Prolonged exercise (> 2 hours) can lead to increased breakdown of muscle protein and release of amino acids into the pool, thus enhancing protein metabolism in the muscle. This is because during extended periods of exercise, the body may start to utilize amino acids as an energy source once glycogen stores are depleted.
