本文作者通过多年的实践经验，提出了具体提高青少年跳高的起跳腾起高度的具体措施。田径跳跃运动最明显的特征是利用助跑所获得的动能，通过起跳最大限度地改变人体身体重心的运动方向与运动速度。跳高技术的核心是围绕如何利用助跑速度，创造尽可能大的腾起初速度和合理的腾起角。 Through years of practical experience, the author of the paper puts forward concrete measures to raise the level of take-off and landing of youngsters. The most obvious feature of track and field jump exercise is the use of the kinetic energy obtained by the run-up to maximize the change of the body’s center of gravity through the take-off direction and speed of movement. The core of high jump technique is how to make use of the running speed and create the initial speed and reasonable rising angle as much as possible.
