Understanding how exercise and dietary protein alter the turnover and synthesis of body proteins in youth can provide guidelines for the optimal development of lean mass. This review hypothesizes that active youth obtain similar anabolic benefits from exercise and dietary protein as adults, but the requirement for amino acids to support growth renders them more sensitive to these nutrients.

The anabolic effect of exercise and dietary protein is greater in active youth than in adults.
