How are Calories Calculated on the ELEMNT and Wahoo Fitness App?

Calories on all ELEMNT GPS Bike Computers and the Wahoo Fitness app are calculated using an algorithm.*  This calculation is made once per second and is different for men and women according to the following equations:

 

Men:

calorieBurnRate = abs(((0.6309 * newHeartrate) + (0.09036 * weightInPounds) + (0.2017 * userAge) - 55.0969) / 4.184)

 

 

Women:

calorieBurnRate = abs(((0.4472 * newHeartrate) - (0.05741 * weightInPounds) + (0.074 * userAge) - 20.4022) / 4.184)

 

 

 

Additionally, when BPM goes below 65% of max heart rate, Basal Metabolic Rate (BMR) is used in lieu of the algorithm, calculated as follows:

 

Men:

BMR = 66 + (13.7 * weightKg) + (5 * heightCm) - (6.8 * ageYears)

 

 

Women:

BMR = 655 + (9.6 * weightKg) + (1.8 * heightCm) - (4.7 * ageYears)
