This research adopted VICON system, force measurement forceplat in addition to BIOPAC system to explore the scenarios for lower limb exercise studies in volley ball blocking as well as dynamics. And it applied ANYBODY software to proceed to muscle simulation for the 42 muscles of the lower limb so as to collect the nine muscles inspection simulations from the surface electromyography (SEMG), which indicated the trend for lower limb muscle activation. The nine muscles from the surface electromyography (SEMG) are used to inspect the muscle characteristics of the objects under simulation. From the signals of surface electromyography (SEMG), it is known that after the Vastus med, Vastus lat and Rectus femoris are activated first, followed by the activations for gastroc-nemius medial head and the gastroc-nemius lateral head. And prior leaving the ground, the muscles to be activated are semitendinosus muscle, Vastus Medialis, Vastus lat and Rectus femoris of the Semimembranosus. And in the process of jumping, they all show common scenarios of contraction. And there are three-phased phenomena observed for tibialis anterior muscle and Vastus lat. And after the strength exertion from the Vastus med, Vastus lat and Rectus femoris, it is followed with gastroc-nemius medial head and gastroc-nemius lateral head. And prior leaving the ground, the muscles to be activated are semitendinosus muscle and Semimembranosus. Therefore after extensive data comparison, it is discovered that those similar are as follow: Rectus femoris, Vastus med, semitendinosus muscle, Vastus Medialis, biceps femoris, gastroc-nemius lateral head and gastroc-nemius medial head. And those not similar are also listed as follow: Semimembranosus and tibialis anterior muscle.
