Olympic boxing

Amateur boxing (also called Olympic boxing) is a variant of boxing practised at the collegiate level, at the Olympic Games, Pan American Games and Commonwealth Games, as well as many associations.

Amateur boxing bouts are short in duration, comprising three rounds of three minutes in men, and four rounds of two minutes in women, each with a one-minute interval between rounds. Men's senior bouts changed in format from four, two-minute rounds to three, three-minute rounds on January 1, 2009. This type of competition prizes point-scoring blows, based on number of clean punches landed, rather than physical power. Also, this short format allows tournaments to feature several bouts over several days, unlike professional boxing, where fighters rest several months between bouts.

Competitors wear gloves. Head protection was used in men's competition until March 2016, before it was removed by the AIBA due to a higher concussion rate with Head Protection. However, women's boxing will continue with Head Protection, after the AIBA announced that they did not have enough data to decide if there was higher risk of concussion in women.

A referee monitors the fight to ensure that competitors use only legal blows (a belt worn over the torso represents the lower limit of punches - any boxer repeatedly landing "low blows" is disqualified). Referees also ensure that the boxers don't use holding tactics to prevent the opponent from swinging (if this occurs, the referee separates the opponents and orders them to continue boxing. Repeated holding can result in a boxer being penalized, or ultimately, disqualified). Referees will stop the bout if a boxer is seriously injured, or if one boxer is significantly dominating the other. Bouts which end this way may be noted as "RSC" (referee stops contest), RSCI (referee stops contest due to injury), RSCH (hard blows to the head), or KO (boxer out for ten seconds).

Amateur boxing emerged as a sport during the mid-to-late 19th century, partly as a result of the moral controversies surrounding professional prize-fighting. Originally lampooned as an effort by upper and middle-class gentlemen to co-opt a traditionally working class sport, the safer, "scientific" style of boxing found favor in schools, universities and in the armed forces, although the champions still usually came from among the urban poor.
