Abstract. We present here experimental records of surface
electromyogramms (sEMG) and their average power spectra. We demonstrate that the
detailed analysis of all sEMG power spectra reveals significant peaks at the
characteristic position. This position can be associated with the average
repetition rate of a single motor unit action potential. Also, we prove here
the possibility to measure the dependence of the myo-pulse repetition rate on
the muscle mechanical load.
