골프 퍼팅의 인적 오류에 의한 방향오차 최소화에 관한 연구

Abstract

Golf is rapidly becoming a popular sport around the globe. Accurate putting is a key factor in keeping a low score in the game of golf. However, anxiety and/or inexperience can make all golfers miss putts on a regular basis. Most of these misses occurred can be attributed to either pulling the putter toward one's body or pushing it away from one's body during the putt. Two conditions must be met in order to putt in the correct direction. The first is that the hitting surface must be aligned perpendicularly to the intended path and the second is that the ball must be hit by moving the putter head parallel to the intended path. The proposed putter design by this study has a convexly curved shape of the hitting surface. The curved shape of the face decreases the directional deviation even when the ball makes contact away from the center of the rotated head. Statistical analysis has been done to show the direction-correcting effect and a field test was conducted using human subjects on real greens to see how much improvement can be obtained from using a curved-face putter. The test confirmed that using a proposed putter improved not only the success-rate but also the overall accuracy. This kind of analytic approach will be necessary to enhance athlete ability in sports and can be applied to design of better sporting equipments.
