Exercise Monitor
First Claim
1. A device for measuring the aerobic capacity of a subject, the device comprising input means for receiving a measurement of distance travelled by a user in a given time, said time being sufficiently large to ensure that the user is working at the maximum of his or her aerobic capacity, a processor for determining from said values of distance and time an aerobic capacity, and output means for outputting a measure of exercise level to the user based on the calculated aerobic capacity, wherein the aerobic capacity conforms to the relationship expressed as:
-
VO2max=a+bx+c(xˆ
2) wherein VO2max is the maximal oxygen consumption of a user, wherein a, b and c are non-zero constants, and wherein x is a measure of distance per unit time.

Abstract
A device for measuring the aerobic capacity of a subject, has an input for receiving a measurement of distance travelled in a given time. The time is chosen to be sufficiently large to ensure that the user is working at the maximum of his or her aerobic capacity. A processor determines from the values of distance and time an aerobic capacity, and a measure of exercise level is output to the user based on the calculated aerobic capacity. The calculated aerobic capacity conforms to the relationship expressed as V02max=a+bx+c(xˆ2) wherein V02max is the maximal oxygen consumption of a user; a, b and c are non-zero constants, and x is a measure of distance per unit time.
