摘要：This study was structured to detect whether the joints velocity during approach run has an impact on the jump height (performance). For the purpose of this study twelve male high jumpers who perform Fosbury-flop technique were recruited as the subjects. To acquire kinematical data during the competition the camcorder mounted at a height of 1.5 meters was placed at 10 meters away, perpendicular to the approach area. All subjects were performed three jumps, all the jump performances were recorded and downloaded in the personal computer and only successful jump performance of each subject was selected for further analysis. The digitization of the obtained data was done with the help of Silicon Coach Pro7 software. The kinematical variables for the study were ankle, knee, hip, shoulder and elbow joints’ velocity. All statistical procedureswere conducted using the SPSS 16.0. The correlation-coefficient was used to establish a relationship between biomechanical variables and jump height (performance) of high jumpers. The results of the study revealed that there was significant relationship exist between ankle, hip, shoulder and elbow joint velocity with the jump height (performance) and insignificant relationship existed between knee joint velocity and jump height (performance). On the basis of the results it is concluded that during the approach run the velocity of the different joints affect the jump height (performance of the high jumpers).
