Muscle protein synthesis is the process that the human body uses to repair, grow, and strengthen muscle fibres. Muscle protein breakdown (MPB) gets a bad rap but is a crucial process in building muscle and when suppressed in rodents we see that they are actually smaller and weaker. That being said, we want the balance of MPS and MPB to favour MPS, this is how we ensure that more muscle is built than broken down. The best ways to increase MPS are to do heavy strength training, eat enough calories and protein, and time feedings of 30-40g of protein every 3-4 hours.
