When was the first time that butterfly stroke was done swimming?
In 1934, however, David Armbruster, coach at the University of Iowa, devised a double overarm recovery out of the water. This “butterfly” arm action gave more speed but required greater training and conditioning. Then in 1935, Jack Sieg, a University of Iowa swimmer, developed the skill of swimming on his side and beating his legs in unison like a fish’s tail. He then developed the leg action face down. Armbruster and Sieg combined the butterfly arm action with this leg action and learned to coordinate the two efficiently. With two kicks to each butterfly arm action, Sieg swam 100 yards in 1:00.2. This kick was named the dolphin fishtail kick. Even though the butterfly breaststroke, as it was called, was faster than the breaststroke, the dolphin fishtail kick was declared a violation of competitive rules. For the next 20 years, champion breaststrokers used an out-of-water arm recovery (butterfly) with a shortened breaststroke kick. In 1953, the butterfly stroke with the dolphin kick wa
