The purpose of this study was to evaluate possible effects of synchronized metronome training (SMT) on movement dynamics during golf swing performance, as captured by kinematic analysis. A one-group, between-test design was applied on thirteen male golfers (27.5 ± 4.6 years old, 12.7 ± 4.9 golf handicap) who completed twelve sessions of SMT over a four week period. Pre- and post-assessments of golf swings made with three different clubs (4-iron, 7-ironand pitching wedge) were performed using a three-dimensional motion capture system. Club peak velocity at three different swing phases andcross-correlation analysis of time-series signals were made on joint couplings(wrist-elbow-shoulder) of both arms, and between joints and the club, during the full golf swing. There were significantly higher cross-correlations between joint-couplings and concomitant changes of the associated phase-shift differences, as well as reduced phase-shift variability at post-test. No significant effect of SMT was found for the club peak velocities. We suggest that domain-general influences of SMT on the underlying brain-based motorcontrol strategies lead to a more coordinated movement pattern of the golf swing performance, which may explain previous observations of significantly improved golf shot accuracy and decreased variability after SMT.
