Single Boxing
Single boxing is a combat sport where fighters fight against each other. A boxing round is not extended. However an official may end the bout before the end of the round to signal that the round is over or that one of them cannot continue the fight. Sometimes, a referee can end a round if one or both of the competitors is knocked out and is unable to continue the fight. This is called a technical disqualification. In the 1990s the IOC introduced computer scoring in single boxing. Each judge was equipped with a keyboard that was equipped with blue and red buttons. The button was pressed in the region where the scoring blow was. Legal scoring blows have to touch the knuckle of boxer's gloves and fall within the scoring zone, from the middle of their heads, all the way to the sides of their chests and between their hips and the belly button. The technique is based on the idea that boxers use their hands to defend himself and a successful punch will redirect an opponent's punch.
