thorough understanding of exercise physiology and the way nutrients support training and competition is essential for the registered dietitian nutritionist working with
active people. Because of the importance of this topic, the first section of Sports Nutrition examines the critical role of macronutrients and micronutrients in exercise performance. Te physiology of exercise includes more than just energy production. Athletic
success depends on proper nutrition for growth and development and for an effective immune system function (Chapter 1). Our knowledge of the interrelated roles of dietary carbohydrate, protein, and fat has increased tremendously in the past decade, and this new information is incorporated into Chapters 2, 3, and 4. Micronutrients are covered in detail in Chapter 5, which presents the most current research on how vitamins and minerals affect sports performance. Te most essential nutrient for athletes, water, is explained in both scientific and practical terms in the chapter on hydration, electrolytes, and exercise (Chapter 6). Lastly, this section concludes with a comprehensive look at dietary supplements and ergogenic aids that athletes use in the hope of improving performance (Chapter 7). Tis chapter discusses how the sports dietitian can critically evaluate dietary supplements and provide sound advice to athletes about using these supplements.
