The main purpose of this study was to analyze the release motion of Spinner using biomechanics methods and provide a reference for coach and players during training. The subject in this study was a top female bowling player in Taiwan. The last step of Spinner was examined using the Peak Performance video motion analysis system to discover the characteristics of motion. The accepted digital data carries out smooth processing to reduce errors by using a program of Butterworth. Then it starts to analyze and discuss after it gets the reconditioned data. Results were as follows: At the peak point of backward swing, the vertical height from the center of the ball to the ground was 1.34±0.01 meters with the height of 78.82%. The angle of the shoulder was 82±2.5 degrees and the angle of the elbow was 161.35 degrees. During release, the vertical height was 0.13±0.01 meters with the height of 7.65%, the angle of the shoulder was 48.00±3.64 degrees and the angle of the elbow was 160.71 degrees. The total time from the peak of backward swing to release was 0.50±0.02 seconds. During forward swing, the vertical displacement was 1.22±0.01 meters with the height of 71.76%, and the horizontal displacement was 2.00±0.08 meters. The timing of maximum speed at the joints of the upper limb corresponds to the principle of kinetic chain. The average release speed was 8.65±0.09 m/s which was very close to the speed in horizontal direction. The investigate data of analysis, during release of vertical height from the center of the ball to the ground, speed of the hand, angle of the shoulder without difference, evidence subject in three dimension include stability and coordinate.
