دراسة المتغيرات البيوميكانيكية المتحكمة في الأداء الجيد لمهارة الوثب العريض من الثبات لدى أطفال ما قبل المدرسة (5-6 سنوات)‎

Abstract EN

This study aimed to analyze the kinematic variables that determine the performance of the long jump in preschool children aged 5 to 6 years.

A standing long jump test was carried out for 30 children from some primary schools in Batna city aged 5 to 6 years, Testing by a digital camera, the analysis of the results showed that many kinematic variables are highly correlated with the measured jumping distance, except for the knee joint angle at the maximum shoulder extension, the ankle joint angle at the shoulder maximum extension angle and the shoulder joint angle at the maximum knee flexion angle.

The progressive multiple regression analysis of the results also showed that of all kinematic variables, most of the variation in jumping distance is attributed to take-off distance and take-off speed.

Therefore, motor education teachers and trainers should pay particular attention to these kinematic variables that improves the performance of the standing long jump in preschool children.
