Boxing is a martial art and 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. Historically, the goals have been to weaken and knock down the opponent.
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. In the event that both fighters gain equal scores from the judges, the fight is considered a draw.
