NBA to Use Players’ Bodies in Statistical Analysis Sports First

The National Basketball Association already is using statistical analysis technology on the court. Soon, it may be using it on players’ bodies, too.

The NBA said players in its Development League are using performance analytic devices attached to their bodies. The D League, which is the NBA’s training ground as well as research and development lab, is the first U.S. sports league to use them on players during regular-season games, the NBA said.

About 20 of the NBA’s 30 teams are using the one-ounce devices during practice, said the league, which will announce the program tomorrow at its Technology Summit at All-Star weekend in New Orleans.

The devices are worn by players under their jerseys with either a small disc attached to their chest, or inside an undergarment pouch between the shoulder blades.

During games, the NBA said, the devices will assist in maximizing player performance and health by generating data on things like cardiovascular exertion, musculoskeletal intensity, fatigue, rate of acceleration and deceleration, number of jumps and distance and direction run.

The NBA this season began video tracking in every arena, becoming the first U.S. league to quantify and analyze every movement of live games over an entire season.

Major League Soccer, some European soccer leagues and Australian rugby teams are testing similar technologies, the NBA said.

The D-League includes 14 teams with direct NBA affiliations.
