الملخص EN

The research aims to: -Identifying the values of some mechanical variables related to the butting stage for the accuracy of headshot scoring from jumping and to the right side.

-Recognizing the relationship between the values of some mechanical variables related to the butting stage for the accuracy of scoring in the head and on the right side of the soccer ball.

-Recognizing the differences in the values of some mechanical variables related to the hitting stage for the speed and accuracy of header scoring from jumping and for the right side of soccer.

The researchers used the descriptive approach for its suitability to the nature of the research.

The research community identified the Salah El-Din Governorate club players who participated in the first division football league for the season (2020-2021), and their number is (30) players representing four clubs (Salah El-Din, Al-Alam, Al-Dujail and Al-Sharqat).

The number of the sample members was (30) players, all of whom were chosen, and they constitute a percentage of (100% ) of the original community.

26) players representing a percentage of (86.6% ), which is sufficient for the research requirements.

The researchers used statistical means, including (arithmetic mean, standard deviation, T-test for interconnected samples, skew coefficient, and the computer was used for the purpose of statistical data processing using the (SPSS.25) program).

, and Pearson's correlation coefficient).
