드라이버 클럽 백스윙 시 어깨회전, 골반 회전 각도가 헤드스피드에 미치는 영향

Abstract

This study set out to measure and analyze the effects of shoulder and pelvis rotation angles on head speed in a back swing, which is known to have close connections with the driver head speed and club distance, with ten superior male and female golfers each that were active in League 1 and 2 tours of Korea Professional Golf Association and Korea Ladies Professional Golfers Association. The findings led to the following conclusions: 1. In a driver club back swing, the male and female subjects recorded a mean shoulder rotation angle of 108.73°±9.59° and 115.73°±6.05°, respectively. The female golfers had a greater shoulder rotation by about 7° on average in a back swing than their male counterparts. The male and female golfers recorded a mean pelvis rotation angle of 54.65°±6.71° and 54.75°±7.90°, respectively. There were few differences in the pelvis rotation angles between the male and female golfers. 2. The present study analyzed correlations among the shoulder rotation angle, pelvis rotation angle, and head speed of the male golfers in a back swing and found no significant correlations among them. The female golfers showed significant negative correlations between their shoulder rotation angle and head speed(r= -.786, p<.01).
