A good delivery will allow the thrower to transfer all the forces he has created during the spin and tension of his body into the implement. Therefore he needs 1-To stop turning -Using the left side blocking 2-To deliver the implement on the right path with the most appropriate angle – 3-To add the last accelerations from the trunk-throwing arm and fingers . He also needs during that time to have a solid and stable position. In this document , a commented still picture , the Cuban Luis DELIS (PB 71,06m) , a top world class thrower in the eighties , shows the perfect discus delivery position.
