ABSTRACT
Exercise psychology has emerged as a field of study on the basis of a steadily building wave of research conducted over the past 30 years. The study of physical activity and psychological constructs is a relatively new discipline that has its roots appropriately in the fields of other more established disciplines such as sport psychology, social psychology, and epidemiology. Exercise psychology is a vastly broad topic encompassing an array of disciplines, professions, and fields of study, including interdisciplinary collaborations and networks. A primary mission of exercise psychology research is to understand why people do or do not choose to be physically active under varying circumstances, and what factors might be altered to get people to make active choices. A task in the field of exercise psychology is the development of theoretical models to analyse exercise conditions.
