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.

I assume the impulse response model is using an exponential response of the form
y = y_0*exp(k*t) To the best of my knowledge, sjstuart might want to correct me if I'm wrong here, fitness (work capacity) uses the following exponential constant Exp(-1/45) and fatigue Exp(-1/15)
Given an accumulated base of 1000 as of yesterday, if I add a score of 100 for today, it would be computed as follow:
Fitness effect = 1000 * Exp(-1/45) = 978 + 100 * 1 = 1078
Fatigue effect = 1000 * Exp(-1/15) = 936 + 100 * 2 = 1136
The net effect therefore = -58.
If the ahtlete rests the next day then
Fitness (or accumulated Base) goes down to 1054 and fatigue goes down to 1063
sjstuart may want to correct any misleading information here though.
