ABSTRACT

This study aimed to analyze whether judo experience, somatic maturation, growth, and physical capacities discriminate young judo athletes from different competitive levels (state and national). Sixty-six young male judo athletes (36 from state and 30 from national level) participated in this study, divided from the annual competitive season. The assessments were performed in two stages separated by 48 hours: anthropometric measurements and physical tests (standing long jump – SLJ, medicine ball throw test-MBT, handgrip strength test – HGS, Special Judo Fitness Test – SJFT and Judogi Grip Isometric Strength Test–JGST). Judo athletes were asked for their date of birth and judo experience. T-test and discriminant analysis were used to compare and discriminate the variables between young judo athletes from state and national groups with the level of significance set at 5%. The main results showed that stature, judo experience, JGST, and SLJ performance were higher in the national group (p < 0.05) and could adequately discriminate competitive levels (structural coefficient >30, p < 0.001). It was concluded that young male judo athletes who compete at the national level are taller, more experienced, and present superior physical performance in tests related to strength and power than athletes from the state group of the same age.

摘要

本研究旨在分析柔道经验、身体成熟度、成长和身体能力是否会区分来自不同竞技水平（州和国家）的年轻柔道运动员。66 名年轻男性柔道运动员（36 名来自州和 30 名来自国家级）参加了这项研究，从每年的竞技赛季开始。评估分两个阶段进行，相隔 48 小时：人体测量和体能测试（立定跳远 - SLJ、药球投掷测试 - MBT、握力测试 - HGS、特殊柔道体能测试 - SJFT 和柔道握力等距力量测试 - JGST）。柔道运动员被要求提供他们的出生日期和柔道经验。T检验和判别分析用于比较和区分来自州和国家组的年轻柔道运动员之间的变量，显着性水平设置为5％。主要结果表明，国家组的身高、柔道经验、JGST和SLJ表现较高（p < 0.05），并且可以充分区分竞争水平（结构系数> 30，p < 0.001）。得出的结论是，参加国家级比赛的年轻男性柔道运动员比同龄国家组的运动员更高，更有经验，并且在与力量和力量相关的测试中表现出更高的身体表现。05）并且可以充分区分竞争水平（结构系数> 30，p <0.001）。得出的结论是，参加国家级比赛的年轻男性柔道运动员比同龄国家组的运动员更高，更有经验，并且在与力量和力量相关的测试中表现出更高的身体表现。05）并且可以充分区分竞争水平（结构系数> 30，p <0.001）。得出的结论是，参加国家级比赛的年轻男性柔道运动员比同龄国家组的运动员更高，更有经验，并且在与力量和力量相关的测试中表现出更高的身体表现。
