Influence of typological features of the nervous system on individual performance in running for short distances in athletes with visual impairment on the example of an elite athlete

Introduction: The purpose of the work is to theoretically and experimentally substantiate the influence of psychophysiological factors on individual performance in athletics sprint in high-qualified athletes on the example of an elite athlete. Material and methods: In this study, participated 1 athlete, 36 years of age, female. Athlete is specializing in short-distance running and long jump, the European Athletics Champion 2010; prize winner of the World Paralympic and Paralympic Games among athletes with visual impairments (T12 category) in 2016. The study was conducted for 5 months. Twice a week, testing was conducted (psychophysiological indicators and running speed); 36 tests of one athlete were conducted. Individual characteristics of the psychophysiological state and results in running for 100 m for five months were analyzed.Results. The models of multiple linear regression between results in 100 m run for an elite athlete with visual impairment and psychophysiological indices are compiled. High importance of psychophysiological indices in individual performance in running on 100 m is shown. Conclusions. Compensatory mechanisms of visual function deficiency were established to maintain high speed in the 100 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).
