1. A method for measuring the energy expended by a human subject during walking or running, said method comprising the steps of:
- a) detecting the contact time (t) of the foot of said human subject against a rigid surface,b) calculating the metabolic energy expenditure (E) of said human subject base on the weight of the subject (W) divided by the contact time t, andc) electronically displaying the metabolic energy expenditure.

Abstract
This invention relates to a device and method for determining the metabolic energy expenditure by a human during periods of running or walking. The energy expenditure is correlated with the weight of the subject (W) divided by the time of foot contact with a hard surface (t). This relationship can be programmed into a portable device for the direct measurement of both the rate of energy expenditure and the total energy expended.
