Recent studies indicate that the utilization of the hexagonal barbell jump squat (HBJS) compared with the traditional barbell jump squat may offer a superior method of developing peak power. The notion that a single optimal load may be prescribed in training programs aiming to develop peak power is subject to debate. The purpose of this study was to identify the optimal load corresponding with peak power output during the HBJS in professional rugby union players. Seventeen professional rugby union players participated in this study. Participants performed 3 unloaded countermovement jumps on a force plate and 3 HBJS at each of the following randomized loads: 10, 20, 30, and 40% of box squat 1 repetition maximum (1RM). Peak power output was the dependent variable of interest. A one-way repeated measures analysis of variance was conducted to compare peak power output across each load. Peak power output was the dependent variable of interest. A significant main effect for load was observed (Wilk's Lambda = 0.11, F(4,13) = 18.07, p < 0.01, partial η2 = 0.88). Results of the Bonferroni-adjusted pairwise comparisons indicated that peak power output in the HBJS is optimized at a load range between 10 and 20% of box squat 1RM. The results of this study indicate that the use of the HBJS with a training load between 10 and 20% of box squat 1RM optimizes peak power output in professional rugby union players.
近期研究表明，与传统杠铃深蹲跳相比，使用六角杠铃深蹲跳（HBJS）可能是一种更优的发展峰值功率的方法。在旨在发展峰值功率的训练计划中规定单一最佳负荷这一观点存在争议。本研究的目的是确定职业英式橄榄球联盟球员在进行六角杠铃深蹲跳时与峰值功率输出相对应的最佳负荷。17名职业英式橄榄球联盟球员参与了本研究。参与者在测力板上进行3次无负荷的反向移动跳，以及在以下随机负荷下各进行3次六角杠铃深蹲跳：箱式深蹲1次重复最大值（1RM）的10%、20%、30%和40%。峰值功率输出是感兴趣的因变量。进行了单因素重复测量方差分析以比较各负荷下的峰值功率输出。峰值功率输出是感兴趣的因变量。观察到负荷有显著的主效应（威尔克斯Lambda = 0.11，F(4,13) = 18.07，p < 0.01，偏η² = 0.88）。Bonferroni校正的成对比较结果表明，六角杠铃深蹲跳的峰值功率输出在箱式深蹲1RM的10%至20%的负荷范围内达到最佳。本研究结果表明，在职业英式橄榄球联盟球员中，使用箱式深蹲1RM的10%至20%的训练负荷进行六角杠铃深蹲跳可优化峰值功率输出。
