110米高栏是高难度的技术项目,从少年——青年——成年跨栏技术的衔接及训练的连续性,均有很高的要求。要培养合格的高栏后备人才,首先要重视少年时期的选材和训练。一、110米栏的选材 (一)选材年龄:12～13岁,身高1.60～1.65米(未显第二性征)。 (二)预测身高:1.88米(±0.02)。 (三)肌肉形态:脂肪少,有爆发力,肌肉收缩速度快。 (四)关节要求:髓关节柔韧性好,活动幅度大,特别是外展的幅度大。 (五)其他:腰短,向前的韧性极佳,并腿坐时,胸部能碰及大腿。膝关节折叠度佳,直线性好,小腿明显长。踝关节在冲击性条件下的支撑和发力强,蹬离速度快。
The 110-meter-high column is a highly technical project that has high requirements from the convergence of young-young-adult hurdle technology and the continuity of training. To train qualified high column reserve personnel, we must first attach importance to the selection and training of the juvenile period. First, the selection of 110-meter bar (a) selection age: 12 to 13 years old, 1.60 to 1.65 meters tall (no significant secondary sexual characteristics). (B) forecast height: 1.88 meters (± 0.02). (C) muscle morphology: less fat, explosive, muscle contraction faster. (D) joint requirements: flexibility of the medullary joints, activity range, especially the large extent of outreach. (E) Other: short waist, forward toughness excellent, and legged, the chest can touch the thigh. Folding knee good, good linearity, leg was significantly longer. Ankle support in the impact of conditions and hair strength, pedaling speed.
