The purpose of the study was to achieve a 3D Motion capture analysis using Kwon3dX program. And Step 4 and Step 5 the kinematic differences between the mean and standard deviation were calculated using the SPSS 21.0 program. Through the independent t-test was the difference between the two types of verification. The conclusion of this study are as follows.
First, bowling throwing motion during the total time showed a statistically significant difference (p<.05).
Second, bowling throwing motion during the horizontal displacement showed a significant difference in E2, E3 and E5 (p<.05), vertical displacement showed a significant difference in E2 (p<.05).
Third, the horizontal velocity of the pitching action at bowling CM (center of mass) showed a significant difference in the E2 and E5 (p<.05), the vertical speed of the CM was found no difference.
Fourth, bowling throwing motion during the stride showed a significant difference in total distance (p<.05).
Fifth, bowling throwing motion during the horizontal displacement of the ball showed to have moved the forward direction, depending on the throwing motion progresses. And vertical displacements showed to be the highest in the E4 lowest in E5.
Sixth, bowling throwing motion upon release when the angle of tilt with lower body joints showed no significant differences in the velocity of the ball showed significant differences (p<.05).
In conclusion bowling throwing motion step 4 showed a long distance in a push away phase 5 step differences were seen in a long distance down swing phase. Horizontal displacement in this case also was seen as affected. Step 4 S tep 5 and all appeared to throwing the ball showed a long s tride in the last step. These causes are to throwing the ball stable when released in the last step. And in order to make a fast, accurate and powerful throwing ball velocity when the forward swing.
