ABSTRACT
This part introduction presents an overview of the key concepts discussed in the subsequent chapters. The part focuses on the way in which biomedical evidence has been interpreted to inform one of the most foundational elements of physical activity policy worldwide, guideline recommendations for physical activity participation. It explores the audiences for such guidelines; Weed contends that, regardless of intention, physical activity guidelines are direct public health interventions. The part argues that physical activity policy suffers from a failure to consider social science evidence. It also argues that physical activity guidelines do not consider evidence about the structural causes of health inequalities and the ways in which people's health can be constrained by their social situation, instead focusing solely on individual responsibility to adopt healthy behaviours. The part considers how far physical activity policies based on individual responsibility can go in supporting people's motivation and self-efficacy, and opportunities that exist for social support.
