[Abstract]:The gradual improvement of the performance and ability of competitive sports puts forward higher requirements to the scientific level of training, among which the simulation of athletes' movement reproduction is an important research method and means. 3DVR (3D Virtual reality) technology, with its strong interactivity, real-time and immersion, has become an important means of data reconstruction and demonstration in the process of science and technology services. Short track speed skating has always been a traditional advantage event in our country. In the 500m short track speed skating race, the starting stage occupies a favorable position and has an important influence on the whole process of the race. It can lay a good foundation for the following running.After the International Slide Federation modifies the start rules of short track speed skating in 2015, the starting technology will be diversified. In this paper, using three-dimensional video analysis method, the Canadian famous athlete Charles Hamelin, who has been using the lateral start and has been using the lateral start, has been used in the 500m short track speed skating World Cup Shanghai Station of the 2016 / 17 International Slide Federation. To parse the technology, The kinematics data are transferred into the virtual reality system for 3D reconstruction demonstration, and then comparative analysis is carried out. The research shows that the effect of Wudajing in this race is slightly better than that of Charles. It shows that Wudajing has a strong ability to learn and master new technology. It is suggested that the training process should pay attention to the practice of starting reaction ability. Increase the stability of the starting movement, and strengthen the strength of the right lower extremity.
