Backstroke swimming style
Swimming has four styles and backstroke is one of them. Harry Hebner is the one who popularized this style. It requires swimmer perform on the back flatly and it has the benefit of being easy to breathe since the nose and mouth are above the water, but the downside is that the swimmers are unable to see where they're heading. Backstroke competition first appeared on Olympic game in 1900 at Paris. Ryan Murphy from the USA is the champion at Olympic in men’s 100m backstroke in 2016 and Katinka Housszú from Hungary is the women champion in the same year.
