ABSTRACT
In the human body, much of the dry weight (the body mass minus body water) consists of proteins. Proteins are involved in all aspects of life and are found in every cell of the body; they are needed to promote growth and to repair damaged cells and tissues. In comparison with carbohydrates and fats, protein plays a different role in an athlete’s diet. The primary role for carbohydrates in relation to training is to provide energy for high-intensity activities (such as sprinting, high-intensity endurance exercise, and resistance exercise). The primary role for dietary fat in relation to training is also to provide energy. However, fat primarily fuels lower intensity exercise and is also the primary fuel utilized during recovery (in the hours after exercise and during the rest periods between sets in a traditional resistance-exercise workout) and at rest.
