Abbreviations: CAT = catalase; GR = glutathione reductase; GSH = reduced glutathione; GSH-Px = glutathione peroxidase; MDA = malondialdehyde; NTSE = animals receiving no TS but exercised to exhaustion group; NTSNE = animals receiving no TS and no exercise; SOD = superoxide dismutase; T-AOC = total antioxidant capacity; TS = total soy saponins; TSE = animals receiving TS and exercised to exhaustion group; TSNE = animals receiving TS but no exercise group.
