PC: protein carbonyls; TBARS: thiobarbituric acid reactive substances (malondialdehyde measured spectrophotometrically); TAC: total antioxidant capacity; GSH: reduced glutathione; CAT: catalase; sORP: static oxidation-reduction potential; cORP: capacity oxidation-reduction potential; SRS: superoxide radical scavenging; HRS: hydroxyl radical scavenging; RP: reducing power; MDA: malondialdehyde (measured by HPLC-DAD). Values are expressed as mean ± SEM. Statistically significant compared with preexercise values (). Statistically significant between trained and untrained at the same time point.
