Skill analysis of the wrist release in golf swing to utilize shaft elasticity

In this study, skill of the wrist turn in golf swing was analysed by using a three-dimensional dynamic model including three dimensional shaft vibration. It is generally noticed that professional and expert golfers try to match shaft flexibility with their swing style, and that the property of the expert swing appears in the wrist turn as a 'natural' or 'late' release. Thus, the relationship between the timing of the skillful wrist turn and the shaft vibration was examined. And also the skill of the wrist turn for the long drive was experimentally verified by measuring the movement of the wrist and the dynamic deformation of the shaft during the down swing.
