Weird question, I know, but how should breathing sound on the absolute limit? E.g., what does a WT pro with a huge VO2 max sound like when they are on their absolute ragged limit fighting for a mountain top finish? Are there any good examples on YouTube?
I ask because I suspect I might have some sort of airway issue that hampers my performance, but I don’t have a point of reference to know what is considered normal versus what is pathological.
I sound downright unpleasant to listen to at anything over threshold (my breathing gets very high pitched, but not wheezy, and I often have to hack out phlegm) and will basically cough for an hour after a TT, but I have a decent lung capacity and the doctor says I don’t have asthma. He couldn’t do any tests for exercise-induced asthma, stridor, etc., though.
Edit: I strongly suspect the issue I have is exercise-induced laryngeal obstruction, a form of vocal cord dysfunction. Info here: https://www.youtube.com/watch?v=jaS0qZN4X9c
