The knee joint is one of the most frequently injured regions in the game of golf, and the loads experienced by the knee during the golf swing are typically greater than during other activities of daily living. Altering movement patterns is a common strategy that can be used to reduce loading on the knee joint but has received little attention during studies of the golf swing. The primary aim of this study was to examine the effect altering golf stance has on the lead limb peak external knee adduction moment.
Laboratory based, quasi-experimental.
Twenty healthy participants were recruited for a 3-dimensional biomechanical analysis wherein participants hit three golf shots with a driver using the following stance conditions: self-selected, bilateral 0 º foot angle, bilateral 30 º foot angle, wide stance width, and narrow stance width.
Both the 30 º foot angle (0.80 ± 0.51 Nm) and wide stance width (0.89 ± 0.49 Nm) conditions significantly decreased (p < 0.001) the lead limb peak external knee adduction moment compared to the self-selected (1.15 ± 0.58 Nm) golf stance. No significant differences (p = 0.109) in swing speed were found between any of the stance conditions.
The externally rotated foot position and wider stance width decreased the lead limb peak external knee adduction moment without hindering swing speed. Modifying stance could be a viable option for golfers who wish to continue playing the sport at a high level, while reducing potentially detrimental loads at the knee joint.Levels of Evidence: 2b-Individual cohort study.
膝关节是高尔夫运动中最常受伤的部位之一，高尔夫挥杆过程中膝关节承受的负荷通常大于其他日常生活活动。改变运动模式是一种常用策略，可用于减少膝关节的负荷，但在高尔夫挥杆研究中很少受到关注。本研究的主要目的是探讨改变高尔夫站姿对前导肢体膝关节最大外展力矩的影响。
基于实验室的准实验研究。
招募20名健康参与者进行三维生物力学分析，参与者使用以下站姿条件用一号木杆击打三次高尔夫球：自选站姿、双侧脚角度为0°、双侧脚角度为30°、宽站姿宽度和窄站姿宽度。
与自选高尔夫站姿（1.15±0.58 Nm）相比，30°脚角度（0.80±0.51 Nm）和宽站姿宽度（0.89±0.49 Nm）条件下，前导肢体膝关节最大外展力矩均显著降低（p<0.001）。在任何站姿条件之间，未发现挥杆速度有显著差异（p = 0.109）。
外旋脚位和更宽的站姿宽度可降低前导肢体膝关节最大外展力矩，且不影响挥杆速度。对于希望继续高水平参与这项运动的高尔夫球手来说，改变站姿可能是一个可行的选择，同时可减少膝关节潜在的有害负荷。证据等级：2b-个体队列研究。
