HRM Reading seems wrong. Help?

I just got off my treadmill, from a 30 minute walk/jogging, alternating between about 3.0 mph and 4.0 mph every minute or so. at the end of this workout my HRM read "523" for calories burnt. I didnt drop out of the 'zone' and I am 243 pounds. Does this seem right to anybody? I've heard that bigger people burn calories faster but I really doubt this is right seeing how my Treadmills built in thing(which is just an estimate cause you cannot enter in your details) said 230 calories burnt.
So confused! If i did burn this much, awesome but seriously doubt it.

your hrm is much more accurate than the treadmill. id go with the hrm...0

That seems CRAZY high though! Like I see people on my list doing insane workouts that dont get around there.0
-
That could very well be right. I'm 73kg and can burn between 300/350 calories in 30 minutes on the treadmill walking/running.0

If your hrm asked for your age, weight, sex and a resting heart rate then it should be pretty accurate. Personally I believe that there is no CORRECT device to measure calories burned. Everyone is different. But like I said if it calls for the above then it should be as close to most accurate as there can be.0

Unless your HR was in the 160s or higher, I'd say that number is very high.0
-
I don't know about the HRM, but when in doubt I go with the lower number and figure I can only be ahead! Your weight loss should give you an idea of which is correct for future reference.0

My HRM is sometimes higher than treadmill readings when I run but very close when I cycle. If there is a large discrepancy (and sometimes it is like a 200cal difference) I go by the smaller calories burnt to be conservative and on the safe side.0

I took an hr walk today and burned 569 cals my avg HR was 128. I bet your HRM isn't off. Plus men burn more then women. When my husband goes on a walk with me he'll burn at least 100 more then me, partially becuz he's taller & heavier. I have also noticed that when I run I'll burn twice as many calories as doing another cardio/weight type work out. If your skeptical either do something else that you already know the calories or log it low. Never hurts to be under!0

I am really kinda hoping this is right, because it was 70 bucks, and like... if I was gonna just get this, to find out it's a bit off, and use a lower number i'd save the money :S
Is there some kinda equation I can do or something to figure this out? I AM a heavy guy and I do get tired out doing the exercise come the end of it but 500 is so high compared to the treadmills reading(which i know is just a general thing.0 -
It's best to just see if you get the same numbers on a similar workout. That tells you it is either right or consistently off.0
-
Alright, I'll have to try somethin else soon. Would biking be drastically different in comparison to get a different number or should I try a bodyweight circuit training type thing ?0
-
I hear you, have totally the opposite worry myself. I workout hard doing high energy dvd workouts and struggle to get over 200 in a 40 min session. Luckily I never eat all my exercise cals.0

It's just worrysome/frustrating to think this could be inaccurate. It's not about the money, if it's wrong, I can take it back and get the moolah no problem at all, this is just kind of bothering me now.0

you can also try this website for estimating calorie burn:
http://www.triathlontrainingblog.com/calculators/calories-burned-calculator-based-on-average-heart-rate/
just use the average heart rate that you got on your HRM and the number of minutes for that average. If you don't know your V02 max, plug in 35 --DON'T LEAVE IT BLANK; IT WILL OVERESTIMATE.
Bigger people burn more calories than smaller people at the same activity. As your size decreases and your fitness increases, you will burn fewer calories during the same activity.
However, as you become more fit, you will have more lean muscle mass, and your lean muscle mass will burn calories for you even while you sleep, as long as you keep it fueled with enough good calories.

So basically my hrm is about 400 calories off according to that site V___________________V
This is really freaking annoying me right now.0 -
I had the same question. My HRM says I burn 800+ calories on a 45 minute, fairly intense P90X cardio workout plus my max heart rate gets way higher then the "220 - age" estimates say. I'm only in the zone for about 5 minutes in a 45 minute workout the rest of the time I am way over but I feel ok and I am not pushing it that hard. I have since turned off my alarm on my HRM and just push my workouts until I feel uncomfortable and then back off a little. I usually only log half of the calories my HRM indicates in MFP and even then I don't eat those calories back. Then again, I'm about 30 LBS from my target so I have plenty of fat stores.0

I thought maybe there was a setting off or something, your HRM sounds exactly like how mine would read a 45 minute workout, Scott. It's weird!0
-
what kind of hrm do you have??? i honestly think your hrm is right thats about 100 more then i would burn doing your workout so i think u r good but if u have an hrm with a starp and your heart rate was in the zone i think ur hrm is right on0

i have a sportline SX. it has a strap and everything, and I even moistened the strap a bit to make sure that the electrodes would work and all that.0
