Abstract(in English) In this research, we analyzed Mechanomyogram (MMG) and Electoromyogram (EMG) during isometric voluntary contraction by using Matching Pursuit (MP) method which is a time - frequency analysis. The target muscle was biceps brachii muscle. We measured MMG and EMG while subject's isometric force is gradually increased up to 90% of maximal voluntary contraction (MVC) for 12 seconds. As a result on applying MP method to MMG, the frequency domain components under 30%MVC had a peak around 20Hz. However, the peak changed to 40Hz over 30%MVC. The peak is decreased again to 20Hz during 60%-70%MVC. And the peak showed a tendency to increase a during more than 70%MVC. The fast twitch fibers were activated over 30%MVC. From our results, it was indicated that fast twitch fibers were activated after activation of slow twitch fibers as muscle force is increased.
