| Abstract: | Through the mechanical analysis on the displacement of boby's major joints (the shoulder,elbow and wrist) in Zhou Hong's service the feature of whipping action during hitting ball and the reason of higher Ballspeed are found out. There is three-segments whipping action by the shoulder,elbow and wrist,with the waist serves as the kinetic axis in Zhou Hong's service technique so the wrist gains a larger acceleration. In most of other players technique there is two-segments whipping action by the elbow and wrist, with the shoulder serves as the kinetic axis. |
