Cognitively engaging movement games improve interference control and academic performance in overweight children: A randomized control trial.

The purpose of this study was to determine the (a) dose–response effects of cognitively engaging movement games (CEMGs) designed to improve aerobic capacity, interference control (IC), and academic performance, (b) relationship between intervention‐induced improvements in aerobic capacity, IC, and academic performance, and (c) moderation effect of IC on the relationship between aerobic capacity and academic performance in overweight children. Seventy‐five overweight children (aged 11.23 ± 0.60 years; 48% males) participated in this study conducted in Taipei during the 2018/2019 academic year and were randomly assigned to the low‐dose (20‐min) intervention, high‐dose (40‐min) intervention, and control groups and completed a Stroop test, half‐mile run, and language and mathematics tests before and after a 10‐week afterschool program. Both intervention groups showed similar improvements in outcomes of aerobic capacity (ds > 0.80), IC (ds > 0.76), and academic performance (ds > 0.90) from the pretest to posttest, whereas these outcomes were unchanged for the control group. Furthermore, improved IC moderated the association between improvements in aerobic capacity and academic performance. Our findings suggest that CEMG with varying doses is feasible and effective for improving aerobic capacity, IC, and academic performance in overweight children and that the association between improvements in aerobic capacity and academic performance depends on the intervention effects on IC.
