Amateur boxing may be found at the collegiate level, at the Olympic Games and Commonwealth Games, and in many other venues sanctioned by amateur boxing associations. Amateur boxing has a point scoring system that measures the number of clean blows landed rather than physical damage. Bouts consist of three rounds of three minutes in the Olympic and Commonwealth Games, and three rounds of three minutes in a national ABA (Amateur Boxing Association) bout, each with a one-minute interval between rounds.
Competitors wear protective headgear and gloves with a white strip across the knuckle. A punch is considered a scoring punch only when the boxers connect with the white portion of the gloves. Each punch that lands cleanly on the head or torso with sufficient force is awarded a point. 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 (below the belt) 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, if one boxer is significantly dominating the other or if the score is severely imbalanced. Amateur bouts which end this way may be noted as “RSC” (referee stopped contest) with notations for an outclassed opponent (RSCO), outscored opponent (RSCOS), injury (RSCI) or head injury (RSCH).
