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

You don’t necessarily need precision if you’re doing the same test over and over. Relative differences become more meaningful than absolute values. Since metabolic carts are quite expensive, we use the tools we have available. Using both of the equations from that paper, I get the same ballpark for…

I honestly don’t know what Aerotune is based off of. The service was strikingly similar to Inscyd when I signed up a few months ago (I never used the service, I just looked). The VO2Max and VLaMax approximations can be pretty “off”. I think I read that Weber said VLaMax from power can be off by +/-…

Norwegian, almost to the beat. (see what I did there)

My LT1 is at about 83% of my LTHR

[image] Bigpikle: The Aerotune test is cheap enough to take a punt on Exactly. Also its not so much that it matters if you mess it up and get ridiculous results.

It was interesting to hear the interview with scott Johnston on tts he confirmed my suspicions about the early hr zones. Z1 = La1, Z2 goes up to La2.

[image] Quaestor: e doesn’t seem to make any distinction between LT1 and LT2, his model of physiology has LT, CP and W’. It appears that in very well trained cyclists (w/kg >4.5), the distinction of LT1/LT2 is useless and correlates ok with FTP. I’ve just completed the Skiba book and I see wh…

Good summary. I guess I wasn’t going crazy after all :sweat_smile:. The one thing I want to understand now is how is Xert’s model and improvement over Skiba’s (if at all).

redlude97: I believe this is @empiricalcycling opinion as well from the fatmax episode Yep, fax max fallacies. My contention with what KM presented (at the time) is whereas there is not consensus that training at/near fat max is necessary to improve fat util (his contention), there is also n…
