Kinematic Analysis on Chinese Female Athletes bFdF Action in Freestyle Skiing Aerialse

In order to improve aerials skills in monitoring, this article analyzes the kinematic parameters of the difference between successful and failed landings of bFdF action. Study on some Chinese master- standard female athletes ' start-down speed, in-run distance, as well as the kinematic parameters of kicker-leaving and landing moment by means of movement-image analysis and statistic analysis, then compare them between successful and failed situations. The result shows that the start-down speed is significantly different between success and failure. At the moment of completely leaving the kicker, the following means of successful landings are bigger than the failed ones: knee-banding degrees, shoulder angle, torso-forward angle, vertical speed of center of gravity. At the moment of landing, the shoulder angle is significantly different between success andfailure.
