FWIW this is my current ESTIMATE of aerobic/anaerobic contributions at 1-minute and 2-minutes, from WKO modeling:
my 1-minute all-out effort is roughly 55% Glycolytic / 45% Aerobic:
my 2-minute all-out effort is roughly 36% Glycolytic / 64% Aerobic:
Looking at my data across seasons those % are pretty consistent AFTER I’ve built up some anaerobic/glycolytic capacity.
Before building anaerobic/glycolytic capacity via 60-second and shorter intervals, for example coming out of TR sweet spot base of my 2018-2019 season I’ve seen those estimates as low as 20% glycolytic / 80% aerobic (and 25% / 75% for the season). On the road that worked out to 2-minute hard/max efforts at 315W coming out of base for '18-'19 (and 329W for the full season), versus my current 90-day power best of 378W. Subjectively I can feel the difference as well.
Hence the reason for my first post above, suggesting the idea of building anaerobic/glycolytic capacity first. If you currently have a strong anaerobic/glycolytic engine and don’t expect to see any improvements, then I can see first going for more max aerobic power intervals in the 2-8 minute range.
