【摘要】：以12名專業(yè)男子舉重運動員為受試者,全面分析了不同相對重量抓舉練習(xí)的功率輸出特點,以期為爆發(fā)力訓(xùn)練中抓舉練習(xí)的重量選擇提供科學(xué)的依據(jù)。方法:受試者在運動捕捉系統(tǒng)下站在測力臺上以隨機的順序進(jìn)行30%~90%1RM重量的抓舉練習(xí)。然后,計算出人與杠鈴所構(gòu)成整體以及杠鈴自身在各個相對重量上的功率、力等指標(biāo),再利用重復(fù)測量方差分析進(jìn)行數(shù)據(jù)統(tǒng)計。結(jié)果:整體與杠鈴的最大功率分別出現(xiàn)在70%1RM和90%1RM;整體與杠鈴的最大速度分別出現(xiàn)40%1RM與30%1RM;兩者的最大力值均出現(xiàn)在90%1RM;相對重量對整體力的生成速率無顯著影響;杠鈴力的生成速率的最大值出現(xiàn)在90%1RM。結(jié)論:相對重量對抓舉時整體與杠鈴的功率變化具有不同的影響。訓(xùn)練實踐中應(yīng)根據(jù)運動項目的特征來選擇適宜的負(fù)重。注重對外界做功的運動員在爆發(fā)力訓(xùn)練中其抓舉的適宜重量應(yīng)為≥80%1RM。而注重對自身做功的運動員在爆發(fā)力訓(xùn)練中其抓舉的適宜重量約為70%1RM,但從力的角度來考慮,其訓(xùn)練中還應(yīng)包含更大負(fù)重的抓舉練習(xí)。
[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，
