined. The aim of the study was to capture the play behaviours of children in outdoor school environments. Methods: Children's play behaviours in their final year of primary school and those in their first year of high school were captured using a standardised tool (Tool for Observing Play Outdoors). Observations occurred in school outdoor environments during break times in the South Australian autumn of 2021. Frequencies and types of play were compared between year levels using descriptive statistics and contingency tables. Data were collected from four schools (two metropolitan and two regional), which were all from a similar level on the Index of Educational Disadvantage. Four observation sessions were held at each school. Results: Parents of 42 (16 girls) primary school students and 85 (33 girls) high school students gave permission for their children to participate. Physical play was the most frequent activity observed in both primary school and high school followed by expressive play. Year level was significantly associated with the type of play engaged in. Conclusion: Findings demonstrate children in the first year of high school continue to engage in physical and social play albeit less than those in the final year of primary school. Further research is needed to determine whether the physical and social environment or onset of puberty is more influential on changes in children's play. [ABSTRACT FROM AUTHOR]

This study aimed to detect the functional and emotional impact of COVID‐19 lockdown on institutionalized older adults with sarcopenia during a 15‐month follow‐up. A prospective longitudinal cohort study was conducted in a nursing home. Participants were screened for sarcopenia, and those with a score of ≥4 points according to SARC‐F questionnaire were included. Assessments were performed pre‐lockdown (T1), 12 months (T2) after, and at a 15‐month follow‐up (T3). Functional measurements included chair stand test, handgrip, biceps brachii and quadriceps femoris strengths, appendicular skeletal mass, gait speed, Short Physical Performance Battery, and Timed Up‐and‐Go test. Emotional assessments included Short‐Form Health Survey, Geriatric Depression Scale—Short Form, and the Mini‐Mental State Examination. The analyzed sample showed a reduction in bicep strength, and other upper and lower limb strength variables showed a decreasing trend with no changes regarding muscle mass. Physical performance showed a change, specifically a deterioration in the subtest related to balance. Cognitive and emotional components were affected and quality of life was decreased. It is of paramount importance to focus on sarcopenic older adults since their characteristics can deteriorate when isolation measures are conducted. [ABSTRACT FROM AUTHOR]

Youth with visual impairments are more likely to be overweight than peers without visual impairments and often struggle with their locomotor skills. Locomotor development can combat unhealthy body weight statuses by supporting physical activity behaviors. There are no longitudinal investigations concerning the locomotor skill and body mass index (BMI) developmental trajectories of youth with visual impairments. The purpose of this study was to examine the 3-year developmental trajectory of the locomotor skills and BMI of youth with visual impairments including differential effects of self-reported gender and degree of vision. Participants (N = 34, Mage = 11.75 years, 47% female) showed severely delayed and arrested locomotor development with increases in BMI across 3 years regardless of self-reported gender or degree of vision. Participants failed to breech a proficiency barrier of motor competence to combat against increases in BMI across time. Additional longitudinal inquiries are needed. [ABSTRACT FROM AUTHOR]

