Physical activity, inactivity and their relationship to health are serious concerns for governments around the world. This book critically examines the policy and practice of physical activity from a multi-disciplinary, social-scientific perspective. Moving beyond the usual biophysical and epidemiological approaches, it defines and explores the key themes that are shaping the global physical activity debate. Unrivalled in its scale and scope, it presents the latest data on physical activity from around the world, including case studies from Europe, North and South America, Africa and Asia.
