(Received August 19, 2011, accepted September 9, 2011) Abstract. The purpose of this study was to compare the selected kinematical parameters of intervarsity and interschool level long jumpers. A total of twelve (six intervarsity and six interschool level) long jumpers were selected for the present study as subjects. To acquire kinematical data two digital Sony DCR SX40E video recording cameras, operating at 1/2000 with a frame rate of 60 frames per second, were used during the respected events. The selected kinematics variables for this study were approach speed, last stride length, velocity of last stride, angle of foot planting, knee angle at take-off and total covered distance. For capturing the movement and motion of the athlete, one camera was placed at a distance of ten meters right side of the run way mounted at a height of five feet used to capture approach run, second camera was used to capture the last stride, foot planting and take-off of the jumpers which was placed perpendicular at a distance of seven meters on the right side of the take-off board the height of the camera was set five feet from the ground. All jumps performed by the selected jumpers during competition were recorded and the best valid jump for each athlete was selected for further analysis. The recorded video footages were downloaded, slashed and edited by using the downloaded version of STHVCD55 software. Digitization, smoothing and analysis were conducted using the Silicon Coach Pro7 motion analysis software. Acquired data were subjected to an independent sample t test for the comparison of the kinematics parameters between intervarsity and interschool male long jumpers. All statistical procedures were conducted using the SPSS (16.0 Version) software. A level of significance was set at 0.05. The results of the study revealed that there was significant difference between intervarsity and interschool level long jumpers in their approach run speed, velocity of last stride and total covered distance where as insignificant differences were observed between intervarsity and interschool level long jumpers in their last stride length, take-off leg knee angle and angle of foot planting. On the basis of the results it is concluded that intervarsity and interschool level long jumpers both exhibited almost same angle of foot planting. Intervarsity athlete yielded good result as their approach run speed velocity of last stride and total covered distance than interschool level jumpers. This might be due to the reason that the training age of the intervarsity jumpers was higher than the interschool level long jumpers. Key words: Kinematics, Long Jumpers, Intervarsity and Inter school. 1. Introduction The long jump has been part of modern Olympic competition since the inception of the Games in 1896. In 1914, Dr. Stewart recommended the “running broad jump” as a standardized track and field event for women. However, it was not until 1928 that women were allowed to compete in the event at the Olympic level. According to biomechanical characteristics, long jump belongs to a group of complex spatial movement and according to motor activity character belongs to a group of natural locomotion without usage of technical accessories. Long jump as athletic discipline consists of four different phases i.e. approach (run- up) phase, phase of bounce off, phase of leap and the last is landing phase. (Hay, 1986). Many jumpers use their maximal speed of approach combined with technique (optimal technique is used to achieve as bigger speed while sprinting as possible and to bounce off as much as possible) hoping to achieve the longest possible distance(Bridgett, Galloway & Linthorne, 2002). The long jumping performance is determined primarily by the athlete’s ability to attain a fast horizontal speed at the end of the approach run (Lees et. al., 1993). While approaching, the jumpers regulate acceleration using their visual regulation in the last three steps (Glizen & Laurent, 1997).To make best use of the run-up speed the athlete must use an appropriate Published by World Academic Press, World Academic Union
