Open gym time

Open gym time is offered during the school day to schoolchildren, typically during the lunch period when the gym or multipurpose room is not in use. Shared use agreements can expand open gym opportunities to include community members after school hours and on weekends.

Expected Beneficial Outcomes (Rated)

  • Increased physical activity

Evidence of Effectiveness

Open gym time is a suggested strategy to increase physical activity levels for children and adolescents (CDC MMWR-School health guidelines 2011). Open gym time has been associated with increased physical activity (Mora 2012*, CG-Hoonah Alaska 2012). However, additional evidence is needed to confirm effects.

Open gym time can be implemented as part of a comprehensive school-based physical activity program designed to incorporate additional physical activity opportunities in the school day, or as a standalone effort (Heidorn 2010*). One short-term study of an afterschool program suggests unstructured gym time may increase physical activity more than structured gym time, particularly for boys and students with lower BMIs (McDougall 2016*).

Impact on Disparities

No impact on disparities likely

Implementation Examples

Open gym time during the school lunch period has been implemented in many schools, as in Wake County, NC (WCPSS-Smart lunch) and several cities and towns in Wisconsin (WI DPI-Wagner 2012). In Kearney, Nebraska, the Kearney Public Schools implemented open gym time as part of comprehensive changes to increase student physical activity levels throughout the school day (RWJF-Kearney NE).
