The purpose of this study is to obtain the stable and accurate techniques of free throw shooting motion in basketball through kinematic data. The subjects of this study were six male basketball players consisted of college students athletes. Five trials were sampled with two high speed video cameras for each subjects at 60fields/s, but only one was selected for analysis. The DLT method was used to obtain the 3-dimensional coordinates of the body landmarks. The recorded images was digitized with Kwon3D Motion Analysis Package(Version 2.1). And the range of analyzing was from the instant when the knee was most flexed(E1) to the instant when the ball was projected in hand(E2). The conclusions were as follows ; 1. To the stabilized and correct projection motion, the change of the center of gravity displacement of subjects must small. And during free throw shooting motion, the trunk of subjects must build near to vertical. 2. The elbow and shoulder joint of subjects must flexed so that near to line of C.O.G at lowest position of knee joint event. And during projection of ball, the elbow of subjects must extend to upward. 3. During lowest position of the knee joint event, the wrist and hand of subjects must increase the time of contact in ball. And during projection of ball, the wrist of subjects must flex for the snap of wrst to foward in the releasing event according to the projection distance.
