Аннотация: Studying the issues of metabolic monitoring of the body's reactivity to a standard physical load seems to be an urgent task. Early detection of changes in metabolic parameters in the body of students under the influence of dosed physical activity allows to increase the efficiency of the process of physical education. Research aim. Показать полностьюFor the individualization of physical education of students, to assess the intensity of free-radical oxidation and the activity of the antioxidant system as markers of the body's reactivity to the impact of standard physical activity. Materials and methods. The study involved 75 male students (in 18-21-years-old). As a load test, we used running 100 meters at maximum speed and pulling up from the hang on the bar until the maximum possible number of repetitions was reached. The parameters of oxidative metabolism (intensity of free radical oxidation, total antioxidant activity of blood plasma, concentration of malondialdehyde in blood plasma and erythrocytes) were studied at rest and after each of these physical exercises. Resalts. It has been established that the standard load used contributes to an increase in the intensity of free radical oxidation and a moderate inhibition of the activity of the antioxidant system. In addition, there is an increase in the concentration of malondialdehyde in plasma and erythrocytes after exposure to stress testing. At the same time, the depth of metabolic shifts is of an individual nature, reflecting the current level of adaptive potential. Conclusions. Running 100 meters at maximum speed and pulling up from the hang on the bar can act as a stress factor for testing not only the functional state of the body, but also in monitoring the oxidative metabolism of the body of people performing physical activity, which allows you to individualize the educational process of physical education.
