Open weight sumo wrestler Olga Davydko glares at her opponent before the start of their match, hoping to up the intimidation factor. Unlike Greco Roman wrestling, which is contested at the Olympics and scored based on performance, sumo wrestlers try to force their opponents to touch the ground with any body part other than the soles of their feet, or push them out of the wrestling ring. Most matches only last a few seconds, but some can last several minutes.
