don't get it. All this blah,blah,blah when we know it is the food...

my favorite part:

The most utilized protocol in past research has been the Wingate test which consists of 30 s of all-out sprint with a hard resistance [13]. Subjects typically perform the Wingate test 4 to 6 times separated by 4 min of recovery. This protocol amounts to 3 to 4 min of exercise per session with each session being typically performed 3 times a week for 2 to 6 weeks. Insight into the skeletal muscle adaptation to HIIE has mainly been achieved using this type of exercise [13]; however, as this protocol is extremely hard, subjects have to be highly motivated to tolerate the accompanying discomfiture

30 seconds all out with 4 mins of recovery? yes, please! try 30-30's, or some tabata, then let's talk about "discomfiture"

Or try some m-100's!

if there are only 4 minutes of recovery, it's not an all-out effort. it can't be.

thanks for posting as I feel fat and out of shape after a month of no weight bearing. Have you seen anything on the typical 8-rep Tabata cycle of 20 on 10off as far as it qualifying for HIIE--from this it seems like the ratio of work to rest is skewed in tabata, but it is also in total only 4 minutes vs 20 min

You could also argue that if the efforts are 30 seconds, then they can't be all-out efforts.

"All-out" must not refer to an absolute maximum, but a value relative to the effort and recovery times.

I still bet my 50 mile ride at low intensity burns more fat than one of these new fangled high intensity interval workouts.

But note the big emphasis here on duration of workout... takes me 3+ hours to do a lower speed 50 miler...

And even 30 minutes of low intensity likely does not include the cardiovascular or aerobic benefits that come with HIIT/HIIE/Tabata/etc.

Over the past 7 months, since I was injured when rear-ended, my physical therapist, personal trainer, and my own research have transformed my workouts, and, as a result, my health and conditioning dramatically for the better via a complete shift to HIIT and related exercise protocols. It is not only (primarily) the exercises themselves, but also the fact that I can complete the protocol in 15-20 minutes (or even less), so I'm exercising much more frequently and regularly.
