The relationship of some bio kinematic variables of the throwing phase and their relationship to achievement for javelin throwers under 20 years old

Abstract

The importance of the research appears through its study of the bio kinematic variables using modern analysis devices for the stages of performance and achievement of javelin throw to obtain numbers and statistics that show where the strengths and weaknesses of the performance lie from the beginning of the stage until the achievement. Through these readings and statistics, the trainers have a clear picture to work on correcting and improving the digital achievement. Analyzing the areas of strength and weakness in the motor performance and giving priorities that support the training of this competition is in itself a great work and deserves support, especially when throwing the javelin. This is one of the important problems that most javelin throwers face, which is fluctuation through the motor performance technique for the stages of performance and in the position of the throwing stage because it affects the achievement. The research aims to identify the values ​​of the bio kinematic variables for the throwing stage and the achievement of the javelin throw and to identify the nature of the correlation between the bio kinematic launch variables and the achievement of the javelin throw. The researcher used the descriptive approach using the correlation method, to suit this study, which is the most appropriate for the nature of the problem that the researcher found. The research community was identified as a picture of the javelin throwers of the youth category from the Iraqi clubs. The number of players is (6), while the research sample is (6) players, and the sample represents (100%) of the research community. Exploratory experiments and achievement tests were conducted, and the data were processed statistically. Through this, the researcher reached the following conclusions:

1- The values ​​of bio kinematic variables and their relationship to achievement are of great importance in diagnosing the strength and weakness of technical performance through which performance can be improved and thus achievement among the individuals in the research sample.

2- All bio kinematic variables expressing the throwing stage, if they were at a level that serves performance and achievement, would show a significant correlation among the individuals in the research sample.
