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.

一腿和两腿悬挂式强力清洁过程中的动力学差异

这项研究的目的是量化在使用不同负载的单腿和双腿吊功率清洁过程中每条腿的动力学。九名田径男运动员在受力平台上进行了单腿和双腿悬挂力量的清洁。估计的一重复最大值用于单腿悬挂式强力清洁（OHPC），而一重复最大值用于两腿悬挂式强力清洁（THPC）。在两个试验中，使用的负载分别为30％，60％和90％。我们根据力时数据计算了拉力阶段的峰值功率，峰值力和峰值力发展速度。统计上，OHPC期间所有负载的峰值功率和峰值力均大于THPC期间。在OHPC期间，力发展的峰值速率分别为60％和90％，在统计学上大于THPC。此外，在THPC期间，90％的峰值功率显着小于60％的峰值功率。这些发现表明，在60％和90％的负荷下，OHPC是一项举重运动，与THPC相比，它具有更大的爆炸力和动力发展特性。
