Variables presented as mean ± standard error. CT1: concurrent training 5 times per week; CT2: concurrent training 3 times per week. HOMA-IR: homeostasis model of insulin resistance; TBARS: thiobarbituric acid reactive substances; CAT: catalase activity; SOD: superoxide dismutase activity; GPx: glutathione peroxidase activity. < 0.05 (significantly different). Paired -test was utilized to compare before and after training in the same group.
