Abstract

This study aimed to describe the bilateral deficit (BLD) during the countermovement jump (CMJ) in judo athletes and determine the relationship between the BLD and judo-specific performance. Fourteen male judo athletes participated. Athletes performed three specific judo tests, Maximal Sprint Speed Judo Test, Maximal Aerobic Speed Judo Test and Special Judo Fitness Test (SJFT), and double- and single-leg CMJ. The following CMJ variables were used: jump height (JH), mean (MPO) and peak (PPO) power output, peak force (PF), peak velocity (PV) and impulse (IMP). The Pearson's or Spearman's test were used (p < 0.05). The results show that the BLD is found in all CMJ parameters (20 to 31%). Negative correlations between first set of SJFT_TT (total throws) and BLD in PF (r = -0.60; p= 0.022) and between the second set of SJFT_TT and BLD in MPO (r= -0.74;p = 0.002), PV (r =-0.59;p = 0.025) and IMP (r =-0.55; p = 0.040) were found. Also, negative correlations between SJFT_TT and the BLD in all CMJ parameters (r= -0.53 to -0.85; p < 0.05) were found. Higher values of BLD are related to poor SJFT_TT performance.

反动作跳跃中的双侧缺陷及其与柔道专项表现的关系。

本研究旨在描述柔道运动员在反动作跳跃(CMJ)时的双侧缺陷(BLD)，并确定BLD与柔道专项成绩之间的关系。14名男子柔道运动员参加了比赛。运动员进行了三种特定的柔道测试，即最大冲刺速度测试、最大有氧速度测试和特殊柔道体能测试(SJFT)，以及双腿和单腿CMJ。使用以下CMJ变量:跳跃高度(JH)、平均(MPO)和峰值(PPO)输出功率、峰值力(PF)、峰值速度(PV)和冲量(IMP)。使用Pearson’s或Spearman’s检验(p TT(总投掷数))和BLD (r = -0.60;第二组SJFTTT与BLD在MPO (r= -0.74;p = 0.002)、PV (r= -0.59;p = 0.025)和IMP (r= -0.55;P = 0.040)。此外，SJFTTT与BLD在所有CMJ参数中呈负相关(r= -0.53 ~ -0.85;p TT性能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
