Abstract
Good hurdling involves running fast and having a good hurdle clearance technique. Running speed can be easily evaluated with a stop-watch. Evaluating good hurdle clearance technique is more complex. It may require a kinematic analysis. The purpose of this biomechanical investigation is to provide a kinematic analysis of the hurdle clearance technique of two junior women hurdlers.
This study could provide local track and field coaches with a procedure to evaluate hurdle clearance technique. It is hoped that such an evaluation could assist in improvement of the hurdling performance.
The hurdle clearance performances of two junior women hurdlers were video recorded. Kinematic performance variables were obtained using the Peak Motus Motion Analysis System. In order to evaluate the standard of the two junior hurdlers and to identify technique efficiency, their hurdling performance variables were analysed and compared with those of elite hurdlers.
It was found that the two junior women hurdlers lacked horizontal takeoff velocity. Their horizontal takeoff velocities (4.78m/s to 5.77m/s) were lower than the elite standard of 8.66m/s. The analysis also indicated that they were not efficient in their hurdle clearance technique. Their hurdle clearance times (0.44s to 0.50s)
were longer than the elite standard of 0.30s. This may be due to their hurdle clearance takeoff angles which were higher (19.6o to 24.1o) than the elite standard of 10.3o. It could also be that they have adopted high vertical takeoff velocities of 2.05m/s to 2.31m/s, which were higher than the elite standard of 1.58m/s.
