摘要

在过去的十年里,举重衍生品已经成为青少年运动员中越来越受欢迎的一种抗阻训练形式。本研究旨在研究青年运动员在悬空力量清洁时的负荷情况,以确定力量、力量、力量发展速度和杠铃速度的最佳负荷参数。男青年运动员16名(年龄:16.94±0.97岁;高度:180.08±8.14 cm;体重:81.06±15.04 kg;悬挂清洁1RM(70.17±14.41 kg)以10%的间隔进行三次悬挂动力清洁,间隔范围为一次重复最大值(1RM)的30-90%。单向重复测量ANONAs显示,外部负荷对所有变量的峰值和平均值有显著影响(p < 0.05)。最值得注意的是,峰值功率在70% 1RM时达到最大,而60-90% 1RM之间差异不显著。力发展的峰值速率在90%1RM时达到最大,但并不显著大于50% -90%1RM。相反,杠铃速度峰值在30% 1RM时达到最大值,明显大于50-90% 1RM。虽然力量的结果与年龄更大、更强壮的运动员相似,但与更发达的运动员相比,本研究中的年轻人在不同的外部负荷下最大限度地提高了杠铃速度和力量发展速度。这些结果似乎表明,青年运动员需要达到更高水平的力量,才能在保持高杠铃速度的同时进行高相对外部负荷的训练。

An Examination of Loading Profiles for Youth Athletes Performing the Hang Power Clean
Weightlifting derivatives have become an increasingly popular form of resistance training among youth athletes over the past decade. This study aimed to examine the loading profiles of youth athletes during the hang power clean to determine optimal loading parameters for force, power, rate of force development, and barbell velocity. Sixteen male youth athletes (Age: 16.94 ± 0.97 years; Height: 180.08 ± 8.14 cm; Body mass: 81.06 ± 15.04 kg; Hang Clean 1RM 70.17 ± 14.41 kg) performed three repetitions of the hang power clean at 10% intervals ranging from 30-90% of their one-repetition maximum (1RM). One-way repeated measures ANONAs revealed that external load had a significant effect on the peak and average of all variables examined (p < 0.05). Most notably, peak power was maximized at 70% 1RM which was not significantly different 60-90% 1RM. Peak rate of force development was maximized at 90% 1RM, though it was not significantly greater than 50-90%1RM. Conversely peak barbell velocity was maximized at 30% 1RM which was significantly greater than 50-90% 1RM. While the results for power are similar to that of older, stronger athletes, the youth population in this study maximized barbell velocity and rate of force development at different external loads compared to more developed athletes. These results seem to suggest that youth athletes need to achieve a higher level of strength before they are capable of training with high relative external loads while maintaining high barbell velocities.
