Kaphingst and Story (2009) reported the regulations of all 50 U.S. states as they relate to physical activity promotion. The initial assessment of physical activity policies were conducted in 2006. Findings varied by setting (i.e. child care center, small family child care home, large family or group child care home). The requirements assessed included, activity programs engaging large muscle groups (19-39 states), daily outdoor activity time (24-36 states), quantified physical activity time requirements (2 states), and physical activity intensity requirements (2-10 states). These data can be used as a benchmark to assess physical activity policies enacted at the state level.
