The team at Case Western Reserve University is studying the effectiveness of playground renovations in increasing physical activity in children and adults. The study will compare ten renovated playgrounds to ten that have not been improved in order to find out if renovations result in sustained increases in physical activity. The researchers are using data collected from the SOPLAY questionnaire, the Environmental Assessment of Public Recreational Spaces inventory tool developed by Dr. Brian Saelens, and statistics from local data sources and the 2000 Census to discover any links between the environment, demographic characteristics, utilization, and activity levels. The researchers will examine whether renovations to playgrounds affects the activity levels of boys, girls, and adults differently.
