The International Association of Red Sports and Gymnastics Associations, commonly known as Red Sport International (RSI) or Sportintern was a Comintern-supported international sports organization established in July 1921. The RSI was established in an effort to form a rival organization to already existing "bourgeois" and social democratic international sporting groups. The RSI was part of a physical culture movement in Soviet Russia linked to the physical training of young people prior to their enlistment in the military. The RSI held 3 summer games and 1 winter games called "Spartakiad" in competition with the Olympic games of the International Olympic Committee before being dissolved in 1937.[1]
