BIOLOGICAL MOVEMENT VARIABILITY DURING THE GOLF SWING

##article.abstract##

This study quantified the level and effect of biological movement variability (BCV %) on the golf swing performance of 10 skilled and 10 unskilled golfers. Selected twodimensional kinematic measures were obtained from each player performing ten golf swings with a five iron club. Linear regression analysis was employed to establish relationships between kinematic measures (absolute, CV%, BCV %) and club-head velocity (absolute, BCV %) using SPSS version 12.0. One-way analysis of variance (ANOVA) was used to assess the effect of handicap on all of these measures. Results revealed between-group differences in the mean, CV% and BCV% of several swing kinematic measures. Regression analysis revealed that the strongest predictive model for club-head velocity included handicap and wrist angle at address.
