Abstract

Objective. To investigate the functional state of the neuromuscular system in different gender groups of highly skilled boxers, to identify its possible functional and structural disorders using electromyography (EMG) methods. Methods. Method of H-reflex of the soleus muscle, determination of the nerve conduction velocity of the tibial median and ulnar nerves using the Nicolet Viking Select neurodiagnostic complex, USA-Germany. Results. Deviations of the EMG parameters from the norm, namely the decrease of the H-response amplitudes and decrease in the ratio of the maximum amplitudes of the H- and M-responses of the soleus muscle have been revealed in two of seven men in the group (28%) and in one woman of nine (11%) from different gender groups of highly skilled boxers. In the group of athletes whose EMG values were within normal range, in 85% of men and 33% of women a significant asymmetry of amplitudes of the M-responses of the soleus muscle have been observed, which may be a sign of the locomotorium response to the effect of inadequate loading and increase the risk of disordered functioning of the neuromuscular system. There were no statistically significant gender differences in EMG indices in boxers as compared to biathletes, canoeists and kayakers. This may be due to slight difference in muscle fiber volume between men and women and the reflection of equally directed adaptive changes in the functional status of the neuromuscular system in boxers of different gender groups. Conclusions. Deviation of EMG parameters from the norm and significant asymmetry of amplitudes of M-responses of the soleus muscle, which increase the risk of injury, have been revealed in both gender groups of skilled athletes specialized in boxing. The absence of significant gender differences in EMG parameters in boxers may indicate the similarity of specific adaptation in men and women to training loads in boxing
