Abstract

Background. The muscular response of athletes in a judo contest is one of the most important aspect to measure with precision. Objective. Our purpose was to obtain and analyse the variability of strength associated to muscular performance parameters during a judo contest. Methods. Thirty-five men performed five 5-minute bouts with 15 minutes of passive rest. Immediately after each bout, muscular performance parameters were tested: countermovement jump (CMJ), maximal dynamic strength capacities (mean power velocity (MPV), mean strength (MS), maximum strength (MXS), mean power (MP) and maximum power (MXP)) in upper body, dominant (DHS) and non-dominant handgrip isometric strength (NDHS). ANOVA to compare baseline test data and successive bouts was used. Results. ANOVA revealed significant differences in NDHS (p<0.001), DHS (p<0.001), CMJ (p<0.001), MPV (p<0.001), MXS (p<0.001), MP (p<0.001) and MXP (p<0.001). No significant differences in MS (p = 0.008) were found. Some significant correlations between NDHS and ΔPMX (r=0.368, p=0.050), MPV and ΔMXS (r=0.528, p=0.001) and ΔMXP (r=0.683, p<0.001), MPX and ΔMXS (r=0.528, p=0.001) and ΔMP (r=0.877, p<0.001) were found. Conclusion. Due to judo contest can be considered a high intensity exercise, it produces an amount of muscular fatigue and therefore significant loss strength that it cannot be recovery during rest-times between successive bouts. For this reason, it was a high variability in strength production capacities, which are modified during a judo contest.

柔道比赛中力量生产能力的变化

背景。柔道比赛中运动员的肌肉反应是需要精确测量的重要方面之一。目标。我们的目的是获取和分析柔道比赛中与肌肉表现参数相关的力量变异性。方法。35名男性进行了5次5分钟的比赛，并进行了15分钟的被动休息。每回合后立即测试肌肉性能参数:反身跳(CMJ)、最大动态力量能力(平均力量速度(MPV)、平均力量(MS)、最大力量(MXS)、平均力量(MP)和最大功率(MXP)、优势握力(DHS)和非优势握力(NDHS)。采用方差分析比较基线试验数据和连续试验数据。结果。方差分析显示NDHS (p<0.001)、DHS (p<0.001)、CMJ (p<0.001)、MPV (p<0.001)、MXS (p<0.001)、MP (p<0.001)和MXP (p<0.001)存在显著差异。MS无显著性差异(p = 0.008)。NDHS与ΔPMX (r=0.368, p=0.050)、MPV与ΔMXS (r=0.528, p=0.001)、ΔMXP (r=0.683, p<0.001)、MPX与ΔMXS (r=0.528, p=0.001)、ΔMP (r=0.877, p<0.001)存在显著相关。结论。由于柔道比赛可以被认为是一种高强度的运动，它会产生一定程度的肌肉疲劳，因此在连续几场比赛之间的休息时间无法恢复力量。出于这个原因，它是一个高度可变性的力量生产能力，这是修改在柔道比赛。
