| Abstract: | Taking Chinese national freestyle aerial athletes as the research subjects,by using the methods of sport biomechanics and with the final aim of making the athletes’ best competitive state to participate in the 21st Winter Olympics,this paper made a comprehensive study on the evaluation and analysis of the athletes’ technology,the characteristics of the muscle power of their lower extremities,as well as the range of impact force for triple through experimental speculation.The achievements are as the following:the range of impact force for the triple has been speculated which will provide a scientific evidence for the safety of female athletes while striving for the success of triple motion;the relations between take-off technology and the stability of landing has been revealed which will be a valid evidence for the perfect completion of air trick together with a stable and safe landing at the same time.It will also be a scientific proof and support for the athletes of the Chinese national team to strive for the completion of difficult air tricks safely and to gain excellent achievements in the 21st Winter Olympics. |
