HRM accurate?

Levedi

Hi folks - I just came back from an hour hike using my new HRM. It's a New Balance N4 for women with a chest strap. According to the HRM I kept my HR in the intense zone the whole time and burned 707 calories. I'm skeptical. I can believe my HR was up there - that felt about right but I'm a little hesitant to think I really burned that many calories. I input hiking, cross country in the MFP calculator and it came back with 555 calories, which is still pretty high.

What number would you go with? Should I trust this HRM's calorie count?

I would go with the HRM. MFP is always way off.

As long as you know that the HRM is set for you, with the target heart rate etc is correct, then I'd go with the HRM.

i did the same thing yesterday, and yep, my HRM said it was up there. .. I used it for my part time job today(working at a boarding kennel), and a decent clip walk around the non flat front field in 90 mins, my HRM Monitor said i burned something like 780 calories?? I put in 500 just because I couldnt' believe that I did that much

HRM. It knows what your actual heart rate was the whole time. MFP is just an estimate.

I bought a hrm also - and have a hard time believing my calories - but why have one if you are not going to use it - so I just used the numbers:flowerforyou:

trust the HRM as long as you input your weight correctly into it. MFP tells me I burn 450cals and the HRM says 702. I know it is a big difference but that is why we buy the HRM's/ for accuracy.

Another thing to consider is the calories that you would have burned if you slept for the amount of time you exercised. I don't usually worry about it if I'm only working for 30 min or so, but for anything over an hour I subtract it out.

To figure your hourly burn, find your maintenance calories (if you're set to lose 1 lb per week, it's your daily allowance, plus 500) and then divide by 24.

Just something to consider!
