In baseball, higher bat velocity and the bat control are required for the successful hitting. Although kinematical factors related bat velocity have been studied, the knowledge about hitting kinematics related ball-bat contact precision is limited. The aim of this study was to examine the hitting kinematics for precise ball-bat contact in collegiate baseball hitters. Ten collegiate baseball field players completed 20 swings at a ball on the baseball tee, and their joint angles were calculated. The results indicate that hitters with lower precision in ball-bat contact might have excessive variability in joint angles in trail arm.
