The Percentage of the Contribution of some Biomechanical Variables to the Final Throwing Step and the Achievement of the Javelin Throw to the Applicants

The rapid development that occurred in athletics activities, especially the javelin throwing event in the world, was the result of using the latest technology and all research tools to study the parts of the movement and discover its errors and try to overcome them by finding the correct motor path through correct kinematic guidance to ensure the requirements for success in performing the technical stages of the effectiveness, and from Here the importance of the research appears through its study of biomechanical variables using modern analysis devices for the stages of performance and completion of the javelin throw to obtain figures and statistics that show where the strengths and weaknesses of performance (achievement) lie, and through these statistics it becomes in the hands of the trainers a clear picture of work to correct and improve the digital achievement. The researcher should address the truth of the correlation relationships between the most important biomechanical variables that characterize the individual of the research sample and find the true correlation coefficient for these variables with the achievement achieved. The best performance of the archer to achieve achievement a For the best. The aim of the research:1- Identify the nature of the correlation between the biomechanical launch variables and javelin achievement.2- Identifying the contribution percentage to the biomechanical launch variables in the performance of the last throwing step and the completion of the javelin throw.The researcher relied on the descriptive approach in the method of relational relationships. The researcher chose a community by the deliberate method from the javelin players, the applicant category of Iraqi clubs, whose number is (9) players. As for the research sample, their number reached (6) players and (3) players were excluded because they were unable to Completing the six throws, and the researcher used the means of kinetic analysis for the purpose of extracting the biomechanical variables for the last throwing step. The results were processed by appropriate statistical means. The researcher drew the following conclusions:- The contribution rate to the angle variables did not indicate the effectiveness of these variables in achievement.The researcher recommends the following:- The use of periodic kinematic analysis and interpretation of the results of the analysis in line with the development of ideal performance
