Kinematic Factors Related to Forward and Vertical Release Velocity in Male Javelin Throwers

The purpose of this study was to determine the kinematic factors related forward and vertical release velocities in male javelin throwers. movements 115 throwers who participated real competitions were videotaped by two cameras, coordinate values obtained using three-dimensional motion analysis technique. time-series changes data calculated, relationship with velocity directions confirmed calculating partial correlation coefficient. center gravity whole body from right foot contact left commonly higher for velocities. angle trunk backward lean at smaller (more upright) larger velocity. At release, had a angular shoulder abduction horizontal adduction, horizonal adduction. These results indicates that throw are greatly different.
