This study analyzed the influence of the golf club on the swing motion. An experiment was carried out using three 7-irons of different mass and shaft stiffness. Performance was recorded with 10 motion capture cameras, psychological evaluation was evaluated by questionnaire, and the ballistic was measured with a golf ballistic measuring instrument. We analyzed position in the vertical direction of a right wrist marker and considered the flow of the swing motion. We calculated the standard deviation to analyze difference in the swing motion. Comparing the standard deviation, the ballistic measurement results and psychological evaluation, standard deviations could be used as objective evaluation indicators for selecting clubs.
