When the golf swing is involving all body segments and is thus considered as one of the most complex of sports motions. The aim of this study was to determine the selected kinematic parameters of movement of pelvic and segments of the upper body (shoulder rotation, hip rotation, X-Factor, stretch X-Factor) that affect the club head speed at ball contact in elite golfers. To build the upper body segment model were used spots and their position during the measurement was scanned by 3D kinematic analyzer CODA Motion System. To determine the interindividual stability of performance the coefficient of variation was used and for statistical analysis of the relationship between kinematic and temporal parameters and the club head speed at ball contact the Pearson's correlation coefficient was used. We found a high interindividual stability in maximized shoulders rotation and club head speed at ball contact parameters. When analyzing relationship between the club head speed at ball contact and the observed kinematic parameters of the movement of the upper body only a high relationship with the stretch X-factor parameter was found.
