does anyone know how to calculate how many calories are burned when doing high intensity interval training (HIIT)? I've been working working for about 30 minutes with my trainer doing HIIT and I've read you can burn about 1000 calories n hr doing it, is there a way to correctly figure how many calories u actually burn!?

You will need to get a heart rate monitor preferably one with a chest strap this is the most accurate way to find how many calories you are burning.

What I did is added it in two parts, the amount of time I sprinted and the time I fast walked.

Well You may want to invest in a HR monitor Like Polar with a chest strap. But every one is different. HIITs are not aways ment to be done for long periods of time but shorter with more intensity. I average about 250-300 calories in 30min when I and doing HIITs but again it depends on the Kind of HIITs your doing.

The Polar FT4 is the muts nuts. This will give you everything you want at a reasonable price.

If you're like me and you're too cheap to buy a heart monitor wink, take your pulse when you're in recovery, and again during your hardest phase, and figure out the average.

The following equation from the Journal of Sports Sciences calculates the calorie expenditure for women:
Calories = [(0.074 x Age) + (0.4472 x Heart Rate) -- (0.05741 x Weight) -- 20.4022] x Time / 4.184.
(weight is in pounds and time is in minutes)

(From http://www.livestrong.com/article/228774-calories-burned-from-high-intensity-interval-training/#ixzz24fAqabqr)

I used this formula and calculated that for my high-intensity interval jog for 30 minutes burns 400 calories, which sounds just about right to me. Hope that helps!

Im also trying to find the answer for this, If you look at circuit training which is a little similar you can lose about 800 calories in 40 minutes! But the thing with Hiit is not the calories you burn during the session but your body carrys on burning calories for 48 hours after Hiit! so its so hard to accuratly measure the calories burnt. i would guess about 800 though as long as you have really pushed yourself to breaking point!
My instructor always says unless you puke faint or die...keep going!

Before my hrm if I used a treadmill or eliptical I log my active rest and sprint separatley. 10 mins level 10, 10 mins at level 5.
Remember one of the benefits of HIIT is that you burn more calories during the next 12-48hrs depending on intensity of the workout.
I read somewhere that the maximum number of calories from afterburn effect is 15% of the workout calories burned. Don't remember where I read it or even if its true.

Nikkinz is correct! Hiit has more of an effect after it is done than hike it is being performed. Not only does it turn you body into a fat burning machine for sometimes up to 48 hours, it also increase high levels while minimizing cortisol levels unlike low intensity cardio. It is the best. But start with a 1:3 ratio if you have never done it before! Hope this helps

I think it's about 250-300 calories per half hour. Personally, when logging HIIT into MyFitnessPal (since technically you can't), I log it under 'Jumping Jacks, Vigorous' and since I usually do at least 2 or 3 minutes of vigorous jumping jacks in my HIIT workouts I feel like it's pretty accurate. For example, today I did 12 minutes HIIT and logged it in under that and it said I burnt 102 calories (I'm 62KG).

I thought the whole principal of doing HIIT as opposed to regular cardio is, you continue to burn fat and calories even after you get off the machine so basically you'll never know. Essentially, when you do high-intensity interval training (HIIT), your body and metabolism function at a higher rate of burned calories for hours and hours afterwards. Check out this article.
