Muscle Protein Synthesis (MPS)

"The biological process of building new muscle tissue from dietary protein."

Definition

The full breakdown. What it is, why it matters, how to use it.

Muscle protein synthesis is the process by which the body assembles new muscle proteins. It's elevated for 24–48 hours after a hard training session and is triggered each meal by ~2.5–3g of leucine. Net muscle growth occurs when MPS exceeds muscle protein breakdown over time.

How many protein feedings per day for MPS?

3–5 meals of 30–50g of complete protein each, spaced 3–5 hours apart, maximize 24-hour MPS.
