Day 61: Heart Rate vs. Calorie Burn
Maybe it’s because the heart rate monitor’s calorie counter is off! Stupid HR monitor!
[We are in a fight!]
Women:
I
entered my info into this calculator, and the reading said 307. If I had been entering 400+ calories into
MFP, I will have been eating at least 100 more calories a day! That’s 700 a week! Not good!
Now
that I have almost all of the Girl Scout cookies out of my house, I think I can
get back on track and start using my new handy dandy calculator [ok, too much
Blue’s Clues]. Woohoo!
I’m
going to try using the calculated calorie burn and see if that makes a
difference. I only need 12 more pounds
to get back to pre-baby weight, so I’ve got to step it up!! Bikini season is creeping up on us!
Yikes!
How accurate are heart rate monitors at telling you how many
calories you’ve burned?
After running on the treadmill this morning, I looked at my
heart rate monitor to see how many calories I burned. It said I burned 456 for running on the treadmill
for about 30 minutes. I started thinking
about it, and that seems a little high for just running for 30 min. When I entered it into My Fitness Pal [AKA: favorite app on
the planet!], it told me 354 calories. Which
one is correct? What if neither is
accurate?! Is this why I can’t get over
my plateau? Have I been eating too many
calories???!!! EEEEECCCKKKKKK!!!!!

Ok, I guess I shouldn’t be hard on the little guy since he
is really just made to monitor your heart rate [thus why it is called a heart
rate monitor and not a calorie burn counter, duh]. From now on, I am going to just have to
calculate my calories burned. How do you
do that? Funny you should ask!
How to calculate your calories burned using your age, weight, average
heart rate, and time exercised: [From the Journal of Sports Sciences]
Men:
Calories
Burned = [(Age x 0.2017) -- (Weight x 0.09036) + (Heart Rate x 0.6309) --
55.0969] x Time / 4.184.
Calories
Burned = [(Age x 0.074) -- (Weight x 0.05741) + (Heart Rate x 0.4472) --
20.4022] x Time / 4.184.
For those of us who are not mathematicians or engineers, here is an automatic calculator…much easier!!

Well, this worked in my advantage!! My heart rate monitor is way wrong in the opposite direction!! Now, do I invest in new heart rate monitor or calculate each time:). Choices, choices!!
ReplyDeleteWow! That's awesome!! I would probably just make sure it is calculating your heart rate correctly, and keep it for that :) I guess we just can't count on them to be accurate for calories burned. Mine was off by double this am! Yikes!
