The purpose of this study was to investigate the effect of the characteristics of baseball bat on swing. The subjects were five skilled baseball players. It was provided an experimental bat to be able to set up nine conditions for the position of the center of gravity and the mass. The behaviors of the bat during their swings were analyzed with DLT method using two cameras, and the three-dimensional kinematical data were calculated at the impact to ball and during swinging the bat. The main results were as follows; 1)There were a few cases in which the angular velocity of bat at the impact was affect to the position of center of gravity or the mass on bat. 2)In the case in which the characteristics of bat was affect to the swing speed at the impact, there had a favorably effect on the behavior of bat during swing. 3)It was not recognized that the characteristics of bat affected to the accuracy at the impact.
