Abstract

Objectives: To determine the impact of a one-year physical activity (PA) intervention on changes in school PA opportunities and assess the relationship between changes in school-based PA opportunities and aerobic capacity.

Methods: The multi-level PA intervention was provided to 39 schools in Georgia. Pre- and post- intervention Progressive Aerobic Cardiovascular Endurance Run (PACER) data (a measure of aerobic capacity) were collected for 4th grade students (n=2,342). An online survey was administered to faculty to assess PA opportunities and school setting determinants of PA. Replicated linear regressions were run on changes in school-based PA time to measure the linear correlation with aerobic capacity.

Results: The average number of PACER laps completed increased post-intervention by 2.8 laps, with 73% of children improving or maintaining number of laps completed. Assessment of school opportunities showed 33% of schools increased days/week of recess, 35% of schools increased minutes/day of recess. Over one-third (38%) of teachers reported increased classroom time PA. In addition, 51% of schools adopted a before-school program, 52% of schools increased how often they had access to PA equipment, and increases in multiple types of school wellness initiatives were seen including wellness plans, audio/visual PA information, and school-wide events. Linear regression showed a significant relationship between change in time in school PA and aerobic capacity (r = 0.39, 95% Empirical Interval: 0.31-0.47).

Conclusion: The intervention may be responsible for changes in school opportunities and increased in-school PA, which is directly associated with increases in aerobic capacity. These positive results demonstrate need for further research including large-scale cluster-randomized control trials to assess the full impact of the intervention in a more rigorous setting.
