United States Kickboxing Association
 The first American sanctioning body to regulate kickboxing matches the United States Kickboxing Association (USKA) was established in early 1970 by former Green Beret Lee Faulkner following his promotion of North America’s debut kickboxing bout featuring Joe Lewis’ knockout victory over Greg Baines. The USKA’s rules permitted kicking punching knee and elbow strikes and footsweeps. Only crescent kicks and round kicks were allowed to the head.
