Group Dynamics in Sport, 5th edition, provides readers with the most current theory and practice of group dynamics in sport teams. With updated chapters, this upcoming edition features four sections that explore the study of group dynamics in an engaging and friendly manner. Each chapter offers current and classic examples to illustrate the principles covered while also summarizing key theoretical concepts in an accessible way. Material covered includes an analysis of the nature, study, and development of groups; foundational elements of the group including member attributes and the group’s environment; structural elements including group positions, roles, norms, and status; as well as group processes and emergent states such as leadership, communication, cohesion, collective efficacy, and team building. The text stresses the theoretical significance of studying groups to gain a richer understanding of human nature, as well as the importance of application to real life by linking concepts to elite sport examples and practical strategies to enhance groups. As the formative text for studying sport group dynamics, Group Dynamics in Sport, 5th edition, is an invaluable introductory resource for undergraduate and graduate students, researchers, and practitioners interested in better understanding how groups work.
