A comparative study of kinematics of block start position in between Asafa Powell and sprinters of national sports university


Author(s): Raushan Kumar Scholar and Harish Kumar Tiwari

Abstract:
This study investigated the set position of Asafa Powell (9.77 second) and sprinter of National Sports University, Manipur to determine the Set Position of both and enhance the performance of university level players by modifying the Set position according to an Olympic level player i.e., Asafa Powell.
This is a case study to determine the kinematics of start on starting block in between 100 m sprinter Asafa Powell and Sprinter of National Sports University, Manipur India. The start position of Sprinter was recorded by a high-resolution Camera and Picture of Asafa Powell was taken from a non-copyright website. Personal best timing of the sprinter is 11.95 Second, timing of Asafa Powell in respective race is 9.72 Seconds. a high-resolution digital camera (Nikon DSLR, India Asia, Pacific), sampling at 300 Hz with a pixel resolution of 6000 x 4000, were strategically placed along the track to capture data from the university level player, and Picture of both the players are analyzed with the help of ‘kinovea’ version 0.9.5 software, along with the Set-Position picture of Asafa Powell.
We found that the hip joint angle of Asafa Powell is greater than university player (79.1< 93.5) this may be due to the placing of starting block closer to starting line. In order to increase the angle of hip joint, the starting block needs to be placed slightly back. Elbow flexion angle is greater than of Asafa Powell (166.9 >147.8). The flex elbow helps athletes to lift up their body with greater force and also helps to lift quickly that may decrease the time taken by athletes during starts and leads for faster start. Right ankle joints having also very much difference (102.7>88.9). In Performance analysis, it has been recommended that the lower the flexion angle of ankle helps athletes to bring their leg forward quickly, greater angle may laps 0.03-0.05 milli second extra time during takeoff from starting block. Right knee angle (118.3<136.7) also needs to be more extended for leisure time during takeoff. Left legs ankle and knee angle are almost same there are only two to three degrees of difference. For improving Sprint Performance, the university sprinter needs to modify the set position as per recommendation.
