The purpose of this study was to clarify the temporal coordination between gaze, head, and arm movements during forehand rallies in table tennis. 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 30 strokes (a total of 90 strokes). Gaze, head, and dominant arm (shoulder, elbow, and wrist) movements were recorded with an eye-tracking device equipped with a Gyro sensor and a 3-D motion capture system. The results showed that the effect of head movements relative to gaze movements was significantly higher than that of eye movements in the three tempo conditions. Our results indicate that head movements are closely associated with gaze movements during rallies. Furthermore, cross-correlation coefficients (CCs) between head and arm movements were more than 0.96 (maximum coefficient: 0.99). In addition, head and arm movements were synchronized during rallies. Finally, CCs between gaze and arm movements were more than 0.74 (maximum coefficient: 0.99), indicating that gaze movements are temporally coordinated with arm movements. Taken together, head movements could play important roles not only in gaze tracking but also in the temporal coordination with arm movements during table tennis forehand rallies.
本研究旨在阐明乒乓球正手对攻中注视、头部和手臂运动之间的时间协调性。7 名大学生男性乒乓球运动员使用节拍器以恒定的节奏(100、120 和 150 bpm)进行正手对攻。在每个节奏条件下,参与者进行 30 次击球(共 90 次击球)。使用配备 Gyro 传感器和 3D 运动捕捉系统的眼动追踪设备记录注视、头部和优势手臂(肩部、肘部和手腕)的运动。结果表明,在三个节奏条件下,头部运动相对于注视运动的影响明显高于眼球运动。我们的结果表明,在对攻中头部运动与注视运动密切相关。此外,头部和手臂运动之间的互相关系数(CCs)超过 0.96(最大系数:0.99)。此外,在对攻中头部和手臂运动是同步的。最后,注视和手臂运动之间的 CCs 超过 0.74(最大系数:0.99),表明注视运动与手臂运动在时间上是协调的。综上所述,头部运动不仅在注视跟踪中,而且在乒乓球正手对攻中与手臂运动的时间协调中可能发挥重要作用。
