Bottom line, the high intensity groups increased aerobic capacity significantly more than the less intense groups (5.5% for the 15/15 group and 7.2% for the 4 x 4 minute group. What I found to be of particular interest was the huge increase in stroke volume (amount of blood pumped per heart beat) in the high intensity groups compared to the moderate aerobic groups.
My point in referencing this article is about how to improve your aerobic capacity.
Jazz has cited similar (or perhaps the same) article(s). That's the reason I don't worry about "base." What I do will build a base. I like tabata drylands for that purpose as well.
