THE EFFECT OF STRENGTH EXERCISES CHARACTERIZED BY SPEED IN DEVELOPING THE VALUES OF SOME BIOMECHANICAL VARIABLES TO PERFORM THE OFFENSIVE BLOCKING SKILL FROM POSITION (2) WITH THE VOLLEYBALL PLAYER FOR THE SPECIALIST (POSITION

Abstract

The importance of the research lies in the development of the values of some biomechanical variables by using the speed-distinguishing strength exercises of the offensive repelling skill from Center 2; Because this skill is one of the important skills that need this characteristic to carry out the motor duty; As these exercises increase the efficiency of the muscles to exert greater force to reach maximum strength and maximum speed, the player ensures that the parts of the skill are linked with the least possible decrease in speed and linear momentum as a result of the increase in internal strength. As for the research problem, it was manifested through the researcher's observation of the apparent weakness in the performance of the offensive blocking skill of the specialized player from position 2. The study aimed to identify the differences between the pre and post tests of the experimental research group in the values of some biomechanical variables for the performance of the offensive repelling skill. The research sample consisted of the players of the Specialized School in the district of Souq Al-Shuyoukh in Dhi Qar Governorate, who numbered six players. As for the conclusions, the most important of them is the emergence of a clear development in the level of technical performance of the skill of the offensive blocking wall from center 2 as a result of the development of the values of the biomechanical variables.
