Abstract(in English) The purpose of this study is to clarify behaviors of motor unit(MU)s under isovelocity voluntary movements in the elbow joint flexor muscle. In this study, the multi-channel surface electrode was developed for measuring the electromyogram (EMG). The behaviors of MUs during movements could be rccognized by decomposing the surface EMG into each MU active potential(MUAP)s. Surfacc EMGS were recorded from the m, beceps brachii of 3 normal subjects with isovelocity of 1O, 15, 20, 25 deg/sec. As a result, there were 74 MUs identified in three, 48 of them were found to have almost constant firing rates in dynamic contractions. It was recognized that there were 19 MUs to begin firing during movement, 23 MUs to stop doing so. And also we could find 3 suspended MUs.
