Summary
For a muscle to grow (i.e., to hypertrophy), the rate of MPS must exceed the rate of MPB over time. Note that “protein synthesis” refers to the creation of any protein in your body; if your interest lies in muscle growth, you need to focus on MPS specifically.

Do endurance athletes need more protein on rest days?
In this randomized crossover trial in a small group of endurance-trained men, estimated protein requirements were higher on a rest day than a training day.
