Exactly. Since the Jay Johnson reference is a running one, it's worth stating that paying attention to the "chassis" is more or less Canova's approach...and is very different from what CrossFit or H.I.I.T. proponents are preaching. Canova uses extensive rest, extensive training well below LT, and also targeted hill and general resistance circuit work only as a part of his overall, incredibly successful, program. And he is clear that his focus is not on strength systems per se.
In the context of skiing, it's interesting that some of Canova's work is not too different from what, say, Maze does, if you simply tweak it for the demands of alpine ski racing.
I can't speak for the racers, but for an all day recreational skier, skiing is anaerobic, but a series of anaerobic activities, recovery from which depend on a moderately good aerobic conditioning such that the next series of anaerobic activities can take place to their full potential...
Think 45 seconds. Even if your first run is all-out, 100%, leaving you gasping and bent over, think about 45 seconds as a more or less hard limit beyond which the aerobic system has to predominate. For most people, they will in fact be relying predominantly on the aerobic system for energy well before 45 seconds. Even on their first run. Because of the volume and lower intensity typical of recreational skiers, they also will be relying on anaerobic systems less, and less often, than they might think.
Again, many people will think that because they have started to breathe hard, that their effort was all anaerobic, but it is not the way it works.
So, why the disconnect between what coaches and athletes are in practice doing -- developing huge "aerobic and anaerobic bases" as explained by the High Performance Director for USSA -- and also what we know the basic physiology dictates, on the one hand, and on the other hand some of the views on here, such as the advice to perform "limited aerobic conditioning" and that skiing has "next to no aerobic component", and that the US is wrong for having its athletes develop their aerobic base...and even posters questioning that those aerobic bases are being developed?
The actual athletic practice is very clear, and relevant to the recreational skier. As is Canova . It is possible to get very relevant strength work while also addressing the critical need of aerobic system development as part of skiing preparation.
