The purpose of this study was to quantify the kinetics per leg during the one- and two-leg hang power clean using various loads. Nine male track and field athletes performed the one- and two-leg hang power clean on a force platform. The estimated one-repetition maximum was used for the one-leg hang power clean (OHPC), and the one-repetition maximum was used for the two-leg hang power clean (THPC). The loads used were 30%, 60%, and 90% during both trials. We calculated peak power, peak force, and peak rate of force development during the pull phase from the force-time data. The peak power and the peak force for all loads during the OHPC were statistically greater than during the THPC. The peak rates of force development at 60% and 90% during the OHPC were statistically greater than during the THPC. Additionally, the peak power at 90% was significantly less than at 60% during the THPC. These findings suggest that the OHPC at loads of 60% and 90% is a weightlifting exercise that exhibits greater explosive force and power development characteristics than the THPC.
本研究的目的是使用各种负荷来量化单腿和双腿悬垂式高翻过程中每条腿的动力学。九名男性田径运动员在测力平台上进行了单腿和双腿悬垂式高翻。单腿悬垂式高翻(OHPC)使用估计的一次重复最大值,双腿悬垂式高翻(THPC)使用一次重复最大值。两次试验中使用的负荷均为30%、60%和90%。我们根据力-时间数据计算了提拉阶段的峰值功率、峰值力和力发展的峰值速率。OHPC期间所有负荷的峰值功率和峰值力在统计学上均高于THPC期间。OHPC期间60%和90%负荷下的力发展峰值速率在统计学上高于THPC期间。此外,THPC期间90%负荷下的峰值功率显著低于60%负荷下的峰值功率。这些发现表明,60%和90%负荷下的OHPC是一种举重练习,与THPC相比,具有更大的爆发力和力量发展特征。
