Final answer:
A high-carbohydrate diet increases the rate of amino acid utilization during prolonged exercise.
Step-by-step explanation:
A high-carbohydrate diet increases the rate of amino acid utilization during prolonged exercise.
Carbohydrates are an important fuel source for the brain and muscles during exercise. When carbohydrates are consumed, they are broken down and converted into glucose, which is used by the body as a source of energy. During prolonged exercise, the body relies heavily on carbohydrates and glycogen stores to meet its energy demands. As a result, the rate of amino acid utilization increases.
