By Hiroyuki Sato / Yomiuri Shimbun Staff Writer Teijin Frontier Co. has developed sportswear that shows the ratio of the current heart rate to the maximum heart rate by gathering data from sensors installed on the back. It can objectively measure athletes’ degree of fatigue while determining their mental condition, according to Yukihiro Shigemura, the company’s corporate officer. With an eye on introducing the wear for soccer, basketball, track and field and other sports, the company is conducting demonstration tests with multiple sports organizations.
Fujitsu Ltd. is developing a scoring support system jointly with the International Gymnastics Federation. The system will provide assistance for scoring gymnastics and other events. Multiple three-dimensional lasers accurately follow athletes’ physical movements, and AI analyzes knee and elbow angles. At the Tokyo Olympics, Fujitsu aims to have the system adopted in about five out of 10 men’s and women’s events. “We hope the system will be used for training and spectators, too,” company official Hidenori Fujiwara said.
In February, Honda Motor Co. developed a new wheelchair for marathons at the Paralympics.
