BMR and RMR

FaerieCae

I know this is probably going to sound incredibly blonde, but are BMR and RMR the same things?

Bump. It's my understanding that they're closely related, but not exactly the same thing. I'd like to learn about the difference, because I'm planning to have my RMR measured this week.

I've never heard of RMR till just now.

"BMR is measured under very restrictive circumstances when a person is awake. An accurate BMR measurement requires that the person's sympathetic nervous system not be stimulated, a condition which requires complete rest. A more common and closely related measurement, used under less strict conditions, is resting metabolic rate (RMR)"

Basically, one is just a more stringent test.

Athena,

Make *sure* you get your RMR tested under ideal conditions. 20 minutes of being purely still, no distractions, preferrably lying down and with a mask that doesn't allow leaks. Many of the RMR machines at gyms are incredibly inaccurate. Do a google search and you'll see folks - even gym employees - saying that they've done it twice in a week with up to a 600 kcal difference.

I had mine done and was so patently off-base, that I was pissed that I paid $50 for the test.

RMR is essentially a loosely-done test that is said to be closely related, but I have my doubts. Most places do not allow you to do it under optimal conditions. BMR tests require complete rest and stillness for a reason.

Ploogy! It's good to see you! I was going to have it done hydrostatically, which I've read is supposed to have a 1% margin of error. In the video link for the place that does it, the person wasn't wearing a mask, just holding her breath. Was the one you did something like Bod Pod?

Thanks for posting this. I read the linked page, and it doesn't sound like anyone would be able to do the BMR testing on me with the requirements for an accurate reading. I can't do a solid 8 hours of sleep without general anesthetic.

Thanks for the link, very informative, chur!
