Comparative of some biomechanical variables for the steps of hurdling (1-4-8) in running (100 m) hurdles for female advanced

Abstract

Biomechanics is one of these sciences that the coach and athlete need simultaneously in training for all sporting events in order to raise the level of motor performance through the use of videography and computers side by side to divide the sporting movement into parts, identify strengths and weaknesses, and attempt to evaluate them. Based on the above, performance cannot be evaluated by the naked eye, which is the method available to most trainers at the present time, which gives a diagnosis that is flawed, in addition to the lack of accurate clarity of performance. Rather, the evaluation must be through modern techniques that follow visual recording of movements to ensure Repeating the observation at any time and without suffering in order to give a clear idea of ​​the performance, address errors, and obtain accurate scientific information and facts accompanying that performance. The 100m hurdles event is one of the events that contain large biomechanical variables such as: (horizontal and vertical forces, all kinds of speed, acceleration, horizontal and vertical displacement, etc.) and physical fitness elements, and the performance of the hurdle step is one of the The most important movement or skill in this event, which requires rapid performance, and that the group of movements in which it is performed are interconnected, such as (rising, movement before the hurdle, movement over the hurdle, movement after the hurdle), and the movements of all these stages need to be observed to discover errors that affect the performance. The technician.
