本研究旨在探讨乒乓球运动员在击球过程中的注视和头部运动的特性。大学乒乓球运动员（n = 12）进行了一个熟练的实验者发射的球的两次击球。共进行了10次试验的实验任务。通过眼动跟踪装置记录的图像分析球、凝视、头部和眼睛的水平和垂直运动。结果表明，参与者并不总是保持他们的目光和头部的位置在整个球的路径。我们的研究结果表明，乒乓球运动员往往在最初的球跟踪阶段盯着球。此外，有一个显着的负相关关系，尤其是在垂直方向的眼睛和头部的位置。这一结果表明，水平VOR比垂直VOR在乒乓球击球过程中的球跟踪相对抑制。最后，多元回归分析显示，头位对注视位的贡献显著高于眼位。这一结果表明，在中风期间的凝视位置可能与头部位置，而不是眼睛的位置。综上所述，头部运动可能在乒乓球击球过程中保持球在恒定的自我中心方向上发挥重要作用。
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 relatively suppressed than vertical VOR in ball-tracking during table tennis forehand stroke. Finally, multiple regression analysis showed that the contribution 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.
