A comparative analytical study on some characteristics of the force-time curve and some biomechanical variables between the average crushing performance of centers 1 and 6 for youth in volleyball

Abstract

The importance of the research lies in obtaining accurate scientific information through biomechanical analysis of the crushing performance of centers 1-6 in order to know the aspects of strength and weakness in the performance of these two centers as well as knowing the levels of force exerted that are commensurate with the nature of each offensive center in order to improve the technical performance of this skill and demonstrate Evaluate their biomechanical characteristics for each center. The aim of the research is to identify the values of some characteristics of the force-time curve and some biomechanical variables for the skill of the rapid crushing beating from the centers 1-6 for youth in volleyball. 6- For young people in volleyball. The third chapter included the research methodology. The researcher used the descriptive approach to solve the research problem. The research sample included specialized school players in Dhi Qar Governorate. The researcher used tools and auxiliary devices as well as statistical methods. As for the fourth chapter, the results were presented and discussed in a scientific discussion, based on scientific sources. The researcher reached some conclusions, including the biomechanical properties of the crushing beating from center 1, which is greater than what is in the crushing beating from center 6.
