为了比较不同级别男子跳远运动员起跳阶段“身体姿位”参量的异同，采用文献资料法、摄像解析法和数理统计法，对男子跳远一、二级运动员起跳阶段的着板角、蹬离角、起蹬夹角、腾起角以及起跳腿髋关节、膝关节在三个运动时相（着板时、最大缓冲时、蹬离时）的角度或运动幅度进行比较。结果表明：“身体姿位”参量是影响动作技术效果的最基本因素；一级跳远运动员的着板角度、蹬离角度、着板时膝关节角度、最大缓冲时刻膝关节角度、蹬离时膝关节角度以及髋关节伸展幅度均大于二级运动员的，腾起角之间的差异不具备统计显著性；“高跳型”是当今世界跳远技术的发展趋势，在细节方面，要求运动员避免髋关节的屈曲幅度，适当增大着板角度、蹬离角度、着地时膝关节角度、最大缓冲时刻膝关节角度和蹬离时膝关节角度。

In order to compare body posture parameters of male athletes in different levels, by using the methods of literature review, video analysis,mathematical statistics, this paper compared the body posture parameters,which are consist of pedal angle, tread from angle, from centrifugal moment - to-radial-moment angle, takeoff angle, the angle or range of motion of knee and hip joints in three-phase （pedal, maxi mum buffer, tread from）. The results showed that body postural parameters are the basic factors, which affect the motion technology consequent. The takeoff angles do not have statistical significance, while other angles of the first class male jumpers are bigger than the second class male jumper. High-jump-type is now the leading technology, in the details, it is appropriate that the jumpers should avoid hip flexion, moderately increase pedal angle,take-off angle,knee angle in three-phase.
