Wait so I don't really understand, did Frederic said that trained freediver and untrained freediver do not have different / significantly different tolerance of CO2? Or I got it wrong? So what "training" he suggested in increasing CO2 tolerance?
Frederics reply to your question is: Well, not exactly. Apnea changes sensitivity in the short term (after a session for example) but the long term effects are not verified. If I test the sensitivity of ventilatory centers to CO2 away from an apnea session and compare this sensitivity between freedivers and controls there is no difference. This indicates that there is a short term effect but this effect does not last in time. All apneas will stimulate your ventilatory centers, repeated moderate apneas with small recovery will produce the most effect. Just remember that if you produce CO2 it is because you are consuming oxygen.CO2 increases very slowly in the body due to our buffering capacity while oxygen decreases rapidly.
Very interesting topics discussed and explained in a simplified way for us to understand. Thanks!
