I have aquired a HRM...It does have the chest strap etc but as far as I can tell it only records heart rate. I have checked and its accurate on the BPM. There are no instruction manuals online, its a basic model used by schools (my son was given it as new supplies were coming in) What I need to know is how (if there is a way) to work out calories burned from BPM...is there a formula without knowing my breath expiration readings etc?


Cheers in advance :drinker:

    would need to know make and model .... it may not be possible and - if it is a basic model as you say - it may literally just be an HRM ....

    DSX...no model number as far as I can see. I just thought there was a formula for calculating calories burned from resting heart rate/exercising heart rate/ weight/gender etc. Ah well, its useful to keep me working at a constant level

    My very expensive HRM (Garmin Forerunner 305) calculates calories burned only by distance! I'm riding my stationary bike and doing p90x so this does not help at all. I looked online and found this formula for calculating calories burned using gender, weight, average heart rate, and time. You just have to figure out a way to estimate your average HR. I hooked up my Forerunner 305 to the computer and it told me mine. Just plug and chug! Link provided below too.

    Formula

    The Journal of Sports Sciences provides a calorie expenditure formula for each gender.

    Men use the following formula: Calories Burned = [(Age x 0.2017) -- (Weight x 0.09036) + (Heart Rate x 0.6309) -- 55.0969] x Time / 4.184.

    Women use the following formula: Calories Burned = [(Age x 0.074) -- (Weight x 0.05741) + (Heart Rate x 0.4472) -- 20.4022] x Time / 4.184.
