After doing endurance exercise like running, taking BCAAs seems to help muscles build protein.
Scientific Claim
During recovery from endurance exercise, BCAAs are associated with anabolic effects in human muscle.
Source Excerpt
“Also, during recovery from endurance exercise, BCAAs were found to have anabolic effects in human muscle.”
Evidence from Studies
Supporting Studies
Branched-chain amino acids activate key enzymes in protein synthesis after physical exercise.
The study states that BCAAs have anabolic effects during recovery from endurance exercise. This is a descriptive finding about BCAA effects in endurance exercise recovery.
⚠️ Overstated
The study design is unclear (Level 5 evidence), and the claim uses 'have anabolic effects' which implies causation. The study only shows association between BCAAs and anabolic effects.
More accurate phrasing:
“During recovery from endurance exercise, BCAAs are associated with anabolic effects in human muscle.”
