Abstract: The purpose of the study was to investigate the relationship of selected kinematic variable with the performance on sitting start of bunch start. The start and acceleration from the blocks directly affect results in the sprint events. In this study, the major kinematic parameters of these phases of the race were analyzed in the terms of kinematic variable like Angle at various joints, Centre of gravity, Height of centre of gravity from ground, location of centre of gravity within the base of support, Base of support. The subject of the study was the five national level male sprinters, who was participated in All India University Championships. The study showed the following to be the key factors for performance in the two phases: of on your mark and set position, the participants for the study were five male national level player athletics, amity university, Noida the age of the subject was 19-24 years. Still photography was used to take the different phase of both the start “ON YOUR MARK” and “SET” these two phases were taken on both the start bunch start and elongated start. A cannon D50 was used (DSLR) were used in still photography on sagittal plane of the participant each participant were given two trails of bunch start (phase “on your mark and “set”) and elongated start (phase “on your mark and “set”) were taken and the best trail was used for the analysis. From the photographic sequence, the sticfigure were prepared by using joint point method, and the various angular kinematic variables were obtained at the moment stance and take off. Segmentation method was employed in order to assess the center of gravity of the body during “on your mark” and “set” position the data was analyzed by using Pearson’s product moment correlation to ascertain the relationship of the selected kinematic variables with the performance of standing long jump of the subjects.
