العلاقة بين بعض المتغيرات الكنماتيكية لليد الرامية والإنجاز في مرحلة الرمي في رياضة رمي الجلة لفئة الناشئين (13-15)‎ سنة

الملخص EN

This research aims to identifying some of the kinematic variables of the throwing arm, and determining the relationship between these variables and the performance in the release phase.

The researcher followed the descriptive approach to suitability nature of the study.

The sample of the study was 06 players’ males in shot-put for the youth category (13-15 years) of WAK team Khmis Miliana from Ain Defla.

We filmed in one day, and taking the best 04 attempts using a SONY camera with 50 fps.

The motion analysis program KINOVEA was used to find the values of the kinematic variables under study.

The researcher used the SPSS statistical program to process the data.

A significant correlation was found between the linear velocity of the elbow, the linear velocity of the wrist, the release angle of the shot, the release height and the performance of the study sample, and the absence of a correlation between the linear velocity of the shoulder and shoulder angle and performance.
