There is nothing as practical as a good theory. A good theory explains a phenomenon, predicts relationships and outcomes, is testable (falsifiable), is parsimonious, is generalizable (transferable), and encourages productivity. Physical activity is a complex behavior. Applying theory properly to physical activity will lead to a greater understanding of the important variables and mechanisms involved, guide interventions, and ultimately lead to better public health practices. This chapter presents several theories being used in physical activity in the context of a research article structure. This allows us to describe several theories and to illustrate how theory is part of all aspects of the research process.
