Someone tapped me here, so I'll give my thoughts:
Strength training: nothing beats trudging along for years at 65-80% of max for lasting results.
Endurance training: see above; it's the same formula, ironically.
Capacity: the result of the above two strategies used intelligently. Some lactate work will maximize this but only for a short period of time, IOW, to peak.
Note the continuum: loading and duration are inversely proportional. Capacity work is trying to do both. Note velocity of movement as an additional, and oft overlooked variable--the third dimension.
These are the hardened truths that have worked for centuries, far before "exercise science" began looking through the microscope. I'm with Steve W as I can care less about the physiology that has nothing to do with the outcomes we seek--it's a black box. I'll look there if I need personal question answered, but I no longer argue that crap on a forum. E.g., why does A+A maintain aerobic capacity after you quit? It shouldn't in theory, but it seems to in practice. I've looked into this and think I have the answer, which is where it will stay... because it won't change that observation if someone slings a paper at me in contrast.
To the discussion, with VWC, Jay was trying to mimic running for an audience that was against running. Instead of debating the physiology, that we will never understand well, what is your goal? Maybe you just need to run?
I think Bret could have done a better job of prepping for A+A, but his choice of VWC wasn't even near the worst, and he learned a lot.
Underpinning this discussion is that some folks can absorb a lot more training stress than others. It's both genetic and environmental. Anti-glycolytic training is a responsible approach as a recommendation and message to a population, but if you got a guy who can absorb a lot, throw it at him.
I get it that a lot of us here are just interested in the nuts and bolts, but too often y'all forget that its the practical outcomes that matter, and these outcomes--your state of health--can only be changed through your practice.
Are you really trying to grow your LV without removing its integrity, or are you trying to wipe your own a#@ on your last day? Do you think the two have anything to do with each other?
Have a strong day ;]
