골프 스윙 시 족저압 분석을 통한 힘의 변화 및 중심이동 변화에 관한 연구

Abstract

This study analyzed the plantar foot pressures and weight transfer patterns during golf swing for three professional golfers as well as three amateure golfers. The tester let the experienced and inexperienced golfers hit the ball 50 times each and selected the ten good and satisfactory swing by the golfers themselves. The equipments are plantar foor pressure measuring system(PEDAR-X system) and digital motion capture system(EVaRT 4.2 Software, Eagle4 digital system and Hawk digital system). The conclusion is that there are distinct difference of plantar foot pressure between professional golfers and amateure golfers during finish period. the changes of weight transfer shows valuable difference at P3 block for X axisduring iron swing. and for driving, there was valuable difference at P2, P3, and P4 for Z axis and at P2 block for Y axis. Generally for golf swing, the movement of up and down is a key factor of accurate impact but there was no valuable difference between professional and amateur golfers statistically. Between professional and amateur golfers there was no difference of weight transfer at P1 block but when driving there was difference of weight transfer toward the direction of ball moving between professional golfers and amateur golfers.
