HRM Calorie Burned Question

titletown

Hey all, here's a question that's been bugging me for a bit.

OK, let's say my HRM tells me that I burned 500 calories in an hour workout...

Does that include the normal BMR calories and should I subtract an hours worth of my normal daily BMR burn from that total before I add it into an exercise here?

In my case, MFP tells me that my BMR is 1910. If I divide that by 24, that's about 80 calories an hour, so do I log the entire 500 from my HRM for my workout, or subtract the 80 from that total and log just 420?

Technically the calories you burn in an hour doing exercise include your BMR calories. So using your example you would log only 420 since 80 of the 500 was just BMR calories. But it's really small potatoes in the grand scheme of things.

Some people subtract it . Personally I can't be bothered.

If you count the calories burned at the end of your exercise. Example 500 But your wondering if the BMR of 80 calories should be subtracted to log 420 calories for exercise.

Try this. (assuming you are wearing a HRM)
Next time you stop your exercise, and record the number. Take a look at how long it takes to burn those 80 calories while "cooling down", which will be less than an hour.
ie, exercise plus cool down = 580 . Now you still want to take away the 80 BMR calories?

They just cancel each other out IMO.

interesting. i think i will take off my bmr calories anyway to be on the safe side as i dont know how accurate my hrm is.

Excellent point, hadn't thought of that.

My best logical guess would be that you log the entire amount from your HRM. The only reason I say this is because everything else here is set up to be "dummy proof", and 99% of people would never think to do the kind of math you're talking about. It never even occurred to me to do such a thing, but I understand why you're asking, now that you asked.
