Values at each time point are mean ± standard deviation. Δ% was calculated from raw group means as [(week 8 – baseline) / baseline] × 100. Model estimates are week 8 difference-in-differences versus control from linear mixed-effects models including group, time, and group × time, with participant as a random intercept. Positive model estimates indicate a greater increase than control. Holm p values were adjusted across the intervention-versus-control contrasts in the physical-fitness family. Hedges’ g is the standardized between-group difference in baseline-to-week 8 change versus control. SSG = small-sided games; CI = confidence interval.
