Wrestling, sport practiced in various styles by two competitors, involving forcing an opponent to touch the ground with some part of the body other than his feet; forcing him into a certain position, usually supine (on his back); or holding him in that position for a minimum length of time. Wrestling is conducted in various styles with contestants upright or on the ground (or mat). The three basic types of wrestling contest are the belt-and-jacket, catch-hold, and loose styles, all of which appear to have originated in antiquity. Belt-and-jacket styles of wrestling are those in which the clothing of the wrestlers provides the principal means of taking a grip on the opponent.
