Are Gross Motor Skill Interventions an Equitable Replacement for Outdoor Free Play Regarding Children's Physical Activity?

Purpose: The purpose of this study was to determine if children engaged in equal amounts of physical activity during an established gross motor skill intervention (the Children's Health Activity Motor Program (CHAMP)) and outdoor free play.

Design: Cross-sectional study; sample: Ninety-nine children (Mage = 4.21, 51% boys) were randomly divided into two movement environments: CHAMP (n = 55) or control/outdoor free play (n = 44).
