- 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.Strong
- There was a persistent increase in aponeurosis volume associated with the injured muscle at 3 months and 12 months, but it was unaffected by protein supplementation.Strong
