【摘要】：以12名专业男子举重运动员为受试者,全面分析了不同相对重量抓举练习的功率输出特点,以期为爆发力训练中抓举练习的重量选择提供科学的依据。方法:受试者在运动捕捉系统下站在测力台上以随机的顺序进行30%~90%1RM重量的抓举练习。然后,计算出人与杠铃所构成整体以及杠铃自身在各个相对重量上的功率、力等指标,再利用重复测量方差分析进行数据统计。结果:整体与杠铃的最大功率分别出现在70%1RM和90%1RM;整体与杠铃的最大速度分别出现40%1RM与30%1RM;两者的最大力值均出现在90%1RM;相对重量对整体力的生成速率无显著影响;杠铃力的生成速率的最大值出现在90%1RM。结论:相对重量对抓举时整体与杠铃的功率变化具有不同的影响。训练实践中应根据运动项目的特征来选择适宜的负重。注重对外界做功的运动员在爆发力训练中其抓举的适宜重量应为≥80%1RM。而注重对自身做功的运动员在爆发力训练中其抓举的适宜重量约为70%1RM,但从力的角度来考虑,其训练中还应包含更大负重的抓举练习。
[Abstract]:Taking 12 professional male weightlifters as subjects, the characteristics of power output of different relative weight snatch exercises are analyzed in order to provide a scientific basis for the weight selection of snatch exercises in explosive force training.Methods: 30%~90%1RM grabbing exercises were carried out in random order by standing on the force table under the motion capture system.Then, the power and force of the barbell and the whole body of the barbell are calculated, and the data are analyzed by the repeated measurement variance analysis.Results: the maximum power of whole and barbell appeared in 70%1RM and 901RM, the maximal velocity of whole and barbell appeared 40%1RM and 301RMrespectively, the most significant value of both appeared in 901RM.The maximum growth rate of barbell force appears at 901RM.Conclusion: relative weight has different influence on the power change of the whole and barbell during snatch.According to the characteristics of sports, the appropriate load should be chosen in training practice.The proper weight of snatch for athletes who pay attention to external work in explosive force training should be 鈮，
