Boxing is a combat sport in which two people engage in a contest of strength, speed, reflexes, endurance, and will, by throwing punches at each other, usually with gloved hands. Traditionally, the goal has been to knock the opponent unconscious from a blow to the head.
Amateur boxing is both an Olympic and Commonwealth sport and is a common fixture in most international games it also has its own World Championships. Boxing is supervised by a referee over a series of one- to three-minute intervals called rounds. The result is decided when an opponent is deemed incapable to continue by a referee, is disqualified for breaking a rule, resigns by throwing in a towel, or is pronounced the winner or loser based on the judges' scorecards at the end of the contest.
