A heart rate monitor device suitable for use in monitoring aerobic exercise training, automatically calculates a fitness parameter for a subject by monitoring the subject\s heart rate and pacing the subject through a submaximal exercise stress test protocol. A microprocessor in the device is fed data peculiar to the individual subject, and then generates pacing signals to produce audible tones or beeps. The stride frequency, or rate of the tones varies at intervals so that the subject can exercise by running at progressively faster speeds. At the point of exhaustion, or maximum heart rate, the subject\s maximal oxygen uptake capacity is calculated, based on the elapsed time, and is displayed as a fitness parameter. The subject\s exercise level is automatically monitored based on his or her exercise heart rate, maximum heart rate, and rest heart rate.

In a personal fitness level monitor system for monitoring fitness parameters of an animate subject as a function of heat rate during exercise training, of the type comprising heart beat sensor means worn on said animate subject to sense said subject\s heart beat; data entry means for entering selected data peculiar to said subject; display means for displaying said entered selected data and one or more fitness parameters calculated on the basis of said entered selected data and the detected heart beats of said subject; and microprocessor means for storing said entered data and calculations exercise heart rate HRE from said detected heart beats and calculating said one or more fitness parameters based on the entered data and heart rate data, said system including timing means for use in measuring the heart rate of the subject on the basis of said detected heart beats; and indicator means providing an indication to said subject of the level of training exercise; the improvement wherein said fitness parameters include a maximal oxygen uptake parameter VO2max as a fitness index; and said microprocessor means includes: (1) means for establishing an exercise protocol in which the subject exercises at a first relatively low effort level for a first period, and at progressively higher effort levels for corresponding successive periods, means for continuously measuring the heart rate in said microprocessor means based on said detected heart beat of said subject while the latter is exercising at each of said effort levels according to said protocol; (2) means for halting the exercise protocol when the exercise heart rate HRE of said subject reaches a maximum heart rate HRM predetermined from said selected data, and means for storing the maximum heart rate HRM and elapsed time T from the commencement of said exercise protocol until said maximum heart HRM rate is attained; (3) means for calculating and storing said fitness index according to a relationship VO2max=aT+b where a and b are experimentally derived coefficients; and (4) means for causing said display means to display the calculated fitness index VO2max.
