The relationship of endogenous intoxication processes, lipid peroxidation and antioxidant protection in the saliva of kickboxing athletes
Abstract
Objective: to study the state of the processes of endogenous intoxication, lipoperoxidation and antioxidant protection in the saliva of athletes during exercise and during the recovery period after it. Materials and methods: the study includes 20 professional athletes and 40 volunteers who do not have regular high physical exertion. Samples of saliva in athletes were taken three times: at rest, 10-15 minutes after training and again at rest; in the control group - once. In the samples, the content of products of lipoperoxidation, endogenous intoxication, activity of antioxidant enzymes was determined. Results: it is shown that the training process is accompanied by an intensification of the processes of lipoperoxidation and endogenous intoxication. In the recovery period, the level of lipid peroxidation products remains elevated, and the content of protein toxins quickly returns to normal. The activity of antioxidant enzymes after exercise is reduced, but increases in the recovery period. This is due to compensatory mechanisms in the antioxidant defense system. Conclusions: it is necessary to monitor the parameters of the subjects for timely correction of the effects of oxidative stress.
