This study investigates bilateral performance with the Special Judo Fitness Test (SJFT) and its associations with competition performance (CP) and competition volume (CV) in judo.
The SJFT compared movement patterns of the dominant (D) and nondominant (ND) sides on a sample of 27 youth judoka. Repeated-measures analysis of variance was used to determine differences in SJFT execution to the D and ND side, and for associations, the Pearson correlation was used (P < .05).
The total number of throws is significantly higher on the D side, with better performance in the final SJFT index. The CP showed positive correlations with the D side of SJFT executions in the second part of SJFT (P = .042) and the total number of throws (P = .036). On the ND side, the CP showed a positive correlation with the second part of the SJFT (P = .014), a negative correlation with the third part of the SJFT (P = .035), and a positive correlation in the total number of throws (P = .027). CV shows significant correlations with all parameters of the SJFT in the D and ND sides, with stronger correlations on the ND side.
The study presents significantly better performance in judokas' D side in SJFT. Associations between CP and CV with the SJFT were significant in connection to both body sides. It highlights the importance of bilateral movement development and good execution of the throwing techniques for the D and ND body sides of youth judoka to achieve greater CP all year round.
本研究调查了双侧在特殊柔道健身测试（SJFT）中的表现及其与柔道比赛表现（CP）和比赛量（CV）的关系。
SJFT 比较了 27 名青年柔道运动员在优势（D）和非优势（ND）侧的运动模式。使用重复测量方差分析来确定 SJFT 执行到 D 和 ND 侧的差异，对于关联，使用皮尔逊相关系数（P <.05）。
D 侧的投掷总数明显更高，最终 SJFT 指数的表现更好。CP 与 SJFT 执行的 D 侧第二部分呈正相关（P =.042）和总投掷次数（P =.036）。在 ND 侧，CP 与 SJFT 的第二部分呈正相关（P =.014），与 SJFT 的第三部分呈负相关（P =.035），与总投掷次数呈正相关（P =.027）。CV 与 SJFT 的 D 和 ND 侧的所有参数均呈显著相关，ND 侧的相关性更强。
本研究表明，柔道运动员在 SJFT 中 D 侧的表现明显更好。CP 和 CV 与 SJFT 之间的关联与身体两侧均有关。它强调了发展双侧运动和良好执行 D 和 ND 体侧投掷技术的重要性，以实现全年更高的 CP。
