Recently, the Shanghai World Tour has become a hot race. Phelps, which everyone hoped for, had another new "weapon," a sportswear with sensors. The weapon was supplied by a famous Under Armor brand that he endorsed, and the brand opened its first China store in Shanghai. Speaking of this "secret weapon," founder Kevin said, "Previously, Phelps had put on our 'E39' training, and he said it was not bad, and he was amazed at how powerful it was in a small garment Features." This new swimsuit, called the "E39", uses a state-of-the-art technology that puts a special sensor-equipped swimsuit that sends a signal to a computer to monitor Phelps's physical condition through a computer at the field, such as Body temperature, heart rate, breathing and so on. So he can understand his degree of fatigue, can effectively adjust their own pace. Kevin also said that the technology has been widely used in the NFL in the United States.
