Figure 2. Pyruvate precursor amino acid concentrations in the tissues and plasma with or without taurine supplementation for 3 weeks or a transient exercise. Amino acid concentrations are shown for A) Threonine, B) Serine, C) Glycine, D) Alanine. Abbreviations: GC-W; white portion of gastrocnemius muscle, GC-R, red portion of gastrocnemius muscle. See the legend of Figure 1 for other abbreviations. Values are shown as the mean ± SD. Differences were analyzed by two-way ANOVA followed by Bonferroni's post-hoc analysis. † with bar, p < 0.05; ‡ with bar, p < 0.01 for the non-supplemented vs. taurine-supplemented groups in the respective conditions. * without bar, p < 0.05; ** without bar, p <0 .01, for the exercised groups versus the respective sedentary group.