Ergogenic strategies have been studied to alleviate muscle fatigue and improve sports performance. Sodium bicarbonate (NaHCO3) has improved repeated sprint performance in adult team-sports players, but the effect for adolescents is unknown. The aim of the present study was to evaluate the effect of NaHCO3 supplementation on repeated sprint performance in semiprofessional adolescent soccer players. In a double-blind, placebo-controlled, crossover trial, 15 male semiprofessional adolescent soccer players (15 ± 1 years; body fat 10.7 ± 1.3%) ingested NaHCO3 or a placebo (sodium chloride) 90 min before performing the running anaerobic sprint test (RAST). A countermovement jump was performed before and after the RAST, and ratings of perceived exertion, blood parameters (potential hydrogen and bicarbonate concentration), and fatigue index were also evaluated. Supplementation with NaHCO3 promoted alkalosis, as demonstrated by the increase from the baseline to preexercise, compared with the placebo (potential hydrogen: +0.07 ± 0.01 vs. −0.00 ± 0.01, p < .001 and bicarbonate: +3.44 ± 0.38 vs. −1.45 ± 0.31 mmol/L, p < .001); however, this change did not translate into an improvement in RAST total time (32.12 ± 0.30 vs. 33.31 ± 0.41 s, p = .553); fatigue index (5.44 ± 0.64 vs. 6.28 ± 0.64 W/s, p = .263); ratings of perceived exertion (7.60 ± 0.33 vs. 7.80 ± 0.10 units, p = .525); countermovement jump pre-RAST (32.21 ± 3.35 vs. 32.05 ± 3.51 cm, p = .383); or countermovement jump post-RAST (31.70 ± 0.78 vs. 32.74 ± 1.11 cm, p = .696). Acute NaHCO3 supplementation did not reduce muscle fatigue or improve RAST performance in semiprofessional adolescent soccer players. More work assessing supplementation in this age group is required to increase understanding in the area. [ABSTRACT FROM AUTHOR]

The aims of the study were to examine the moderating role of physical activity in the relationship between cardiometabolic risk factors and adiponectin concentration in adolescents. This is a cross-sectional study conducted with 96 adolescents of both sexes, between 11 and 17 years old. Body mass, height, fat mass (FM), fat-free mass, systolic blood pressure, diastolic blood pressure, high density lipoprotein, low density lipoprotein (LDL-c), triglycerides, insulin, adiponectin, C-reactive protein, and level of physical activity (energy expenditure questionnaire) were measured. Body mass index (BMI), triponderal mass index (TMI), homeostasis model to assessment insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI) were calculated. Macro-PROCESS for SPSS was used for moderation analyses. Direct interactions were found for BMI, TMI, FM, insulin, and HOMA-IR and inverse for LDL-c, and QUICKI. Protection against cardiometabolic risk was found when the PA-coeff was completed above 1.57 coeff (BMI), 1.62 coeff (TMI), 1.55 coeff (FM), 1.41 coeff (LDL-c)1.60 coeff (insulin), 1.59 coeff (HOMA-IR) and 1.35 coeff (QUICKI). We conclude that physical activity was a moderator in the relationship with adiposity, insulin resistance and sensitivity, LDL-c, and adiponectin. In this context, we evidenced a relevant clinical impact on the health of adolescents, demonstrating the interaction between anthropometrics variables and physical activity. [ABSTRACT FROM AUTHOR]

The potential for high performance in many sports can be assessed by quantifying whole-body explosiveness. The backwards overhead medicine ball (BOMB) throw is commonly-used to tests this ability, but the effect of varied loading on test execution is unknown. The purpose of this study was to determine the effect of different medicine ball (MB) loads on force, velocity, and power output during the BOMB throw. Female collegiate softball and rugby players (n=31) performed the BOMB throw on a force plate using 2.7, 3.6, 4.5, and 5.5 kg MBs, with three throws per load in a randomised order, and 30 seconds rest between throws. A series of Repeated Measures ANOVAs noted no differences (p>0.05) in peak power, peak force, peak velocity, force at the moment of peak power, or velocity at the moment of peak power, across MB loads. The lack of differences among these loads indicates that coaches can likely compare kinetic characteristics of the BOMB throw within this range (2.7-5.5 kg). Therefore, coaches can use the BOMB throw with 2.7-5.5 kg MBs for training or measurement among female athletes to obtain reference data for programming or evaluation. [ABSTRACT FROM AUTHOR]

