Supplementation of 90mg/kg BCAAs (40% valine and 35% leucine) in trained cyclists during submaximal (70-85% VO2 max) cycling exercise was able to reduce perceived physical and mental fatigue without affecting performance parameters significantly (3 subjects had improvement, 4 did not). Fatigue reduction was confirmed by a Stroops word test, and no influence was found on oxygenation uptake or RER (fat oxidation).
