علاقة سرعة الاقتراب في مهارة التهديف بالرأس من القفز في كرة القدم بقيم بعض المتغيرات الكينماتيكية : دراسة ميدانية على أكابر فريق سيدي محمد بن علي الذي ينشط في القسم الجهوي الأول لرابطة و هران

Abstract EN

This research aims at identifying some of the kinematic variables for the skill of scoring by head kicks of football players and the relationship between these variables and the approaching speed.

The researchers followed the descriptive approach, and the sample consisted of 05 players, the senior class from the team of Sidi Mohamed Ben Ali, who is active in the first regional of the Oran League,who were chosen intentionally.

The researchers also used a Sony camera 50f/s, and the kinovea analysis program and they relied on the spss statistical program for statistical processing, The results of this study showed an inverse correlation between the approaching velocity and both the knee angle during pushing and the time of the highest hip height at the moment of hitting the ball, while there was a positive correlation between the approaching speed and both the rise angle and the highest height of the hip joint at the time of hitting the ball and no relationship appeared a correlation between the approaching velocity and both the angle of the trunk, the moment of propulsion and the moment of striking the ball.

There fore, the speed of approach has a significant role in the performance of this skill, as it helps the player to upgrade well, and the researcher recommends improving this speed during training because of its positive role in the values of some kinematic variables in the performance of the head scoring skill.
