Enhancing the Translation of Physical Activity Interventions in Afterschool Programs

Afterschool programs (3-6 PM, ASPs) represent a promising approach to promote physical activity (PA) and are positioned to make a substantial contribution to children's overall daily PA. This article synthesizes both descriptive and intervention focused efforts aimed at describing/increasing PA within the ASP setting and outlines future directions for research. ASPs provide anywhere from 8 to 24 minutes of moderate-to-vigorous PA daily, with children accumulating between 2600 and 3200 steps per day. State and national organizations have developed policies related to PA in ASPs, but the limited available evidence indicates that ASPs are far from meeting PA policy goals. A total of 17 ASP PA intervention studies have been conducted, more than half (9/17) within ASPs that were initiated and developed by researchers. Based on the review of evidence, key strategies to increase PA include high-quality professional development training, allocating time in the ASP schedule for children to engage in sufficient amounts of PA, and tailoring the intervention to local conditions. Future directions should focus on evaluating these key strategies, conducting descriptive studies of common ASP characteristics nationally and their influence on children's PA, evaluation/refinement of existing ASP PA curricula, cost-effectiveness of interventions, and identification of feasible PA policy goals.
