The purpose of this study was to determine the characteristics of the kinematics in golf swing for the flat lie, uphill lie and downhill lie of 10 degrees. Ten right-handed professional golfers were selected for the experiment and the 7 iron club was used. We used four forceplates to measure GRF and synchronized with the three-dimensional motion analysis system(VICON). The slopes could have negative effect on the coiling of lower limbs during back swing because of no good weight movement. The slopes could have negative effect on making maximum momentum because of interrupting the blocking of the lower limbs to minimize the dispersion of the weight and the release of the lower limbs after the impact during down swing, It might be very important to select an appropriate dub for the distance and accuracy with the slopes because of the negative effect on the maximum club head velocity.
