P.V. Sindhu, the double Olympic medalist from India, has garnered attention at the Thomas and Uber Cups in Horsens, Denmark, for wearing a new device known as the 'temple', developed by Zomato founder Deepinder Goyal. This innovative wearable tracks metrics such as blood flow and cognitive function in real-time, aiming to enhance athletic performance. In her opening match, Sindhu triumphed over Denmark's Line Christophersen in a thrilling three-game contest, showcasing her determination to compete in the upcoming 2028 Olympics. Sindhu's husband, Venkata Datta Sai, who supports her in this venture, noted that they are currently testing the device with promising initial results. Although it is not yet commercially available, the 'temple' could potentially revolutionize how athletes monitor their performance if proven effective. Sindhu expressed her excitement about the matches and her ongoing commitment to improving her game.
