title: Where do the children play? The influence of playground equipment on physical activity of children in free play.
abstract: BACKGROUND
  Promotion of physical activity in children depends on an understanding of how children use play equipment.
  
  
  METHODS
  We conducted observations over 2 years of children in 2nd through 8th grades in a schoolyard with 5 distinct play areas with different amounts of play equipment.
  
  
  RESULTS
  Children were more likely to play in areas with more installed play equipment, with densities of children in equipped areas 3.3 to 12.6 times higher than in an open grassy field. There were no significant differences by play area in the percent of children who were physically active at all, but children were more likely to be very active in areas with basketball goals and an installed play structure than in an open field.
  
  
  CONCLUSIONS
  Playground equipment appeared to have a strong influence on where children played and a moderate influence on levels of activity. To maximize physical activity in children, playgrounds should be designed with ample and diverse play equipment.
