New simple method determines rate at which we burn calories walking up, down, flat

http://ift.tt/eA8V8J A new way to predict the energy a person expends walking will help predict and monitor the physiological status of walkers, including foot soldiers. Researchers have developed the Army-funded method, which significantly improves on two existing standards, and relies on three readily available variables. Accurate prediction is important because the rate at which people burn calories walking can vary tenfold depending on speed, carried load and whether uphill, at-grade or downhill.
