The establishment of the IPF in 1973 spurred the establishment of the EPF (European Powerlifting Federation) in 1974. Since it was closely associated with bodybuilding and women had been competing as bodybuilders for years, the new sport was opened to them very quickly. The first U. S. national championships for women were held in 1978 and the IPF added women's competition in 1979. In the US, the Amateur Sports Act of 1978 required that each Olympic or potential Olympic sport must have its own national governing body by November 1980. As a result, the AAU lost control of virtually every amateur sport. The USPF was founded in 1980 as the new national governing body for American powerlifting. Soon, controversy over drug testing would cause powerlifting to splinter into multiple federations. In 1981, the American Drug Free Powerlifting Association (ADFPA), led by Brother Bennett, became the first federation to break away from the USPF, citing the need to implement effective drug testing in the sport. Meanwhile, the IPF was moving towards adopting drug testing at international meets, and requiring member nations to implement drug testing at national meets as well. In 1982, drug testing was introduced to the IPF men's international championship, although the USPF championships that year did not have drug testing.
