In the end, if it's true that mostly anaerobic work still gets the aerobic metabolism going, the opposite is also true.
I'm not so sure. In fact, the article posted by Rich Abrahams in post 44 says the opposite. Interval training improved VO2max by 5-7%, while threshold training improved it by only 2%. That's better than purely LSD training, at least, which actually resulted in a 0.7% decrease in VO2max.