Internal and external factors can potentially affect physical activity in individual children and adolescents. Unfortunately, no study has been conducted to explore the association between these factors and physical activity among Thai children and adolescents who engage in physical activity following the guidelines set by the World Health Organization. The purpose of the study was to investigate the relationship between three internal factors: knowledge, attitude, and self-efficacy with two external factors: parental and environmental supports that encourage physical activity participation among children and adolescents. This study used a secondary data set from the Thailand Physical Activity Children Survey. This survey employed the use of questionnaires and face-to-face interviews for collecting information on physical activity participation. The participants included 2447 children aged 6–17 years. The odds ratio and 95% confidence interval were reported to reflect the strength of an association between internal and external factors and achieving the physical activity guidelines. The results showed that attitude toward physical activity and self-efficacy had an influence on achieving physical activity guidelines. The children and adolescents achieving physical activity guidelines had the confidence in themselves to do physical activity. They could spend their time doing physical activity after school, even in unfavorable conditions. Additionally, parental and environmental supports were necessary to encourage physical activity continuously. Furthermore, these results can be used for promoting a program to manage the factors related to physical activities and improve the levels of physical activity among children and adolescents [ABSTRACT FROM AUTHOR]

The aging process reflects, in many cases, not only a decline in physical activity (PA) and physical fitness (PF), but also an increase in overall levels of sedentary time (ST). In order to hierarchically identify the most powerful correlates related to low and high levels of objectively assessed PA, ST, and PF during the late adulthood, a total of 2666 older adults were cross-sectionally evaluated. Multidimensional correlates were obtained through interview. Using chi-squared automatic detection analysis to identify the cluster of correlates with most impact on PA (<21.4 min/day), ST (≥8 h/day), and PF (<33.3th percentile), was found that the most likely subgroup to be physically inactive consisted of widowers not owning a computer and sport facilities in the neighbourhood (94.7%), while not being widowed, reporting to have a family that exercises and a computer at home (54.3%) represented the subgroup less likely to be inactive. Widowers without sidewalks in the neighbourhood were the most sedentary group (91.0%), while being a married woman and reporting to have space to exercise at home (40%) formed the most favourable group of correlates regarding ST. Men reporting a financial income <500€ and physical problems frequently formed the group with the lowest PF level (70.3%). In contrast, the less likely subgroup to have low levels of PF level consisted of having a financial income ≥1000€ and a computer at home (3.4%). Future interventions should target widowers with limited accessibility to computer and urban/sport-related infrastructures, as well as impaired older adults with low financial income. Highlights Chi-squared automatic interaction detection was used to identify and hierarchise correlates of objectively measured physical activity, sedentary time, and fitness. Widowers not having a computer at home and sport facilities in the neighbourhood were the most likely to be physically inactive, while not being widowed, having a family that exercises and a computer at home represented the subgroup less likely to be physically inactive. The most likely to be classified as sedentary were widowers without sidewalks in the neighbourhood, while the most favourable group of correlates regarding ST was formed by married women and reporting to have space to exercise at home. Individuals with a low financial income and physical problems comprised the population subgroup with the lowest PF levels, while having a medium-high financial income and a computer at home represented the less likely subgroup to have low levels of PF.

This study aimed to examine the impact of reallocating time spent in waking movement behaviours at baseline on indicators of psychological distress at 24-month follow-up using isotemporal substitution regression models among a sample of Spanish adolescents. The DADOS (Deporte, ADOlescencia y Salud) study is a 3-year longitudinal observational research project carried out between years 2015–2017. The analyses included 197 adolescents (91 girls) aged 13.9 ± 0.3 years at baseline. Waking movement behaviours were assessed by a wrist-worn GENEActiv triaxial accelerometer and expressed as minutes/day of light physical activity (LPA), moderate-vigorous physical activity (MVPA) and time spent in sedentary behaviour (SB). The Behaviour Assessment System for Children and Adolescents (level 3 for adolescents) was used to assess psychological distress indicators (i.e., anxiety, social stress, and risk of depression). Results showed significant associations only for girls. The substitution of 10 min/day of SB or LPA at baseline with 10 min/day of MVPA was associated with lower levels of anxiety (both p ≤ 0.01) and social stress (both p < 0.05) at follow-up. The substitution of 10 min/day of SB with 10 min/day of LPA was associated with higher levels of anxiety at follow-up (p = 0.01). These findings highlight the need of specific physical activity recommendations for mental health paying special attention to sex-differences. [ABSTRACT FROM AUTHOR]

