Actual calories burned - help!

Hey MFP Hivemind!

I'm taking a kickboxing class. It's a solid hour of kicking, punching, cardio, and circuits (like burpees, abs, deadlifts, Jacobs ladder type stuff). I sweat the entire class.

I plug an hour into MFP and it spits out 915 calories burned. I think that's absurd. I'm not looking for the exact number here, but would be a good ballpark figure for a 200 lb 5, 7" female for something like this?

Do you know what your resting heart rate is? Do you know how long out of that time your HR is peak mode? What your average HR is? You can at least do a crude estimate, using those numbers. Shape Sense has some calculators you can use to at least see if the numbers are reasonable.

At first glance, the number looks like it might be high, but not absurd. Maybe 600-750 or so...

I don't think that the number is that high. I would maybe try a few different calories burned calculators and get some kind of average from them

Impossible to say without HR and intensity. Fitbit would aid with the HR and give a rough guide , isnt gospel on cal expenditure

I agree that number sounds too high, even at your current body size.

I would say most people who are training near max intensity burn between 200 and 350 calories every 30 minutes. Any more than this and it sounds fishy.

Thank you everyone! I've been manually editing it to 300 calories when I log it. I don't know my resting HR and don't have a Fitbit. But I know how to check my pulse so lll try to do that periodically as an experiment. Thanks for your responses!
I had no idea that I could burn 600 calories in an hour! Wow!

I mean its definitely possible. But it all depends on your intensity, for you, you've probably got to be killing it the entire hour, dripping sweat, out of breath, heart rate high, nearly the entire time. Definitely possible though

Do you know how the intensity compares with running for you? (Running calories can be estimated pretty well, and might give you a ballpark idea).

300 sounds reasonable to me. If you find you're losing too quickly you can always bump it up.

My guess is 200cal per 30 mins.

I got 380 per hour for my karate class (garmin), but I'm dubious as I'd equate about 100 to running a mile. So 3.8 miles. I suppose it maybe on the low side?? That's a brisk walking pace 3.8 miles in an hour (for my little legs).

At times, it's just as intense as running 6.0 on a treadmill, but it's definitely not that intense during the entire class. Only during the latter half of the high impact aerobic exercises do I feel like that. My breath and heart rate bounces around a lot because we switch back and forth between super intense and just, I don't know, regular intense, lol! My heart rate is definitely up for most of the class, but not in a "hold on while
I barf" level, if that makes sense.

You could try breaking it down into a few runs/jogs/walks of estimated mileage and speed, total, and see what ballpark number it gives).

300 sounds too low for an hour of constant exertion for a person who weighs 200 pounds. It's got to be at least 500. (Though I agree that 900 sounds too high.)

Calorie burns are strongly dependent on your size. So, when you read that somebody who weighs 120 pounds burns X calories doing something, realize that you will burn a lot more. For now, that's the good news. The bad news is that, as you get smaller, your burns drop. But, on the plus side, you're getting smaller.

I tend to use my husband and I as a good example since he weighs 80 pounds more than me and is 9 inches taller. Yesterday, we did basically the same stuff (which included a lot of physical activity). I burned about 3000 calories for the whole day (including BMR). He burned about 4500.

I play with my calorie burns with trial and error when i don't know the exact burn. I would start with saying that burned 600 calories and your and see how you feel after 6 weeks of logging that.
