In threads where training philosophy comes up, discussions of TRIMPS and TSS and other training models occasionally intrude. These models are not very well known, and even more poorly understood, so probably SolarEnergy, qbrain and I are just talking to each other and killing threads in those conversations. In any case, I figured I would present a brief overview of what it is that we're talking about when this terminology starts showing up.
Best case, this will introduce these models to the subset of swimmers (or coaches) who would be interested enough to use them, but didn't previously know enough to do so.
Plus, even if you're not the type to be interested in quantifying your training, it can be useful to think about workouts in this general framework.
And, at the very least, this might serve as a place to discuss some of the details without worrying about driving those other threads too far off-topic.

Thanks for the links.
I think the thing we're disagreeing on is the meaning of "fatigue".
The 7- and 15-day constants in the models weren't made up. They were fitted to real results from real athletes. (Mostly trained, but perhaps not always.) If there were no measurable effect on performance at 3 days out, then the time constant would be much shorter.
You say that "in exercise physiology, fatigue simply refers to the phenomenon that forces you to slow down as Lactate Level increase." But in the context of these models, the quantity defined as the "fatigue score" (or ATL in Coggan's model) is something very different. It's the residual effect of training (biological source unspecified) that has a negative effect on performance.
I agree that my lactate concentration, glycogen, soreness are all recovered within a few hours or days of a tough workout (fatigue in your sense). But that workout will prevent me from swimming peak times for a somewhat longer time (fatigue in the model sense).