Identification of cardiometabolic risk (CMR) in U.S. younger population by assessing muscular strength via handgrip (HG) dynamometry may aid in prevention efforts. Currently, no nationally representative HG cut-points are available for identifying increased CMR in U.S. adolescents or young adults. In this study, we propose normalized grip strength (NGS) cut-points for U.S. younger population CMR identification. National Health and Nutrition Examination Survey 2011–2012 and 2013–2014 data sets were used for analysis. A total of 1,033 participants (female [F], n = 498; male [M], n = 535) aged 12–24 years without current infection were included in analyses. The identified age- and sex-specific NGS cut-points are: M = 0.39 and F = 0.34 (age = 12–17 years), M = 0.45 and F = 0.34 (age = 18–24 years). These cut-points may be used in U.S. public health screening routines such as school- or community-based health-related fitness surveillance programs. Future work should use these cut-points in various samples to test their predictive utility for increased CMR. [ABSTRACT FROM AUTHOR]

Globally, there is a rising prevalence of infertility, and it has a negative consequence on the quality of life of women. The researchers aimed to understand the knowledge, attitude, and practice of women with infertility toward exercises. A cross-sectional study was conducted on 332 women aged between 18 and 45 years attending an infertility clinic in a tertiary hospital in Southern India. Participants filled a self-developed, content validated, pilot-tested questionnaire. Informants perceived stress and weight gain to be the major causes of infertility. Exercise was believed to improve fertilization by 55.4% of the participants, and walking and yoga were the preferred mode of exercises. [ABSTRACT FROM AUTHOR]

Physical activity (PA) is important for children's development of fundamental motor skills (FMS) and physical fitness (FIT) but evidence regarding which intensities are associated with these outcomes in early childhood is limited. The aim of this study was to determine the cross-sectional multivariate PA intensity signatures associated with FMS and FIT in children aged 3–5 years. We used a sample of 952 Norwegian preschoolers (4.3 years, 51% boys) who provided data on PA (ActiGraph GT3X+), at least one FMS (locomotor, object control and/or balance skills) or FIT (speed agility, standing long jump, and/or handgrip strength) outcome, body mass index, and socioeconomic status in 2019–2020. We created 17 PA intensity variables (0–99 to ≥15000 counts per minute) from the vertical axis and used multivariate pattern analysis for analyses. The PA intensity spectrum (including sedentary time) was significantly associated with all outcomes. Associations for PA intensities were positive (negative for sedentary time), strongest for moderate and vigorous intensities, and were significant across sex and age groups. Our findings show that the PA intensity spectrum is associated with FMS and FIT in young children and that promotion of PA, in particular moderate- and vigorous-intensity activity, from an early age benefits children's physical development.

Aims and objectives: To investigate the association between sedentary behaviour (SB), physical activity (PA), and frailty and frailty subdomains in community‐dwelling older women. Background: Frailty is associated with numerous adverse health outcomes in older people, and women had a higher prevalence than men. However, older adults may face different health risks due to different combinations of frailty subdomains; therefore, specific studies on frailty subdomains are needed. Design: A cross‐sectional study guided by the STROBE. Methods: In total, 1099 community‐dwelling older Chinese women (60–70 years) were included. SB and PA were objectively obtained using a validated triaxial accelerometer. Frailty was defined using the Fried Phenotype (FP) Model. Results: After adjusting for confounders, a significant association was found between SB, PA and the prevalence of frailty. The optimal cut‐off values of total SB time, light PA (LPA) time, and moderate‐to‐vigorous PA (MVPA) time to discriminate between frailty and non‐frailty were 625.4 min/day, 379.3 min/day and 20.1 min/day, respectively. For frailty subdomains, total SB time was positively associated with low PA. When it comes to total LPA time, the association with low PA was negative. Total MVPA time was significantly and negatively associated with exhaustion, weakness, slowness and low PA, and the optimal cutoff value was 24.4 min/day, 26 min/day, 29.5 min/day and 20.8 min/day, respectively. Conclusions: Effective management of frailty requires consideration of different combinations of frailty subdomains. Increasing MVPA and limiting SB may help deal with frailty for community‐dwelling older Chinese women. Additional research is needed to determine whether PA are useful for prevention of frailty. Relevance to clinical practice: The results of this study could help caregivers provide professional and specific physical activity guidance for order women, who are on a risk of or already suffered frailty.

