This research processes the six players’ analysis of angular replacement,angular speed,and angular acceleration of carpus motion data at the moment of picking up photos with high-speed photography skills. After picked up at the rate pf 1000 HZ sampling frequency and 1/4000 second snapshot of high-speed photographing,these data are shown as follows by means of Kwon three-dimension digital software analysis system processing: 1. In terms of the motion of hand-carpus joints while sinker pitching,these averages of Angular Displacement(A.D.) and 0.96. 2. In terms of the motion of hand-carpus joints while sinker pitching,these averages of Angular Speed(A.S.)and(S.D.), Linear Velocity(L.V.)and(S.D.),Linear Acceleration (L.A.)and(S.D.)are respectively 2033.65 degrees per second and 0.96,93.67 meters per second and 1.836,310.371 meters per second and square and 6.0851. 3. In terms of the motion of hand-carpus joints while sinker pitching,these averages of Initial Speed(I.S.)are respectively 75.37 kilometers per hour and 0.691.
