نسبة مساهمة قياسات جسمية و كينماتيكية مختارة بدقة ركلة الجزاء للاعبي كرة القدم

الملخص EN

The study aimed at identifying the results of physical measurements and kinematic variables, and their contribution to the accuracy of the penalty kick in the football game.

the descriptive approach was used in the form of studying relationships.

the sample consisted of (10) from professional clubs players who were chosen in a deliberate way, the researcher used four video with camera speed 60 frames per second then Kinovea program used to get row data and the kinematic parameters examined in this study, and the data were processed through the statistical packages for social sciences (SPSS) program.

arithmetic averages, standard deviations, skew coefficients and percentages, and the simple linear regression analysis were calculated.

the results showed a correlation and a real contribution to the body measurements : leg length, leg and foot length and their height, and kinematic variables : the initial ball launch velocity, its launch angle, and the knee joint angle at the moment of shooting, and the distance of body center gravity from the ball's center gravity, and the length of the last step, researcher recommends that coaches should attend training to show programs to the importance's of anthropometric and kinematics parameters for the penalty kick in football in addition to this it is necessary to appoint a coach to train players to kick the ball with high accuracy.
