Abstract
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.

The peak force of the one-leg hang power clean (OHPC) was significantly greater than two-leg hang power clean (THPC) at 30%
Our results suggest that peak power, peak force, and peak rate of force development (RFD) during the OHPC

Several studies indicate that peak power occurs at a load of 65–80% one-repetition maximum (1RM) during the HPC [1,4,6] Many sports movements, such as running, kicking, changing running direction, and jumping, involve phases of receiving a load on one leg [8].
