Theater in New York lasted eight hours before ending in a draw. Even in the 1912 Olympics, a match between Martin Klein of Russia (Estonia) and Alfred Asikainen of Finland lasted for eleven hours and forty minutes before Martin Klein won. He received the silver medal because he was too tired to compete in final match next day. That record was later published at Guinness World Records. The International Amateur Wrestling Federation (IAWF) took over the regulation of Greco-Roman wrestling in 1921. Since then matches have been dramatically cut short, and today all movements that put the life or limb of the wrestler in jeopardy are forbidden. Professional wrestler Lou Thesz, who initially trained extensively in Greco-Roman, popularised the Greco-Roman backdrop during early televised professional matches. In Olympic competition, countries of the former Soviet Union, Bulgaria, Turkey, South Korea, Romania, Japan, Sweden, and Finland have had great success. Carl Westergren of Sweden won three Greco-Roman gold medals in 1920, 1924, and 1932, and was the first Greco-Roman wrestler to do so. Alexander Karelin did the same in 1988, 1992, and 1996. Ivar Johansson of Sweden won gold medals in Greco-Roman in 1932 and 1936 and also a gold medal in freestyle in 1932. The United States Olympic delegation (exclusively wrestling freestyle before) first entered Greco-Roman wrestling in 1952 and has taken three gold medals, won by Steve Fraser and Jeffrey Blatnick in the 1984 Los Angeles Olympic Games, and by Rulon Gardner at the 2000 Olympic Games in Sydney, Australia. Weight classes Currently, international Greco-Roman wrestling is divided into four main age categories: schoolboys, cadets, juniors, and seniors. Schoolboys (young men ages 14–15; or age 13 with a medical certificate and parental authorization) wrestle in 10 weight classes ranging from 29 to 85 kg. Cadets (young men ages 16–17; or age 15 with a medical certificate and parental authorization) wrestle in 10 weight classes ranging from 39 to 100 kg. Juniors (young men ages 18 to 20; or age 17 with a medical certificate and parental authorization) wrestle in eight weight classes ranging from 46 to 120 kg. Seniors (men ages 20 and up) wrestle in seven weight classes ranging from 50 to 120 kg. For men, there is also a special category for some Greco-Roman competitions, "Veterans", for men ages 35 and older, presumably featuring the same weight classes as seniors. Also, all of the men's age categories and
