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.
Claims20
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, and
- c) electronically displaying the metabolic energy expenditure.
A device for measuring the metabolic energy expended by a human subject comprising:
- a) means for measuring the contact time (t) of the foot of a human subject against a rigid surface,
- b) means for calculating the energy expenditure (E) of said human subject based on the weight of the subject (W) divided by the contact time t, and
- c) means for electronically displaying the energy expenditure.
