ABSTRACT

Public health researchers in the United States have recognised the economic and societal cost of physical inactivity as a primary risk factor for chronic degenerative disease. The problem of physical inactivity is a complex one, however, with multiple biological, social and environmental determinants that interact across levels of influence. From an ecological perspective, it is important to recognise the critical role that policy plays at both the national and local levels. This chapter provides insight into physical activity policy efforts in the United States at the national (Physical Activity Guidelines for Americans and U.S. National Physical Activity Plan) and state levels (West Virginia Physical Activity Plan). Specific policies described include those targeting school physical education and physical activity, safety and active transportation, and promotion of shared-use of public facilities through limited liability.
