ゴルフスイングの動作分解に基づくクラブ特性影響評価

抄録

Techniques called ”Fitting”, which considers the individual swing characteristics and suggests a golf club optimal for the player, have attracted attention. In the system developed by the authors so far, we can find optimally designed the golf clubs for the individual swing by swinging nine clubs of different characteristics. In this study, for researching relationship with golf swings and club characteristic, we measured four golfer’s swings by motion capture system. Subjects swung two clubs that differ the shaft kick point, and we composed observance matrix from positional data. We conducted SVD to this observance matrix, and conducted Three-way ANOVA to each club motion. As a result, we can decompose golf swing into simple motion combination, and clarify the timing to be affected by the difference in shaft kick point.
