        This study was conducted to identify the effective teaching methods of short put. The subjects who participated in this study comprised the high performance players(N=3) and the low performance players(N=4). A three-dimensional cinematographic method using DLT was used to analyze motions in shot put. The results of this study included the following important things: 1.Making glide long within a very limited time was contributing to the improvement of the record. 2.The large gait in shot put was considered as an unappropriated factor because it makes the reduction of using a flat force. 3.Releasing high on the condition that the high of central gravity of the body is stable is one of the ways to make good distance. 4.The releasing angles of the high performance players were smaller than those of the low performance players. 5.The knee angles of the high performance players were 95.7±2.517˚ while the glided foot landed in thee center of the circle. And, the knee angles of these players were 135±3.000˚ while the other foot landed completely. 6.The quickly releasing velocity of the shot put was found to be a better chance to make a good distance.
