Training of the instantaneous ability of the arms and legs and their effect on some biomechanical variables of the throwing position and the level of achievement of javelin throwing under the age of 20 years

Abstract

The results of javelin throwing in the world championships witnessed a remarkable development in the level of digital achievement for young people. This development is linked to the development of the players’ physical abilities. There were many different ways and means of training in order to compete to get the farthest possible distance in this event. Therefore, the importance of research came in the number of instantaneous ability exercises for the arms and legs And knowing their impact on some biomechanical variables and the achievement of javelin throwing for the youth category, the researcher prepared these exercises and applied them to (8) javelin throwers belonging to the Iraqi Athletics Federation who are under (20) years old. For the driving leg, the instantaneous thrust of the leading leg, the instantaneous thrust of the driving leg, the force exerted to the throwing arm, the starting speed, the angle of performance and the distance of achievement), and the research problem was that the exercises used did not take into account many variables and what the athlete needs from the training of instantaneous ability for the purpose of Achieving the technical performance correctly, which is directly reflected on the achievement, and the results showed a remarkable development in the values ​​of the work Biomechanical changes measured and accomplished.
