Publication Title

Nutrition and Enhanced Sports Performance (Second Edition)


Owing to the increased physical demand that results from high volumes of intense exercise training, the daily requirements for energy and carbohydrates and protein are greater in athletes than in sedentary individuals. To date, much research has been published that outlines nutrient intake recommendations for different types athletes, which highlights key differences that occur with gender as well as the modality, intensity, and duration of exercise. Understanding that optimal nutrient composition is important for athletes and coaches because of the impact diet can play on nutrient utilization during exercise as well as in the recovery of exercise. Effective manipulation of these requirements can facilitate and optimize training adaptations while also preventing untoward physiological changes from consuming either too much or too little of the macronutrients. This chapter will present key scientific evidence to outline the optimal nutrient composition for carbohydrates, protein, and fat intake for endurance as well as strength and power athletes.
