 note = {The purpose of this study was to compare the difference in spatial control of tennis footwork in relation to the difference of players’ skill level. Intermediate (N=5) and novice (N=4) male tennis players volunteered to take part in this study. Subjects hit a ball ejected from a ball machine with a forehand groundstroke toward straight as fast as possible. At impact,some subjects used open stance, the others used closed stance. Intermediates hit a ball closer to the net and at a higher position than novices. The ball speeds for intermediates were higher than those of novices and intermediates made fewer mistakes
than novices. Intermediates using closed stance showed lower standard deviations of the last two foot placements than novices. The significant correlations between an impact position and the last two or three foot placements were observed in intermediates. On the other hand, the significant correlation was found only between an impact position and the last foot placement in novices. These results indicated that intermediates were able to anticipate an impact position earlier and more accurately than novices, and intermediates adjusted their footwork based on their spatiotemporal anticipation.},
