摘要：
The study addressed the problem of obtaining information on the operation of motor units in the biceps brachii muscle by recording and spectral processing of its mechanomyograms during maintenance of fatiguing isometric tension. The following spectral characteristics of mechanomyograms were determined: total power in the range 1-60 Hz and the percentage of power in the subranges 1-20, 20-40, and 40-60 Hz. Stereotypes in the operation of motor units were not observed in different traces. The possibility of obtaining useful information by analyzing changes in the entire set of parameters of individual traces was evaluated.
