Abstract
The purpose of this study is to describe in detailed examples of the practice process leading up to the implementation of “Cassina” in a competition and exploring effective consciousness. The subject is an athlete who won a silver medal in the gymnastics team final at the Tokyo 2020 Olympic Games. It became clear that practicing with an awareness of the giant in the preparation phase is important to catch the bar in “Cassina”. Especially, in the acceleration phase, it is important to maintain straight body and the toes go through as far as possible. In the preflight phase, it is crucial to arch outwards.
