On the Tactical Significance of Game Situations in Anticipating Ball Trajectories in Tennis

Abstract

It is hypothesized that live playing situations preceding an opponent's strokes in tennis have sufficient significance to provide expert players with anticipative cues to estimate accurately the spatiotemporal characteristics of oncoming ball trajectories. Seven participants (all expert tennis players) had to watch two players opposed in high, moderate, and low tactical significance situations terminated by a stroke delivered by one of the two players in the direction of the participants. The participants' vision was occluded 100 ms after the stroke, and they had to indicate the zone reached by the ball at the moment of its rebound. Results showed that the essential anticipative information is contained in the view of the opponent's stroke movements, whatever the tactical significance of the situation.
