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(x^2) 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.

Abstract: An exercise monitoring apparatus comprising a training shoe 10 including a sensor 12 for generating a signal which varies according to the activity of the foot. A microcontroller 18 analyses the sensor signal to detect each footfall, and a radio transmitter 20 transmits data packets related to the number of footfalls detected over time. A wrist unit 24 receives the data and processes it to calculate a quantity based upon the received data, and includes a display 34 for displaying the calculated quantity.
