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

This is a good way to open up, let's say, a little bit the door to how we, because again, we are at the edge cases where basically we have to do the research ourselves. One thing we have to consider is that when we do gas exchange measurements, for example, to understand a little bit substrate metabolism.

No, we use a device which is still on all devices. There are two devices I like to use. One is the Jager Oxygen Pro with a mixing chamber, and this is important. The Parvo has a mixing chamber as well, but we have the Oxygen Jager Pro. When I've been testing in the US, for example, on elite athletes or Olympic athletes, then we have used the Parvo simply because that's the one that has been here.

Europe is more used to Jager. We don't use, maybe I shouldn't say that, we don't use the Vintu CPX, which is the successor of Jager Oxygen Pro. This is one of the devices. We use also the AEI Moxus, but this is more of a call it for specially interested people. We use also the View2Master actually quite significantly. And more and more of the testing actually have gone over to the View2Master.

We have been fortunate enough to work with them for some while. So we have the CO2 version as well. But this is where it has been in alpha mode and it requires also completely different skills than what you would normally require.

But the reason also why we do that is again, also for one of the reasons you experienced is that you see that your VO2max is maybe a little bit different when you are out and cycling and do the efforts and it's not inside the laboratory. Because also we have to remember that VO2max is on the one side, we say it's the highest oxygen consumption normally as they normalize over one minute.

That is a result of how much muscles that are involved in the work there.

Let me shed some light on it because that was basically when I started working with Christian and Gustav. Where they are today is that basically there are virtually no difference between swimming, cycling, and running. Same VO2max. More or less on the three disciplines. But it has, again, to do exactly like you said.

You can manipulate your VO2max by that you are targeting, let's say, typically shorter duration efforts. And so you start recruiting more, learn to recruit a little bit more, and also train more. Let's say fibers that you are not normally used to use so much. And this is also something that is highly plastic, much more plastic than we ever have thought it was before.

To the point where we have leading researchers in Norway that have solely focused on VO2max. And let's say they went into schools where they've done this for decades. But where we even sat down and we looked at the data and thought something has to be wrong. And that comes actually from the period when we switched from Tokyo.

olympics and then on to ironman and basically we saw a decline in view to max from me not unexpected but more there hasn't been doubt on this so it was actually quite nice to measure the decline how much so the decline in absolute or let's say in relative view to max and so it makes more sense for people is that christian and gusta typically the highest numbers we have had on them are very very high highest numbers ever measured in history i mean 90
