تأثير تمرينات توافقية في تطوير تزامن حركة الذراع الرامية مع ارتكاز القدم و بعض المتغيرات الكينماتيكية لمرحلة الرمي و الإنجاز للاعبي الرمح

الملخص EN

The introduction and significance of the research generally revealed the effectiveness of shooting spear in terms of technical stages and the need to be interconnected by high compatibility and flow .In particular, the researcher pointed to the importance of shooting spear stage and its kinetic changes, and the importance of the movement of the leg anchor should be in parallel with the movement of the arm through applying exercises for that purpose.

The research problem lies in the need of promoting the level of compatibility with the stage of shooting through synchronizing the leg movement with the shooting arm movement .

The research objective is to identify the effect of consensual exercises in synchronizing the movement of the arm with the leg anchor and some kinetic variables of the shooting stage .The research hypothesis was that there was a positive effect for those consensual exercises in developing the research variables .The researcher used the experimental method to solve this problem by designing the two control and experimental groups.

The research sample was young players of Maysan province of shooting spear .The research tools were the test and measurement.

The two groups were tested by pre and post tests.

The exercise was carried out for eight weeks with two training sessions per week on the experimental group.

After the main experiment, the two groups were tested by post test at the same conditions of pre-test.

The data were collected in special forms for processing statistically through using statistical laws.

The results were showed, analyzed and discussed scientifically.

The results were all significant .

Based on the results ,the researcher concluded that the kinetic synchronization between shooting arm and anchor leg has a positive effect on the achievement of spear shooting.

In light of this, the researcher recommended it is important to pay attention to these kinetic variables and the kinetic synchronous state of the spear shooter.
