Kinematic And Comparative Study Of Four Type Upperlimbs Techniques Of Backhand With Reverse Side Of The Penhold Racket In Table Tennis

Kinematic analysis of the innovational technique of backhand with reverse side of the penhold racket was made in six Liao ning provience team players by adopting exercise-biomechanical analysis with the DLT photography.Its technical cruxes,technical features and the kinematic parameters concerned were attained.So as to provide theoretical basis for the populization and improvement of this trchniques.Draw the conclusion as follows:1. The technique of pen-hold with reverse side comforts to the theory of whipping.2. The rotary muscle of upper limbs do main favour in speeding the racket .3. As basic section ,the trunk velocity and effect influence the quality of upper limbs directly.4. Expect side-pick,upperlimbs inner muscles contract in preparation ;All types'outside muscles shrink in loop.5. The index of wrist is mutually related with velocity of racket obviously.Though its moving distance is short,the wrist is key factor influencing the velocity of racket.
