دراسة المتغيرات البيوميكانيكية المتحكمة في الأداء الجيد لمهارة رمي الكرة لدى أطفال ما قبل المدرسة (5-6 سنوات)‎

الملخص EN

This study aimed to analyze the kinematic variables that determine the performance of the ball throwing skill in pre-school children aged 5 to 6 years.

A tennis ball throwing test was performed for 30 children from some primary schools in Batna city aged between 5 to 6 years, then the test results were recorded and photographed by a digital camera, and the results analysis showed that many of the kinematic variables are highly related to the measured throwing distance, except for the knee joint angle when throwing the ball, the heel joint angle when throwing the ball and the hand wrist joint angle when throwing the ball.

Among all the kinematic variables, most of the variation in the throwing distance is attributed to the maximum abduction angle of the shoulder joint when launching the ball as well as the speed of the ball when launching the ball, and based on the foregoing, the teachers of motor education as well as coaches should pay special attention to these kinematic variables that contribute to improving the performance of ball-throwing skill in children.
