Document Summary
Assuming intensity is low, below the lactate threshold. We breakdown fatty acids and head into beta oxidation, for about 10-15 minutes, after. 10 minutes, you start to mobilize fatty acids. Need some carbs being metabolized through glycolysis, to enable fatty acids to continue to be metabolized, still will be using carbss when burning fats but at a much slower rate. Most accurate way, would have to be able to build a chamber with a treadmill, we would want to quantify the amount of heat being lost. When we measure it at the mouth we look at how much is being utilized. Obviously heart is important, if you have some heart problems, we wont be able to produce as much energy, because we are limiting oxygen delivery, effecting oxygen uptake. If you have a metabolic, mcardiles disease for example. When we talk about oxygen uptake, it can be affected by lungs, heart and metabolic uptake.
