التحليل البيوميكانيكي لبعض متغيرات الإنجاز لدى عدائي سباق 100 م

الملخص EN

The research aims to determining the values of some variables biomechanics under study (Thelength of the firstof four steps of race, the speed of the runner in the first, second and third sessions of 20 m stages, steps frequency of the first 20 m and the length rate of this steps, and the overall outcome of the race) and get to know the relationship between some variables kinematics above of the 100m sprint runners.

In order to achieve the objectives of the research we used the descriptive approach, and we did tests on fours spring runners from Star Club Athletics HassiBahbah, and for gathering information about the search variables, we used a set of tools of two cameras and a computer the following programs (Kinovea kinesthetic analysis version 0.8.15,year 2014 AfterEffect , PHOTOSHOP).

Based on statistical analysis, a matrix of moral links has been reached between the variables under study.

On the basis of the results researchers recommends to focus on the first steps of the race when training and analys the performance due to its link with different steps of the race and frequency and lengh of the step for the first 20 meters.
