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

The other thing that happens there is that at some point we are all time limited and this is where we need to pivot. So we need to pivot or as a prioritize what is more important for us. Is it the more explosive or speed or is it more endurance? And then it becomes more interesting for how you guide the training to understand what's happening between this different power or pace and durations.

Probably in the same way today that we say something we just say, call, and now in the world of chat GPT and everything, we just call something AI. Basically, an extremely broad term that try to encompass more or less the exact same thing that we already talked about. Basically, let's say the difference between where

something is steady and where it goes over to unsteady or basically for where you can hold something for a longer duration and where it goes to shorter duration it's a misconception to think that anaerobic threshold means basically when you become anaerobic because that's not the case yeah it's a continuum of course it's not a switch yeah yeah

So again, obviously, because this is a more, but if we then, let's say, bring it over more to lactates as a tool for trying to figure out where this is. And again, this opens up a whole new world of definitions.

But to try to answer it simply, I would say that typically anaerobic threshold when you use lactate, and let's say that you use, for example, gold standards or maximum lactate steady state, this will normally sit below the critical power of FTP.

Yeah. Also, what's important here is that when we say anaerobic threshold is that when we talk about the differences here, the differences here depend a little bit on what kind of athlete you are, whether you are a high power athlete or endurance athlete. So if you're a high power athlete, typically you'll see that there are larger differences between this.

So the percentage difference between this will be larger. Our endurance athletes, it would be smaller, but you could basically call this minute differences. We are talking percent differences. It's not like These are going to be 10% apart in terms of power, anything like this. We talk about percentages from a couple of percents to maybe five, worst case, maybe 10. Okay.

And then lactate threshold, just adding more definitions.

So lactate threshold, I would say the lactate threshold has probably more of a result of limitations in the measurement method, because we know that lactate is something you produce all the time, even when you are sleeping. So The difference here is more where you're looking at where you find a first infliction point on a lactate curve when you do less an increase in intensity.

So one thing that is maybe easy to get wrong here is that it looks like when you do increasing, so if you start low enough power or low enough pace, it looks like, oh, there is no increase in lactate production. The problem is the way we measure. We don't measure lactate in the muscle. We measure in the bloodstream and for it to basically be reflected on the instrument.
