STLtoday | Parkway School District shelves fitness monitors.

The Parkway School District is taking away activity monitors given to elementary pupils for physical education classes due to a national controversy over privacy issues.

The 75 Polar Active devices, which are worn on the wrist and cost $90 each, were distributed last year to third-, fourth- and fifth-grade pupils at Henry, Ross and Shenandoah Valley elementary schools. The pupils were using them to measure the quality and duration of their exertion during PE classes then comparing those measurements to the U.S. Surgeon General’s recommendations for activity.
