1. The Sport, the Three Styles and How a Bout Is Won
1.1 Object of Wrestling
Wrestling is a one-on-one grappling combat sport in which each wrestler seeks either to "pin" (fall) the opponent or to win on points. Two wrestlers — distinguished as red and blue by the colour of their singlet — meet in a single bout on a circular mat. There are no draws: every bout produces one winner and one loser. The bout is directed by a referee on the mat, supervised by a judge and a mat chairman who together control scoring, cautions and the fall.
1.2 Greco-Roman, Freestyle and Women's Wrestling
UWW governs three Olympic styles under this single ruleset. In Greco-Roman Wrestling it is strictly forbidden to grasp the opponent below the belt line, to trip, or to use the legs actively on the opponent. In Freestyle Wrestling it is permitted to grasp the legs, to trip, and to use the legs actively to perform any action. Women's Wrestling follows the Freestyle rules, but the Double Nelson is forbidden. Beach Wrestling, Pankration, Belt Wrestling, Grappling and Traditional Wrestling are governed by separate regulations.
1.3 The Ways a Bout May Be Won (Article 29)
A bout may be won in any of the following ways: (1) by fall (pinning both of the opponent's shoulders); (2) by injury (the opponent cannot continue); (3) by 3 cautions given to the opponent during the bout; (4) by technical superiority (the required point gap is reached); (5) by forfeit; (6) by disqualification; or (7) by points — having at least 1 point more after the addition of the two periods. Detailed classification points for each result type are set out in Article 41 (Chapter 7).
