The net effect is, you know, this high-intense interval training, is getting that glucose out of your bloodstream and bringing it to your muscle where you want it ... People that even do high-intensity interval training before they're sleep-deprived, they do it after they're sleep-deprived, doesn't matter, if you're doing it within a 48-hour window or so of getting less sleep, what's happening is your glucose regulation resets, right? Because you're causing that stress on your muscle to make more glucose transporters, and so glucose gets taken in better.
