The purpose of the present study was to analyse the variability in clubhead presentation to the ball and the resulting ball impact location on the club face for a range of golfers of different ability. A total of 285 male and female participants hit multiple shots using one of four proprietary drivers. Self-reported handicap was used to quantify a participant's golfing ability. A bespoke motion capture system and user-written algorithms was used to track the clubhead just before and at impact, measuring clubhead speed, clubhead orientation, and impact location. A Doppler radar was used to measure golf ball speed. Generally, golfers of higher skill (lower handicap) generated increased clubhead speed and increased efficiency (ratio of ball speed to clubhead speed). Non-parametric statistical tests showed that low-handicap golfers exhibit significantly lower variability from shot to shot in clubhead speed, efficiency, impact location, attack angle, club path, and face angle compared with high-handicap golfers.
本研究的目的是分析不同能力水平的高尔夫球手在击球时杆头的变化以及球在杆面上的撞击位置。共有 285 名男性和女性参与者使用四种专利球杆中的一种进行了多次击球。自我报告的差点用于量化参与者的高尔夫球能力。一个定制的运动捕捉系统和用户编写的算法用于在击球前和击球时跟踪杆头，测量杆头速度、杆头方向和撞击位置。一个多普勒雷达用于测量高尔夫球速度。一般来说，技术较高的高尔夫球手（较低的差点）产生的杆头速度和效率（球速与杆头速度的比值）更高。非参数统计检验表明，低差点高尔夫球手在杆头速度、效率、撞击位置、攻角、杆路径和杆面角方面的变化明显小于高差点高尔夫球手。
