The purpose of this study is to analyze the kinematics of the goal ball turning throwing motion, and the conclusions are as follows. First, the total time for goal ball turning and throwing motion was 1.82 s, 76.95 % in P1 and 23.02 % in P2. Second, it was found that the COM (center of mass) left and right displacement of the goalball turning throwing motion moved leftward from P1 (E1~E2) and moved to the right from P2 (E2~E3). COM forward and backwark displacement Moved to the forward according to the progress of the event. COM vertical displacement moved downward according to the progress of the event. Third, the COM left and right velocities of the goal ball turning throwing motion showed the fastest velocity from E3 to the right, and the COM forward and backward velocities showed the fastest speed from E2 to the forward. COM vertical velocity showed the fastest downward velocity at E2. Fourth, when the goal ball turning throwing motion was released, the velocity of the ball was 12.00±0.88 ㎧, and the stride width was 1.09±0.12 m. Fifth, the body segment’s angular momentum at the time of release of the goal ball turning throwing motion was found to be the largest in the trunk. And the upper arm, forearm, and hand segment of the upper limb all showed greater angular momentum than the left. In the case of the lower extremities, the right thigh and foot segments showed greater angular momentum than the left, but the left shank segment showed greater angular momentum than the right. Sixth, when the goal ball turning throwing motion was released, the ground reaction force of the forefoot showed the force in the right direction, the rear direction, and the vertical upward direction, and at this time, the large force was in the order of Fz, Fy, and Fx.
