Today’s GPS smartwatches and other wearable devices give millions of runners reams of data about their pace, location, heart rate and more. But one thing your Garmin can’t measure is plain old physics: How much force is being generated when your foot hits the ground and takes off again.
These backward-forward, braking and propulsion forces a runner generates with each stride are closely associated with performance and injury. Biomechanics experts in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) think wearable sensor technology is poised to help runners better understand these forces and ultimately stay healthier.
A recent study in PLOS One from the lab of Conor Walsh, the Paul A. Maeder Professor of Engineering and...
