运用对比分析法对中外优秀男子跳远运动员起跳有关环节的运动学参数研究发现,我国优秀跳远运动员助跑绝对速度较低;在起跳过程中身体重心水平速度损失较小,从而获得的垂直分速度亦较小,腾起角度相应偏小;踏板缓冲阶段动作消极等因素是我国跳远运动水平落后的症结所在。
Using comparative analysis to study the kinematic parameters of the take-off of the elite male long-jump athletes at home and abroad, it is found that the run-up speed of the elite long-jump athletes is relatively low. The horizontal speed of the body’s center of gravity is smaller during the take-off, Small, rising angle correspondingly small; pedal buffer stage negative action and other factors is the level of backwardness in China is the crux of the problem.
