THE EFFECTS OF GOLF SHAFT AND CLUBHEAD ON THE VELOCITY OF CLUB-HEAD AND BALL

##article.abstract##

The purpose of this study was to investigate 1) the influence of the bending stiffness of the golf shaft on the velocity of the club-head and the ball, and 2) the influence of different club-heads on the velocity of the club-head and the ball. Four different drivers made up of two different shaft stiffness (R-stiff, L-flexible) and club head (Titanium, Graphite) were used in the experiments. The results showed that the shaft stiffness L resulted in slower before-impact club head velocity than the shaft stiffness R, whereas the shaft stiffness L resulted in higher maximum ball velocity than shaft stiffness R. But the result in the statistics showed no significant club-head material effect on either clubhead velocity or the ball velocity. And there was no significant shaft stiffness effect on either club-head velocity or the ball velocity.
