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

That's a crossover simplification, but you distinguish between, let's say, a non-severe and a severe state, or basically where you are, again, also in the same way as FTP, trying to figure out what is the power you are capable of staying at for a prolonged time and basically where you go into a territory where small changes has a huge consequence on the duration that you're capable of holding it.

Again, this depends a little bit on how you test FTP, but I would say that how maybe FTP have been used over the last, or let's say a little bit more deviated from how the authors originally devised it, I would say that it actually is not too different. And normally you would say that critical or functional threshold power would lie slightly lower in power output than critical power.

But again, it depends very much on, let's say, also in critical power there are today, I don't know how many different definitions there are of critical power and how you should do the protocol there. But it means that normally critical power, if you look at it from a metabolic perspective, it sits somewhere between your maximum lactate steady state, or call it anaerobic threshold, and VO2 max.

So typically more close to... view to steady state or so on, but that's introducing another term that it just doesn't bring clarity.

I think for the sake of simplicity, sometimes it helps to refer to, like say, one condensed number. So you use, for example, you can say critical pace, for example, in running and swimming. And the way of testing it is not too different to what you would do in cycling.

But one thing that actually happens in the process is that you actually have access to more granular information and you are dumping down information a little bit when you call it FTP or you call it critical power.

Because more importantly, I would say, is that when you present a critical power number only or an FTP number only, you have taken two-dimensional information and made it one-dimensional, meaning that you only look at the y-axis and you take away the information that is quite critical, I would say, and that is how long are you able to sustain something.

So, for example, for critical power testing, I would say, again, also when you first do critical power testing, it's more interesting to know

Let's say how fast or how far are you able to get over one minute, for example, five minute and 15 minute, and then actually see what happens in the next time you do it for the one minute, the five minute and 15 minute, because this is actually quite crucial to understand also the balance or what's happening with the different balances in the body.

Also FTP, most people think of this as a 20 minute power. So it's even a little bit more condensed or even simpler information. But as we will probably come back to is when you're training, there are two things that normally can happen. One is that you increase your general capacity, meaning that both power and capacity, one or two are increased.
