Purpose: To evaluate the effectiveness of game-based approaches on game performance, fundamental movement skills, health-related indicators, and physical activity outcomes among children (5-12 years) when delivered in the primary physical education school setting. Method: A systematic search of six electronic databases without date limitation was conducted on June 11, 2021. Results: Among included studies (N = 17), positive outcomes were found for children's game performance, fundamental movement skills, physical and mental health, and/or physical activity. Game-based approaches intervention success appears to be related to the contents of teacher training, especially the inclusion of a theory-based syllabus, mentoring, and reflection sessions. Conclusions: The findings of this review confirm that hybrid sport education-invasion games interventions delivered in primary schools are beneficial for improving a range of student outcomes. To improve physical self-perception, intrinsic motivation, well-being, physiological, and potential psychological outcomes for children, it is necessary to explore more game-based approaches' longitudinal and intervention research with high quality.

Background: Few mobile health resistance-based physical activity interventions have targeted community-dwelling adults. "Ecofit" is a multicomponent intervention that promotes resistance and aerobic activities using smartphone technology, outdoor gyms, and social support. This study evaluated process evaluation outcomes of the ecofit randomized controlled trial: (1) the acceptability and usability of the ecofit smartphone app and app user workouts; (2) perceptions of factors influencing outdoor gym use; and (3) the fidelity, reach, recruitment, and dose received of the ecofit program. Methods: Process data were collected through program evaluation surveys at 3 months, and app usage data were collected via the intervention platform for up to 3 months. Data were analyzed using descriptive statistics. Results: The survey was completed by 57% (n = 69) of eligible participants. The majority (93%) believed the app provided them with sufficient information to perform muscle-strengthening activities. Approximately half (51%) agreed that the goal-setting function encouraged them to complete their workouts, and 42% agreed that the self-assessment helped them monitor progress. "Proximity" to outdoor gyms emerged as the most important factor for choosing locations to workout (mean = 5.5, SD = 1.1). Participants logged a median of 5.5 (interquartile range = 19) workouts and 1 (interquartile range = 1) upper- and lower-body muscular fitness self-assessment. Conclusions: The ecofit app provided participants with sufficient skills to perform unsupervised resistance training exercises using mobile health. Only half of the participants regarded self-assessments and goal setting as useful, suggesting a need for modifications to how these are implemented. Mobile health remains a promising delivery platform to promote unsupervised resistance training, although more research is needed to improve uptake. [ABSTRACT FROM AUTHOR]

There is growing interest in identifying the mechanisms underpinning the effects of physical activity on executive functions (e.g. inhibitory control, cognitive flexibility) in children. Our study examined cardiorespiratory fitness, muscular fitness, and motor competence as potential mediators of this relationship. The study used baseline data from the Learning to Lead (L2L) cluster randomised controlled trial. In total, 675 children (7–11 years, 49.5% girls) completed measures of moderate-to-vigorous physical activity (MVPA), cardiorespiratory fitness, muscular fitness, motor competence, and executive functions. Structural equation modelling was used to examine the potential mediating roles of cardiorespiratory fitness, muscular fitness, and motor competence in the cross-sectional association between MVPA and executive functions. Cardiorespiratory fitness (β = 0.06, SE = 0.021, p = 0.004) partially mediated the association between MVPA and cognitive flexibility. Muscular fitness was a significant mediator of the association between MVPA and both inhibitory control (β = 0.03, SE = 0.014, p = 0.027) and cognitive flexibility (β = 0.06, SE = 0.021, p = 0.005). No significant mediated effects were found for motor competence. Our findings suggest cardiorespiratory and muscular fitness (but not motor competence) mediate the association between physical activity and executive functions in children. [ABSTRACT FROM AUTHOR]

Introduction: Secondary schools have the potential to promote health-related fitness (HRF) and physical activity within and outside school hours. As such, schools are often chosen as the setting to implement child and adolescent physical activity programs. School-based programs often utilise teachers as delivery agents, but few studies examine effects on teacher-level outcomes. Purpose: The primary aim of this study was to determine the impact of teacher training embedded within a physical activity intervention on teacher-level outcomes. The secondary aim of this study was to evaluate process data, including implementation, satisfaction and fidelity. Methods: "Resistance Training for Teens" ("RT for Teens") was evaluated using a cluster randomised controlled trial in 16 secondary schools. Teachers (N = 44; 48% female/52% male; mean ± SD years teaching experience = 10.6 ± 8.0) from 16 secondary schools were assessed at baseline. Intervention group teachers (i.e. from eight schools) delivered a structured school-based physical activity program over 10-weeks. Teacher outcomes included confidence to teach health-related fitness (HRF) activities, perceived barriers to teaching HRF activities, and perceived fitness. Detailed process evaluation data were also collected. Assessments were conducted at baseline and 6-months (post-program), and outcomes were assessed using repeated measures analysis of variance. Results: There was a positive group-by-time effect for the confidence composite score (p = 0.010, partial eta squared = 0.29), but no effects for the two (contextual, interpersonal) barrier composite scores. Also, there was a significant effect for perceived 'general fitness' (p = 0.044, partial eta squared = 0.13), but not for specific fitness subdomains. Teachers were highly satisfied with both the training and the program, believing it was beneficial for students. Resource usage and adherence to the SAAFE (Supportive, Active, Autonomous, Fair, Enjoyable) delivery principles was high. Conclusion: "RT for Teens" improved teachers' confidence and perceived fitness. These findings highlight the potential for high-quality teacher training and program delivery to positively influence teacher-level outcomes. This may provide support for the use of teacher professional development to improve HRF-related pedagogy.

