Abstract

The aim of this work is to analyze the amplitude-spectralindices of electromyograms and their correlations with the performanceof subjects during sensorimotor training in different social conditions ofactivity in dyads. The study was carried out on 256 subjects. Asa model of activity, the sensorimotor training “Columns” of thesoftware and hardware complex “BOS-Kinesis” (LTD “Neurotech”, Taganrog)was used with biological feedback from electromyographic signalsfrom the radial flexor of the wrist (flexorcarpi radialis) of the leading hand of the subjects performingthe task in 3 social contexts: individual, competitive and cooperative.As a result of the study of EMG characteristics of the sensorimotoractivity of subjects in different social conditions, the followinggender differences were revealed: at the individual stage, womenhave higher frequency characteristics of EMG, and men have higheramplitude and power of the EMG spectrum at the stages of competitionand cooperation. The dynamics of EMG characteristics in women, unlikemen, is associated with changes in social activity conditions. Thevariability of the frequency characteristics of the EMG spectrumincreased in both men and women under joint activity conditions.Opposite directions of changes in the variability of the integralamplitude and total power of the EMG spectrum in joint activitycontexts compared to individual ones were found: an increase inthese indicators in men, but a decrease in women. In the woman sample,the training performance correlated positively with the averageEMG frequency values in all activity contexts, and negatively withthe amplitude and power of the EMG spectrum during cooperation.The performance of men and women in all sensorimotor activity conditionscorrelated negatively with the variability of EMG characteristics.The results of the study contribute to the understanding of thefeatures of the implementation of voluntary human movements whenperforming sensorimotor tasks in various conditions of social interactions.The obtained data can form the basis for identifying prognosticcriteria for the effectiveness of joint sensorimotor activity tocreate methods for selecting successful teams and optimizing productionprocesses.
