Let's pretend, for a second, that I'm stupid...

I've been wearing my HRM all day, with the hopes of findong out how many calories I burn at work. Well...it hasn't worked out that great, seeing as how I've been in and out of a vehicle most of the day, and for some reason my HRM won't work while driving. Also, I did turn it off if I was sitting for longer than 5-10 minutes.

So here's my question, it's been running for 8hours and 44 minutes, and says I've burned 414 calories. My BMR is 1690. Shouldn't my calories burned for the day be somewhere around there? Or even more since I'm up running around and doing things? Or am I completely off my rocker? My heart rate definitely rarely made it up to a "good" range, but mind you, this was an experiment.

I'm just a little lost here :-S

That seems WAY off....I have one that you wear all day and it's never that low....not even close.

annie_p

Like I said, there were times when it was...malfunctioning, or I turned it off, but never for very long. I mean, probably all together...since I was just sitting, less than 100 calories.

The way I've heard it is that HRMs are not meant to be worn all day, they're only for intended exercise when your heart rate is elevated. If your heart rate didn't increase much today, it's not going to register a burn.

just kidding....you left yourself open for that one....


HRMs are NOT meant to be worn all day, it just will NOT work.

You would need a BodyBugg or BodyMediaFit for that.

HRMs work for times of elevated heart rates ONLY.

HRM's don't work that way, you'd need a bodybugg to wear all day to figure that out. Lots of threads on this very topic in the archives, might check the Search feature and you'll likely see the exact answer of 'why' it didn't work on one of the many threads comparing a bodybugg vs. HRM's.

ETA: Oops, looks like Robin got that one for ya:flowerforyou: Too funny, so many of us hit the board at the exact same time 7:10pm all with the same response.:laugh:

Pretending....




It's a good question though. Unfortunately, I believe the only equipment that can monitor you for 24 hours is a body bug. HRM only work for short periods of time and really only work accurate during aneorobic workouts IIRC.

Now if you had a body bug and it told you, that your BMR was 1500 calories and you burned 500 calories throughout the day, you would burn 2000 calories total. That means in order to lose weight, you need to eat 1500 (to lose 1 lbs a week).

That's not how heart rate monitors work.

HRMs are designed for elevated steady state cardio exercise.

If you want to find out how many calories you're burning at work, you'll have to invest in something like a BodyMediaFit.

414 sounds extremely low. I would consider a different HRM. I use a Polar RS200 and find that it is very accurate and dependable.

HRMs are not meant to be used this way and will not be accurate. The calculation they use is based on HR and oxygen uptake during constant physical activity; this is why they're not particularly accurate during strength training, where HR doesn't correlate to oxygen uptake in the same way. Your HRM will not give you an accurate, or even close, estimate of calorie expenditure when you're not engaged in cardiovascular exercise.

A BodyFit or BodyBugg or whatever they're called would be better for this experiment.

mine doesnt work while driving either for some reason. either that or i get really stressed when i drive because i seem to have a heart rate of 220.

LOL that was my intention actually.

As I said, just an experiment. And obviously my hypothesis was incorrect in thinking I would "burn" the 1690 of my BMR.

LOL Mine jumped way up a few times too...and then it would register at 0.

It's pretty acurate when I'm actually exercising. As I said, only an experiment.

I'm just curious on what kind of heart rate monitor you can turn off.

Did you just get it because I think it's a right of passage that once you get a hrm, you try to see how many calories you burn for 24 hours. And I only think that because that's what I did.

I can't turn mine off without taking out the batteries...at least not that I've found. And I've had it for quite a while(almost a year probably).

Dont forget, your BMR is the amount you would burn over a 24 hour period. if you multiply your 8hr burn by 3, it is a lot closer...

glassyo

Oh! Because you'd said you turned it off for like 15 minutes when you were just sitting so I had this vision of a switch or something.

I meant I stopped the timer.

You're right, and it is...but it's still a ways off. Oh well, that's why I experiment!

my bmr is around 1800

i'm 5'2" 120 lbs

dustyhockeymom

A HRM isn't designed to be worn like that. It is only going to give you an accurate calorie burn if your heartrate is elevated for a period of time. If you want to wear something all day to get your calorie burn you need a bodybugg or something similar.
