Abstract:
Purpose: To study the relationships among angular distance, angular velocities of pelvic rotations, club head speed, and hitting distance in university golfers. Methods: Nineteen amateur university male golfers participated in the study. The participants were asked to hit 3 balls with his maximum effort with a minute rest between hitting. Seven markers were placed over the body of the participants. The hit with longest distance of each participants was selected to be analyzed using Vicon and bodybuilder program. Pelvic angular displacement and angular velocity were calculated using vector manipulation, and the hitting distance and club velocity were analyzed using P3 Pro Swing Golf Simulator. Results: The relationship between angular velocity of pelvic and angular velocity of upper trunk rotation was at high level (r=0.83, p<0.01). The relationship between club head speed and hitting distance was at high level (r=0.99, p<0.01). The relationship between angular velocity of pelvic and club speed and the relationship between pelvic rotation and hitting distance were both at moderate level where (r=0.55, p<0.05) and (r=0.53, p<0.05), respectively. Conclusion: Pelvic rotation and angular velocity of pelvic correlates with club speed and hitting distance. In order to increase club speed and, hitting distance, golfers need to increase angular velocity of pelvic as well.
