“…For this reason, some previous studies have used clubhead speed as an indicator of optimised performance (e.g. Hume et al, 2005;Pickering & Vickers, 1999;White, 2006). Furthermore, it has been demonstrated that better golfers are indeed able to generate higher clubhead speeds (Bradshaw et al, 2009;Fradkin, Sherman, & Finch, 2004;Hocknell, 2002).…”

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.

“…A recurrent simplification in the golf swing literature has been the assumption that the downswing can be represented as a movement occurring in a single constant plane [3,[6][7][8][9][10][11][12][13][14][15][16]. However, there is research which suggests the downswing is not planar.…”

Previously, forward dynamic models of the golf swing have been planar, two-dimensional (2D) representations. Research on live golfers has consistently demonstrated that the downswing is not planar. This paper introduces and evaluates the validity of a 3D six-segment forward dynamics model of a golfer. The model incorporates a flexible club shaft and a variable swing plane. A genetic algorithm was developed to optimise the coordination of the model's mathematically represented muscles (torque generators) in order to maximise clubhead speed at impact. The kinematic and kinetic results confirmed previous findings on the proximal to distal sequencing of joints and the muscles powering those joints. The validity of the mathematical model was supported through comparisons of the model's swing kinematics and kinetics with those of a live golfer.

“…Since, others have concentrated on golf swing physics, ranging from planar rigid-link models [2][3][4][5][6][7][8] to three-dimensional kinematic analysis [9][10][11][12][13][14][15]. The objective of most studies is to study the effect of body segment rotation, or the applied torques generating segment rotation, on the performance of the golf swing, which was primarily characterised by club head velocity at impact.…”

Three-dimensional kinematic analysis of the golf swing using instantaneous screw axis theory, part 1: methodology and verification

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique, instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study, the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular velocity relative to that segment's ISA and verify that ISA theory is a valid tool to analyse segment rotation during the golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore, ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that motion about the ISA is representative of joint motion.
