نسبة مساهمة التغير الزاوي لبعض مفاصل الذراعين والرجلين في مجال طيران كرة السلة في التصويبة الثلاثية

Abstract

The purpose of the study is to identify the angular change of the upper & lower joints during the triple throw in basketball games. The research proposed that the angular change of the upper & lower joints are major centri but ore to the value of the variables of speed & angular course of the ball during triple throw. A sample of Qatar National Basketball Youth Team who participated in Asia 2000 has been chosen to analyze the Triple Throw. A number of photos were analyzed by utilizing special software that precisely measures mechanic changes of the joints of the upper and lower limbs of the body as far as tirnei distance i angular displacement and angular speed are concerned. The extent of joint contribution in the speed and the angle at which the ball is shot has also been assessed. The study came to the conclusion that the angular speed of the joints of knees and elbows are major contributors in the values of the variables of speed and angular course of the ball heading to the basket.
