ABSTRACT. A high level of physical activity causes an intensification of energy and plastic processes, which leads to an increase in the need for both physiological oxidation substrates and micronutrients: vitamins and bioelements.

The purpose of this work was to study the content in the hair of young athletes and students of the Khanty-Mansiysk Autonomous Okrug (KhMAO) of Se, Zn and Cu: trace elements that are part of the body's antioxidant defense enzymes and the concentration of antioxidant vitamins A, E, C in blood serum 92 young men were examined: 50 athletes of cyclic sports (biathlon, cross-country skiing) and 42 medical students, average age 19,4±0,48 years.

Results. In hair, the content of trace elements was studied using AES-ICP and MS-ICP methods, in blood serum, the concentration of vitamin C was determined by high-performance liquid chromatography, and vitamins A and E, by fluorimetric method. The average values of Se, Zn and Cu and vitamins A, E, C corresponded to the reference values, but were closer to the minimum limit. The worst provision of athletes with micronutrients-antioxidants was revealed – 1.2-1.1 times lower than the corresponding indicators in students, a significantly lower content of Se (p=0.013) in the hair and vitamin E (p=0.003) in the blood serum in the group of athletes.

Conclusion. A widespread insufficiency of bioelements with an antioxidant spectrum of action and vitamins-antioxidants has been established in young men of the North, who are distinguished by a high level of physical activity compared to students whose physical activity can be assessed as low.
