In our study, although we observed a reduction in BAP levels after training, the evaluation of SOD, CAT, and GPx activity did not reveal significant differences between pre- and postexercise values. This could be explained by the fact that the enzymatic antioxidants are mainly present intracellularly, while nonenzymatic antioxidants prevail at extracellular level. Indeed, it has been shown that, in condition of strenuous and continuous training, variations of antioxidant parameters are different. As example, erythrocyte SOD, GSH-Px activities, and blood GSH were shown to be unchanged, while plasma total antioxidant status was decreased, and plasma GSH-Px activity increase failed to prevent oxidative exercise-induced damage in overloaded triathletes . This suggests nonsynergistic responses in antioxidant parameters during OT (even if some parameters eventually adapt, it may be insufficient to prevent oxidative damage).
