Question: how to calculate calories burned heart rate?
Answer: The Journal of Sports Sciences provides a formula for this calculation: Calories Burned = [(Age x 0.074) + (Heart Rate x 0.4472) -- (Weight x 0.05741) -- 20.4022] x Time / 4.184. Assume for this example that you're 32 years of age, your average heart rate during the exercise was 127 bpm, your weight is 143 lb.
