Many players can have a huge amount of bewildering information for golf swings by golf magazines and books. However, there is no particular swing for each club. The purpose of this study was to understand characteristic of golf swing using three different clubs: driver, five-iron, and nine-iron. Two right-handed female professional golfers used their own clubs to hit standard golf balls in our laboratory. The swing motions were recorded using a 3D optical motion capturing system with 250Hz frame rate. The results showed that there was a similar timing between the three clubs tested, but kinematics and the club head speed were different depending on the three different clubs used. However, the maximum acceleration of club head appeared at same time, and tendencies of hip rotation until just before impact were similar.