In prior research, Irish youth displayed poor motor competence across fundamental movement skills (FMS) and functional movements (FM). Our purpose in this study was to compare FMS and FM across male and female Irish adolescents and to determine whether there are associations between these movement domains. We collected data on 373 adolescents (178 females; M age = 14.38, SD = 0.87 years) from six Irish secondary schools, including motor competence testing of 10 FMS, and 7 FM. Overall levels of motor competence of both FMS and FM were low, and certain levels of dysfunctional movement were high. We observed significant sex-based differences in both FMS and FM, and there was a moderate association between FMS and FM that warrants further investigation. There is a need for societal intervention and policy changes to address low levels of motor competence among adolescent youth. [ABSTRACT FROM AUTHOR]

This study compared physical activity metrics from the activPAL (AP) worn on the thigh with the ActiGraph worn on the non-dominant wrist using open-source methods. Measures included average acceleration, intensity gradient (IG) and the minimum acceleration value of the most active X mins (MX). Fifty-two children (26 boys; age: 10.4 ± 0.6 years) provided≥1 day (24 h) of concurrent wear time from the activPAL and ActiGraph. Measures tended to be lower from the activPAL versus the ActiGraph. Poor agreement was evident for average acceleration but good for the IG. For the IG, the absolute and relative zones needed to reach equivalence was 4% and 0.4 SDs, respectively and for average acceleration were 10% and 1.2 SDs, respectively. Good agreement was evident for M60, M30, M20, M15 and M10 between devices. Regardless of the reference device used, equivalent estimates for the intensity gradient, M60, M30, M20, M15 and M10 were observed with relative and absolute equivalence zones being≤4% and≤0.5 SDs, respectively. The IG, M60, M30, M20, M15 and M10 appear good candidates for comparing activity data collected from the activPAL and ActiGraph. Future research can use the AP to report on sedentary behaviours as well as PA outcomes. [ABSTRACT FROM AUTHOR]

Despite overwhelming adoption of wearable fitness trackers (WFT), it is unclear if they affect physical activity (PA) engagement or PA motivation. We hypothesized that combining a WFT with an effective intervention, motivational interviewing (MI), would positively influence both motivation and PA. A 12-week randomized controlled trial was conducted in 40 adults who did not meet PA recommendations. The four conditions were: a PA education (Educational control, n = 10), a WFT (WFT, n = 10), bi-weekly MI sessions (MI, n = 10), or both interventions (WFT+, n = 10). Motivation and PA were measured through an online survey and actigraphy pre- and post-intervention. Both the WFT+ and MI groups improved autonomous forms and decreased controlled forms of motivation. They also had higher basic psychological needs scores when compared to the Education group post-intervention. We detected no changes in PA. High autonomous motivation at baseline predicted higher post-intervention PA in the WFT+ group but predicted lower post-intervention PA in the WFT group. Results suggests that MI alone or with a WFT can improve basic psychological needs and autonomous forms of motivation for PA, but not PA participation. Individual differences in motivation at baseline may moderate the effect of a WFT on PA. This study was registered at clinicaltrials.gov (NCT490014). [ABSTRACT FROM AUTHOR]

