The relationship of the loss of elasticity to some of the anatomical changes of the lower end of the obstacle racers

The aim of this study is to identify the relationship of loss of elasticity to some of the anatomical changes of the lower side of the obstacle racers. The sample of the research was chosen in a deliberate manner by the participants of the barriers and the registrars in the Egyptian Federation (8) players of the contestants of the barriers were conducted anatomical measurements of the lower limb bones and measurements of loss of flexibility in the sample research. The results and recommendations revealed that there are clear differences in the research sample in the anatomical variables of the lower limb and morphological and that there is a relationship between the measurements of the loss of flexibility and the anatomical changes of the lower side. It was also revealed that the exercises increased the strength and stiffness of the bones and improved the morphological condition of the players. To train flexibility and others needs to exercise strength to achieve balance and completion of the skill and achieve the highest level of digital and the emergence of positive results may help trainers in the direction of training and specialists , injuries and rehabilitation in the design of rehabilitation programs that Tnas With injury prevention barriers have runners .
