ABSTRACT
The study of the neural mechanisms underlying sports performance was aimed at studying the characteristics of the brain electrical activity of athletes-fighters in comparison with non-athletes. Thirty young men of 19.97±0.23 years old (with the height of 179.82±2.15 cm and the body weight of 78.61±1.68 kg) engaged in wrestling (with the qualification "Master of Sports"), and thirty young men of 19.25±0.18 years old (with the height of 178.35±2.25 cm and the body weight of 77.93±1.45 kg), not involved in sports, analyzed the frequency ranges delta, theta, alpha, beta 1 and beta 2 rhythms of electroencephalography (EEG) at rest in three epochs: the first epoch with closed eyes, the second epoch with open eyes, and the third epoch with closed eyes. The results of the study showed that in wrestlers, the neural advantage over non-athletes is expressed only in a decrease in alpha rhythm fluctuations: with closed eyes in the left hemisphere by 17.07% (p<0.05), and in the right hemisphere by 17.35% (p<0.05). With open eyes, the difference was 21.17% (p<0.01) in the left hemisphere and 19.27% (p<0.05) in the right hemisphere, which indicates a lower cortical activity of the brain of athletes. At the same time, the coefficient of reactivity (CR) of the alpha rhythm during the receipt of visual information in athletes in the left hemisphere is 20% higher, and when it is interrupted, it is 18% lower than in non-athletes. In the right hemisphere, CR does not differ. We concluded that wrestlers recruited fewer neural resources without compromising performance, supporting the hypothesis of neuronal flexibility in the brains of athletes compared to non-athletes.