Young women with breast cancer (YWBC) report physical and psychological symptom distress after therapy but little is known about their sleep health. The purpose of this study was to identify sociodemographic, clinical, and psychosocial factors associated with sleep health and assess the potential role of appraisal of illness and coping on sleep health. An adapted cognitive appraisal and coping conceptual framework guided the study. We used a cross‐sectional design with 159 women who were diagnosed with stage I–III breast cancer ≤50 years old. Sleep health was measured by the Pittsburgh Sleep Quality Index (PSQI). The mean age was 43.6 years (SD = 6.8), the majority of whom were non‐Hispanic White (84%) and completed chemotherapy or radiotherapy (>70%). More than half of participants (55%) reported poor sleep health (PSQI > 8), and those with worse family functioning and from a racial/ethnic minority group were significantly more likely to have poor sleep health. Cognitive appraisal had a minimal mediation effect for anxiety on sleep health, and coping did not mediate the effect of any psychosocial variables on sleep health. Poor sleep health is a significant clinical problem in YWBC. Further research is needed to explore sleep health disparities among diverse cancer survivors and to examine sleep health in the context of family. Sleep assessment, management, and appropriate referrals to sleep providers should be part of routine survivorship care. [ABSTRACT FROM AUTHOR]

The places where adolescents live, learn, and play are thought to influence behaviours and health, but we have limited tools for measuring environmental risk on a hyperlocal (e.g. neighbourhood) level. Working with 218 adolescents and their parents/guardians in rural western Kenya, we combined participatory mapping activities with satellite imagery to identify adolescent activity spaces and create a novel measure of social-ecological risks. We then examined the associations between social-ecological risk and individual HIV risk beliefs and behaviours. We found support for the conjecture that social-ecological risks may be associated with individual beliefs and behaviours. As social-ecological risk increased for a sample of Kenyan adolescents, so did their reports of riskier sex beliefs and behaviours, as well as unsupervised outings at night. This study reinforces calls for disease prevention approaches that go beyond emphasising individual behaviour change. [ABSTRACT FROM AUTHOR]

Recently, the employee turnover rate of the modern service industry has continued to increase, leading to a decline in the service quality, customer turnover, and an increase in human costs. Meanwhile, fierce competition and enterprises' internal pressure have brought great psychological trauma to employees and affected their mental health. Understanding and finding out the factors that affect employees' resignations are the solutions to employees' mental health problems. The research innovation lies in building a relationship model between turnover intention, psychological contract, and job satisfaction; analyzing the influence mechanism and interaction of various variables in the model; and providing reference and thinking for the service industry to solve the problem of excessive turnover of employees. Besides, the questionnaire design and investigation are carried out, and 60 front-line employees of a service company are selected as the research objects. The results show that the overall internal consistency coefficient of SCL-90 is 0.96, and the overall consistency coefficient is directly proportional to the scale's reliability. The validity coefficient of SCL-90 is 0.79, which has good compatibility validity. Moreover, the correlation coefficient between the psychological contract and turnover intention is 0.621, and the Sig value is 0.00. The correlation coefficient between job satisfaction and turnover intention is −0.663, and the Sig value is 0.00. The psychological contract is positively correlated with turnover intention, and job satisfaction is negatively correlated with turnover intention. After the standard dance experiment, the P values of psychological indicators such as somatization, interpersonal relationship, depression, anxiety, and psychosis factors of employees in the control and experimental groups are all less than 0.05, indicating a significant correlation. Therefore, through 12 weeks of standard dance practice, all psychological indicators of the experimental group are significantly improved. However, the change results of the terror factor and paranoia factor are P > 0.05 , showing no significant difference. After the standard dance experiment, there is a significant difference between the control and experimental groups in mental health factors, but no significant difference in terror and paranoia factors. This study has significant reference value for the prevention of employee turnover and mental health. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to determine the effectiveness of a Pender's health promotion model‐based Physical Activity and Healthy Nutrition Program for University Students (UNI‐PAHNP) as a means for improving university students' nutrition and physical activity behaviors. Method: A total of 110 overweight and obese students were randomized into study and control groups. Findings: Students in the intervention group showed significant decreases in body mass index and waist circumference and significant increases in step count, physical activity, nutrition and exercise scores, vegetable and water intake frequency, and self‐efficacy to regulate nutrition and exercise from pre‐intervention to six months post‐intervention (p < 0.05). Practice Implications: This study shows the value of utilizing nurses to implement a health promotion program for overweight/obese university students. [ABSTRACT FROM AUTHOR]

