Influence of psycho-physiological indicators on the result of running on 200 m for high-qualified sprinters with visual impairment on the example of elite sportswoman.

The purpose of the work is to identify the influence of psychophysiological factors on individual performance in athletics sprint in high-qualified athletes with visual impairment on the example of an elite athlete.

 Material and methods. Participants. The study involved a high-qualified athlete, specializing in short-distance running and long jump among athletes with visual impairments (category T12). The course of the study. Individual characteristics of the psychophysiological state and results in running for 200 m for five months were analyzed.

 Results. The models of multiple linear regression between results in 200m run for an elite sportswoman with visual impairment and psychophysiological indices are compiled. High importance of psychophysiological indices in individual performance in running on 100 m is shown. A theoretical concept of the regulation of the running speed of the nervous system in athletes with visual impairment is developed. Conclusions. Compensatory mechanisms of visual function deficiency were established to maintain high speed in the 200 m run as psychophysiological functions: indicators characteristic of sprinters (speed of simple reaction and motility of the nervous system) and specific indicators (efficiency, strength of the nervous system).
