# Heart Rate Based Calorie Burn Calculator for Unknown VO_{2}max

Heart rate monitor is used to determine how many calories you burn during exercise. The monitor gets the information about your heart rate using unknown VO_{2}max mathematical formula. VO_{2}max is the measure of oxygen consumption of body while exercising. The speed of the heartbeat measured by the number of contractions of the heart per minute (bpm) is the heart rate. Use online Heart Rate Based Calorie Burn calculator to find calorie burned for both male and female.

#### Formula:

**For Male,**
Calorie Burned = ((-55.0969 + (0.6309 x HR) + (0.1988 x W) + (0.2017 x A)) / 4.184) x 60 x T

**For Female,**
Calorie Burned = ((-20.4022 + (0.4472 x HR) + (0.1263 x W) + (0.074 x A)) / 4.184) x 60 x T

**Where,**
HR = Heart Rate
W = Weight in kilograms
A = Age
T = Exercise duration time in hours

#### Example

**A 45 aged man with 78 Kgs has average heart beat of 165 beat/minute with activity duration of 6 hrs. **

Calorie Burned = ((-55.0969 + (0.6309 x 165) + (0.1988 x 78) + (0.2017 x 45)) / 4.184) x 60 x 6

= (-55.0969 + 104.0985 + 15.5064 + 9.0765 / 4.184) x 60 x 6

= (73.5845 / 4.184)

= 17.587117591 x 60 x 6

= 6331.36233276 calories.

Heart Rate Based Calorie Burn is based on average heart rate for unknown VO_{2}max. It can vary according to the body's physical needs. It estimates how many calories burnt per minute for a person with age, weight and/or other factors burns at that heart rate.
