Muscle Protein Synthesis (MPS)
The process by which the body builds new muscle protein, stimulated by resistance training and protein intake.
Muscle Protein Synthesis is the cellular process of building new contractile proteins — the adaptation that grows muscle. MPS is stimulated for 24–72 hours after a resistance training session and is maximized by consuming ~30–40 g of high-quality protein per meal, spread across 3–5 meals per day. Leucine is the primary amino-acid trigger; ~2.5 g of leucine per meal saturates the response in most adults.
