골프 스윙 시 수직방향 지면반력의 증가 원인에 대한 분석

Abstract

In this study, we try to figure out what factors make magnitude of vertical ground reaction force increase during golf swing. We do some experiments with four teaching pros who teach golf to others. Using force platform and motion capture devices, we measure motion data and force data of subjects’ swing. Each subject iron 7 and driver, we measure First, we compare vertical ground reaction force to force generated by swinging club. Even though magnitude of the force generated by swing is about ten percentage of body weight, but we figure out that it is not a major factor about increase of vertical ground reaction force because the tendency does not match between them. So ,secondly, we compare body inertia force to . Because we don’t know body weight percentage of each subjects specifically, using acceleration of each segments we calculate coefficients which matches vertical ground reaction force well. These coefficients are related not only mass of each segments, but also related strategies of swing. The results are in this paper. Each subjects shows different coefficients. Even if same subjects, the coefficient is not same when using different club.
