What the study found
Adding branched-chain amino acids changed blood amino-acid measures but did not improve exercise, cognition, mood or perceived exertion compared with carbohydrate alone.
Participants and protocol
Seven heat-acclimated men completed two trials after experimentally induced glycogen depletion and hypohydration, exercising in a hot chamber with energy-matched drinks.
What this cannot establish
The preparation was deliberately stressful and is not a routine to reproduce. The findings do not establish benefits in hydrated athletes or justify dehydration or supplement use.
