以12名江苏女子排球队二线运动员为研究对象，采用高速摄像对12名队员的3次大力跳发球和3次跳飘发球技术分别进行拍摄，利用运动分析软件对录像进行解析，探讨江苏省女子排球运动员大力跳发球与跳飘发球间的运动生物力学差异。研究结果显示：大力跳发球的球速、起跳后COM水平位移、起跳高度、击球高度、COM速度等数值均要高于跳飘发球。另外，运动员在进行大力跳发球时上肢的线性速度显示较高值，从而对挥臂的最后鞭打动作提供有利的初速度。结果说明大力跳发球虽然具有一定的失误风险，但是具有较强的攻击性，给接发球方带来很大的压力。

Basing their research objects on 12 second line players in Jiangsu Women’s Volleyball Team, the authors used a high speed video camera to respectively shoot the technical moves of 3 spiking jump serves and 3 floating jump serves made by the 12 players, dissected the video by using a piece of motion analysis software, analyzed biomechanical differences between a spiking jump serve and a floating jump serve made by the female volleyball players from Jiangsu province, and revealed the following findings: a spiking jump serve produced higher values than a floating jump serve in terms of ball speed as well as COM horizontal displacement, jump height, spike height, ball hitting height and COM speed after jump; moreover, the linear speed of the upper limb was higher when such a player was making a spiking jump serve, which resultantly provided a favorable initial speed for the last whipping move made by the swinging arm. Conclusion: although there is a certain risk of failure in a spiking jump serve, it is more aggressive, and will bring great pressure to bear on the serve receiving player.
