China has took the lead in the Tokyo 2020 medal table and according to the China Aerospace Science and Technology Corporation (CASC), competitors had some high-tech help on their way to Tokyo. Using "aerospace measurement products", six world champions, including women's 200m butterfly winner Zhang Yufei, refined their techniques for the 2020 Games. "Through data analysis, they helped athletes formulate training programs scientifically and provided scientific support to improve the performance," the CASC said.
