Translated from French and also called ”decide your technique in the rotational shot put” . This exceptional document publishes all the content of the lecture done by Didier POPPE in the Strasbourg march 2019 coaching conference.. It is a technical and biomechanical study of the different options which are used by some of the best world throwers with 5 rather different ”techniques” :1- the ”turn-Kick-turn” most used technique inherited from the discus approach, -2- The ”Turn-Twist-Throw” specific to Adam NELSON -3- the ”Turn-Flex-Jump” illustrated by Brian OLDFIELD – 4- The ”Turn-Flex-Transfer” of young Jacko GILL which combined rotation and linear delivery , and -5- The technique of the multiple accelerations which seems to be developed by Thomas WALSH making some successful researches and compromises with the other techniques. Something to study and think about to become a reference document for those who are interested by the rotational shot put techniques development possibilities . Out of that maybe a good help for the coaches and athletes to pick what is good for them and not just try to copy the reigning champion.
