Success in high performance sport is highly valued in today’s world, with lucrative contracts, sponsorship deals, and opportunities for celebrity status balanced against substantial investments of time and energy, and high chances of failure. With pressure mounting on athletes and coaches to make the most of athletic investments, the temptation to make health-related or ethical compromises is growing. Sustainability in High Performance Sport examines the pressures faced by coaches and athletes, and considers how sustainable science can offer alternative pathways to sporting excellence. By applying principles relating to carrying capacities, complexity and uncertainty, production and consumption, and ethics, this unique book provides new ways of thinking about both enduring and emerging challenges. With a scope that includes themes such as coaching practices, coach-athlete relationships, over-training and injuries, the development of sporting expertise, and doping, Sustainability in High Performance Sport is the most comprehensive exploration of sustainability in elite sport available. It is an invaluable resource for anybody with an interest in achieving long-term success in high performance sport. This book was originally published as a special issue of Reflective Practice.
