Abstract
In this study, a fourth year primary school physical education class including eight lessons of sumo held twice six months apart were observed to check the retention of the initial and long-term effects of these lessons in terms of “awareness of the body,” “suppression of the venting of aggressive emotion,” and “ability to control muscle output”. The study results show that all of the effects built up during the first session, were maintained after six months. It is inferred that “awareness of the body” is further enhanced by improved physical skills as a result of the repeated sessions of sumo. The study results also suggest that a deeper understanding of the emotion of opponents acts to further suppress the “venting of aggressive emotion” as such understanding increases the sense of tolerance towards the opponents.
