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 characteristics of the development of modern science and technology include two aspects, one is a high degree of integration, the other is a high degree of differentiation. Based on the successful practice of guiding high-level high-jump athletes for many years, this article makes a distinction between long-jump projects and puts forward new technical terms for taking-off in back-type high jump. Is a further understanding of the characteristics of high jump. It is also a supplement to the take-off and landing mentioned in the current track and field textbook. The article analyzes the difference between “grab ” and “grub ”. The reasons why some elite high jumpers are obstructed in their performance are related to the failure to complete the take-off. “Catch ” literally means force from the center of extroversion, since it adds and emphasizes the force direction and horizontal cushioning process relative to the take-off point Take good advantage of the speed to increase the take-off effect, to avoid as a result of the wrong take-off direction and hard action caused by injury, which can better play the advantage of back-style jump.
