Muscle volume decreased in the injured muscle compared to the contralateral healthy muscle during the intervention by −9.4% (−13.5% to −5.3%), p < 0.0001, and this decrease persisted at 12 months.
Rehabilitation programs should consider the persistent loss of muscle volume after strain injuries.

- 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
