Takei, S, Hirayama, K, and Okada, J. Comparison of the power output between the hang power clean and hang high pull across a wide range of loads in weightlifters. J Strength Cond Res 35(2S): S84-S88, 2021-The current study compared the peak power output during the hang power clean (HPC) and hang high pull (HHP) across a wide range of external loads in weightlifters. Eight weightlifters completed 1 repetition maximum (1RM) assessment for the HPC (1.59 ± 0.17 kg/body mass) and a power test for the HPC and HHP at relative loads of 40, 60, 70, 80, 90, 95, and 100% 1RM of the HPC. The ground reaction force and 2-dimensional bar position data were recorded to determine the system (barbell + body mass) kinetics and bar height, respectively. System power was calculated as force multiplied by system velocity. The HHP produced significantly greater peak power than the HPC at 40, 60, and 70% 1RM. Conversely, there was no statistical or practical difference in peak power between the exercises at 80, 90, 95, and 100% 1RM. No significant interaction was found in force at peak power, whereas velocity at peak power was significantly greater during the HHP than during the HPC at 40, 60, and 70% 1RM. In addition, significantly greater peak bar height was observed for the HHP than the HPC at 40, 60, and 70% 1RM. From the power output comparisons across loads, the HHP should be used over the HPC at loads of 40-70% 1RM, whereas the HPC and HHP can be interchangeably used at loads of 80-100% 1RM.
武井诚，平山晃，冈田淳。在举重运动员中，广泛的负荷范围内比较高翻和高拉的功率输出。J 力量与调节研究 35（增刊 2）：S84-S88，2021-本研究比较了举重运动员在广泛的外部负荷下进行高翻（HPC）和高拉（HHP）时的峰值功率输出。8 名举重运动员完成了 HPC 的 1 次最大重复评估（1RM；1.59 ± 0.17 kg/体重）和 HPC 和 HHP 的功率测试，相对负荷为 40%、60%、70%、80%、90%、95%和 100%HPC 的 1RM。记录地面反作用力和二维杆位数据，分别确定系统（杠铃+体重）动力学和杆高。系统功率为力乘以系统速度。在 40%、60%和 70%1RM 时，HHP 产生的峰值功率明显大于 HPC。相反，在 80%、90%、95%和 100%1RM 时，两种运动之间的峰值功率没有统计学或实际差异。在峰值功率时，力没有显著的相互作用，而在 40%、60%和 70%1RM 时，峰值功率时的速度在 HHP 中明显大于 HPC。此外，在 40%、60%和 70%1RM 时，HHP 的峰值杆高明显大于 HPC。从跨负荷的功率输出比较来看，在 40-70%1RM 的负荷下，应该使用 HHP 而不是 HPC，而在 80-100%1RM 的负荷下，可以交替使用 HPC 和 HHP。
