This chapter situates communication within larger schemas of sport group dynamics and then subsequently highlights examples of specific conceptual models of communication. It highlights examples of recommendations for fostering optimal interaction patterns. There have been several approaches to understanding the role of communication within sport teams. In some cases, intra-team communication is noted as a component of larger theoretical frameworks related to the dynamics of sport groups. Understanding the differences in preference for communication allows sport team members to make an effort toward differentiated communication strategies. Intra-team communication is an integral process that influences individual and group outcomes. Conceptual models related to group dynamics, coordination, and teamwork includes communication as a central variable contributing to team effectiveness. Furthermore, researchers have created survey-based and observational methods to capture the communication practices of sport teams.
