HRM and Calories Burned

Prefessa

Yup....I think this is a good idea.....I also would get up one morning, before you had your coffee or breakfast, and wear it while clicking the remote. You burn more calories "At rest" then you do sleeping, you will burn a tad more....will also giver you a true assessment of the BMR.

So lets say you wear it to bed and sleep 8 hrs burn 800 cals.....but watching TV awake 1 hr you burn 115, so yor BMR is (115 x 16) plus 800.

I am not a big fan of canned formulas...like McKardle-Ketch or Harris-Bennedict....too many variables that can go on with your own body. I like the McKardle Formula the best....It takes into account LBM (I took his class when I was an Undergrad at CUNY.)

If those formulas were dead on, the folks in the Biggest Looser would be wearing 300 dollar BodyBuggs 24/7. I am willing to bet you will see a 30% discrepancy in BMR in those folks after they loose all that weight if you use formulas due to Adaptive Thermogenesis, and to some degree a shift in thyroid hormones. There was a paper published in J, Clinical Obesity in 2008 that states that while the BMR doesn't change much with weight loss, calorie ex[penditure with exercise drops with every loss of bodyweight of 10% or more. This was identical for healthy atheletes as well as ordinary folks, and is due to Leptin Downregulation.

Kinda makes sense....I mean guys like Lance Armstrong cycle 20,000 miles a year. If you think of the amount of calories typically estimated for intense cycling....he would have to eat constantly or dissapear.

I think my max heart rate was around 190 (yikes, I know) and low was around 120 or so (during warm up and cool down)? Average was around 165 I believe. I would need to double check those numbers once I get home.

if your average HR was 165 you would be hitting well over 1800 calories in that amount of time. somethings not right, you will have to figure it out. according to my HR if i am at 155ish for heart rate i burn 20 calories per minute. so at bare minimum you would be burning 1600 calories in that time, so please check it, let me know what yours comes in at, mine could be wrong also.

That's my average, too. Around 155-165.
