Age of registration for adult boxing competition

A boxer must be at least 18 years old and at least 34 years old. Participants are not allowed to grow beards on the chin, and the maximum length of beards on the upper lip should not exceed the edge of the upper lip. Before each game, the medical examiner must announce whether the players are suitable for the game. Boxers must wear boxing gloves and are only allowed to hit the side and front of their opponents with fists clenched above the waist. At the Sydney Olympic Games, each boxing match consists of four rounds, each lasting two minutes, with a one-minute break between rounds. In the past, every Olympic boxing match had three rounds, each lasting three minutes. However, medical reports show that the new competition system can reduce the physical injury suffered by boxers in the competition.
