Electrophysiological neuromuscular systemic characteristics of athletes in power training

Abstract

This study is based on the analysis of electrophysiological characteristics describing the neuromuscular system of athletes during their training sessions, depending on their specialization and level of sport skills. It has been shown that the physiological changes securing the perfection of strength training in weightlifting athletes are mainly concentrated in the peripheral part of their neuromuscular system, namely, at the level of muscles themselves and neuromuscular junctions, and reflected in the electromyogram characteristics as arbitrary movements and M response parameters. At the same time, physiological rearrangements in combat athletes touch the peripheral mechanisms and the central component in the regulation of motor activity and are reflected in the parameters of visual and somatosensory evoked brain potentials. The results disclose an entire set of new important approaches to the functioning of different compartments in the nervous system and the neuromuscular apparatus in athletes of different specializations. They can serve as the basis for the development of practical recommendations on the organization of sports-specialized selection at different stages of athletic perfection, as well as for the physiological support of training process and methods of operating control.
