| Freestyle skiing aerials belong to difficulty-artistic event-group.The project is dividedinto help slip technology, leaving the platform technology, Air skills and Landing technologyfour parts. Each part of the freestyle skiing aerials have played a decisive influence on thefinal result. This paper does a statistical analysis of the kinematics index of the freestyleskiing air skills from the leaving the platform technology and landing technology two aspects.The aim is to perfect Sports training monitoring systemof freestyle skiing air skills project,find out the the key of evaluation and diagnosis index which decide the project success and toprovide the science theory protection to better promote the content of science of sportstraining and technology and athletes to complete action in high quality.Through the Plane fixed-point shooting method for freestyle skiing air movement skillsimage of our National team players, using motion analysis System for the APAS Systemkinematics parameters, and do correlation analysis on characteristics.The results of the study show thatMan three weeks on vertical speed is one of the larger sensitive diagnostic indices on theair vertical height of leaving platform linear index. But for women’s two weeks action, thedistance of help smooth is the biggest sensitive index on influencing athletes air verticalheight. And help smooth the distance is improve the athletes’ physical movement speed keyfactors.The sensitive diagnosis index which influence success of man three weeks action is theCenter of gravity speed and help sliding speed in the highest point; for Woman2weeks actionis the Center of gravity speed in the highest point and level speed of leaving platformSuggestions: Coaches and athletes should be paying more attention to the sensitivediagnostic indices of regulation in daily training or competition process, controling each jointangle and linear diagnostic indices in reasonable area. |
