A mathematical model of running performance estimates 0.9% of the energy yield for a 1hr long event comes from anaerobic energy sources, so a 1% value is entirely possible.the big ring said:I made efficiency a variable to explore various VO2 results. I was looking for a value that said "world champion".
Anaerobic energy yield over a 57 minute TT? I am guessing if his 4:15 IP is 90% aerobic, his 57 minute TT is going to be significantly less. acoggan mentioned previously the anaerobic contribution to a 20 / 40 minute climb is negligble. I am guessing a 57 minute TT even less of a factor.
I am not looking at only one result - the 2011 WC TT in isolation - but the IP - 10 mile - 33 minute climb values. Then comparing them to the 2011 WC TT. That's where things start to look weird.
You won't find that value in the abstract but it is located in table 1 of the fulltext article.
