摘 要:采用文献资料法、影像解析法和数理统计法,对国内3名优秀男子撑竿跳高运动员腾空阶段的竿上技术进行分析。结果表明:腾空阶段的竿上技术可以分为助力阶段和阻力阶段进行分析;良好的摆体技术可以减少撑竿阻力阶段的速度损失率,我国选手的摆体技术同世界级运动员有明显差别,主要是躯干后仰过大和起跳腿没有较好的保持伸直状态;我国选手的弯竿量小,摆体技术缺陷和BMI指数较低是主要原因,弯竿量同左手离竿时刻的垂直速度呈显著正相关,同竿上的腾空高度成正比;我国运动员重心最高点与横杆高度的差值过大,需要改进过杆技术。This paper adopted the methods of literature review, image analytical method, and mathematic statistics to analyze the flighting technique of Chinese elite male pole vaulters. The result shows that the pole-technique of flighting stage can divide into resistance and assistance. The technique of body-pendu lum can reduce the velocity loss rate. Chinese athletes has obvious difference with world-class athletes in the technique of body-pendulum, the primary cause is larger angle of trunk back-tilt and can't keep straight state of take-off leg. The pole-bend range of Chinese athletes is not large enough; the main reason is BMI index and the defect of the technique of body-pendulum. There was a very significantly positively correlated between bending pole degree and the vertical velocity of the moment at left hand leave pole. The flight height is proportional with bending pole degree. The CM-MAX of Chinese athletes has a big difference with bar height, so need to improve the technique of clear the bar.
