The dimensions of the throwing circle have had a basic role in the progress of the throwing technique for the discus. The modern history of the discus throw started thanks to R. Garrett who won in Athens, but A. Oerter instated a more speculative method in terms of the sport science. Based on the literature and twenty years of experience a biomechanical model was developed and based on: 1) thrower having both legs on the ground; 2) time and distance right foot is off ground; 3) time and distance off ground; 4) the path of the discus along the XY and YZ planes; 5) the path of the G.C. along the XY and YZ planes. Moreover the model must point out the spaces within which decelerations occur. The new technical prospects of the throw are directed surely towards: a) the increasing of the plyometric tensions useful to the throw; b) the increasing the take off speed of the discus; c) the decreasing of time and space reserved for deceleration. Variations to this model include a decrease in space and time reserved for the deceleration to benefit the take off speed. The experimental process has followed the phases: a) observations and study of the various techniques; b) theoretical study in order to solve the biomechanical problems of the various techniques; c) applied phase of the theoretical study; d) theorization with a basic programme.
