Group Dynamics in Exercise and Sport Psychology explores the unique psychological dynamics that emerge in sport and exercise groups. It provides a clear and thorough guide to contemporary theory, research, and applied practice, covering core themes and cutting-edge topics as well as highlighting directions for future research. Much human behaviour in sport and exercise settings is embedded within groups, where individuals’ cognitions, emotions, and behaviours influence and are influenced by other group members. Now in a fully revised and updated third edition, Group Dynamics in Exercise and Sport Psychology sheds new light on the psychology of groups in exercise and sport settings, providing an entirely new set of perspectives on the theory and research applied to groups in exercise and sport settings. No other book on group dynamics in sport or exercise offers such a close examination of the evidence base, and therefore Group Dynamics in Exercise and Sport Psychology is important reading for all students, researchers, or practitioners working in sport or exercise psychology, kinesiology, sport and exercise science, sports coaching, or physical education.
