|
This study analyzed performance according to kick point and stiffness of Soft- shaft. This research team developed soft- as a new fusion sports with similar motions with golf and it can be learned safely for all age groups in 2002. The head of Soft- club is made of zinc alloy and has a mesh or a grid structure, and shaft uses carbon graphite to reduce the total weight of the club. To improve carry distance and to assure consistency of a ball during Soft- swing, this study manufactured shaft with various kick points (low, middle and high) and stiffness (stiff, regular, lady, morelady) and analyzed a swing motion with characteristics of each shaft presented in a dynamic condition such as a ball’s speed, a head’s torsion angle and a ball’s deviation with ProAnalyst program through a high-speed camera taking pictures using a swing machine robot system(Robo-7). From all of the results, this study determined an appropriate shaft of Soft-.
