The interaction between the BCAAs and Arg tended to influence the concentrations of IgA ( P = 0.059) and IgG ( P = 0.069), and the orthogonal contrast between the BCAA and the Control groups showed a trend to a higher concentration of IgA in the BCAA group as compared with the control group ( P = 0.09) while the other contrasts regarding IgG were not significant.
