Abstract

In judo, the attacking system is grounded on several determinants of the chances to throw. In our study, data regarding four determinants of the attacking system were collected in order to classify the standing scoring actions: the attacking type (direct/counter-attack), the throwing area (forward/backward), the technique's category (based on motor criteria), and the lateral structure of fighting (contenders with a symmetrical/asymmetrical position). To study the usefulness of such an analysis, the standing scoring actions of the 2013 Judo World Championship were analyzed as an example of elite judo's attacking system ( = 775). The Pearson's chi-squared test and Cramér's V were used to analyze the hypothesis of a uniform distribution or the association between variables and the strength of such an association, respectively. The scoring actions ( < 0.001) were mostly direct attacks (82.6%), in the forward throw area (57.5%), and in an asymmetrical position (67.2%). All of the variables were associated ( < 0.05; V = 0.11⁻0.54), with higher proportions of counter-attacks and attacks occurring on the backward thrown area during asymmetrical structures than the expected. Some categories of techniques were observed more than expected, depending on the symmetrical or asymmetrical structure. Our data augment the knowledge of standing judo by showing features of the attacking system, suggesting strategies for optimizing performance.

摘要

在柔道中,进攻体系基于几个决定投摔成功率的因素。在我们的研究中,收集了关于进攻体系四个决定因素的数据,以便对站立得分动作进行分类:进攻类型(直接进攻/反击)、投摔区域(向前/向后)、技术类别(基于动作标准)以及战斗的横向结构(选手处于对称/不对称姿势)。为了研究这种分析的实用性,以2013年柔道世界锦标赛的站立得分动作作为精英柔道进攻体系的一个例子进行分析(=775)。分别使用皮尔逊卡方检验和克莱默V系数来分析均匀分布的假设或变量之间的关联以及这种关联的强度。得分动作(<0.001)大多是直接进攻(82.6%),发生在向前投摔区域(57.5%),且处于不对称姿势(67.2%)。所有变量都有关联(<0.05;V=0.11⁻0.54),在不对称结构中,反击和在向后投摔区域的进攻比例高于预期。根据对称或不对称结构,某些技术类别出现的频率高于预期。我们的数据通过展示进攻体系的特征,增加了对站立式柔道的认识,为优化表现提供了策略。
