Through an experience of researchers in the area of game Badminton biomechanics, they found a vulnerable for the squad Diyala University badminton in accuracy of and directing crushing blow, is illustrated by through an ease of response to the overwhelming blow faced by the our players, and in the areas be close on the opponent and in places of is inaccurate, plus other fitness requirements, , And the goal is identify some variables points Kinematic body noted by the crushing performance the beating skill, And also to identify the relationship between some variables AlKinematic accurately crushing the beating performance. The of researchers adopted on the descriptive approach and great number of players four, statistical data was processed on system (SPSS), The most important conclusions is a relationship were not significant correlation between some variables AlKinematic and accuracy crushing blow and of higher body mass center of moment beating, hat variable angle Milan trunk, significant impact on increasing the speed the racket peripheral speed badminton.
