The assignment for the 76th Annual Meeting of the American Academy of Kinesiology and Physical Education was to define the psychology subdiscipline of kinesiology. Ten undergraduate sport and exercise psychology textbooks, 27 undergraduate course syllabi, and three articles which examined the most popular contents of prominent journals were analyzed. Similar topics were found across all avenues of research, and are deemed important. Throughout our investigation we noted a lack of cross-disciplinary integration. We review the issue of separatism across subdisciplines of kinesiology, and suggest a cross-disciplinary focus in the texts, research, and the classroom. Finally, we discuss the issue of choosing appropriate names to represent our field, and propose that the name physical activity should be adopted. (Contains 2 tables and 3 figures.)
