Abstract
The aim of the research is identifying the accuracy values of skilful movement of the Pool Long Serve ,and also some kinematical variables for the serve, and the relationship between some kinematics variables and the accurate movement / The researcher followed a descriptive methodology for its suitability to the nature of the research, the sample of the research is consists of four players -,the camera is on (6) meter distant to player right side and its (1.2) meters high above surface of the court with speed of (25) frame per second .The data are handled statistically by using mean ,standard deviation ,and correlation / The researcher concluded that there was significant correlation between (the vertical distance for primary stage ,vertical speed for primary stage , The velocity of the hand and racket for the main stage ,linear speed to middle of racket for the main stage ,and the corner of the body to get the racket towards the back of the body for the main stage, time for final stage) and accuracy of the long high serve . and there is negative correlation between (the vertical distance for the center of gravity for the correlation stage , the vertical speed for the final stage) and accuracy of the long high serve . The researcher recommended the following :T0 insure getting the hand back and up in primary stage so as to increase the vertical distance and vertical speed . t0 insure getting the drank back and up so that the racket be towards the back to increase distance movement . to insure the speed up and down movement with the extending of arm to make the player gain on the speed of distance movement of the head of the racket in addition to high speed for their high effect on performance accuracy . after the stage of hit the badminton we assure the corset following of arm till the stopping of the racket by the increasing of time because of their coorelation with the performance accuracy in lessening of horizontal distance and horizontal speed for the correlating negative in performance accuracy. *Keywords: kinematical- the accuracy- Pool Long- badminton
