Abstract

يستخدم المختصون كافة الوسائل التي تساعدهم الى الوصول لتحقيق الأهداف ، سواء لكشف الاخطاء وتصحيحها ، او لتحديد نقاط الضعف ومعالجتها ، او اضافة وسائل ومعينات اكثر فاعلية لتطوير الاداء . وتعد وسائل التحليل الحركي التي يعتمدها علم الميكانيكا الحيوية احد اهم وأنجع الوسائل التي تساعد على كشف الاخطاء التي ترافق الاداء من خلال تحديد قيم المتغيرات التي تمثل مواصفات الاداء ، وتركز هذه الدراسة على تحديد قيم متغيرات سرعة الحوض وسرعة القوس المشدود ، وسرعة انطلاق الرمح ودراسة العلاقة بينها ، وقد طبقت الدراسة على 5 رماة رمح سوريين من اعضاء المنتخب الوطني والذين شاركوا في بطولات عربية وأسيوية . وقد توصلت الدراسة الى وجود علاقة ارتباط معنوية بين سرعة الحوض وسرعة الانطلاق ،وعدم وجود علاقة ارتباط معنوية بين سرعة القوس المشدود وسرعة الانطلاق ،و بين سرعة الحوض وسرعة القوس المشدود .فضلا عن انخفاض مستوى سرعة انطلاق الرمح وتدنى هذا المستوى عن المستوى الذي حققه الابطال العالمين . وان هناك ضعف في الاستخدام الجيد للنقل الحركي والاستفادة من القوى الناتجة من الاقتراب . Specialists use many methods to achieve their aimes .These methods help to detect and correct errors ,in addition to identifying and addressing the weaknesses ,or to add more effective tools and aids in order to develop the performance . The kinetic analysis methods adopted by the biomechanics are considered one of the best and most effective methods which help detecting the errors associated with the performance through evaluating the variables representing the performance specifications. This study focuses on the determining the values of the pelvis speed , and stretched bow speed as variables and the speed of Javelin launching and studying the relation between them. This study applied on five Syrian Javelin throwers from the national team who participated in Arab and Asian championships. The study concluded that there was a significant correlation between the speed of pelvis and the launching speed , and there was no significant correlation between the speed of stretched bow and the launching speed neither between the speed of pelvis and the speed of stretched bow. In additionto the low level of the javelin speed lower than world champion's level .There is a weakness in the using of the kinetic transport and in taking advantage from the forces resulting from approach .
