I think they are effectively older sources.
My opinion is you get adaptations in every zone you train in. The adaptations are just different and specific to each training intensity.
exactly, you 'da man. This is exactly what I tell my guys. Along with, "you have to ride hard to ride hard and you have to ride fast to ride fast." That is training in summation. You will adapt to JRAing in zone 2 however, I don't think it's the adaptation a competitive cyclist would want.
My other favorite is the food example. All of my athletes are aware of what they eat to some degree. A few are OCD/neurotic and a few are the opposite end of the spectrum. I always tell the to listen to their grandmothers. "You are what you eat". It extends to training as well....... "you are what you train".
Specificity, Specificity, Specificity, Specificity, Specificity, & Specificity. Train how/what you race. Race with your PM and look
at the file and build workouts from that. I have never
been in a race (crit, RR, circut, CX, mtn, or TT) where my NP was below Zone 3, never. I've never seen a race file like that either.
