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

Yes. In elite athletes, this is sometimes hard. in the best trained elite athletes, bringing them to 1.1 during the test can actually be quite challenging. So if you have a short warm-up protocol, they are not well warmed up and all these kind of things, then you would easily be able to exceed this.

But if you do it more in a simulation like we did, or you have longer protocols before, you normally see that this is a little bit suppressed. So let's say that Christian normally on a view-to-max test, or let's say at the end of the view-to-max effort, he would basically click in at, let's say, 105%. Then after we started using these supplements, we could see suddenly not 103 or 102.

We basically dropped it by 10 points. So basically to 0.95 instead. Preserving the VO2. No. The CO2 was basically not as much changed. So the VO2 was increasing. Yes. So VO2 went up quite a bit. The good thing here is that now I have two other athletes obviously in the lab at the same time. So I have one athlete that comes in before Christian.

So I already do dynamic calibration of the machines before. We also have a lung simulator just because we are working with edge cases. So we need to independently validate the machines as well. So this means basically we have a large gas tank with a reference gas beyond what is used for just the calibration.

But we have a separate system where basically we have a lung simulator where we feed in, for example, six liters of oxygen, six liters of CO2. And we know this is the exact amount in the bottle, gravimetrically calibrated. And then if we don't get this out of the machine, then there's something wrong with the machine independently of the calibration.

But the good thing here is that despite this, first added in, numbers are where you expect them to be based on the training we did before. Christian comes in, you start to see some numbers that are crazy and you start, did I do something wrong here in the calibration process or anything like this?

But then also when you validate it afterwards as well, you basically know this is, the numbers are good. And then this we did then over, this was in December, January and February over nine tests more or less. We saw a little bit over time that actually VO2 max started to come down a little bit because what this indicated also was that his biochemical efficiency was not optimal either.

What that means again is that if you look at basically his oxygen consumption versus his power, so the power, power was higher as well, but the ratio was not the same as it was before. VO2 had gone up much more than the power enough.

Yes, efficiency going down. And this was then efficiency going down. Well, can we somehow get an understanding of this? And this is, of course, on this test, they actually are using a temperature pill. So we put a pill up their ass. And also the same time, we have multiple of core sensors around in the body to also measure the temperature of the body as well.

And where we basically see the same thing. We basically see an increased heat production for the same power output, basically indicating the same. You can basically think of that the reason why you have gas exchanges because we call this indirect calorimetry.
