How accurate are the calorie counters on treadmills?

RoyBeck

Anyone know if they are pretty much spot on?

I don't know if they are spot on or not because I don't have a HRM. But I use those readings all the time because they are a little bit lower or very close to MFP.

As you can see by my ticker, I reached my goal. Most people in this database will tell you to get a HRM for serious cardio exercises, so it is up to you.

Good luck!

Not accurate at all IMHO. Get a HRM for a more accurate reading.

HRMs aren't very good at estimating calorie burns.

Anyway, if you programmed your weight on the treadmill it should be pretty accurate.

my finding would say not remotely accurate... my HRM puts my calories and 1/3 less...

now the spinning bikes seem to give me a much more accurate number... no idea why... they are both made by the same company...

I honestly don't really trust them; they typically seem to over-estimate grossly from most of the more reputable calorie burn calculators. Now that I've got a heart rate monitor, that's pretty much verified that, in my experience, most of them are off by a good ~25-30%. I think in general, most people burn a little over 100 calories per mile when running. I found the following calculation which actually seems to line up pretty well with what my heart rate monitor comes up with:

Running calories per mile
weight (lbs) x 0.75

Walking calories per mile
weight (lbs) x 0.63

Highly unlikely - they will give an average for your age/sex/weight.
They won't know your fitness, your running style etc. etc.

Unless you are in a laboratory environment with controlled oxygen and temperature any method is just an estimate.

The big advantage of HRMs is consistency, you still won't know if the calories are accurate, they count heartbeats not calories...

Yeah, but individual calorie burn doesn't really vary much for a given height and weight. The energy it takes to move a 150-lb body a mile at 6 mph is what it is.

HRMs aren't even consistent, as your VO2max changes dramatically over time.
