As golf increases in popularity, more golfers seek the proper mechanics necessary for the perfect golf swing. Surprisingly little scientific work has been published on the contribution of the hip and knee muscles during the golf swing even though most professionals have recognized their vital contribution. Recent studies have described the electromyographic (EMG) muscle activity of the shoulder, back, and trunk during the golf swing. The purpose of this study was to describe the electrical muscle activity in seven hip and knee muscles of both the left (lead) and right (trail) leg in competitive golfers while performing the golf swing. Sixteen golfers were studied with indwelling electrodes and high-speed cinematography. The EMG was synchronized with the film to discern five phases of the golf swing. Means, SDs, and t-tests were done. The results revealed that the trail hip extensors and abductors in conjunction with the lead adductor magus initiated pelvic rotation during forward swing. The lead hamstrings maintained a flexed knee and provided a stable base on which pelvic rotation took place. The peak EMG muscle activity recorded in the hips and knees occurred in an earlier phase than that measured previously in the trunk and shoulder. This confirmed the sequential firing pattern of the hip and knee muscles that takes place during the competitive golf swing. Information gained from this study can be used by players and coaches to optimize performance and to minimize injury.
随着高尔夫运动越来越受欢迎，越来越多的高尔夫球手寻求完美挥杆所需的正确力学原理。尽管大多数专业人士已经认识到髋部和膝部肌肉在高尔夫挥杆过程中的重要作用，但令人惊讶的是，关于它们贡献的科学研究却很少发表。最近的研究描述了高尔夫挥杆过程中肩部、背部和躯干的肌电图（EMG）肌肉活动。本研究的目的是描述竞技高尔夫球手在进行高尔夫挥杆时，左右腿七块髋部和膝部肌肉的电肌肉活动。对16名高尔夫球手进行了留置电极和高速摄影研究。将肌电图与影片同步，以识别高尔夫挥杆的五个阶段。进行了均值、标准差和t检验。结果显示，在后摆过程中，后侧髋部伸肌和外展肌与前侧大收肌共同启动骨盆旋转。前侧腘绳肌保持膝关节屈曲，并为骨盆旋转提供了一个稳定的基础。髋部和膝部记录到的肌电图肌肉活动峰值出现在比之前在躯干和肩部测量的更早阶段。这证实了竞技高尔夫挥杆过程中髋部和膝部肌肉的顺序放电模式。球员和教练可以利用本研究获得的信息来优化表现并尽量减少受伤。
