The Peter Attia Drive
#331 ‒ Optimizing endurance performance: metrics, nutrition, lactate, and more insights from elite performers | Olav Aleksander Bu (Pt. 2)

There needs to be a large enough lactate production in the muscles where you're not able necessarily to metabolize the lactate immediately. And it starts to get transported out into the bloodstream and it starts to reflect also as an increase in lactate there. So the difference is also is that depending on protocol, this will change.

So that's also a little bit of the challenges when you also start to mix something external with something internal as well.

It depends, again, how you're going to utilize it. If you are going to use it for actively, let's say, controlling the intensity outdoors, for example, using a lactate meter, then I would say it really doesn't matter.

Exactly, because the thing here is that here you're looking for more, not necessarily, here also it's important just for me to say initially that when you find, for example, a lactate concentration of LT1 and LT2, for example, or basically AT and LT, for example, or AT, LT2, but we basically say lactate 10.2 and lactate 10.1, so the first one and the second one.

And then when you do this, it's also a misconception to think that your LT2 is always a constant value because this will be influenced by many factors. We measure a concentration in the blood and the blood is influenced by hydration and all things like this.

So for example, if you have a change in hematocrit, we won't come into that, but you can easily from the beginning of the session towards the end of the session see changes in hematocrit of more than 10%. As you get dehydrated. Yes. So this will already influence the lactic concentration, but to use it as a guiding principle, it really doesn't matter how long your steps are.

Basically, what you're looking for is to find a concentration value, and then you go out into the field and you're trying to figure out where this is. You basically said, okay, if you figured this out to be for an endurance LSA, for sake of simplicity, we say one millimole and two and a half millimole. So one millimole at the lactic threshold or LT1.

And then two and a half at LT2 or anaerobic threshold AT.

I think very often it helps to think that metabolism is basically the same. The body is the same no matter what kind of sport we do. And that's why sometimes it makes it more universally easy to understand if we think of what kind of sport we do as a function of intensity and duration. So as long as you find a sport, so let's say that you compare a sport that has a certain intensity and duration.
