Note: By S-N-K test of a 1-way ANOVA: ^ap < 0.05, ^bp < 0.01, compared with the control group; ^cp < 0.01, compared with the exhausted group; ^dp < 0.01, compared with the TS group.

Abbreviations: CAT = catalase; GR = glutathione reductase; GSH = reduced glutathione; GSH-Px = glutathione peroxidase; MDA = malondialdehyde; SOD = superoxide dismutase; T-AOC = total antioxidant capacity; TS = total soy saponins.
