علاقة بعض المتغيرات البيوميكانيكية لمراحل الارتكاز في الوثبة الثلاثية بالانجاز الرقمي

Abstract

The kinetic analysis used to determine sports performance and movements and the skill level of the players accurately, and from which to extract the values of biomechanical variables and compare it with the model to see the strengths and weaknesses of player performance and contribute to the performance optimization for the best biomechanical variables, since the Objective of our research to study the relationship between the biomechanical variables in the triple jump stages the digital implementation level.
We used the descriptive approach based on the analysis method using the kinetic cinematography, where the research sample consisted of national Players in the triple jump were chosen intentionally.
After analyzing the results, and we discussed the following:
-existence of a positive correlation between the level of achievement and every digital angle of the leg, the angle of the hip, the angle of the trunk in a collision during the cloche and push for the jump.
- Existence of a negative correlation between the angle of the knee and the level of digital achievement by step cloche in the collision.
