An Analytical Study of the Mechanics of Motor Performance According to Body Angles for Some Biokinematic Variables and Their Relationship to Achievement in Youth Javelin Throwers

Abstract

A study of the mechanics of motor performance according to body angles for biokinematic variables using modern analytical devices for the stages of javelin throw performance and achievement is conducted to obtain figures and statistics that demonstrate the strengths and weaknesses of performance from the beginning of the stage until achievement. Through these readings and statistics, coaches have a clear picture to work on correcting and improving numerical achievement. The research aims to identify the values ​​of the bio kinematic variables for the stages of javelin throw performance and achievement, and to identify the nature of the correlation between the bio kinematic launch variables and javelin throw achievement. The researcher used the descriptive approach using correlational relations. To suit this study, and as it is most appropriate to the nature of the problem, the research community was defined as youth javelin throwers from Iraqi clubs for the third round of the Iraqi Clubs and Institutions Athletics Championship for the sports season (2022-2023), numbering (9) players. The research sample numbered (6) players, representing (66.67%) of the research community. Exploratory experiments and achievement tests were conducted, and the data were statistically processed. The researcher reached the following conclusions:

1- The mechanics of motor performance according to body angles through the studied variables indicate the effectiveness of these variables in achievement.
