Only for the Hardcore: Breathing and Respiratory Physiology At Rest and During Exercise- Q and A
Learn more in pillar 4 of the Physiologic Flexibility Cert HERE.
The main questions are
- What do we mean by oxygen delivery and oxygen saturation, and what is the relationship?
- Do we actually need to bring in MORE oxygen during exercise via respiration? What does efficiency of breathing look like?
- What happens to CO2 levels during exercise, are we offloading too much?
- What does “increased oxygen delivery” actually look like compared to sub-optimal oxygen delivery? Aerobic vs. anaerobic.
- Do we have any way to quantify CO2 tolerance right now? If so, normative values?
- Are people with hyperactive nervous system (anxiety, panic disorder, etc.) more likely to rely on anaerobic pathways quicker? (Low CO2 tolerance -> overbreathe -> low O2 delivery -> anaerobic?)
If you want a useable framework for these concepts, check out Pilar 4 in the Physiologic Flexibility Cert HERE as it is all on air- O2 and CO2.
