Interesting validation

Andrew Coggan had some interesting validation to the "Yes, I said no rest weeks" post. Here's what he had to say about it (please disregard the largely irrelevant last item):

"Half-life of numerous physiological adaptations to endurance training (e.g., increase in mitochondrial respiratory capacity, reduction in blood lactate, reduction in submaximal heart rate) = 7-10 d

Number of half-lives required to achieve >95% of full adaptation to a given training load = 5

Minimal frequency at which training load must be increased to drive further adaptation = 7-10 d x 5 = 35-50 d = 5-7 wk

Number of years that I've personally been building my training around 6 wk cycles = 30+"

Interesting that he hasn't gotten that much faster during that time, mm?
