Abstract

The aim of this study was determine to effect of shaft length and physical condition on golf driving performance(head speed, distance and direction). A range of drivers with length between 44 inch, 45 inch and 46 inch limit imposed by R&A rules limited were assembled and evaluated. Club head speed and drive distance and accuracy were determined three category 27 PGA pro golfer (handicaps 0, and height $170cm{\geq}171-175{\geq}175-180cm$) who golf performance. As a results follow : Head speed was significantly difference with 44, 45 between 46inch(p<.01). Distance was significantly difference with 44 between 46inch(p<.05). And direction was significantly difference with 44, 45inch between 46inch(p<.05). Head speed according to height was general similarity among shaft length in 170cm, 171-175cm. Distance were general similarity among shaft length in 170cm, and significantly difference with 44inch between 46inch in 171-175cm(p<.01), and significantly difference with 45inch between 46inch in 176-180cm(p<.05). Direction were significantly difference with 44inch between 46inch in 170cm(p<.05), but do not significantly difference with 44inch between 46inch in 176-180cm, 176-180cm. These results show that shaft length and height can affect head speed, distance and direction.

본 연구의 목적은 드라이버 샤프트 길이와 신체적 조건이 헤드스피드와 비거리 및 방향성에 미치는 영향에 대하여 분석하였다. 연구에 참여한 대상은 핸디캡인 0인 남자 프로골퍼 27명을 대상으로 신체적인 조건은 키($170cm{\geq}170-175cm{\geq}175-180cm$)로 하였고, 연구에 사용한 드라이버 길이는 44 인치, 45 인치, 46 인치로 하였다. 골프 수행력은 헤드스피드와 비거리 및 방향성을 종속변인으로 설정하여 분석하였다. 연구 결과 일반적인 헤드스피드는 44, 45인치와 46인치 간에는 유의한 차이가 나타났다(p<.01). 비거리에서는 44인치와 46인치 간에 유의한 차이가 나타났다(p<.05). 방향성에서는 44, 45인치와 46인치 간에는 유의한 차이가 나타났다(p<.05). 키에 따른 헤드스피드는 170, 171-175cm에서는 클럽 간에 대동소이하였고, 176-180cm 44인치와 46인치 간에 유의한 차이가 나타났다(p<.01). 키에 따른 비거리는 170cm에서는 클럽길이 간 대동소이하였고, 171-175cm에서는 44인치와 46인치 간에 유의한 차이가 나타났으며(p<.01). 176-180cm 45인치와 46인치 간에 유의한 차이가 나타났다(p<.05). 키에 따른 방향성에서는 170cm에서 44인치와 45인치 간에 유의한 차이가 나타났고(p<.05), 45, 46인치에서는 키와 상관없이 클럽 간 유의한 차이가 없는 것으로 나타났다. 결론적으로 드라이버 샤프트 길이 및 키에 따른 골프 수행력에 영향을 미치는 것으로 나타났다.
