| Abstract(in English) | Throwing a ball is a very important task in baseball. To throw a ball into a given target, we must accurately select the initial state of the ball, the position, speed, and throwing direction at ball release. There are two ways in the control of these variables; the first solution is to learn a desired value set for these state variables through leaning and try to adjust the variables to the desired values. Another solution is to allow the variance of each variable observed in every trial but compensate for the values each other in a cooperative manner in order to accomplish the throwing task. The purpose of this study is to elucidate the knack of the ball throwing task by observing how good throwers select the state variables in throwing. We measured ball trajectories thrown by subjects sitting on a chair into a given target and analyzed if cooperative change among the state variables is observed. The result clearly shows how these variables are working: the variance of the release point is suppressed and cooperative change in the initial speed and the throwing direction of the ball was observed in good throwers. |
