Abstract:

The most important thing that affects the race time is the availability of special physical abilities as well as the external forces affecting the running track of the runner. One of these forces is the centrifugal force because the effectiveness of 400 m / barriers contain two curves, so this strength is a great indication of the race time, where it must be The length and frequency of the steps in the two curves are ideal to a large extent in the face of this force compared to the length and frequency of the steps in the rectum as well as maintaining them between the barriers and the fit of these steps with the barrier step, which must be consistent with the rest of the steps as well as the nature of the upgrading of the left leg to the right foot, so that it secures No decrease in speed or uniform The length of the steps is more than normal, especially when passing through the barriers in the curves, where the focus must be on training the runners physically and skillfully greatly to control the length of the step and its frequency, hence the importance of research through finding comparison aspects between the ratios of some biomechanical indicators between the two curves to enable in the future to develop An appropriate business plan, whether corrective at the skill level or training at the physical level so that the physical and mechanical variables in the curve are in their ideal shape, the purpose of the researchers from the study: - A comparative study between the running of the first and second curves in some biomechanical indicators to pass barriers in the effectiveness of 400 m / barriers. - As for the research tests, they were as follows: / Achievement test for the effectiveness of 400 meters hurdles. - Measuring the average velocity of the first and second curves during the performance of the first test, the second first test, finding the centrifugal force rate at the top of the two curves.
