yeah, on the link you posted, he doesn't address it for the longer races. on the link in the original post in this thread, there is a chart that shows how to structure his race pace sets based on the distance you are training for. He list's 75's and 100's as the repeat distance for the 1500.
I came quite late in this discussion, not sure this particular point's been correctly addressed later, but work duration must be short, as one of the key principle in this form of training, well, I'd say are:
- Avoiding glycogen depletion
- Avoiding severe acidosis
- Therefore relying on ATP-CP (Creatine Phosphate, sorry I wrote it in french)
So any interpretation to the effect that one could swim bouts of 75 or 100y is undoubtedly a misinterpretation, as it would violate all these principles.
As fortress mentioned (I believe) short rest is necessary to optimize contribution of aerobic metabolism, which is probably put to contribution to restore CP levels between the bouts. If this metabolism slows down too much (ie resting too much), then it's possible that the rate of CP be compromized? And for sure, the aerobic metabolism is likely steadily trained here, as half life of most physiological changes occurring at during most oxidative metabolism is about 30sec, hence why they recommend not going over this.
Therefore an extension of the ultra-short approach, for the long distance specialist could work with any given durations, however this is a different principle. Broken intervals have been there for as long as I can remember, that's just your 60x100m on 1:25 sort of stuff for the ow marathon specialist, or your 15-30x100 on 1:25 for your 1500m specialist. Same principle here, since half life of (...) as long as you keep the rest quite short, your body barely notices that you stopped.
