A number of “black technologies” appeared in the Tokyo Olympic Games

In the ongoing Tokyo Olympics, not only are athletes from various countries sweating and competing for gold medals, but new technologies such as wearable technology and artificial intelligence technology have quietly sneaked in, becoming a powerful boost to promote athletes to achieve better results.

According to reports, “3D athlete tracking technology” will appear for the first time in the track and field competitions of the Olympic Games. It can provide data on the athlete’s speed, body angle, acceleration, step length, etc. within a few seconds, and realize the data extraction of the athlete’s 3D form. This is information that athletes and coaches could not capture with the naked eye in the past. This technology is not only a good record of the athletes’ training, but also a brand-new way of broadcasting-analyzing, interpreting and reviewing the highlights of the game in real-time playback, which can bring a brand new experience to the Olympic audience.

According to the NHK website of Japan, the International Gymnastics Federation has introduced an artificial intelligence (AI) technology scoring assistance system developed by Japan’s Fujitsu. The system tracks the player’s movements by projecting infrared rays onto the player’s body and its surroundings, and converts it into a three-dimensional image in real time. According to the images, AI can analyze the body’s rotation and twisting and other subtle movements, and combine the past game data to judge the completion of the technology according to the scoring standards.

Hong Kong’s “South China Morning Post” website stated that athletes participating in the Tokyo Olympics also use cutting-edge technology and equipment to improve their performance. Among them, wearable sports technology has become one of the “arsenal” of elite athletes competing for gold medals. It can monitor the athlete’s heart rate, breathing and other states to improve sports performance. The coach can adjust the training method according to the real-time information of the athlete’s status. According to the report, the Kenyan women’s volleyball team uses wearable devices to provide coaches with data on each athlete’s strength, heart rate and other important indicators. Coaches use this information to prevent injuries and tailor a training system for each individual. The Danish Sports Technology Company uses radar-based equipment to help the Japanese baseball team analyze the pitching or hitting situation in order to evaluate the performance of the players.

However, some people are worried about this trend. Dr. Bryce Dale, deputy director of the Department of Engineering and Design at Bournemouth University in the United Kingdom, believes that technological advancement may have an adverse effect on the long-term participation of athletes in developing countries: after all, many new sports-assisted technology products are expensive.
