The top players of field hokey experientially know that high restitution area of their hokey stick exists not on the head but on the position slightly shifted to grip end. They would have to swing the stick horizontally with low posture to hit the ball near the area when strong and high speed balls were needed in the game. Therefore, we have been developing a new hockey stick that has high restitution area on the head. The mass distributions of sticks affect the positions of the 1st modal node of vibration and center of percussion has been found. The area on the high coefficient of restitution may be related to the positions of the 1st modal node of vibration and center of percussion. In this study some experiment using sticks with the various positions of the modal node and the center of percussion controlled by the mass distributions has been carried out. Furthermore a hockey ball model was newly proposed for FEM analysis. The results of the FEM simulation closed on the results of our previous experiment.
