HIIT (high intensity interval training)

Does anyone know how many calories 15 minutes of HIIT would burn?

    It's variable dependent upon the exercise performed, the intensity, your weight and your fitness level. No one can give you a definitive answer on this.

    How many of those 15 minutes were actually high intensity and how much was rest?

    In any case, less than a moderate workout would have burned, even factoring in the "afterburn."

    Based on the info you gave us, I will say anywhere between 25 and 250...

    See http://community.myfitnesspal.com/en/discussion/comment/36682039#Comment_36682039. Calculation based on a real HIIT regimen (as opposed to marketing) at duration of eighteen minutes. Just reduce the warm up period to seven minutes and do a Functional Threshold Power test to get your ballpark VO2Max wattage. If cycling isn't your cup of tea, your choice are rowing & running in a lab to get the parameter(s) needed.

    Try using a heart rate monitor. Also you can get a rough estimate using a google search. There are algorithms that use your age, weight, time exercised etc to estimate your calorie burn.

    An HRM isn't really designed to track interval type training.

    The lag time in heart rate response to a change in exertion - 15 to 30 sec lag with 2 to 3 min to stabilize at the new level of exertion. By the time your heart rate catches up your session will be a quarter to half over depending on the regimen. Data derived from it is as good as useless.

    HRM is applicable only for steady state activities up to your threshold for about two hours. And MANY factors will influence it besides the activity. It's a rough guide.
