UPPER BODY ROTATION AND ITS INFLUENCE ON THE GOLF SWING IN ELITE GOLF PLAYERS OF DIFFERENT AGE GROUPS
Abstract
The goal of most players during the golf swing is to achieve maximum clubhead speed at ball contact to reach long ball flight. The aim of this study was to determine the different effect of X-Factor (the difference in axial rotation of the pelvis and upper body) at selected golf swing phases at the pros and elite junior golf players. 3D kinematic analyzer CODA Motion System with 6 active markers was used to sense the position of body segments and the club.
High interindividual stability of performance was found for both groups of golfers at parameter clubhead speed at ball contact. High correlation between Stretch X-Factor and clubhead speed at impact were found at pros and elite junior players.
At pros high correlation and at elite junior players high negative correlation was found between the parameters X-Factor at the top of the backswing and maximum X-Factor and clubhead speed at impact.
