المستخلص:
تتم خصائص المنحنى البياني لدوال (Dynamic, Static) من خلال تحويل الظواهر الطبيعية في الحركة الرياضية (الضرب الساحق بالكرة الطائرة) من مؤشرات إحصائية إلى شكل منحنيات لبيان الأثر بين متغيرات الدراسة ويشترط في الظواهر الحركية أن تتطور في الزمان لذا يهدف البحث إلىالتعرف على قيم ومميزات خصائص المنحنى البياني وفقاً لمنظومة( 3Dynafoot) للدوال (Dynamic, Static) للمركز التخصصي (1,2) لمهارة الضرب الساحق في الكرة الطائرة وكذلك التعرف على أثر ميكانيكية خصائص المنحنى البيانيفي دالة (Static) للمركز التخصصي ثم التعرف على اثر ميكانيكية خصائص المنحنى البيانيفي دالة(Dynamic) للمركز التخصصي (1,2) لمهارة الضرب الساحق في الكرة الطائرة .
وقد افترض الباحثون وجود أثر ايجابي لخصائص المنحنى البياني لدوال (Dynamic, Static) فيالمركز التخصصي (1,2) لمهارة الضرب الساحق في الكرة الطائرة.
استعمل المنهج الوصفي بالأسلوب المسحي لملاءمته مشكلة البحث وتمثلت عينة البحث بلاعبي المنتخب الوطني العراقي بالكرة الطائرة وفقاً للمركز التخصصي في مهارة الضرب الساحق العالي.
