Fig. 10From: Effects of a commercially available branched-chain amino acid-alanine-carbohydrate-based sports supplement on perceived exertion and performance in high intensity endurance cycling testsFree Trp to BCAA ratios. Free Trp and BCAA levels were determined and their ratios were then calculated in both the FP and PL groups. Trp:BCAA ratios before (pre-HIEC) and after HIEC test (post-HIEC) are shown. Panel a shows analyses performed at 1d and panel b those performed at 9w. Values for the SU (black bars) and PL (white bars) groups are reported as means with standard deviations. * p < 0.05 between groups; # p < 0.05 between time pointsBack to article page
