With regard to judo players, like all sport activities, strength training can be divided into general and specific strength training. The specific exercises must correspond with the competitive movement. In addition, in terms of structure, they must correspond with regard to the strength time sequence, and they may be executed with overload. With respect to these important elements, we have envisaged the use of a judo-specific machine. The purpose of this study was to validate this judo-specific machine with regard to the strength training of judokas. To that end, we have measured the maximal pulling forces applied at each hand of judokas (n = 18), playing with the judo-specific machine and with a real partner. A significant difference was found between the maximal pulling forces (F collar and F sleeve) obtained utilizing the judo-specific machine (from 4.9 +/- 0.4 N.kg(-1) to 6.4 +/- 0.3 N.kg(-1) for F collar; from 4.8 +/- 0.2 N.kg(-1) to 6.3 +/- 0.3 N.kg(-1) for F sleeve) and performing with a partner (2.7 +/- 0.2 N.kg(-1) for F collar; 2.5 +/- 0.3 N.kg(-1) for F sleeve). This can be explained by the fact that the partner opposes a low resistance during the judo-throwing technique in comparison with the judo-specific machine. These results show that the judo-specific machine might be used by the judokas to execute specific exercises with overload.
对于柔道运动员来说，与所有体育活动一样，力量训练可分为一般力量训练和专项力量训练。专项训练必须与竞技动作相匹配。此外，在结构方面，它们必须在力量时间序列上相匹配，并且可以进行超负荷训练。考虑到这些重要因素，我们设想使用一种柔道专项器械。本研究的目的是验证这种柔道专项器械在柔道运动员力量训练方面的效果。为此，我们测量了18名柔道运动员在使用该柔道专项器械和与真实对手对抗时，每只手施加的最大拉力。结果发现，使用柔道专项器械时获得的最大拉力（F领和F袖）（F领从4.9±0.4N·kg⁻¹到6.4±0.3N·kg⁻¹；F袖从4.8±0.2N·kg⁻¹到6.3±0.3N·kg⁻¹）与和对手对抗时（F领为2.7±0.2N·kg⁻¹；F袖为2.5±0.3N·kg⁻¹）存在显著差异。这可以解释为，与柔道专项器械相比，对手在柔道投技过程中提供的阻力较小。这些结果表明，柔道运动员可以使用这种柔道专项器械进行超负荷的专项训练。
