골프 아이언 스윙 시 어드레스 자세에서 볼 시선 위치에 따른 구질 및 근 활성도 분석

Abstract

This study was carried out to identify the relationship of ball quality, dynamic factors and muscle activity, according to the change of gaze position of the golf ball in case of iron shot, targeting 10 golfers of KPGA(Korea Professional Golf Association) as subjects and reached the following conclusions.BR First, the change of gaze position of the golf ball on address posture in iron swing affected the distance, head speed, ball speed and smash factor, but there were no statistically significant difference.BR Second, for all subjects except subject E and J, the change of gaze position of the golf ball on address posture in iron swing affected the change of ball quality.BR Third, the change of target position of the golf ball on address posture in iron swing affected the change of activity of brachioradial muscle, muscle flexor carpi radialis, biceps brachii, and triceps brachii, but there was no statistically significant difference.BR The swing for the intended change of ball quality during the golf game can give mental effect which may cause good results but may produce the contrary results. Thus, the results from this study that the change of gaze position focusing on the golf ball leads to the change of ball quality and affects the dynamic data of distance and the ball, will be able to be basic data for the easy change of ball quality as necessary during the game and later, the study for the difference of muscle and nerve coordination according to the change of gaze position of golf ball seems to be required.
