PURPOSE
The purpose of this paper is to describe a method utilized to measure vertical head and eye movements and gaze positions of baseball batters and to report the initial findings generated with this method.
METHOD
Two former collegiate baseball players participated. Subjects batted balls from a pitching machine.
RESULTS
Responses were similar for the two subjects. The head demonstrated a small upward rotation followed by a downward rotation. The eye was rotated opposite to the head throughout portions of the swing while gaze was directed below the ball (more for one subject than the other) for much of the pitch trajectory.
DISCUSSION
These data align with previous assertions that in baseball batting, players attempt to keep pitched balls in a constant egocentric direction.
目的
本文旨在描述一种用于测量棒球击球手头部和眼睛垂直运动以及注视位置的方法，并报告使用该方法得出的初步研究结果。
方法
两名前大学棒球运动员参与其中。受试者击打投球机投出的球。
结果
两名受试者的反应相似。头部先有一个小幅度的向上旋转，随后是向下旋转。在挥棒的部分过程中，眼睛的旋转方向与头部相反，而在大部分投球轨迹中，注视方向指向球下方（一名受试者比另一名受试者更明显）。
讨论
这些数据与之前的观点一致，即在棒球击球中，球员试图使投出的球保持在一个恒定的以自我为中心的方向上。
