I'm finding it hard to get the proper wording here so apologies in advance!
I'm wondering about the contribution of anaerobic sources (loosely AWC) as one moves out along the power-duration curve.
Pretty clearly, for maximal (or close to maximal training efforts) in the short-end of the range, we're operating well above CP/FTP and drawing heavily upon anaerobic sources. CP-AWC analysis would indicate that.
But what happens when we get up to the following power-durations:
Once we move to the right along the P-D, do we or can we access much of those 'AWC' sources?
My own purely 'feel' take on things is that, when I work down around the 15-20 MMP range, I feel I'm accessing a sizeable portion of 'AWC'. At the e/o an effort I'm breathing heavily (high rate of Vo2) and the legs feel empty/drained/anaerobic.
However once I get out past 30-min or so, the sensations are much different near failure. At least indoors (where I figure I'm limited by cooling somewhat), I never feel that same 'drained/empty' feeling at the e/o of a very hard to maximal effort like I do on the short-end. Sure I feel like dog-doo the last few minutes and the legs are hurting etc but I don't breathe *that* heavily nor do the legs feel absolutely horrid. Failure seems truly 'multi-factorial' .
The same holds true as I go further and further out ... about 2-hrs indoors is about the limit that I've ever done for a MMP effort and it wasn't much fun the last 30-min or so but I never felt maxed out near the end in the same way I would during a 15-20 MMP effort.
Now I realize those are my PE/sensations ... but am wondering if it is reflective of the underlying processes or just my head ...
Sorry again if the question isn't framed very well. Feel free to answer the "real question" I'm trying to ask!
