Sport is increasingly being described as a complex system. This inherent complexity cannot be understood by examining components in isolation; rather, the system as a whole should represent the unit of analysis. Systems thinking is the answer to understanding this complexity and is gaining traction in sport. Systems thinking provides a philosophy and a set of associated methods which can be used to understand and optimise the behaviour of complex systems, such as those inherent within sport.This book presents, for the first time, a practical guide to applying contemporary systems thinking methods in sport as well as case study applications demonstrating how their outputs can be translated in practice. The methods described in this book can be used for better understanding the systemic influences in a broad range of sport contexts, including performance, injury, team functioning, decision making, adverse incidents, sports organisation design and redesign, technology implementation, and proactive risk assessments.Systems Thinking Methods in Sport provides a practical step by step guide for sports practitioners and stakeholders, as well as university students and academics in applying state of the art systems thinking methods to sport.
