In many sports, it can be important to know when to speed up movements and when to slow them down. This muscle control requires a student to make many different judgments. For example, when catching a ball, a student needs to process information that is largely visual and spatial, e.g., judging the angle at which the ball is coming, its speed, and its estimated arrival time. The student then uses this spatial information to coordinate running at the appropriate speed and positioning his hands to catch the ball.
Other activities, such as running or swimming focus on spatial information that relates more to where the student is in space.
While engaged in a sport, a student is constantly receiving feedback about his position in space and whether he needs to slow down or speed up his movements. By responding to this feedback, for example, by adjusting speed to catch a ball or turning at the right time at the end of a swimming lane, a student can often increase his success in a sports activity.
