I don't doubt your TT improved, but I would be very wary of prescribing 1 minute intervals to others as a way to improve the aerobic system.
Ok, so I'm describing Coggan's "Zone 6." If you look at table 2, zone 6 is the
ONLY zone checked for every single physiological/performance adaptation.
Everyone who wants to get faster on the bike in any circumstance can benefit from 1-minute intervals if they aren't already doing something similar.
Granted, you need to do other stuff, and zone 6 isn't the highest priority for every goal, but it's still there...
