Amateur wrestling is a variant of wrestling practiced in collegiate, school, or other amateur level competitions. There are two international wrestling styles performed in the Olympic Games: freestyle and Greco-Roman. Both styles are under the supervision of the United World Wrestling (UWW; formerly known as FILA, from the French acronym for International Federation of Associated Wrestling Styles). A similar style, commonly called collegiate (also known as scholastic or folkstyle), is practiced in colleges and universities, secondary schools, middle schools, and among younger age groups in the United States. Where the style is not specified, this article refers to the international styles of competition on a mat. In February 2013, the International Olympic Committee (IOC) voted to remove the sport from the 2020 Summer Olympics onward. On 8 September 2013, the IOC announced that wrestling would return to the Summer Olympics in 2020. The rapid rise in the popularity of the combat sport mixed martial arts (MMA) has increased interest in amateur wrestling due to its effectiveness in the sport and it is considered a core discipline. Scoring Greco-Roman and freestyle differ in what holds are permitted; in Greco-Roman, the wrestlers are permitted to hold and attack only above the waist. In both Greco-Roman and freestyle, points can be scored in the following ways: Takedown: A wrestler gaining control over their opponent from a neutral position. Reversal: A wrestler gaining control over their opponent from a defensive position. Exposure or the Danger Position: A wrestler exposing their opponent's back to the mat, also awarded if one's back is to the mat but the wrestler is not pinned. Penalty: Various infractions (e.g. striking the opponent, acting with brutality or intent to injure, using illegal holds, etc.). (Under the 2004–2005 changes to the international styles, a wrestler whose opponent takes an injury time-out receives one point unless the injured wrestler is bleeding). Any wrestler stepping out of bounds while standing in the neutral position during a match is penalized by giving their opponent a point. Scores only awarded in collegiate wrestling As in the international styles, collegiate wrestling awards points for takedowns and reversals. Penalty points are awarded in collegiate wrestling according to the current rules, which penalize moves that would impair the life or limb of the opponent. However, the manner how infractions are penalized and points awarded to the offended wrestler differ in some aspects from the international styles. Collegiate wrestling
