The NBA's studying wearable monitors. Will players soon wear them during games?

The NBA is funding a study of wearable sensors to be performed at the Mayo Clinic. It will test devices from market leaders Catapult and STATSports. The devices use GPS to provide a variety of metrics, including distance traveled and heart rate, as well as advanced information like a player's acceleration. They can tell users if a player is pushing off one of his legs harder than the other, a possible sign of injury. A Catapult monitor was used during some of the NBA's minor league games, and they may soon be used during regular season NBA games as well, though this would require the approval of the players' union. The data could be used to keep players safer; fatigue is associated with injury, and analytics contributed to the league's decision to give players more rest time in between games. But unsurprisingly, the monitors also raise ethical concerns. Should teams be allowed to use personal data against a player during contract negotiations? More
