The aim of this study was to describe the variations in power performance of elite Paralympic judo athletes across three consecutive training cycles of preparation for the ParaPan American Games, the World Championship and the Paralympic Games. Eleven Paralympic judokas from the Brazilian National team participated in this study. They were repeatedly assessed using squat and countermovement jumps, mean propulsive power (MPP) in the jump-squat (JS), the bench press and prone bench pull at several moments of the preparation. Training supervision based on the optimum power zone (range of loads where power production is maximized) was provided in the final cycle, prior to the Paralympic Games. Magnitude-based inference was used to compare the repeated measurements of power performance. Lower and upper limb muscle power gradually increased throughout the cycles; however, the best results in all exercises were observed prior to the Paralympic Games, during which the team won four silver medals. As an illustration, prior to participation in the Paralympic Games the MPP in the JS was likely to very likely higher than prior to the World Championship (effect size [ES] = 0.77) and ParaPan American Games (ES = 0.53), and in January and March 2016 (ES = 0.98 and 0.92, respectively; months preceding the Paralympic Games). Power performance assessments can provide information about the evolution of Paralympic judokas, and training at the optimum power zone seems to constitute an effective method to improve lower and upper limb power in these athletes.
本研究的目的是描述精英残奥柔道运动员在为泛美运动会、世界锦标赛和残奥会做准备的连续三个训练周期中的力量表现变化。来自巴西国家队的11名残奥柔道运动员参与了本研究。在准备过程中的几个时刻，对他们进行深蹲和反向移动跳、跳蹲（JS）中的平均推进力（MPP）、卧推和俯卧位引体向上的重复评估。在残奥会前的最后一个周期，提供基于最佳力量区（力量产生最大化的负荷范围）的训练监督。基于量级的推断用于比较力量表现的重复测量结果。上下肢肌肉力量在整个周期中逐渐增加；然而，在所有练习中，最佳成绩是在残奥会之前观察到的，在此期间该团队赢得了四枚银牌。例如，在参加残奥会之前，JS中的MPP很可能高于世界锦标赛之前（效应量[ES]=0.77）和泛美运动会之前（ES=0.53），以及2016年1月和3月（分别为ES=0.98和0.92；残奥会前的月份）。力量表现评估可以提供有关残奥柔道运动员发展情况的信息，在最佳力量区进行训练似乎是提高这些运动员上下肢力量的有效方法。
