The aim of the present study was to examine changes in weight transfer during golf shots from flat, uphill, and downhill lies. Twelve male amateur golfers with a mean handicap of 1.6 ± 2.4 hit a total of 30 golf shots from flat, downhill, and uphill lies. A computer assisted rehabilitation environment (CAREN) was used to collect 3D kinematics and kinetics and a Foresight GC2 launch monitor was used to measure performance outcomes (ball speed, launch angle, azimuth, side spin, and offline displacement). The mean position of the centre of pressure moved approximately 9.4% closer to the front foot for downhill lies and approximately 8.9% closer to the back foot for uphill lies. The speed of the ball was not significantly affected by the lie, but the distance the ball travelled was. An uphill lie encourages spin of the ball to the left, and may increase the risk of playing a hook shot.
