دراسة بعض المتغيرات البايوميكانيكية والقدرات البدنية وعلاقتها بانجاز100م حواجز للنساء

Abstract

A study of some biomechanical variables and physical abilities and their relationship on the 100 m barriersThe research contains the effectiveness of the 100 meter hurdles and the most important physical abilities and biomechanical variables, and their impact on the level of accomplishment. The research problem was the evident weaknesses in the achievement level of the fourth stage students in this event as a result of weak capacity, and physical variables, and the biomechanical changes. The research aims to study the seriousness of the barriers and the speed of the performance, endurance, and strength and their relation to accomplishment. The research hypothesis was to find a relationship between the seriousness of the barriers and the speed. An analysis of the dynamic variables and physical tests was made on a sample of students from the fourth stage, and then a statistical processing of the data was done.Important conclusion 1. Through the above noted a link between the physical abilities, and the biomechanical changes, and their relation with accomplishment. 2. The weakness level of the physical abilities effects negatively on the biomechanical changes, and so it effects negatively on the accomplishment.Important recommendation
