Most Americans are not sufficiently physically active, even though regular physical activity improves health and reduces the risk of many chronic diseases. Those living in rural, non-White, and lower-income communities often have insufficient access to places to be active, which can contribute to their lower level of physical activity. The shared use of school recreational facilities can provide safe and affordable places for communities. Studies suggest that challenges to shared use include additional cost, liability protection, communication among constituencies interested in sharing space, and decision-making about scheduling and space allocation. This American Heart Association policy statement has provided recommendations for federal, state, and local decision-makers to support and expand opportunities for physical activity in communities through the shared use of school spaces.
