Butterfly stroke: Difference between revisions

The butterfly style evolved from the breaststroke. [[David Armbruster]], swimming coach at the [[University of Iowa]], researched the breaststroke, especially considering the problem of drag due to the underwater recovery. In [[1934]] Armbruster refined a method to bring the arms forward over the water in a breaststroke. He called this style "butterfly". While the butterfly was difficult, it brought a great improvement in speed. One year later, in [[1935]], [[Jack Sieg]], a swimmer also from the [[University of Iowa]], developed a kick technique involving swimming on his side and beating his legs in unison, similar to a fish tail, and then modified the technique afterward to swim it face down. He called this style ''Dolphin fishtail kick''. Armbruster and Sieg quickly found that combining these techniques created a very fast swimming style consisting of butterfly arms with two dolphin kicks per cycle.
