By combining virtual reality, the digital twin system has been deeply applied in many places. Especially with the upsurge of national sports and more attention to sports, people have also begun a more in-depth study on the strategy of sports training. This paper aims to explore the application of the Brazilian jujitsu training strategy and interactive control method in the new era. Based on the sports skills of Brazilian jujitsu, combined with digital twin technology and wireless sensor network technology, this paper develops a sports training system based on Brazilian jujitsu. It can collect the action information of the trainer and twin it into the simulation system so as to carry out better and more effective confrontation training. The experimental results show that the average delay time is 5.2 ms and the maximum delay time is 6.5 ms, which is less than the limit delay time of 20 ms. Compared with the control group, it achieved quite good results. It shows the effectiveness of the system designed in this paper for trick jujitsu training.