Introduction: This study set out to understand the association between teaching practices, teacher confidence, competence, self-efficacy, and the resulting student outcomes. Methods: Data regarding teaching behaviours were collected via video recording and then evaluated using the MASTER Observation Tool. The information about demographics, self-reported teaching confidence, competence, self-efficacy, and student outcomes was collected using questionnaires. The association between teacher characteristics, and teacher and/or student outcome variables were tested using a one-way analysis of variance (ANOVA). Results: A total of ten primary schools were involved, including 597 children (age range: 10-12 years, grade 4-6) and 16 grade 4-6 PE teachers (with 16 PE classes). Most of the Physical Education (PE) lesson time was spent in training-form activities (60.2% ± 9.1), followed by instructional time (33.1%± 8.6%), reflection (3.4%± 2.3%), and warm-up (2.9% ± 2.0%). It was observed that teaching behaviours and student outcomes were significantly better in urban than rural areas. Smaller class sizes (21-30 children) were found to have more positive feedback than larger ones (41-50 children). PE teachers with more than 10 years of teaching experience reported more teaching competence and selfefficacy than teachers with less than 10 years of experience. PE teachers with class sizes of 21-30 children enjoyed significantly better scores in self-efficacy than classes with 41-50 children. They also scored more highly in confidence and competence than classes with 41-50 and 51-60 pupils. Conclusion: The current study confirmed that teachers dedicated a large proportion of lesson time to PE delivering training-form activities, followed by instructional time. Teaching behaviour and student outcomes were associated with location and class size, but not gender. The study contributes to our understanding of PE instruction in Chinese primary schools and offers preliminary evidence to improve future PE teaching strategies in the country.

Background: The COVID-19 global pandemic greatly impacted lifestyles and physical activity routines. This study explored how the COVID-19 pandemic impacted participant experience and motivation in ecofit, a large, community-based, multicomponent intervention that supports aerobic and resistance-based physical activity using publicly available, outdoor exercise facilities and smartphone technology. Methods: Fifteen participants from the intervention arm of the study were interviewed. Audiotaped telephone interviews were transcribed verbatim and analyzed by a researcher uninvolved in the intervention. Through an inductive thematic approach, data were coded and organized into themes. The quantitative measure of participant smartphone application engagement was used as a classification during analysis. Results: Several themes representing participants' experience of the COVID-19 pandemic in their engagement with ecofit, overall physical activity levels, motivation to exercise, and perception and usage of outdoor gym facilities were identified. Conclusion: The impact of the COVID-19 pandemic on clinical trials is beginning to emerge. Although the present study showed a mixed impact of the pandemic on participation in the ecofit program, the overall implications for the intervention are yet to be determined. Interestingly, although a large review found a negative impact of COVID-19 on physical activity, this sample reported an overall increase. [ABSTRACT FROM AUTHOR]

Organized sport is a context in which to promote positive youth development (PYD). Interventions with a PYD lens are often implemented to promote a wide range of physical or psychosocial benefits through sport participation. To date, no meta-analytic review of the effect of these interventions has been conducted. This is important because such interventions are held in high regard when it comes to policy development. In the present study, we conducted seven meta-analyses to evaluate the overall effect of sport-based interventions on PYD outcomes. Aspects of the study design and sample also were tested as moderators. In total, 35 studies (from 29 published articles) reporting on 74 effect sizes highlighted small to medium effects of PYD interventions on competence, confidence, and life skills outcomes. No significant overall effects were found for outcomes related to character, connection, PYD climate, and health. Further, moderation analyses showed that: (a) character was moderated by study design, sport type, and study duration; (b) competence was moderated by design and participant sex; and, (c) life skills were moderated by design, sport type, duration, and participant age. Implications for theory and practice concerning the use of sport-based interventions to influence PYD are discussed. [ABSTRACT FROM AUTHOR]
