The purpose of this paper is to iidentifying the accuracy of the blocking skill from the centers (4, 2) of the volleyball players , identifying the characteristics of the kinetic indicators of volleyball players , identifying the correlation between the accuracy of performing the blocking skill from the centers (4, 2) in volleyball and some kinetic indicators, and finding an equation to accurately predict the performance of the blocking skill from centers (4, 2) in volleyball in terms of some kinetic indicators. The researchers used the descriptive approach using the method of correlational relations due to its suitability to the nature of the problem at hand, including the achievement of the research objectives. The research sample was determined by the intentional method, which represents the volleyball players of the University of Baghdad / College of Physical Education and Sports Sciences for the academic year (2022-2023), who are (8) players who perform the blocking skill. For the purpose of finding out the homogeneity of the research sample in some of the variables related to the research. One of the most important results reached by the researcher is that: There is a clear weakness in the accuracy of the performance of the blocking skill from central (4, 2) of the research sample, there is weakness and no significant correlation between the accuracy of the blocking skill from the centers (4, 2) and the indicators of Streamline and kinetic rhythm ,and there is weakness and no significant correlation between the accuracy of the blocking skill from the centers (4, 2) and the indicators of Streamline and kinetic rhythm. One of the most important recommendations recommended by the researchers is that: need for coaches of Iraqi university teams in the game of volleyball to provide their players with information and knowledge related to the biomechanical aspect of the kinetic performance of all technical skills in the game of volleyball.
