Dietary protein for athletic populations serves as a signal and substrate for muscle protein synthesis (MPS), aiding in hypertrophy, repair of damaged proteins, and maintenance of lean mass.
Athletes should focus on protein intake to enhance muscle growth and recovery.
StrongSupportsmedium confidence
Dietary protein for athletic populations can serve as signal and substrate for MPS, resulting in protein accretion for hypertrophy, repair of damaged proteins or assisting the maintenance of lean mass.
Why this rating
The claim is supported by established research on protein's role in muscle physiology.

- Skeletal muscle protein turnover rates are approximately 1%–2% per day, with muscle protein breakdown (MPB) exceeding muscle protein synthesis (MPS) in the fasted state, and MPS exceeding MPB in response to protein-containing meals.Strong
- Adults generally need no more than 0.8–0.9 g/kg/d of protein to meet their needs.Strong

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
