I found recently my CO2 tolerance increasing rapidly and I have a question mostly medical - physiological in nature about this subject. When increasing the tolerance in carbon dioxide what exactly happens in the body? Blood gets more space to occupy gasses or you just you desensitize the CO2 receptors? I think I read somewhere that elite free divers that train to the limits of their CO2 tolerance often have blood with higher hematocrit levels and storage properties also it is more viscous than an untrained person.
I had the idea (probably false) than when you gain in CO2 tolerance (more space in blood to occupy the extra gases?) automatically you create more space for oxygen in it?
To put it simple: Is there any changes in how much O2 body uses-stores when gaining CO2 tolerance?
Thanks in advance for any answers.
