As exercise intensity increases, VCO2 production rises disproportionately relative to VO2, indicating a more glycolytic state, especially when recruiting Type II muscle fibers.

“so um as extracise intensity increases you start um you you oxidize I mean you need more oxygen right so your V2 increases and then you produce or give up more CO2 um so this is kind of what it shows uh when you're in a more um lipolytic state more more fatty oxidation state uh you you you still consume oxygen but you do not produce as much CO2 right when you are more into a more glycolytic State Which is higher exercise intensities uh when you're um recruiting the type two muscle fibers and therefore using more glucose for energy purposes uh you're going to consume more oxygen and you're going to produce more CO2 right”
