프로골프선수의 드라이버 스윙 동작에 따른 지면반력 특성 분석

Abstract

The purpose of this study is to identify the weight transfer form of driver swing motion by comparing with preceding study and analyzing kinetic variables with use of force plate in case of male pro-golf players. For this, force plate at the moment of driver swing was measured with 3 golfers playing today as the members of KPGA. Also, the swing motion was video-taped with 2 high speed video cameras (180fields/sec) synchronized with force plate. Here are the conclusions about this study. First, the totally time required for driver swing is 1.78sec for S1, 1.15sec for S2, and 1.57 sec for S3. The time required for back swing is 0.97sec for S1, 0.93sec for S2, and 0.92sec for S3. The time required for down swing is 0.32sec for S1, 0.30sec for S2, and 0.28 sec for S3. It shows that the time ratio of back swing vs down swing is 3 to 1. Second, about 62-98% of both(right and left) to vertical direction leans toward right foot at the moment of impact. Lately the center of pressure at the moment of top swing once moved rather back of the feet than at the moment of address, and then moves forward gradually.
