Abstract: The gradual improvement of athletic performance and ability of sports has given rise to higher requirements for the scientific level of training, among which the simulation of athlete 's action is an important research method.Short track speed skating has always been a traditional advantage project inChina. In the competition of 500mshort track speed skating, occupying a good position in the starting phase has an important influence on the whole process of the competition,which can make the athlete enter the corner in advance and thus successfully complete the acceleration phase.The International Skating Union (ISU)changed the rules of start action,as a result various starting actions emerged.Wu Dajing(Champion of Men's 500m in 2016/17 Season),an athlete onthe National Short Track Speed Skating Team, changed his technique of start action and become the only one using lateral type start action in the team.Using the three-dimensional video analysis this paper analyzed the kinematics parameters of start action of Wu Dajing and Canadian athlete Charles Hamelin ,who has been using the lateral starting action, at the 500m competition of 2016/17 ISU World Cup in Shanghai, indicating that technical parameters of the start action of Wu Dajing (center of gravity, trunk angle, pedal ice angle, lower limb joint angle, etc.) are better than that of Charles, and his pedal effect is better than Charles too. It shows that Wu Dajing has a good learning ability of the new technology, it is recommended that he should focus on improving the stability of start actionin the training.
Key words: short track speed skating, start action, virtual kinematicreconstruction, Wu Dajing, new rules
