力量、功率及弹跳速度之间的关系研究——基于对不同负荷的一项 SJ 测试

Objective：To explore the relationship between strength，power and ballistic under different load conditions. Methods：Selected 22 students of physical education as test object，SJ test（Squad Jump Test）was completed by using 3-D force platform（Kistler）under three kinds of load（0%BW，30%BW，60%BW）. Results：The correlation between strength and power under different load conditions is not conclusive，under the condition of 30%BW was the highest and reached a significant leve（lr=0.451，P<0.05），0%BW load conditions is the lowest correlation and not significant（r=0.383，P>0.05）；cor－ relation between the strength and speed of 0%BW and 30%BW loading conditions are relatively low and not significant （r0%BW=0.292；r30%BW=0.350），however，the relationship is relative higher under 60%BW conditions and significantly （r=0.501，P<0.05）；there was a significant correlation between thepower and speed of three load （r0%BW=0.728；r30%bw=0.737；r60%BW=0.633）. Conclusions：Force development simply does not necessarily improve the power and human body movement speed，which is to be influenced by external load；it is to be improved synchronization only in the high load training conditions.
