摘要

A resistance exercise followed by plyometric exercise is referred to as ”complex training”. This study investigated the effects of the different resistive loads on the subsequent plyometric jumping capacity and its EMG signal for complex training. Twelve college volleyball players performed 5 counter movement jump (CMJ) on a force platform before and after 5 half squat resistive loads of 65% (middle) and 85% (high) of 1 repetition maximum (1-RM) load. The EMG signal was recorded from the rectus femoris, biceps femoris, gastrocenmius, and soleus by the Biovision EMG system. Kinetic parameters were acquired via the Kistler 9287 force platform. The results indicated that the RMS EMG of the rectus femoris was greater during the process of high resistive loads than that of the middle resistive loads (p＜.05), but no significant difference was found in the other muscles (p＞.05). Besides, there were no significant differences for the RMS EMG and kinetic parameters between the 3 bouts CMJ (p＞.05). In conclusion, although subjects who performed high resistive loads exercise recruited more motor units from the primary working muscle than those performing middle resistive loads exercise, the effect of muscle activation might not last to the subsequent plyometric performance. That is to say, acute high resistive loads exercise and middle resistive loads exercise failed to have any acute enhanced or inhibitive effect on the subsequent neuromuscular activation.
