Walking/running heart rate monitoring system
First Claim
1. A process of using a sub-unit of a heart rate monitor to plan and monitor progress in achieving physical fitness through walking comprising:
- inputting signals from a heart rate monitor to a sub-unit, the signals representing current heart rate, average heart rate, and total elapsed time;
inputting to the sub-unit a user'"'"'s age, weight, walking speed and current heart rate from a plurality of walking tests;
calculating a rate of calories burned per pound of body weight for each of the plurality of walking tests using a formula as follows;
rate per pound=A+BV+CV2 +KDV3,where A=0.0195, B=-0.00436, C=0.00245, and D=0.000801 (W/154)0.425 /W, where W=Weight (lbs), K=0 forTreadmill and K=1 for Outdoors and V=velocity of the user in miles per hour;
calculating a rate of calories burned per minute by multiplying the rate per pound by the user'"'"'s weight; and
outputting the values calculated.

Abstract
A process of using a heart rate monitor to construct a user'"'"'s personal heart rate curve, and using the heart rate curve to forecast the user'"'"'s personal caloric expenditure on the basis of the user'"'"'s heart rate while walking or running. A sub-unit installed within or otherwise connected to the electronic circuitry of a conventional heart rate monitor operates under control of a microprocessor. The sub-unit receives exogenous inputs by the user for conducting various calculations from a plurality of test data which is stored in memory by the user. The sub-unit utilizes the test data to calculate a rate of calories burned per pound for each test exercise, where the calculation is performed using a pre-programmed formula which differs according to the form of exercise. Next the sub-unit calculates a rate of calories burned per minute for each test exercise by multiplying the user'"'"'s weight by the previously calculate rate per pound. Finally, the sub-until applies a least squares linear regression algorithm for measuring calories per minute against heartbeats per minute for the plurality of test exercises, thereby producing a user'"'"'s heart rate curve for a particular form of exercise. During later exercise, output signals from the heart rate monitor regarding current heart rate, average heart rate, and the total elapsed time during exercise are used to calculate and output the current calories per minute expenditure, average calories per minute expenditure, and total calories expended for each exercise session.
