court. In the laboratory setup subjects sat 4 m from a projection screen. They were instructed to react as quickly and accurately as possible in response to near life-size images of tennis forehand strokes. The reaction was made by pressing a keyboard button after which they notified the direction of the stroke. In the field test subjects were required to physically respond on-court to actual forehand strokes by moving to the right direction. Their responses were filmed from the front and the opponent from the right hand side using two video cameras (50 Hz). The synchronization of the video clips and the analysis of the decision time in response to the ball-racket contact were analyzed using Dartfish-software. Decision time (ms) and accuracy (%) were measured before and after the training period in both test conditions. Ttest was used to detect changes from preto posttest and the differences between the groups.
