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.
本研究旨在探讨可能区分高尔夫挥杆技能水平的躯干旋转模式和重心转移模式。13 名技术娴熟的高尔夫球手（平均差点=0.8±2.6）和 17 名技术较差的高尔夫球手（平均差点=30.8±5.5）参加了这项研究。运动学和动力学数据是通过高速 3D 录像和测力板获得的，参与者用球杆完成全挥杆高尔夫挥杆。在挥杆的六个时间事件中选择数据进行分析。结果表明，两组在多个事件中存在显著差异，与技术较差的高尔夫球手相比，技术娴熟的高尔夫球手表现出以下运动模式；1）在挥杆过程中，躯干水平旋转较早，同时重心迅速转移到跟随脚；2）在下降阶段，骨盆水平旋转较早，同时重心较早转移到前脚；3）在结束阶段，躯干水平旋转较少，骨盆向后旋转较多。总之，这些发现可能有助于指导高尔夫球手改善全挥杆高尔夫挥杆的挥杆力学。关键点熟练和技术较差的高尔夫球手之间存在不同的躯干旋转和重心转移模式。在挥杆过程中，较早的躯干旋转伴随着重心较早地转移到跟随脚，这在技术娴熟的高尔夫球手中表现明显。在下降阶段，较早的骨盆水平旋转伴随着重心迅速转移到前脚，这在技术娴熟的高尔夫球手中表现明显。
