The purpose of the study was to explain whether application of a single dose of -tocopherol could reduce oxidative damage in proteins and lipids in blood of the soccer players who performed a submaximal physical exercise as well as whether there is a relationship between muscle damage and oxidative stress. The research was carried out on 22 students of the coaching studies who participated in a sparring soccer match. The athletes were divided into two groups: control (cod-liver oil) and a group supplemented with vitamin E (800 mg) 2 h before the exercise. In the blood plasma levels carbonyl groups, lipid peroxidation products (TBARS), -glucuronidase (G) and creatine kinase (CK) were estimated. The obtained data showed significant (p<0.05) increase in carbonyl groups concentration after the second half of the game; 30 min later it returned to the pre- exercise values. The TBARS concentration increased after the first and second halves of the game and maintained the high level till 30 min of rest. After 24 h rest the TBARS concentration in the supplemented group was significantly lower in comparison with the control group. The G activity increased (p<0.05) after the second half of the game, whereas, the highest activity of the CK after 24 h rest was observed. Between the -glucuronidase and creatine activities a positive correlation was recognised: control group r=0.477 (p<0.001), supplemented group r=0.671 (p<0.001). However, between the carbonyl groups and the TBARS concentrations and the activity of tested enzymes no relationship was recognized. The obtained results allow to conclude that protein and lipid oxidative damage facilitate the release of cellular enzymes from muscles and supplementation of a single dose of vitamin E does not prevent the process.
