Trunk Rotation and Weight Transfer Patterns between Skilled and Low Skilled Golfers

The purpose of this study was to examine trunk rotational patterns and weight transfer patterns that may differentiate swing skill level in golfers. Thirteen skilled golfers (mean handicap = 0.8 ± 2.6) and seventeen low skilled golfers (mean handicap = 30.8 ± 5.5) participated in this study. Kinematic and kinetic data were obtained through high-speed 3-D videography and force plates while the participant performed a full shot golf swing with a driver. Data at six temporal events during the swing were selected for the analysis. The results indicated that significant differences existed between the groups in the multiple events, as the skilled golfers showed the following motion patterns when compared to the low skilled golfers; 1) An earlier trunk horizontal rotation with a rapid weight transfer to the trail foot during the backswing; 2) An earlier pelvic horizontal rotation accompanied with an earlier weight transfer to the lead foot during the downswing motion; and 3) Less upper trunk horizontal rotation and more posterior pelvic rotation at the follow through. Collectively, these finding may be useful for instruction of golfers to improve their swing mechanics on a full shot golf swing. Key pointsDifferent trunk rotation and weight transfer patterns were found between skilled and low skilled golfers.Earlier trunk rotation accompanied with earlier weight transfer to the trail foot during the back swing was evident in the skilled golfers.Earlier pelvic horizontal rotation with a rapid weight transfer to the lead foot during the downswing was evident in the skilled golfers.
