Gas exchange analysis can create a metabolic map showing fat and carbohydrate oxidation, and lactate levels, indirectly allowing calculation of mitochondrial function, metabolic flexibility, and training zones.

“and this is why you're going to be seeing this gas exchange the CO2 and the V2 you can just plot it into the equation and it's going to give you all that um um what I call metabolic map where where you see the the fat oxidation the the carboh hydro oxidation and then I plug in also the lactate and that's where everything comes together quite well and you can then first in an indirect way calculate the mitochondrial function and metabolic flexibility how flexible they are at using fats or carbohydrates and also you can determine training zones”
