This study aimed to analyze if the ratio standard or the allometry is the best scaling methods of handgrip strength (HGS) for body mass (BM) in judo athletes and nonathletes, and to verify if the HGS mean values are higher in judo athletes than nonathletes when the BM effect is removed. One hundred forty-two individuals, being 88 judo athletes and 54 non-athletes participated in this study. The maximal isometric HGS was measured in judo athletes and nonathletes in the preferred hand. Only the allometry method was able to remove the BM effect of HGS. The al-lometric exponents found for athletes was b=0.68 and b=0.563 for non-athletes. A common allometric exponent was identified as (b=0.64) for comparing judo athletes and nonathletes. However, neither was able to allow for the comparison between groups due to a distortion of (bias; <0.01). Thus, an index (HGS) was proposed to allow within-group (judo athletes and nonathletes) and between-group (judo athletes vs. nonathletes) comparison, removing the effect of BM. In summary, the allometric exponent based on the theory of geometric similarity (b=0.67) was able to remove the BM effect of HGS in judo athletes. An index (HGS) is suggested for classification (or rank) of the judoka in relation to the expected average of HGS.
本研究旨在分析比率标准或异速生长法是否是柔道运动员和非运动员中握力（HGS）相对于体重（BM）的最佳缩放方法，并验证在消除BM影响后，柔道运动员的HGS平均值是否高于非运动员。142名个体参与了本研究，其中88名柔道运动员和54名非运动员。测量了柔道运动员和非运动员优势手的最大等长HGS。只有异速生长法能够消除HGS的BM影响。运动员的异速生长指数为b = 0.68，非运动员为b = 0.563。比较柔道运动员和非运动员时，确定了一个共同的异速生长指数（b = 0.64）。然而，由于偏差（<0.01）导致的失真，两者都无法进行组间比较。因此，提出了一个指数（HGS），以允许在组内（柔道运动员和非运动员）和组间（柔道运动员与非运动员）进行比较，消除BM的影响。总之，基于几何相似性理论的异速生长指数（b = 0.67）能够消除柔道运动员HGS的BM影响。建议使用一个指数（HGS）来对柔道运动员相对于预期HGS平均值进行分类（或排名）。
