Many professional golfers and researchers say that lower limbs during golf swing is important to make fast club head speed. Electromyography or motion capture system have to be used to measure how much lower limbs active, however, those device can obstruct swing motion. On the other hand, measuring vertical ground reaction force (vGRF) can minimize disruption. In this study, we wanted to roughly calculate how much lower limbs contribute during golf swing using pattern of vGRF. To examine this, we measured motion data and vertical ground reaction forces of subjects using infrared motion capture system and two force platforms during golf swing using driver. The subjects were composed by 13 male right-handed golfers who have various skill level from 50-handicapped to KPGA professional golfers,and analyzed correlation between vertical acceleration of each body segments and vGRF. As a result, in low skilled group, correlation between lower limbs motion and vGRF is low. In contrast, high skilled group showed high correlation. In conclusion, if pattern of vGRF of various skill leveled golfers are collected, we can roughly estimate contribution of lower limbs during golf swing not using motion capture, but measuring vGRF.
