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 trials. Thirty-five markers were placed over the body of the participants. The hit with the longest distance of each participants was selected to be analyzed using Vicon and bodybuilder program. Pelvic angular distance and angular velocity were calculated using vector manipulation and the hitting distance and club velocity analyzed using P3 Pro Swing Golf Simulator.
Results : The relationship between angular distance of pelvic and angular velocity or pelvic rotation was at high level (r=0.95, p<0.01). The relationship between club speed and hitting distance was at high level (r=0.99, p<0.01). The relationship between angular distance of pelvic and club speed and the relationship between pelvic rotation and hitting distance were both at a moderate level (r=0.54, p<0.05; r=0.51, p<0.05, respectively).
Conclusion : Pelvic rotation and angular distance of pelvic correlates with club speed and hitting distance. In order to increase club speed and, thus, hitting distance, golfers need to increase angular distance of pelvic as well as pelvic rotation.
