摘要
现代科技发展的特征包含两个方面,一方面是高度的综合,另一方面是高度的分化。在多年指导高水平跳高运动员成功实践的基础上,区别跳远等项目,提出了背越式跳高起跳时"抓"地起跳的新的技术术语。是对跳高特征的更进一步的认识。也是对现行田径教科书所提到的"扒"地起跳的补充。文章分析了"抓"和"扒"的不同。阐述了一些优秀跳高运动员成绩受阻的原因与没有完成好"抓"地起跳相关。"抓"从字面意思是从外向中心用力,由于它增加了和强调了相对于起跳点的"由后向前"的用力方向和水平缓冲用力过程,从而使得起跳时人体能够更好地利用速度来增加起跳效果,能够最大限度地避免由于起跳时错误的用力方向和用力动作而引起的损伤,从而能更好地发挥出背越式跳高的优势。
The development of modern science and technology exhibits two characteristics: high integration and high specialization.In this thesis,the author distinguishes the sport items like long jump,and proposes the new technical term of 'grip' take-off in Flop high jump on the basis of many years' experiences in coaching high level high-jump athletes.This is a further perception of high-jump features,and also a supplement to the 'cling' take-off technique mentioned in existing track and field teaching materials.The author analyzes the difference between 'grip' and 'cling',and indicates that some excellent high-jump athletes can not achieve good results due to unsuccessful 'grip' take-off.The word 'grip' literally means imposing a force from outside to the center.Since it enhances and emphasizes the 'back to front' moving direction relative to the take-off point and the exertion process of horizontal buffering,it allows human body to improve take-off efficiency by better use of speed,and thus minimizes the injury caused by wrong moving direction or action at the moment of take-off.Therefore,it helps athletes better exert the advantages of Flop high jump.
