The purpose of this study was to clarify predictive visual patterns of skilled table tennis players during forehand rallies. Collegiate male table tennis players (n = 7) conducted forehand rallies at a constant tempo (100, 120 and 150 bpm) using a metronome. In each tempo condition, participants performed a total of 30 strokes (three conditions). Gaze fixation time, gaze targets and saccade eye movements were detected by video footage of an eye tracking device. We found that participants gazed at a ball approaching them only 20 % of the total rally time. Participants tended to gaze at the ball when the opponent hit the ball and move their gaze away from the ball after that. Furthermore, saccades were directed toward the opposite side of the court including the opponent after tracking the ball. These findings suggest that focusing on the opponent motion is important for successful forehand table tennis rallies. Taken together, skilled table tennis players are likely to use unique visual patterns for interceptive sports players to estimate spatiotemporal information about the ball.
