DYNAMICS OF PSYCHOPHYSIOLOGICAL PARAMETERS OF ATHLETES AND SKIERS DURING THE YEAR SEASONS IN THE EUROPEAN NORTH OF RUSSIA
This work presents the results of a multiply structural and dynamic investigation of seasonal changes in psychophysiological indices of the athletes and skiers in the European North of Russia. The study of the central nervous system functional status and regulation of the autonomic nervous system during the annual training cycle was made to reveal psychophysiological characteristics of young athletes. On the basis of obtained data, the influence on the level of activation of the nervous system characteristic features of activity in which the athlete was engaged in was stated. Special aspects of seasonal dynamics indicators of the operator's working capacity in the studied groups were defined. On the basis of data analysis of variation cardiointervalography relationship of an organism regulatory systems tension with peculiarities of athletic training was defined. As a result, it was found that the skier's organism undergoing aerobic activities during training was less affected by negative environmental factors, compared to the athlete's organism, performing a physical activity with a predominance of anaerobic activity that requires total efficiency of the organism and greater involvement of regulatory systems. So, the athletes are more exposed to risk of exhaustion of physiological reserves, and use of psychophysiological testing for them can serve as means of preventive control of overpressure and overtraining syndrome.
