The Stillwater Area school district is in the middle of a three-year physical-fitness initiative made possible by federal funding, and, for students, that means sporting high-tech gear measuring activity levels.

Elementary students attach devices to their shoelaces to show how many steps they take and how far they go. Junior high and high school students wear fitness watches that measure heart rates. The devices then send data to a computer, which displays charts on a screen showing how each student's activity levels change.

The devices, plus teacher training, were paid for by a grant from the Carol M. White Physical Education Program. Grant recipients are required to offer instruction in healthy eating habits and develop fitness activities.
