Here's what Joel Jamieson has to say about HICT.
This method is different from other forms of aerobic training in that it is both high intensity and relatively high volume. This unique characteristic is also why it (is) so effective. Whereas most aerobic training methods are either high intensity/low volume intervals, or high volume/low intensity continuous training, the high intensity continuous training method is high intensity based on resistance rather than speed and thus it allows for a higher volume of stimulus.
More specifically, a little like the tempo training I'm doing on Tuesdays, HICT helps by "increasing the aerobic abilities of your fast twitch fibers."
