Nike, Inc and Polar have introduced the Polar WearLink+ that works with Nike+, enabling users to run and train with heart rate monitoring.

The equipment is worn round the chest and transmits the user's heart rate wirelessly to their Nike+  iPod Sport Kit or Sportband. Users can see their beats per minute while they run with their Nike+ SportBand, or hear spoken feedback of their BPM during their Nike+ iPod workout. And after training, heart rate data can be transferred to the web service.

The soft textile chest strap seamlessly adapts to the user's body shape, bringing full freedom of movement to the training session. The comfortable textile strap is also machine-washable and with its hook mechanism, the transmitter is just as quick to put on as it is to take off. A user replaceable battery also increases the ease-of-use.

“Nike users around the globe can now benefit for the first time from pioneering Polar heart rate monitoring technology,” says Marco Suvilaakso, Group Product Director at Polar. “The new WearLink+ transmitter Nike+ will make accurate heart rate training available to millions of Nike+ users. It will add a new dimension to their training enabling them to train at the right intensity to achieve their goals. We anticipate this will be a very popular product.”

The Polar WearLink+ will be available from June 2010 in the U.S., followed by Canada and major EU countries from the beginning of July.
