(1) Study aim: This is a comparative study for judo and jujutsu practitioners. It has an intrinsic value. The aim of this study was to showcase a comparison of practitioners of judo and a similar martial art jujutsu with regard to manual abilities. The study applied the measurement of simple reaction time in response to a visual stimulus and handgrip measurement. (2) Materials and Methods: The group comprising = 69 black belts from Poland and Germany (including 30 from judo and 39 from jujutsu) applied two trials: "grasping of Ditrich rod" and dynamometric handgrip measurement. The analysis of the results involved the calculations of arithmetic means, standard deviations, and Pearson correlations. Analysis of the differences (Mann-Whitney test) and Student's -test were also applied to establish statistical differences. (3) Results: In the test involving handgrip measurement, the subjects from Poland (both those practicing judo and jujutsu) gained better results compared to their German counterparts. In the test involving grasping of Ditrich rod, a positive correlation was demonstrated in the group of German judokas between the age and reaction time of the subjects (r = 0.66, < 0.05), as well as in the group of jujutsu subjects between body weight and the reaction time (r = 0.49, < 0.05). A significant and strong correlation between handgrip and weight was also established for the group of German judokas (r = 0.75, < 0.05). In Polish competitors, the correlations were only established between the age and handgrip measurements (r = 0.49, < 0.05). (4) Conclusions: Simple reaction times in response to visual stimulation were shorter in the subjects practicing the martial art jujutsu. However, the statement regarding the advantage of the judokas in terms of handgrip force was not confirmed by the results.
(1) 研究目的：这是一项针对柔道和柔术练习者的比较研究。它具有内在价值。本研究的目的是展示柔道练习者与类似武术柔术练习者在手部能力方面的比较。该研究采用了对视觉刺激的简单反应时间测量和握力测量。(2) 材料与方法：该组由来自波兰和德国的69名黑带选手组成（包括30名柔道选手和39名柔术选手），进行了两项测试：“抓取迪特里希杆”和握力测量。结果分析包括算术平均值、标准差和皮尔逊相关性的计算。还应用了差异分析（曼-惠特尼U检验）和学生t检验来确定统计差异。(3) 结果：在握力测量测试中，波兰的受试者（包括柔道和柔术练习者）比德国的受试者取得了更好的成绩。在涉及抓取迪特里希杆的测试中，德国柔道选手中受试者的年龄与反应时间之间存在正相关（r = 0.66，P < 0.05），柔术选手中体重与反应时间之间也存在正相关（r = 0.49，P < 0.05）。德国柔道选手组中握力与体重之间也建立了显著且强烈的相关性（r = 0.75，P < 0.05）。在波兰选手中，仅在年龄与握力测量之间建立了相关性（r = 0.49，P < 0.05）。(4) 结论：练习柔术的受试者对视觉刺激的简单反应时间较短。然而，结果并未证实柔道选手在握力方面具有优势这一说法。
