Thanks AJR, great post. With regard to the motor unit recruitment patterns, I suspect that this can be constantly improved with specific training. How else could Bekele, Defar and Dibaba run the last lap of their fastest races at such incredible speed, so close to their maximum. The same thing applies to the best Marathon runners who finish with such amazing pace. Of course the cynics will claim drugs drugs drugs, but as a fast finisher myself, I know much more than they do about what is possible.

As for the original question raised in this thread - I'm not a big believer in the idea of training in different zones with the aim of achieving specific physiological adaptation. I am however a believer that you need to train a broad range of muscle fibres and that you need to learn to be able to recruit as many fibres as possible under conditions of fatigue. This may therefore be a moot debate, as although various people are arguing over the mechanisms of performance enhancement following training, I suspect our actual training suggestions would not greatly differ.
Yes I agree, training at different paces in the right way is what we really should be discussing, since all of the 'physiological zones' are employed this way without the need to focus on them specifically, which is a misconception anyway, because they can't be trained in isolation, they interact constantly.
