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

So let's say, for example, if it's a 200 meter or 400 meter, You could say that then you are typically in the range of, let's say, for the fastest swimmers, typically, let's say, two to four minutes, for example.

If you take a 1500 meter runner and you look also at the lactic concentration of them, you will also find actually pretty much the same values, let's say, among also tracking field athletes that does 1500 meters or 800 meters as well. As the moment you start to go a little bit longer, then you will actually start to see that this actually is not the case anymore.

And this is also where it helps to also distinguish between lactate concentration, let's say the highest value you're looking for, and also lactate production. Because lactate production, it's even more complicated. We can't really measure lactate production. Then we need to integrate for time. So you have to do, let's say, a pre-measurement, a post-measurement.

derive it based let's say more on calculations than when really that you can measure it directly how high you can get in lactate concentration is also valuable because it obviously tells you something about how much you are able to buffer in your body too so again what we see coming back to the main question of how do you use lactate and then basically for the sake of where you do a profile and testing

This is where I would say that for endurance athletes like, for example, marathoners, triathletes and others, which has a very, very long duration and they don't have very much top speed, here it's actually not uncommon even to see where the second infliction points, even validated by maximum lactose steady state, that actually can even be below 2 millimoles.

Yeah, because I think for those that are a little bit more into the details, I think also again here it's important to come back to that it's a lactate concentration. And one thing that we also do know in elite athletes is that elite athletes has a higher blood volume, larger plasma volume and other things as well. So this means basically that the- Absolute lactate could still be higher. Exactly.

So lactate production can be higher, but basically it shows up as a smaller concentration in the body. But what we distinguish between is basically at where comes the point where you are continuing at the same pace or power, but now lactate doesn't stay steady anymore.

So if you measure after same pace, same power, but after five minutes, after 10 minutes and so on, basically then you'll start to see that lactate still continues to rise. It doesn't stay stable anymore. This, I think, is probably one of the few concepts of where you can say that, okay, if you test it this way, it becomes very easy to translate.

Let's say the communication between people, because at the moment you start to talk about anaerobic threshold, this is more like, okay, how do you define it? This is 20-minute power. It's a 60-minute power. What kind of duration? What kind of protocol? And all these kind of things. But that's one.
