HRM and calorie counts

I don't know if it's just how I put my settings in my HRM but they do not coincide with the calories on MFP. Anyone else notice this? I know I'm working out 'vigorously' because I'm at 85% (sometimes 90%) of my heart rate throughout most of the workout - I really try to push it each time, but the calories are just considerably lower on my HRM. I doubt an hour of biking is only burning 350 calories. Especially when I'm drenched with sweat and completely exhausted afterwards. Or maybe????

A HRM will be far more accurate then MFP estimates. Your heart rate is a direct correlation with effort done. It can also tell you when your over training if your HR stays high after you work out. 90% max heart rate sounds like to much unless your doing intervals.
Also MFP estimates don't take wind into account. Which is a huge deal on a bike.0 -
Whenever I use a machine at the gym that gives a calorie count, it is usually DOUBLE what my HRM says.
Same thing goes for what MFP estimates.
I was pretty disappointed about this at first.... I was thinking about calling Polar and seeing if my HRM was malfunctioning or something. But that is just hopeful thinking probably~0 -
I've heard frequently that MFP numbers run high. I would trust my HRM far more than the estimates provided by the site. Some exercises will show similarly, but others seem to be off a good deal.0
-
Definitely go with your HRM. I was disappointed too when I first got one and saw how much less I was burning than what MFP told me, but really, its much better to know the truth!0

My HRM is almost always pretty darn close to MFP, I don't know why that is...a lot of people say theirs is lower. Hmm. It's actually higher on the calorie loss than my treadmill says I burn.

I am the opposite, my HRM tells me almost double what mfp and the machines do. I have been told this is different for everyone, if your HRM is one that you can input your stats (height and weight) then go by your HRM. For instance, my workout buddy and I did the exact same class at the gym, our HRs were very close to one another and we are similar height and age, but she weighs 125 and I weigh 170. I burned double the calories that she did.0

Add me to the disappointed club! LOL - I just got a HRM too, and it is less than what the machine/MFP says - but I'm glad to know because I was eating back exercise calories that I hadn't burned - so now I rely solely on the HRM.0

I've noticed the same
It seems that my heart rate usually doesn't get terribly high during a 30-40 minute workout on the elliptical at the gym. It seemed that: My HRM calories burned << MFP calories burned < elliptical machine reading for calories burned.
I've found that when I wear my HRM for playing hockey, my calories burnt are much higher than I expected... up to 900 for two hockey games (games are 45 minutes, and I usually play 1/3-1/2 of the game.. but I guess my heart rate gets so high when I am playing, that I am still burning calories when I am resting during the game).0 -
I have a Polar FT7 with a chest strap. I entered all my info, height/weight, into it and went on a 90+ minute walk yesterday to the store. The HRM said I burned around 630 calories. I am 5'6" and between 255 and 260 lbs (depending on the day, time, etc). This seems really high. Most of the time I was in fat burn mode. IDK, I just hope I am not getting my calories burned overstated, because I eat them back, netting around 1300 a day.0

I always wear a HRM, the kind that straps around my chest. I don't trust the ones on the gym machines and the calories given from MFP are just estimates. I usually burn about 500 to 800 calories in an hour but I work very hard. If I burn 800 that means my heart rate is averaging around 170 which is a pretty intense average for an hour, but I can handle it cycling. But I can't handle it running, I average about 155 running. I am 36 yrs old and weight 146 lbs and may have a higher heart rate when I work out than some. Your calories do seem really low for your effort I would constantly check what your heart rate is when you are working out, sometimes it doesn't read right and then you won't get an accurate calories burned. Also are you using it right, check your manual, if you don't have one you can get the online usually.0

Trust your HRM (especially if you can set the VO2). It is the most accurate for each individual that uses it.
MFP is an estimate only, the machine at you gym can't tell how much effort you're putting in, so also an estimate.
You and I can do the exact same work out (and weigh the same), but do to the quality and effort put into the work out, have different calories burned~0 -
The only exercise where my HRM matches MFP is walking. Other than walking my HRM shows a lot lower calorie burn then what MFP estimates.0
-
yeah mine is usually half the machines
and biking isnt like sprinting
my heart rate is usually on like 180
and i burn about 400calories an hour0 -
Th HRM will be correct (unless you get it checked and it proven faulty) MFP and the machines in gym tend to well over estimate. You may just be fitter than you think, at 16 stone I would burn 750 - 800 cals in an hour on a crosstrainer, now I only burn around 400, its just because I am fitter than I used to be and not as over weight, frustrating as it is its the truth!!
Keep at it though, if you are losing and feeling fitter and better for it the numbers shouldnt matter too much x0 -
Funny reading people having experience with HRM's logging less than MFP... I have a Polar FT7 and use it whenever playing basketball (in a non-comp environment), walking, jogging and even when strength training and the read outs are always higher than what MFP estimates. At first I thought it was high but had a run with an FT80 and got near identical results so I'll always log my HRM data over MFP estimates or a gym equipment read out.0

