Thread: HIIT-increases heart rate throughout day?

Yes, it will do that.

However, if you notice a significant increase in your resting HR on a day off, usually taken upon awakening, you are overreaching which can be remedied by a day or 2 off. If you notice a large difference in morning HR, you are overtraining, which would require a little more time off. Of course, you would expect to notice an increase in morning HR if you did HIIT later in the evening the day before.

Ive read from a few sources that your metabolism remains, "reved up" for much longer post excercise than after doing regular cardio. I would assume it wouldnt take too long for your heart rate to return to normal.

Oh nevermind.

I would really like to hear more about HIIT keeping someones heart rate up for the rest of the day...

Well thats kinda what i was thinkin at first.

It's only a couple beats, not anything you would really notice. Even if you took a 15 second pulse you wouldn't notice it.

the purpose of HIIT cardio is not to elevate the resting heart rate but to increase the resting metabolic rate, there is a big difference. bascially HIIT cardio increases your V02Max which increases excess post-exercise oxygen consumption (EPOC) which is commonly referred to as the "afterburn" effect.
