Professionals involved in training programs for judokas should have access to evidence-based data on various characteristics of these athletes. In the current study, anthropometric (e.g., body height, body mass), physiological (e.g., power based on vertical jump height, maximal handgrip strength), and psychological (e.g., athletic coping skills) characteristics of judokas were examined. The judokas, aged 16-21, were classified into two groups: 30 light weight (males = 19, females = 11) and 27 heavy weight (males = 13, females = 14). Four MANCOVAs separated by sex were performed on the anthropometric, physiological, and psychological data. A discriminant analysis was also carried out. Results showed that heavy-weight males outscored their lighter peers on body height (d = 1.88), arm span (d = 1.88), and maximal handgrip strength. In the females, light-weight judokas outscored their heavier peers on jumping ability (d = 1.02) and peak power bench press (d = 1.20). Female heavy-weight judokas had greater body height (d = 1.46), a longer arm span (d = 1.35), and higher scores on maximal handgrip strength than light-weight judokas. The discriminant analysis revealed that 87.5% and 84.0% of the original grouped male and female judokas, respectively, were correctly classified. No differences in coping skills or self-regulation of learning between categories were observed. It is recommended that professionals involved in training programs may consider these differences in data when developing training programs for young judokas.

轻、重量级青年柔道顶级水平的表现特征

参与柔道训练计划的专业人员应该能够获得关于这些运动员的各种特征的循证数据。在当前的研究中,对柔道运动员的人体测量(例如,身高、体重)、生理(例如,基于垂直跳跃高度的力量、最大握力)和心理(例如,运动应对技巧)特征进行了检查。柔道选手年龄在 16-21 岁之间,分为两组:轻量级 30 名(男性 = 19,女性 = 11)和重量级 27 名(男性 = 13,女性 = 14)。对人体测量学、生理学和心理数据进行了四个按性别分隔的 MANCOVA。还进行了判别分析。结果表明,体重较轻的男性在身高 (d = 1.88)、臂展 (d = 1.88) 和最大握力方面的得分超过了较轻的同龄人。在女性中,轻量级柔道运动员在弹跳能力 (d = 1.02) 和峰值力量卧推 (d = 1.20) 方面的得分超过了较重的同龄人。与轻量级柔道运动员相比,女性重量级柔道运动员的身高 (d = 1.46)、臂展更长 (d = 1.35) 和最大握力得分更高。判别分析显示,原始分组的男性和女性柔道分别有 87.5% 和 84.0% 被正确分类。没有观察到不同类别之间在应对技巧或学习自我调节方面存在差异。建议参与培训项目的专业人士在为年轻柔道运动员制定培训项目时可以考虑这些数据差异。与轻量级柔道运动员相比,女性重量级柔道运动员的身高 (d = 1.46)、臂展更长 (d = 1.35) 和最大握力得分更高。判别分析显示,原始分组的男性和女性柔道分别有 87.5% 和 84.0% 被正确分类。没有观察到不同类别之间在应对技巧或学习自我调节方面存在差异。建议参与培训项目的专业人士在为年轻柔道运动员制定培训项目时可以考虑这些数据差异。与轻量级柔道运动员相比,女性重量级柔道运动员的身高 (d = 1.46)、臂展更长 (d = 1.35) 和最大握力得分更高。判别分析显示,原始分组的男性和女性柔道分别有 87.5% 和 84.0% 被正确分类。没有观察到不同类别之间在应对技巧或学习自我调节方面存在差异。建议参与培训项目的专业人士在为年轻柔道运动员制定培训项目时可以考虑这些数据差异。没有观察到不同类别之间在应对技巧或学习自我调节方面存在差异。建议参与培训项目的专业人士在为年轻柔道运动员制定培训项目时可以考虑这些数据差异。没有观察到不同类别之间在应对技巧或学习自我调节方面存在差异。建议参与培训项目的专业人士在为年轻柔道运动员制定培训项目时可以考虑这些数据差异。
