The Center for Physical Activity and Health (CPAH) was founded in 2004 and is a collaboration between the Michigan State University Department of Kinesiology in the College of Education and the Department of Epidemiology in the College of Human Medicine. The mission of CPAH is to study the effect of physical activity on human health and well-being throughout the life span. Our aim is to position MSU as a leader for impacting the lives of Michigan and U.S. citizens in terms of appropriate physical activity intervention strategies.
