Physical activity (PA) and sports are efficient ways to promote the younger generation’s health and wellbeing. However, evidence is limited due to heterogeneous samples and measurements. This study aims to identify promoting and inhibiting correlates associated with children’s and adolescents’ non-organized PA participation and further demonstrate the complexity of PA and ecological factors. A systematic review and meta-analysis will be applied by following the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). Seven bibliographic databases (PubMed, SPORTDiscus, PsycInfo, MEDLINE Complete, ERIC, Dimensions, and Academic Search Complete) will be systematically searched to identify eligible articles based on a series of inclusion and exclusion criteria. Inclusion criteria are that the study: (a) is not classified as a systematic review with or without meta-analysis; (b) is published in last 20 years; (c) includes children and adolescents; (d) quantitively measures PA; (e) includes review of ecological factors. The internal validity will be evaluated using a validated quality instrument. Calculations will be produced in SPSS 27.0 and Comprehensive Meta-Analysis 3.3. This study will provide evidence and address the questions regarding the factors that significantly impact children’s PA participation and limitations regarding the design, sampling, and measurement in currently selected studies. PROSPERO registration number: CRD42021244918.

Physical activity (PA) and sports are efficient ways to promote the young generation’s physical and mental health and development. This study expected to demonstrate the complexity of correlates associated with children’s and adolescents’ non-organized PA participation. Following the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA), a systematic review and meta-analysis were applied. Seven electronic databases were systematically searched to identify eligible articles based on a series of inclusion and exclusion criteria. The internal validity of the systematic reviews thus identified was evaluated using a validated quality instrument. Calculations were produced in SPSS 27.0 and Comprehensive Meta-Analysis 3.3. Thirty-nine eligible studies (N = 324,953) with moderate to high quality were included. No potential publication bias was detected using statistical analyses. The meta-analysis revealed that the overall ecological factors correlated positively with children and adolescents’ PA; the meta-analytic average of the correlations was (′r = 0.32, p < 0.001). Results from subgroup analysis indicated that theory-based influence factors achieved moderate effect with boys (′r = 0.37, p < 0.001) and girls (′r = 0.32, p < 0.001) in PA participation. Interestingly, higher correlations were found between ecological factors and twins’ PA participation (′r = 0.61, p = 0.001). Further, individual (′r = 0.32, p < 0.001), macro-, and chronosystems factors (′r = 0.50, p < 0.001) appeared slightly more influential than microsystems factors (′r = 0.28, p < 0.001) on children and adolescents’ PA participation. Although findings from the included studies covered were to some extent heterogeneous, it is possible to identify consistent correlates of PA in children and adolescents. The results supported that PA is a complex and multi-dimensional behavior, which is determined by numerous biological, psychological, sociocultural, and environmental factors. Future studies that focus on the integration effect of macrosystem and chronosystem environmental factors, and apply longitudinal designs and objective measurements are encouraged to further unfold the complexity of the ecological system and its implications in promoting children and adolescents’ PA participation.

Muscle Fitness

Physical activity could improve the muscle fitness of youth, but the systematic analysis of physical activity elements and muscle fitness was limited. This systematic review and meta-analysis aim to explore the influence of physical activity elements on muscle fitness in children and adolescents. We analyzed literature in Embase, EBSCO, Web of Science, and PubMed databases from January 2000 to September 2020. Only randomized controlled studies with an active control group, which examined at least 1 muscle fitness evaluation index in individuals aged 5–18 years were included. Articles were evaluated using the Jaded scale. Weighted-mean standardized mean differences (SMDs) were calculated using random-effects models. Twenty-one studies and 2267 subjects were included. Physical activity had moderate effects on improving muscle fitness (SMD: 0.58–0.96, p < 0.05). Physical activity element subgroup analysis showed that high-intensity (SMD 0.68–0.99, p < 0.05) physical activity < 3 times/week (SMD 0.68–0.99, p < 0.05), and < 60 min/session (SMD 0.66–0.76, p < 0.01) effectively improved muscle fitness. Resistance training of ≥ 3 sets/session (SMD 0.93–2.90, p < 0.01) and < 10 repetitions/set (SMD 0.93–1.29, p < 0.05) significantly improved muscle fitness. Low-frequency, high-intensity, and short-duration physical activity more effectively improves muscle fitness in children and adolescents. The major limitation of this meta-analysis was the low quality of included studies. The study was registered in PROSPERO with the registration number CRD42020206963 and was funded mainly by the Ministry of Education of Humanities and Social Science project, China.

Chronic Respiratory Diseases

Background: The literature is unclear as to whether children and adolescents with chronic respiratory diseases (CRDs) differ from their healthy peers in physical activity (PA). Objective: To determine the PA levels measured through accelerometers in children and adolescents with CRDs. Methods: The authors conducted a systematic review using five databases. The authors included studies that assessed the PA measured by accelerometers in children and adolescents with CRDs. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. Results: From 11,497 reports returned by the initial search, 29 articles reporting on 4381 patients were included. In the sensitivity analysis, the authors found that children and adolescents with CRDs had a moderate-to-vigorous PA (MVPA) of −0.08 hours per day (95% confidence interval [CI], −0.12 to −0.03 h/d; P = .001), which was lower than the healthy controls; the values for sedentary time (mean difference −0.47 h/d; 95% CI, −1.29 to 0.36 h/d; P = .27) and steps/d (mean difference 361 steps/d; 95% CI −385 to 1707 steps/d; P = .45) were similar for both. Conclusion: Children and adolescents with CRDs have a slight reduction in MVPA in comparison with healthy controls, but sedentary time and steps/d were similar for both.
