Abstract


The purpose of this study was to examine the effects of ploymetric training on muscle fatigue and maximal rate of force development in volleyball players. Ten college volleyball players volunteered to participate in this study and underwent a 6-week plyometric training. The BTS free EMG and force-plate were used to evaluate the median frequency (MDF) of the rectus femoris (RF), anterior tibialis (AT), lateral gastrocnemius (LG), biceps femoris (BF) and maximum rate of force development (mRFD). The results revealed that the plyometric training significantly improves the MDF of RF and AT and mRFD. This study demonstrated hat by using plyometric training could facilitate the mRFD and postpone muscle fatigue for trained volleyball players.
