Maximum isometric handgrip strength (MIHS) is a relevant parameter for judo performance and is related to health. Understanding the association between MIHS and MIHS relative (MIHSrel) and the absolute lean mass of the arm (LMarm) and the percentage of body fat (%BF) can provide important information for performance and health. The study aimed to investigate the correlation between MIHS and MIHSrel with the LMarm and the %BF of young judokas (sub-19, 15 males and 14 females). MIHS was measured using a multipurpose digital dynamometer with a load cell for computer. Body composition was measured by dual-energy X-ray absorptiometry (DXA). The correlation between MIHS, MIHSrel with LMarm and %BF was verified through Pearson's correlation, with a significance level of < 0.05. Correlation between MIHSrel and %BF was very high only in female judokas for both arms (right, r = -0.76; left, r = -0.75). Correlations between LMarm and MIHS of the right and left arms ranged from very high to almost perfect for both sexes (r = 0.74 to 0.94). These results highlight the importance of strengthening the arms in young judokas, and controlling body fat for performance and health, especially in female judokas.
最大等长握力（MIHS）是柔道表现的一个相关参数，与健康有关。了解 MIHS 与 MIHS 相对值（MIHSrel）以及手臂绝对瘦体重（LMarm）和体脂百分比（%BF）之间的关联，可以为表现和健康提供重要信息。本研究旨在调查年轻柔道运动员（19 岁以下，男性 15 名，女性 14 名）的 MIHS 和 MIHSrel 与 LMarm 和 %BF 之间的相关性。MIHS 使用带有计算机的多用途数字测力计和称重传感器进行测量。身体成分通过双能 X 射线吸收法（DXA）进行测量。通过 Pearson 相关性验证了 MIHS、MIHSrel 与 LMarm 和 %BF 之间的相关性，显著性水平为 < 0.05。仅在女性柔道运动员的双臂（右臂，r = -0.76；左臂，r = -0.75）中，MIHSrel 与 %BF 之间的相关性非常高。男女两性右臂和左臂的 LMarm 和 MIHS 之间的相关性从非常高到几乎完美（r = 0.74 至 0.94）。这些结果强调了在年轻柔道运动员中加强手臂力量以及控制体脂以提高表现和健康的重要性，尤其是对女性柔道运动员而言。
