The aim of this study was to gain the knowledge about kinematic and technical parameters required for acceleration of whole body in rotational shot put technique, using three-dimensional motion analysis. 12 male shot putters participated this study. From the results, linear momentum during double support phase (DSP) (r = 0.64, 0.79, p < 0.05, 0.01) and angular momentum during flight phase (FP) and 2nd single support phase (SSP2) (r = 0.58-0.72, p < 0.05, 0.01) were closely related with throwing record, and these parameters would indicate the acceleration of whole body. In addition, path length of center of gravity at DSP related with linear momentum (r = 0.75, p < 0.01). And the velocity of right toe, right elbow and left heel were closely related with angular momentum during FP and second single support phase (SSP2). These results can be concluded that enhancement these parametars will be effective techniques for acceleration of whole body.
