Complex Assessment of the Blood Oxidative Metabolism in Qualified Athletes

Abstract

The purpose of this research was to study the structure of the shifts in the blood oxidative metabolism in professional athletes. Materials and Methods: The study included 262 highly qualified athletes (Group 1) aged between 19 and 29 years. The control group (Group 2) consisted of healthy untrained volunteers of similar age. In blood plasma, we estimated the levels of 8-isoprostane, ox-LDL, alpha- and beta-carotene, alpha- and gamma-tocopherols, and tissue-specific antioxidants (lycopine, luteine and zeaxantine) and the activity of superoxide dismutase and glutathione peroxidase. Results: Thus, in qualified athletes, characteristic changes in the state of oxidative metabolism, concerning the components of the pro- and antioxidant systems, were determined; however, the inhomogeneity of these metabolic transformations attracts attention. The revealed regularity allows confirming the previously stated hypothesis about the heterogeneity of shifts in oxidative metabolism in professional athletes, which suggests different approaches to their correction.
