التحليل الكينماتيكي لمسابقة دفع الجلة بالدوران لمتسابقي النخبة بجمهورية مصر العربية : دراسة حالة

الملخص EN

The main aim of this study is to identify the differences in kinematic variables between an elite Egyptian shot put athlete and world class athletes, 6 attempts were photographed using a high speed camera 120 frames/sec, and the best attempt for was chosen for kinematic analysis .

The results of kinematic analysis were compared with the results of previous studies related to the kinematic analysis of world class athletes.

Through the results of this study, it was concluded that the differences in stage times the shot put event may not related to the differences in the kinematic variables for athletes who achieved a distance of more than 20 m.

Also, the release velocity must be studied according to both height and angle of release.

height of release is a critical variable related to throwing performance, which is related to the whole extension of lower limb joints and the putting arm at the moment of release therefore it must be studied through its relationship to the athlete’s height, which determines the extent of his ability to exploit the morphological characteristics (arm length and body height) in addition to the full extension of all body especially arm joint and lower limb joint during the release moment.
