타격 중 시선 선행이 신체의 운동학적 변인에 미치는 영향

Abstract

The purpose of this study was to examine the differences in center of gravity in the human body and kinematics variables of the tennis racket at hitting through the ball with forehand stroke. Seven experienced college tennis players performed tennis forehand strokes in quiet eye and eye movement. Four digital cameras was used to measure the change of center of gravity and velocity and displacement and velocity of tennis racket. The results of this study revealed as follows; (1) players’ center of gravity in movement showed similar swing pattern to those reported for speed of movement. Comparing to eye movement, quiet eye was lower in movement displacement and velocity; (2) although there was a similar pattern relative to movement displacement and velocity of the tennis racket, the vertical displacement movement and speed in eye movement was lager than those of quiet eye at hitting ball. The findings of this study were that eye movement for tennis forehand stroke contributed to better body’s center of gravity and the vertical velocity of racket.
