What do those scientists know? Are they even smarter than the average person? Just because they couldn't get base training to work for their test subjects under carefully controlled conditions doesn't mean you won't succeed where they failed. You have to have faith that base training works, even if no evidence supports it. The pros obviously ride a lot and base involves putting in a lot of time on the bike so the pros must be doing a lot of base.
The wider your base, the higher your peak!
