Abstract
Golf is a sport that can be enjoyed by people of all ages. The appeal of golf is not only the competition of scores, but also the feeling of satisfaction that comes from hitting an accurate shot. For accurate shots, it is necessary not only to use clubs suitable for the golfer’s swings, but also to improve swinging motion. Many golfers wish to improve their swing, but it is difficult to do so easily because the swinging motion is complex and because each golfer swing is unique. Therefore, the purpose of this study is to propose a golf swing improvement method for beginners and intermediate golfers based on the hypothesis that beginners and intermediate golfers do not understand the coordinated movements of the body during the golf swing. First, we measured the basic movements related to the golf swing, called "exercise movements," of beginners and intermediate players. After the exercise movements were measured, the instructor provided instruction to improve the exercise movements. After the improvement of the exercise movements was confirmed, singular value decomposition was performed on the exercise movements before and after the improvement, the exercise movements were decomposed into multiple cooperative movements, and the original and improved cooperative movements were compared. Finally, we compared the swing movements before and after the exercise movements and investigated the effect of the improvement of the exercise movements on the swing movements.
