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

I'm not very good at the pitches. My background is from engineering and it means also that this principle have guided me quite a lot through my journey in endurance sports or in sports in general. We embarked on a journey 10 years ago, more than 10 years ago, I would say now 15 years ago.

where we started to do what I would call extreme in-depth and longitudinal studies on two of the arguably fittest athletes in the whole world. Yeah, I think that pretty much resembles it. Obviously, a large part of that also involves technology development, simply because we are at the edge of basically what we have available information, research on.

And that means that even in some cases, we have to develop technology to allow us to even progress the understanding of getting a more granular understanding of why things are the way they are.

Yes and no. I would say that it's actually quite spread. It's a mixture between triathletes, cyclists, runners, track and field to even sailors, which is, let's say, on the explosive end of the domain, actually, and not endurance, but yeah.

There is a couple of definitions of this already, which is I have to say that it's bad when you have good terminologies, but they start to get diluted. But the original definition of FTP by the authors, I think, was Andy Kogan. And that was that basically it's, you first actually have to do a five minute all out effort. And then basically there's a short pause in between there.

And then you go to a 20 minute all out effort. And then you subtract 5% from that to find your FTP. So typically it would be your 20 minute all out minus 5%. And the reason for that is to try to get a ballparkish idea of what your, let's say, sustainable power output is possible to do over an hour. But as we have learned over the years,

is that one, we figure out that this is not as accurate always because there are a couple of other things in there. And also, unfortunately, there have become different ways to doing it. Like some people, they just do a warmup and then they do a 20 minute all out and then they subtract 5% and that's already different.

Maybe more importantly to that point is that as long as you do something consistently, so you keep the same protocol, you could say, okay, this one thing is the original thinking and that went into devising this kind of protocol. But I would say more importantly is rather to stay true to the principle of how you do it. So as long as you do it the same way each time, this is more important.

So critical power is something that you normally more extract from that you do multiple all-out efforts. And then you apply reverse extrapolation to this to basically figure out what is your critical power. So it's a more of a little bit more advanced mathematical approach to it. Typically, you would say that there are different concepts to this.

I personally have to say that I like the critical power approach a little bit better. And what is it trying to approximate? So critical power is basically where you try to divide something into two zones.
