The purpose of this study was to clarify the properties of gaze and head movements during forehand stroke in table tennis. Collegiate table tennis players (n = 12) conducted forehand strokes toward a ball launched by a skilled experimenter. A total of ten trials were conducted for the experimental task. Horizontal and vertical movements of the ball, gaze, head and eye were analyzed from the image recorded by an eye tracking device. The results showed that participants did not always keep their gaze and head position on the ball throughout the entire ball path. Our results indicate that table tennis players tend to gaze at the ball in the initial ball-tracking phase. Furthermore, there was a significant negative correlation between eye and head position especially in the vertical direction. This result suggests that horizontal VOR is suppressed more than vertical VOR in ball-tracking during table tennis forehand stroke. Finally, multiple regression analysis showed that the effect of head position to gaze position was significantly higher than that of eye position. This result indicates that gaze position during forehand stroke could be associated with head position rather than eye position. Taken together, head movements may play an important role in maintaining the ball in a constant egocentric direction in table tennis forehand stroke.
本研究旨在阐明乒乓球正手击球过程中注视点和头部运动的特征。大学生乒乓球运动员（n=12）向由熟练实验者发射的球进行正手击球。对于实验任务共进行了十次试验。从眼睛跟踪设备记录的图像中分析球、注视点、头部和眼睛的水平和垂直运动。结果表明，参与者在整个球路径中并不总是将注视点和头部位置保持在球上。我们的结果表明，乒乓球运动员在初始球跟踪阶段倾向于注视球。此外，眼睛和头部位置之间存在显著的负相关，尤其是在垂直方向上。这一结果表明，在乒乓球正手击球过程中的球跟踪中，水平 VOR 的抑制程度高于垂直 VOR。最后，多元回归分析表明，头部位置对视点位置的影响显著高于眼睛位置。这一结果表明，正手击球过程中的注视点位置可能与头部位置而不是眼睛位置有关。综上所述，头部运动在保持乒乓球正手击球过程中球在恒定的自我中心方向上可能起着重要作用。
