HRM Calories

JustBill

I've been using the Polar F7 for a couple of weeks now and I'm amazed at how many calories it tells me I've burned during a workout or a jog. It seems really high compared to what a treadmill tells me even though they both agree on my heart rate.

So my question for the forum - does the HRM take into account the calories that I'd be burning "at rest" if I were not working out at the time? In other words, do I need to subtract my "at rest" calories from the total on the HRM?

I don't subtract anything. Whatever my FT7 says I burned is what I log.

That would depend on how you have set your activity level on MFP. I am set as sedentary and I log whatever my HRM tells me. I log nothing else other than specific workouts. If however you log walking the dog, doing groceries, gardening and the like then you should most likely subtract what you would normally burn at rest.

i have a bit of an equation...

let's say MFP tells me i burned 366cals for 60 minutes of "general" aerobics. my polar FT4 says i burned 495cals for that same amount of time. i add the numbers together and divide by two. the resulting number of calories is what i will say i burned.

i am terrified of overestimating my calories burned through exercise, so i figure this way the margin of error is perhaps smaller. but, seriously, all of these "calculators" are based on averages and approximations and nothing can be 100% accurate ^_^;;;;
