تأثير تدريبات بالأسلوب الهرمي الصاعد في بعض المتغيرات البايوميكانيكية وإنجاز واثبي الطويل تحت 20 سنة

الملخص EN

The problem of the research emerged from several axes, including a weakness in the skill performance during the performance of the jump, and this weakness resulted from not using exercises in a hierarchical manner (ascending), which depend on the gradation in determining the intensity for each jumper separately depends on the level of each jumper taking into account time and distance, while the other axis is the lack of interest of many coaches in the technical aspect of the competition within the training units compared to the physical aspects, and the players not realizing the importance of these exercises as their knowledge of physical exercises, and for the purpose of developing performance and achievement in the long jump competition, the researchers deliberately applied the hierarchical style exercises to the long jumpers randomly from the population of Karbala clubs, where the jumpers were divided into two groups (control and experimental) for each group (5) jumpers, and after conducting the tribal tests and applying the exercises prepared by the researchers for a period of (8) weeks and signing (3) weekly units, and then conducting the post tests, it was concluded that, there is an effect of the hierarchical style exercises in the development of some biomechanical variables and the achievement of long jump under 20 years.
