Though the Tokyo Olympic Games closed on Aug 8, the public is still watching the athletes. The technologies that helped them in the competition have attracted people’s attention.
Su Bingtian is the first Chinese sprinter(短跑运动员) to reach an Olympic 100 final, setting an Asian record of 9. 83 seconds in his semi-final. “It takes Su 47 steps to run 100 meters. Each step is very important,” a member of Su’s training team said. “Randy Huntington, Su’s American coach and a biomechanics(生物力学) expert in track and field, has collected a lot of data on outstanding sprinters and built a database. He put in all of Su’s data and got a best model. When Su is training, the team uses high-speed cameras to record his training and compares it with the model to find out his weaknesses.”
Technology is also useful in table tennis. On July 27, the semifinal match between China’s Sun Yingsha and Japan’s Mima Ito was going on intensely in Tokyo. You wouldn’t have guessed that a power AI platform was monitoring the match. At an average speed of 100 Mbps, the data was sent to technical team of the Zhejiang University Table Tennis Intelligent Big Data Analysis Platform,2,442 kilometers away from Tokyo.
The platform has stored the data of more than 8, 000 matches so far. The research team has been working on match simulation(模拟) since 2018. “Using big data and AI, we can exactly simulate and predict how the winning rate will change when players change certain tactics(策略).” Professor Wu Yingcai said.
The Tokyo Olympic Games have seen not only scientific support in training, but many newly developed and cutting-edge technologies in athletes’ devices. For example, the Kenya women’s volleyball team’s GPS devices collected data on each player’s strength, heart rate and so on to coaches, who used the information to prevent injury and design training plans for each individual.
