Blood lactate levels do not correspond to the same metabolic stress across different groups due to variations in lactate kinetics, oxidation, and mitochondrial function.

“the blood lactate levels might change between different groups and it's everything related to the lactate kinetic kinetics and LAX oxidation and lactate oxidation uh in the mitochondria so for example um Elite athlets uh to uh and and I did this was part of my doctory thesis and some of this that never published it 20 something years ago um but the same blood lactic concentration does not correspond uh to the same in an elite AET does not correspond necessarily to the same lactate concentration in a recreational athlet uh the metabolic uh stress”
