New discovery on the regulation of breathing

Thread Status: Hello , There was no answer in this thread for more than 60 days.
It can take a long time to get an up-to-date response or contact with relevant users.
Very interesting article.

This brings up the question: Does deliberately increasing CO2 tolerance change the sensitivity of those regions of the brain and reset them at a higher level?

I have noticed that my rate of breathing does not increase much in response to exercise, which means that I become exhausted quickly. This is although my heart rate increases normally. When I do get out of breath, it is quite sudden and extreme. I don't know whether this has anything to do with apnea training, but I don't think so.

I guess so. This is what the Buteyko therapy (for asthma) is based upon.
(Try google for Buteyko)

It happened to me as well Lucia, last time I went to play soccer I felt like I was sprinting the whole game, had to replace the goalkeeper a couple of times to catch my breath. I heard it happened to other people as well, I think that if you do just apnea with no regular excersice it is more likely to happen.
I'm guessing that the receptors are desensitized or that the body is taking the carriers apart at a quicker rate because of frequent high exposure.
 
Very interesting. Does it mean that apneists tend to get "lazy" in their breathing because of higher CO2 tolerance and it eventually catches up with them?
 
Quite often when climbing a long flight of stairs or hillside quickly my breathing will slow dramatically and become deeper, irrespective of heart rate. Upon stopping I will immediately start panting, just like after a dive. There is no doubting that this is due to apnea training combined with a cessation of aerobic exercise (although I haven't trained aerobically for 2.5 years, my reasting heart rate is in the 40's: 10-15bpm less than when I was rowing).
 
I have experienced this also. I can exercise very hard for a few minutes without any increase in respiration. Then, when I stop I gasp for air. If I start the exercise again, my breathing returns to normal. However, that only lasts for a few minutes.

I can't decide, is this useful, or just annoying? Any thoughts?

Ventilation should normally increase during strenuous exercise, with depth increasing more than the rate. In your case(s) I guess it is a combination of
1) being in a poor aerobic shape
2) learned responses (regular apnea training makes you hold your breath during activity)

The gasping after exercise is caused by the oygen debt: lactic acid has to be broken down with oxygen.

So I'm not the only one! Maybe apnea is making me even more lazy... I can't be bothered to breathe sometimes.

Will, if you haven't been doing aerobic training, have you been doing anaerobic training?

All my physiology oriented training is apnea-specific and anaerobic, e.g. interval hypercapnic DNF tables (horrendously short recoveries), dry exhale statics, max attempts UCB & DNF, statics at depth, repeat UCB dives to 22m at 1'30" intervals...
A marathon runner would have an extra 20,000 km of capillaries than me, and those are capillaries I don't want or need!

I've done dynamics with short intervals, and they are probably the most tiring thing I've ever done!

I must get to the pool soon...
