The unifying theory of physical activity

This article offers a governing, trans-disciplinary theory for understanding physical activity in humans. The Unifying Theory of Physical Activity involves three aspects. First, it frames physical activity as an essential human act resulting from inherent urges: to feel, to explore, to transform and to connect. These urges prelude and compel people's involvement in physical activity and contribute to the meanings and purposes that sustain life and growth. Second, we argue the act of physical activity is made of three conditions. Physical activity possesses a potentiality, and it is distinct and integrated. Third, at the external level, there are social, political, and situated forces that interplay with the urges and shape human experience in/of physical activity. We offer conclusions about how this theory can inform research, policy, and practice about physical education, physical activity and health promotion.
