The purpose of this study is to investigate the hitting performance of the field hockey sticks. First of all, the basic physical properties such as moment of inertia, bending stifiness, stifiness distribution and vibration property were measured in eight selected hockey sticks. Then, hitting test was carried out by using the golf swing robot in order to investigate the maximum hitting point which has close relationship to performance in shooting and passing actions. As a result, some basic and remarkable data of the stick properties were obtained as follows, (1) The moment of inertia depended on mass and center of mass. (2) FRP sticks were staffer than wooden sticks. (3) The node of the first mode was around 160mm from the toe of the stick head. (4) In robot hitting test, the ball speed increased at the point of around 180mm than at the head where most players usually hit the ball.