Depends on the HRM. I have two: a Polar FT7 and a Timex. The Timex consistently shows about double the calories burned as my Polar. So I usually count what my Polar says, just to be on the conservative side, especially on days where I eat back my exercise calories....last thing I want to do is eat back more than what I really burned. But it sure is frustrating to see huge differences depending on where you look for calories burned. It'd be nice if the estimates were closer together, even though I know that yes - at the end of the day, they are just estimates.0
-
I just got my HRM and so far its coming below what MFP calculates not by much about 60 calories or so.0
-
I purchased a (Polar) HRM for exactly this reason, after reading on the forums here that it was the most accurate way to get the calorie count. What I'd like to know is why when I enter exactly the same information into the ellipticals at the gym as I have in my monitor, and when the monitor actually links to the elliptical, and when my heart rate is the same on the HRM and the elliptical readout, the calorie burn reading is so far off. My husband says its because the manufacturers want you to think you're burning a lot of calories. Anyone else have this happen?0

Same! I was a little disappointed when I got mine, but in the long run, it's a great tool because I know more accurately what I'm actually burning instead of it just being a crap shoot.
As for the elliptical burn. I get a hella! burn by doing it in HIIT. I do level 10-12, depending how I feel that day... I do a little warm up (3 minutes or so), and then I go just as fast as I can for 30 seconds. Then slow 30 seconds. Then fast 30 seconds. Then slow for 45 seconds. Then fast for 45 seconds. Slow for 45 seconds. Fast for 45 seconds. Slow for 1 minute. Fast for 1 minute. Slow for 1 minute. Fast for 1 minute. Slow for 1m 15s, Fast for 1m 15s, slow for 1m 15s, fast for 1m 15s, slow for 1m 30s, fast 1m 30s, slow 1m 30s, fast 1m 30s... 1m 45s the same, then up to 2m the same, then up to 2m 15s the same, then 2m 30s the same. Then I go back down. 2:15 intervals, 2:00 intervals, 1:45 intervals down to the 30 seconds. Then I just go a steady pace a few minutes to slow it all back down. This is the ONLY way I get over a 10 calorie/minute average on the elliptical anymore. I used to all the time...0 -
My HRM is always lower than MFP, just makes me work that much harder!0
-
HRM is way more accurate because it takes into your individual stats while MFP estimates are just that- generic estimates.0
-
I have a Polar FT4 and I just went swimming. My HRM says I burned 340 calories and when I entered the info into MFP it says I should have burned 820! That is a huge difference and I am happy to eat back what my HRM says I burned instead of eating 500 more calories. If you did that every day imagine how many extra calories you are eating in a week! I say go with your HRM0

On a average 60 minute workout on the treadmill very fast pace walking 7.2kph. My Polar FT7 usually records more cals burnt than the running machine. On average my HRM give me 652 cals burnt per hour against 612 on the running machine. I usually up it by doing plenty of arm movements ie punching/slapping. This must add to the cals that the treadmill doesn`t pick up.0
-
My HRM is usually less than MFP too, but only by like 20-30 cals or so.0
-
My HRM is about 100-150 cal burn difference than mfp, and its my hrm that is more cals burned than mfp....I trust my hrm more than MFP...Since i have been eating according to the cals burned to what my HRM says, i feel like i have more energy, better results with dropping my last 6/7lbs...as i didnt get a hrm until this last christmas. As long as your settings and info are programmed into your hrm correctly..i would def trust that as your best bet on getting the most reliable number for cals burned.0

just curious how you use your HRM while swimming??I have a Polar FT4 and I just went swimming. My HRM says I burned 340 calories and when I entered the info into MFP it says I should have burned 820! That is a huge difference and I am happy to eat back what my HRM says I burned instead of eating 500 more calories. If you did that every day imagine how many extra calories you are eating in a week!

sorry if this is a stupid question. -_-0 -

It is water resistant and has a chest strap so I don't have to push any buttons. Not a stupid question. When I went looking for a HRM I wanted one that was water resistant because I do a lot of swimming.0 -

awesome! Mine is water resistant (polar ft7), but the chest strap isn't, so it doesn't do much good...0 -

My chest strap is water resistant. I wonder why the polar ft7 is water resistant but the strap is not?!0
