Aprender

is a martial art and combat sport in which two people engage in a contest of strength, reflexes, and endurance by throwing punches at an opponent with the goal of a knockout with gloved hands.
Amateur boxing is an Olympic and Commonwealth sport and is a common fixture in most of the major international games - it also has its own World Championships. Boxing is supervised by a referee over aseries 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.
The birth hour of boxing as a sport may be its acceptance by the ancient Greeks as an Olympic gameas early as 688 BC. Boxing evolved from 16th and 18th century prizefights (detailed further down the page), largely in Great Britain, to the forerunner of modern boxing in the mid 19th century, again initially in Great Britain and later in the United States. In 2004, ESPN ranked boxing as the most difficult sport in the world.
rules
A boxing match typically consists of a determined number ofthree-minute rounds, a total of up to 12 rounds (formerly 15). A minute is typically spent between each round with the fighters in their assigned corners receiving advice and attention from their coach and staff. The fight is controlled by a referee who works within the ring to judge and control the conduct of the fighters, rule on their ability to fight safely, count knocked-down fighters, and ruleon fouls. Up to three judges are typically present at ringside to score the bout and assign points to the boxers, based on punches that connect, defense, knockdowns, and other, more subjective, measures. Because of the open-ended style of boxing judging, many fights have controversial results, in which one or both fighters believe they have been "robbed" or unfairly denied a victory. Each fighterhas an assigned corner of the ring, where his or her coach, as well as one or more "seconds" may administer to the fighter at the beginning of the fight and between rounds. Each boxer enters into the ring from their assigned corners at the beginning of each round and must cease fighting and return to their corner at the signaled end of each round.
A bout in which the predetermined number ofrounds passes is decided by the judges, and is said to "go the distance". The fighter with the higher score at the end of the fight is ruled the winner. With three judges, unanimous and split decisions are possible, as are draws. A boxer may win the bout before a decision is reached through a knockout; such bouts are said to have ended "inside the distance". If a fighter is knocked down during thefight, determined by whether the boxer touches the canvas floor of the ring with any part of their body other than the feet as a result of the opponent's punch and not a slip, as determined by the referee, the referee begins counting until the fighter returns to his or her feet and can continue. Should the referee count to ten, then the knocked-down boxer is ruled "knocked out" (whether unconsciousor not) and the other boxer is ruled the winner by knockout (KO). A "technical knockout" (TKO) is possible as well, and is ruled by the referee, fight doctor, or a fighter's corner if a fighter is unable to safely continue to fight, based upon injuries or being judged unable to effectively defend themselves. Many jurisdictions and sanctioning agencies also have a "three-knockdown rule", in whichthree knockdowns in a given round result in a TKO. A TKO is considered a knockout in a fighter's record. A "standing eight" count rule may also be in effect. This gives the referee the right to step in and administer a count of eight to a fighter that he feels may be in danger, even if no knockdown has taken place. After counting the referee will observe the fighter, and decide if he is fit to...