The purpose of this randomized control trial was to observe the effect of nature‐based physical activity in achieving post traumatic growth and to estimate the combined effect of nature and physical activity on the psychophysiological outcomes. A 3‐month therapy was provided to participants meeting eligibility criteria to receive the walk‐in nature (experimental group) or sit‐in nature (control group) in the 1:1 ratio. At baseline and 3‐month follow‐up, participants were assessed with Trauma Symptom Checklist 40, Traumatic Stress Scale, Post‐Traumatic Growth Inventory (PTGI), Cortisol, C‐Reactive Protein (CRP), Interleukin‐6 (IL‐6), Brain‐Derived Neurotropic Factor (BDNF) and heart rate variability. There was a significant effect of nature‐based physical activity on traumatic stress and post‐traumatic growth in comparison with the sit‐in control. A significant post‐interventional difference was observed in the mean PTGI score [F = 5.412, p = 0.022] between the experimental and control groups after 3 months of intervention. All the biochemical estimates, including CRP, BDNF, IL‐6, and cortisol levels, were significantly altered in both post‐intervention study groups (p < 0.01). Taken together, these results show that nature‐based physical activity significantly improves psychophysiological outcomes induced as a result of post‐traumatic growth and also reduces traumatic stress.

This study examined the predictive validity of musculoskeletal fitness tests for identifying sarcopenia in youth. The sample was 529 participants age 10 to 18 years. Indices included: total lean body mass (LBM) normalized for height (LBM index, LBMI, kg/m2), appendicular LBMI (aLBMI, kg/m2), and LBM to fat body mass (FBM) ratio (LBM/FBM). Lean and fat tissue were measured via DXA. The cutoff value for sarcopenia was – 2.0 standard deviations ≤ mean for age and sex. Fitness was assessed using handgrip, plank, and vertical jump tests. Variables were standardized using the lambda-mu-sigma (LMS) method. By sex, analysis included the area under the curve (AUC), sensitivity (Se), and specificity (Sp). The ROC curves for aLBMI was highly accurate (AUCs ≥ 0.90, Se and Sp = 86–88%) for vertical jump and moderately accurate for handgrip (AUCs = 0.87–0.88, Se and Sp = 71–75%). Fitness tests can be used to identify pediatric sarcopenia. [ABSTRACT FROM AUTHOR]

The study examined the sensitivity to change of field assessments of handgrip strength and vertical jump following programmatic interventions in physical education settings. Using a naturalistic experimental design, classes of 6th grade students (N = 158) were randomized to receive either an 8-week musculoskeletal strength or plyometric power program in physical education. Two-way repeated measures (program*time) ANOVAs were used to examine pre-post changes in handgrip and vertical jump tests. Results of the two-way ANOVA examining changes in vertical jump scores revealed a statistically significant program*time interaction effect (p <.001) with larger gains in the plyometric power group. The parallel analysis on handgrip was not statistically significant, but percent changes in handgrip scores were larger in the musculoskeletal strength group. The results are consistent with the specificity principle and demonstrate that field-based musculoskeletal fitness assessments are sensitive to change if students receive appropriately designed musculoskeletal programming in physical education classes.
