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

And that means that, for example, here to put this into context, the good thing is that when we do testing, I normally not only have Christian into the lab, I have also minimum of, let's say, one or two athletes as well into the lab. And our protocols are quite extensive. So this is also one thing that we already talked about, that protocols can have an influence on testing.

And what you do before the protocol will have an influence on your V2max. That's exactly why we're discussing, should you warm up or should you not warm up? Yes, you should, because it will normally give you, let's say, a better result when you are warmed up. But that means also that the protocol can also then have an influence on your V2max measurements.

And we normally do the V2max measurements at the end of our test, which is, you would say, but that's normal. Yes, well, we also do that simply because it also more normally simulates what they're also going to see on racing. So normally what happens in racing is that you normally also will go closer to, let's say, complete exhaustion when you get towards the end of the race.

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

And this is why it's interesting to test it there. But we don't only test it once. We even repeat it. So we do two VO2 max tests just 10 minutes apart. And even this year, we did even three tests, let's say, with less or 10 minutes apart as well. Interesting thing here is that what we see is that you normally don't get your highest view to max on the first one, even though you're exhausted.

We even see that even on the second one. More interesting thing to also deserve here is that then you would think that, I say, intuitively you can say that, okay, you would maybe also then see a higher carbon dioxide production as well. You don't. That's actually lowered. That has to, let's say, call it some priming effects more in general terms.

But also what we do see is that there are some substrates as well that actually do influence on micronutrients also that actually also can help boost your VO2max as well. Such as? Long story short, beetroots obviously have been something that people have found quite interesting over a long time. Beetroots? Beetroot, yeah. So they use beetroot concentrates.

And the main thinking behind is that when you eat nitrate, which beetroot is normally rich in, and the body converts this to nitric oxide, This helps for vasodilation. So vasodilation, you can think of this almost like a plumbing in our body. We already said that from our previous conversation that basically cellular respiration is not the limitation to your view to max.

So there are other things that are limiting factor. That means also that, for example, your cardiovascular system, meaning also actually your ability to transport blood around in your body is going to be important.

For example, one of the reasons why when you then use some supplements like that are highly enriched in nitrate, so you get a nitric oxide boost, is that this was actually, it's almost like plumbing. You're opening up the plumbing and it allows your blood to circulate faster throughout your body. This is hard to reproduce in elite athletes.
