摘　　要：排球跳发球技术对运动员身体素质以及技术水平有着较高的要求。意大利女排埃格努是目前大力跳发球的代表人物。从南京实地现场拍摄埃格努的大力跳发球,通过DARTFISH软件解析埃格努具有代表性的三次跳发球的助跑步幅速度、抛球动作各环节参数等,发现:埃格努大力跳发击球时其空中姿态成“<”型用力最好;在空中击球阶段转体幅度与击球前的引臂发力成正比;击球时膝关节适宜的屈伸角度可以使肌肉用力最大化并获得较大的动能。In terms of volleyball jump serve skill,there is a high demand on athletes’physical quality and technical level.Due to its complex technology,Chinese women’s volleyball team has a poor grasp of the powerful jump serve skill.Egonu,an Italian volleyball player,is the representative figure of jump serve.We shot her forceful jump serve in Nanjing.Through DARTFISH software,we analyzed her parameters in run-up stride speed and throwing ball movement.It is found that when the body posture in the air is like a less than symbol,the force is the best;in the air phase of hitting the ball,the turn amplitude is proportional to the arm force before hitting the ball;the proper flexion and extension angles of the knee joints can maximize the muscle force and achieve greater kinetic energy.
