We're moving too hard.

There's too much lactate, whatever the signal is going on.

And then you'll switch to predominantly carbohydrate oxidation because carbs are really easy to break down.

You can break them down both anaerobically without oxygen and aerobically with oxygen.

Um, also there is a lot of lactate production that starts to happen as you get more and more intense, which allows your body to keep doing carbohydrate metabolism to a point until you can't do it anymore.

So the more intense you get, the more you will go to essentially 100% carbohydrate oxidation.

Um, and that's just when we think about the sheer relationship between.

intensity in that.

So if you were to do a classic VO2 max test in a lab, you would go for eight to 12 minutes running progressively harder or biking progressively harder until you couldn't go anymore.

And you would see this metabolism shift across this.

But

It will also shift with duration.

So if you were to go do like a long run or a long bike or long endurance rock, whatever it is for the people listening here for that, you will predominantly, if you're doing a really long duration activity, you're gonna be using a lot of fat oxidation.

That's a favorable adaptation because you're usually not able to sustain a high intensity for long periods of time.

You can usually only sustain

high intensity for very short periods of time.

But metabolism doesn't work in silos where you're only burning carbs or you're only burning fat.

Your body can dynamically shift between them or oscillate to kind of what it needs to supply it or what's available in the bloodstream.

So what you're taking in if you're eating during activity.

So you will use a lot of fat during that activity, assuming it's like slow to moderate intensity, where fat oxidation still can kind of happen at a large amount.
