اثر استخدام النظام النازل و الهرمي بتدريبات الأثقال في بعض أوجه القوة العضلية و بعض المهارات الأساسية بالكرة الطائرة

Abstract EN

The research aims at revealing the following : 1) effect of using the declivity and pyramid weights training systems on some aspects of muscular strength and basic skills in the volleyball Which systems are more effective on some aspects of muscular strength and basic skills in the volleyballs.

To verify the research objectives ; the researchers set the following hypotheses: 1) There are significant differences between pre and post tests of the declivity and pyramid systems in some aspects of muscular strength and basic skills in the volleyball's players.

2) There are significant differences between post tests of the declivity and pyramid systems in some aspects of basic skills in volleyball's players.

The researcher has applied the experimental methodology for its convenience with the research nature.

The experiment was implemented on a population of players from Neinavah Young Team for volleyball reached (18) players aged (16-19) chosen intentionally and were divided into two experimental groups by lot.

Group one applied the delivity system, whereas the second applied the pyramid system.

(6) players were excluded for the explorative experiments.

Equivalence and homogeneity were achieved between both groups of the research.

Pre-tests of the muscular strength aspects and basic skills were carried out as well as the training program.

Execution of the training program has lasted (8) weeks with a load movement undulation (3:1) in the amount of (3) training units per week.

Then posttests of muscular strength aspects and basic skills were performed.

The researchers employed the following statistical tools and attained the following conclusions: -The two systems were effected clearly in some aspects of muscular strength.

-The two systems were clearly effect on some basic skills in the volleyball.

Based on the conclusions attained ; the researchers recommended the following : -The two training systems can be applied in developing muscular strength aspects and basic skills in volleyball.

-Confirm the use of the pyramid training system which has showed an evident superiority over the declivity system in developing muscular strength aspects and basic skills in volleyball.
