The purpose of this study is to investigate the effects of the shaft length of golf club on swing motion in order to evaluate the ultra-long shaft objectivery and whether it is fitting or not to all kinds of golfers. The subjects were thirteen experienced both sexes golfers. On each swing, the speed of club head at impact was measured. On a few subjects, the motion of body and club were analyzed with DLT method using four cameras, the ground reacting force of each foot was measured by two force plates, and the surface electromyogram of some muscles were detected. The following results were obtained ; (1) The length of club shaft affects to the head speed at impact in all subjects. (2) The differences of wrist angle in swing motion was not appeared. (3) Some dfferences such as moment and weight movement of right foot in down swing were related to shaft length. (4) The integrated amplitude of electromyogram of a few muscles at down swing were reduced in using long shaft.
