Base Training: science or tradition?

[Guest guest]

It is now towards the end of the yearly period during which competitive

cyclists traditionally reserve for " base training " ; those high volume,

low intensity months of 20-30 hour weeks. I've been struggling with the

validity of this notion for some time now. Presently, I seem to be

enjoying huge improvements in my endurance pace by training primarily

at and above VO2max power. Are there scientific studies that actually

support the premise of training at below race intensity to improve

endurance? If so, can someone point me in their direction and perhaps

explain the physiological adaptations that occur during such training?

Thanks!
