The game of tennis is about to get geekier, with Ralph Lauren introducing a high-tech shirt for players.

The so-called 'Polo Tech Shirt' has integrated sensors that measure the wearer's heart rate, respiration, energy output, and stress level. It connects to a separate wearable device with its own accelerometer and gyroscope for measuring movement and direction, and the device then sends all the data to a smartphone over Bluetooth.

Marcos Giron will be the first player to wear the shirt, though he'll only do so during practice. Ralph Lauren claims that Giron will make "adjustments in real time to his play, form and breathing" based on the shirt's data. Several ball boys will also wear the shirt during certain matches.
