تحليل بعض المتغيرات البايوكينماتيكية لحركة الضربة بوجه القدم الداخلي للكرات الثابتة و علاقتها بدقة التهديف البعيد بكرة القدم

Abstract EN

The research has been held on a sample of three players of football team of Mosul sport club of first degree.

The present research aime at: 1.

Knowing of changeable biokinmaticia feactures for the skill of ball strike (hit) by the internal (inside) foot frant football from the fixed point and outside of penalty area and the three directions of the platform (right, middle and left) .

2.

The knowledge of the relationship between the values of some biokinmaticia changes for the front foot strike (hit) from inside of fixing and for the far scoring accuracy in football from the three direction.

The research supposed that there was no fixmd significant relationship among the values some of the biokinmaticia changes and the scoring accuracy.

The researchers used a video camera with a speed of 25 photographs per second and placed on a height of 1.10 M of the ground and on a 6.5 M distance from the right side of the player and the distance to the goal was 20 M for the three directions, namely right, middle and left.

mean while, a drawing measure of 100 cm length was used after the complete warming up without the intervening of any individual, then the player according to the game circumstances during the process of scoring from the fixing point.

Every player was given six tries from the right side then the middle and left and a mark was given for every player according to its falling in the goal whose marks (dgress) were identified on the condition that the final mark for the combination of the three i.

e.

30 marks for each direction.

The research used the scientific notes, technology, measuring, analysis and the information as means of collection data for the purpose of getting values for some biokinmaticia parameters values whereas every player performs (achieves) six trials for which 5 marks as a maximum and zero as a minimum and the best try was analyzed.

An acquaintance experiment has been held followed by a basic experiment held on the research sample and after that the results were treated statistically by the use of the mathematical mean the deviation criterion and the simple correlation and the researcher have achieved the following conclusions: 1.

All the correlative significant values were negative.

2.

In the stage of collision we obtained a significant correlative values between the angle of the knee and the scoring accuracy from the left.

3.

In the stage of absorption we obtained a significant negative correlation between the knee angle and the scoring accuracy from the right side and the angular velocity of the body and the scoring accuracy from the middle.

4.

At the stage of kiking, we obtained a significant negative correlation relationship between the angle of the hip and the height of the mass weight center of the body and the scoring accuracy from the middle and also the angular velocity and the scoring accuracy from the right side.
