The aims of this study were to compare the maximal isometric handgrip strength of judo athletes from different weight categories and to create a classificatory table for this test. A total of 406 athletes had their maximal isometric handgrip strength measured, following standardized recommendations. Absolute and relative values were calculated for each hand and for the sum of both hands. Weight categories were compared through a one-way analysis of variance, followed by Tukey test. The effect size was determined by partial eta squared, and the relationship between variables was determined using Pearson correlation coefficient. There was a large effect of weight category in absolute handgrip strength for each hand and for the sum of both hands, with lower values for the lighter categories. Conversely, when the relative strength was considered higher values were found for the lighter categories (<0.001). Very large and significant positive correlations (<0.001) were found between right and left for absolute (=0.886) and relative (=0.883) handgrip values. Overall, there was an increase in absolute and a decrease in relative handgrip strength across weight categories. These differences found in grip strength in weight categories are probably linked to differences in muscle mass between them. There was a high correlation between each hand for absolute and relative values, which suggests that assessing only one hand may be enough, and therefore a faster way of evaluation. Finally, the normative classificatory table created may serve as a reference for different purposes.
本研究的目的是比较不同体重级别的柔道运动员的最大等长握力，并为此测试创建一个分类表。按照标准化建议，共对406名运动员的最大等长握力进行了测量。计算了每只手以及双手总和的绝对值和相对值。通过单因素方差分析比较体重级别，随后进行Tukey检验。效应大小由偏 eta 平方确定，变量之间的关系使用Pearson相关系数确定。体重级别对每只手以及双手总和的绝对握力有很大影响，较轻级别的值较低。相反，当考虑相对力量时，较轻级别的值较高（<0.001）。绝对握力值（=0.886）和相对握力值（=0.883）在左右之间发现了非常大且显著的正相关（<0.001）。总体而言，跨体重级别绝对握力增加，相对握力下降。体重级别中握力的这些差异可能与它们之间肌肉质量的差异有关。每只手的绝对和相对值之间存在高度相关性，这表明仅评估一只手可能就足够了，因此是一种更快的评估方法。最后，创建的规范分类表可作为不同目的的参考。
