Analysis Of Technical Characteritics Of Elite Women Backstroke Athletes

By observing the women's 50,100,and 200 meter final video in the 2014,2015 and 2016 Championships,this paper collects the kinematic parameters of the four stages of athletes' departure,journey,turn,and sprint and touches the wall,and uses the literature method,video analysis,mathematical statistics,case analysis and interview methods for the athletes of 8 games.Kinematic parameters were sorted,analyzed,summarized and concluded.1? Our elite female back stroke swimmers' R.T.are slower than the world elite female back stroke swimmers.2? Our elite female back stroke swimmers have the characteristics of decreasing the frequency and increasing the range in swimming.3? Our elite female back stroke swimmers have decreased the speed of the last 5 meters compared to the middle-part's speed,and lack of speeding up to the edge before the turning.
