How do people approximately calculate their LT1 and LT 2 without a blood test?

[image] Quaestor: Thanks. Seems like this is some evidence that I’m wrong Not wrong necessarily, just using Skiba’s exercise physiology jargon (some of it dated, some of it just his preference) while the rest of us were in the context of LT1, LT2, FTP, etc. Different models. I don’t have the…

He goes on to define his four zones. < LT LT - CP CP - VO2max > VO2max

And also it appears to give better results when cycling (particularly when inside) as opposed to running.

His new book is really good and relies heavily on math and CP

Interesting… Is that really saying that ‘pro cyclists’ are producing 201w at 153bpm for LT1? Looks odd given 51 yr old Joe Average me produces about 210w at 153w DFAa1 0.75??? Or am I completely missing something here? (Very possible :wink: )

Good question. We have to wait until the study is published, it was accepted by the journal, should be out soon.

True - but even the LT2 numbers look really low to me. I’m not entirely sure what female pro’s numbers are like but surely LT2>280w?

Looking forward to it. Although I’m the poster child for the common refrain: “biology, the science for scientists that are bad at math”. LOL. So we will see.
