How to Calculate Calories Burned Based on Heart Rate
A calorie is a unit of energy used specifically to measure the chemical energy in food. Your average heart rate can be used to estimate the number of calories you burn during an exercise session. This is a common goal for a weight loss plan since you will want to know your total calorie expenditure. The calorie expenditure is more accurate when you know your V02 max value.

Obtain your VO2 max value. This is a measure of your oxygen consumption rate while exercising at maximum effort. An accurate measurement of your VO2 max requires testing at a sports medicine facility but you can also estimate your VO2 with several methods such as the Cooper test. This test requires you to run as far as possible in 12 minutes. You may then estimate your V02 max as (d -- 505)/45 where d is the distance you ran in 12 minutes.

Calculate your calorie expenditure if you're male and don't know your VO2 value. This is given by the equation C = (-55.0969 + 0.6309 x hr + 0.1988 x weight + 0.2017 x age) x time / 4.184. C is the calories burned, hr is your average heart rate in beats per minute, weight is your weight in kilograms, age is your age in years and time is the time spent exercising in minutes.

Determine your calorie expenditure if you're female and don't know your VO2 value. This is given by the equation C = (-20.4022 + 0.4472 x hr - 0.1263 x weight + 0.074 x age) x time / 4.184.

Estimate your calorie expenditure if you're male and know your VO2 value. This is given by the equation C = (-59.3954 + (-36.3781 + 0.271 x age + 0.394 x weight + 0.404 x VO2 max + 0.634 x HR)) x time / 4.184 where VO2 max is measured in liters per minute.

Estimate your calorie expenditure if you're female and know your VO2 value. This is given by the equation C omen: C/min = (-59.3954 + (0.274 x age + 0.103 x weight + 0.380 x VO2max + 0.450 x HR)) x time / 4.184.
