Some Physics behind Sumo Wrestling

The following video provides an introduction to the popular Japanese sport of Sumo Wrestling. 




Why does the Sumo Wrestler maintain a "Bottom-Heavy" Body and wrestles with legs wide apart?

Remember the objective in order to win is to be able to knock the opponent down or out of the ring. Therefore, it is of paramount importance that the body of each individual sumo wrestler be made as stable as possible. 

Recall the two conditions of increasing stability:
Increase the base area
Lower the centre of gravity

Hence, the reason why the wrestlers maintain a "Bottom-Heavy" Body is to ensure that centre of gravity is made as low as possible. 

Also, the reason the wrestlers stand with their legs apart is to increase the base area of their bodies. 

With these two factors considered, they can improve their stability and increase their chances of winning the match! =)
