Contrast the protein requirements for an endurance athlete to requirements for a strength-trained athlete.

What will be an ideal response?


Although amino acids derived from protein can fuel muscles, their contribution is relatively small compared with that of carbohydrate and fat. As a rough guide, only about 5% of the body's general energy needs, as well as the typical energy needs of exercising muscles, is supplied by amino acid metabolism. However, proteins can contribute to energy needs in endurance exercise, perhaps as much as 15%, especially as glycogen stores in the muscle are exhausted. Endurance exercise is when protein is most likely to make its most significant contribution as a fuel source-but, even then, it provides limited energy, with estimates ranging from 3 to 15%. In contrast, protein is used least in resistance exercise (e.g., weight lifting)
