All values are mean ± SEM; n = 14 (n = 13 for S and S+6AA; n = 12 for W+6AA). Values in the same column with different superscript letters are significantly different, P≤0.05 (ANCOVA followed by Tukey’s multiple comparisons test). S (soy protein isolate); S+5AA (S, iso, leu, lys, thr and val); S+6AA (S+5AA and arg); W (whey protein isolate); W+5AA (W, iso, leu, lys, thr and val); W+6AA (W+5AA and arg).
