Description

When batting in baseball, the batter requires a complex set of skills in order to hit the ball. This is because the released ball travels at different speeds and in different positions until it reaches the irnpact point. The batter not only processes information about the ball before starting the swing but also uses information on the ball after starting the swing. This study compared the coordination and coordinative structure of swings by expert and novice batters under a variable condition and a constant condition. In the variable condition, the ball was released randomly from two batting machines set at different speeds, while in the constant condition the ball was released repeatedly from the same batting machine. Three baseball players participated in this experience as expert players and three graduate students participated as novice players. Their movement were recorded by three cameras, and analyzed using 3-dimensional kinematics. The results indicate that the experts adapt when they start to step to the timing of a fastball and then wait after landing in the variable condition to correct the hitting movement. By contrast, the novices change only when they start to step to match the ball speed.
