CHANGE OF THE ANTIOXIDANT STATUS OF BLOOD ATHLETES OF CYCLIC SPORTS DURING IN DIFFERENT PERIODS OF TRAINING PROCESS
A biochemical examination of highly cyclic sports athletes in different periods of the training process: the transition and preparation. The control group comprised subjects who are not involved in sports. Studied indicators activity of antioxidant system. The estimation of these parameters change depending on the intensity of physical activity. It is shown that in the blood of athletes preparation period of training, experiencing maximum volume and intensity of exercise, a statistically significant change indicators activity of antioxidant enzymes. In particular, in blood the athletes preparatory training period decreases the activity of glutathione peroxidase, glutathione reductase and glutathione.
