Muscle Protein Synthesis

Muscle Protein Synthesis (MPS) is a process that repairs muscle damage caused by intense exercise and activity. It repairs and strengthens the muscle fibers. Amino acids are the key, responsible for creation/repair of muscle tissues. There are two ways MPS can be activated : Nutrition and Exercise. Nutrient-driven increases in MPS are of finite duration. So even if there are sufficient amount on amino acids available, the MPS is not prolonged. With resistance training though, the MPS can be even beyond 24 hours after a single exercise session.(1) Muscle Protein Balance decides if you gain or lose muscles. It is the difference between Muscle Protein Synthesis (MPS) and Muscle Protein Breakdown (MPB). When the MPS is more than the MPB, you see an increase in net muscle mass. When you see MPS is less than MPB than you lose muscle mass. And If both MPS and MPB are equal, then muscle mass will remain maintained. 1.Atherton, P. J., & Smith, K. (2012).
