IJERPH, Vol. 15, Pages 1764: Moderators of School-Based Physical Activity Interventions on Cardiorespiratory Endurance in Primary School-Aged Children: A Meta-Regression International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15081764 Authors: Ryan D. Burns Timothy A. Brusseau You Fu The purpose of this study was to examine potential moderators of school-based physical activity interventions on cardiorespiratory endurance in primary school-aged children using meta-regression. An Internet search with several databases was employed, extracting school-based pediatric physical activity intervention studies published within the past 30 years. Studies were included if there was a control or comparison group, if the study sample included primary school-aged children, if the targeted outcome of cardiorespiratory endurance was objectively assessed, if the intervention was at least partially school-based, and if the effect estimate’s variability was reported. An inverse-variance random effects meta-regression was employed using the primary predictors of component number (single component or multi-component) and intervention length using 20 extracted studies with 23 total effects. The overall pooled effect on cardiorespiratory endurance was statistically significant (Hedges’ g = 0.30, 95% C.I.: 0.19–0.40; p < 0.001). Using random effects meta-regression, neither component number (b = –0.09, 95% C.I.: –0.40–0.23; p = 0.560) ...
