Impact of an Elementary School-Based Intervention on Physical Activity Time and Aerobic Capacity, Georgia, 2013-2014:

Objectives:The objectives of this study were to (1) determine the impact of a 1-year elementary school physical activity intervention on changes in teacher-reported school-based physical activity time and (2) assess the relationship between these changes and changes in student aerobic capacity.Methods:HealthMPowers, a nonprofit organization, provided a multicomponent physical activity intervention to 3479 students in 39 schools in Georgia during 2013-2014. HealthMPowers administered a survey to faculty members before (August 2013) and after (May 2014) the intervention to measure student physical activity times. The organization collected pre- and post-intervention Progressive Aerobic Cardiovascular Endurance Run (PACER) laps (a measure of aerobic capacity that awards 1 lap for each completed 20-meter lap) for 2342 fourth-grade students. We performed linear regression to determine the relationship between school-level changes in teacher-reported school-based physical activity time and student aerobic capac...
