Dan BanHuaXue Englishword is Snowboard, the sport is born inAmerica in 1960s, its cause is related to surf riding. Since itwas introduced in China since 2003, by long-termtraining and groping, China has achieved certain performance in the event, at present it also is Chinese relative advantageous snowsport.Among them, takeoff height is the key to flight phase, motions difficulties, motion quality as well as fluency in the air decides athletesÂ’ performances and also competitions final results. The paper, by proper hypothesis, simplified models, according to principle of conservation of energy, it analyzes and solves dynamics and sport state to athletes, gets flight height differential equation, and analyzes each factor influences on flight height. From the perspective of objective theory, it discusses increasing flight height method, and gets technique how to increase flight height
