• Resumen

  • The present study tested the effect of a school-based physical activity (PA) program on quality of life (QoL) in 540 elementary school children. First and fifth graders were randomly assigned to a PA program or a no-PA control condition during one academic year. QoL was assessed by the Child Health Questionnaire at baseline and postintervention. Based on mixed linear model analyses, physical QoL in first graders and physical and psychosocial QoL in fifth graders were not affected by the intervention. In first graders, the PA intervention had a positive impact on psychosocial QoL (effect size [d], 0.32; p < .05). Subpopulation analyses revealedthat this effect was caused by an effect in urban (effect size [d], 0.38; p < .05) andoverweight first graders (effect size [d], 0.45; p < .05). In conclusion, a school-basedPA intervention had little effect on QoL in elementary school children.
