دراسة تحليلية لمتغير مركز ثقل الجسم وعلاقته بمهارة الرمية الحرة بكرة السلة للاعبي الدوري الممتاز ) Final Four

Abstract

The research objective was to identify the values for the variable of weight center of the body for the successful and unsuccessful free throw skill of the basketball Premier league players ( Final Four) and to analyze the results for the variable of weight center of the body for the successful and unsuccessful free throw skill the research sample. The research included the research methodology and field procedures. The researchers used the correlative descriptive approach to achieve the research objectives after determining the means of data collection and the camera and how to prepare it to conduct the main experiment to give one product aimed at extracting the mechanical variable through the programs of kinetic analysis and the use of a fast digital camera speed of 120 photos/ second . The results were analyzed in a statistical experiment for social sciences (SPSS). The results were discussed on the basis of the real values of the performance, which are the grades. One of the most important conclusions that the researcher has reached was that the emergence of non exaggerate of reducing the center of the body weight to the bottom works to improve performance in the success of free throw. It has been shown that all the players of the research sample were the same level in performance as their numbers in the successful and unsuccessful were at almost one level of performance, which refers to the unsuccessful throw and the rise in the center of the body weight to the successful shot.
