PACE: A group randomised controlled trial to increase children's break-time playground physical activity

Abstract

Introduction: Physical activity provides positive health benefits for children, although many are insufficiently active. The school recess environment offers opportunities for most children to be active. Evidence suggests that environmental and policy changes can increase children's school recess activity levels. The aim of this study was to assess the effect of an intervention that modified the school playground environment and policies addressing physical activity levels among school-aged children during recess.
