Analytical Study of Some Biochemical Launch Variables for the Last Throwing Step and the Percentage of Its Contribution to the Achievement of the Javelin Throw of the Applicants

Abstract

The use of devices and their technology in the analysis of performance paths has become an important matter for the stages of throwing performance, and from here the importance of the research appears through its study of biochemical variables using modern analysis devices for the stages. The throwing (achievement) and through these readings and statistics, the coaches' hands have a clear picture of working to correct and improve digital achievement. The problem lies in that the great discrepancy between the Iraqi number and the global and Asian numbers is a problem that must be looked at and carefully considered, especially when the javelin is effective, as it is carried out according to the laws of objects projected at an angle with the horizon and the three laws of Newton and their applications. And that the achievement distance in the Javelin event is undoubtedly subject to a set of biochemical variables, and these can be invested in an organized manner to obtain this required achievement on the one hand, and on the other hand, the launch variables are directly related to the achievement in this event. The aim of the research:1-Knowing the values of the biomechanical variables for the performance and achievement stages of the javelin (for the last throwing step).2-Identify the nature of the correlation between the biochemical variables and javelin achievement.3- Identify the effective contribution percentage of the biochemical starting variables, the performance of the last throwing step and the completion of the javelin throw of the research sample.The researcher relied on the descriptive approach in the method of relational relationships. Completing the six throws, and the sample represents (66.667%) of the research community. The researcher used the means of kinematic analysis for the purpose of extracting the biochemical variables for the last throwing step and 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
