Abstract

Introduction: To perform a technical action, the elite judo athlete examines the direction of attack relative to the opponent's body position. This study aimed to analyze and compare the most frequent and effective attack directions carried out by male Olympic medalists. Materials and Methods: A sample of 112 male medalists performed 3,664 attacks in four Olympic tournaments (2004–2016). ANOVA (one factor) determined inter and intra-Olympic comparisons, followed by the post hoc Bonferroni test (p< 0.05). Eta squared η2 and Cohen's d calculated the effect size, respectively. Results: Olympic medalists oriented their attacks principally in right forward (30.5±11.3%), left forward (29.9±10.5%), left backward (18.8±8.1%), and right backward (15.8±6.1%). The effectiveness of right forward (25.7±13.1%) and left forward (26.2±12.5%) dominates left backward (20.5±10.1%) and right backward (15.5±9.7%), respectively. In terms of frequencies and effectiveness, the contribution of secondary directions is negligible. Conclusions: Attacking in eight orientations made the defense vulnerable. Beside the uncertainty and unpredictability, they created more points of imbalance to overcome defensive issues.
奥运会男子柔道奖牌获得者的进攻方向及其效果
简介:为了完成一个技术动作,优秀的柔道运动员检查相对于对手身体位置的攻击方向。本研究旨在分析和比较男性奥运奖牌获得者最频繁和最有效的进攻方向。材料与方法:在2004-2016年的四届奥运会中,112名男性奖牌获得者进行了3,664次攻击。单因素方差分析(ANOVA)确定了奥运期间和奥运期间的比较,随后进行了事后Bonferroni检验(p<0.05)。Eta²η2和Cohen’s d分别计算了效应大小。结果:奥运奖牌运动员的进攻方向主要为右前(30.5±11.3%)、左前(29.9±10.5%)、左后(18.8±8.1%)和右后(15.8±6.1%)。右前位(25.7±13.1%)和左前位(26.2±12.5%)分别优于左后位(20.5±10.1%)和右后位(15.5±9.7%)。在频率和有效性方面,二次方向的贡献可以忽略不计。结论:八个方向的进攻使防守变得脆弱。除了不确定性和不可预测性,他们还创造了更多的不平衡点来克服防守问题。
