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

He's utilizing 25% less oxygen than Christian. In an absolute term.

Yeah, so this then touches upon one of my favorite areas, and that's biofeedback. In cycling, we have extremely good tools for biofeedback today. You have a power meter and you have a GPS. So just these two combined, for example.

Yes, like we talked about last time when you were out riding 200 watts constant, and basically you see you're getting faster. So you have this direct biofeedback because as long as you ride enough, you will basically start to get a very good feeling for when you sit at a certain power and you start doing different things. Suddenly you creep up like half a kilometer power or one.

For a person, when they start cycling or they cycle a little bit, for them, it doesn't become interesting enough yet because there are other things that is basically more challenging for them to master. But for people that do a lot of biking like yourself,

It's where you exactly start to pay attention to those, let's say even half a kilometer per hour, maybe even you're getting below that as well, where you start to really pay attention to this. And then over time, simply because wind and other factors makes a difference too. Running, this is also a place where we have really good biofeedback tools.

You have your watch, you're running, and you can have a look at it. And now we have also really good power meters in running as well. How does that work? So most of these, there are some of these power meters in running today that requires an insole. So you put basically an insole inside and it measures the forces.

Inside your shoe. And then you have other ones that are more motion capture devices. So they basically, you rather input your body weight. And since when you're touching on the ground with one foot, you're basically carrying your whole weight there.

So as long as you have a good enough motion capture device that are capable of capture the three-dimensional accelerations, you can then basically also say something, well, you know the force because you basically have to carry your weight.

No. So the motion captures today, they become so small. They're basically a small device that you attach to a shoe and they are when we validate these. Are these commercially available products? Yes. Both of these? Yes. If you go to a laboratory and you basically test this, you will basically see that. So we have been for a long time in working together with Stride.

I started working with them when they were in beta stage and we've gone through there, but they are so accurate today that when you measure on an athlete.
