The present study investigated the hypothesis that single-sprint anaerobic exercise affect redox reaction system in plasma by measuring the concentration of total reactive oxygen metabolites and the plasma biological antioxidant potential (BAP). Seventeen young, healthy males (20.7±1.2 years) participated in this study. We measured the plasma hydroperoxide concentration and the plasma BAP before, immediately after, and at 30 minutes after Wingate anaerobic test (WAnT). Maximal power and peak revolutions per minute, which indicate anaerobic power, were recorded during the WAnT. The plasma hydroperoxide concentration immediately after the WAnT was significantly higher than at rest (P<0.001). The plasma BAP immediately after the WAnT was significantly higher than at rest (P<0.001). Both the plasma hydroperoxide concentration and the plasma BAP were not significant difference between at rest and at 30 minutes after the WAnT. No significant relationship was found between the plasma hydroperoxide concentration and the plasma BAP at rest, immediately after and at 30 minutes after the WAnT. Furthermore, no relationship was found between the plasma hydroperoxide concentration, the plasma BAP and the anaerobic power. These findings suggest that the single-sprint anaerobic exercise induces oxidative stress and that BAP increased in conjunction with increases in plasma hydroperoxides. It seems likely that variability in oxidative stress and the antioxidative potential at rest might be responsible for the elevated hydroperoxide production during exercise and the elimination of hydroperoxides by the plasma BAP. The results indicate that the anaerobic power is hardly affected by the oxidative stress status.
