This book deals principally with the relationships between diet, fitness, and physical work capacity. The extreme nutritional states of obesity and chronic food deprivation are considered, and the effect of supplementation and modification of normal dietaries on work capacity are discussed. Figures and data tables provide information regarding these nutritional states and their effect on treadmill exercise or comparable stress tests. Topics also addressed include minimum feeding concepts, performance and body composition, insulin mechanisms, sports medicine, and sports management as it relates to athletic nutrition. (JD)
