This text is structured in two parts. The first analyses the science that underpins the nutritional goals of athletes, with a focus on the implications for athletes during training, competition and recovery. The second looks more closely at the practical implications for different sport categories, i.e. those that focus on strength, power or endurance, and on weight category sports, team sports and winter sports. This volume will be of value to sports dieticians and nutritionists and others involved in the care and support of athletes.
