I've never seen a VO2 max interval prescribed above 4'. You also get an extra ~30" of VO2 max benefit each interval as the heart recovers from the high zone.Seriously?
The classic go-to VO2max interval for runners has been mile repeats since at least the 1970s, and it takes most people a lot longer than 4 min to run a mile. :)
The classic Hickson protocol of 6 x 5 min (which coincidentally was what I started doing back when I transitioned from running to cycling in 1975) was also first published in 1977.
As for heart rate remaining high during recovery, that alone doesn't guarantee that you're still stressing the cardiovascular system as much as you were during the work period, since stroke volume could be declining rapidly - note the dip in estimated SV immediately after each interval in the image below.
