Breathe-up Question

[gideon0223]

In my static (and dynamic warm up) attempts I normally breathe quite deep and slow, example: about 2 seconds inhale and a long deep 10-15 seconds exhale. I was told/read that this would slow my heartrate down and "prep" my body for the upcoming hold. The problem is I don't think this way of breathing is very efficient and the only thing it does is cause me to yawn constantly- is that a bad sign?
Now, when I do a very short hyperventilation of about 10 seconds directly before my hold I can achieve some pretty good numbers in static but I am reluctant to do this with dynamic as it may lead to earlier possibly warning free blackout.
So my question how many breaths/min are people doing and I assume they are all quick inhale, slow exhale. I would appreciate any advice.

to drop heartbeat i do 30 sec slow inhale and following 40-45 sec very very slowly exale(2-3 times), also u can close with one finger of one of your nostril., exale from your only one nostril and keep your mouth close ., .,it works...
5-10 sec relax., this taking my heartbeat from 55-60 bpm to 49bpm...

hi,

your breathing and your heartrate will slow down the more you get relaxed over the period of your preparation. i don't think having to yawn is generally bad, it would just indicate that you are getting into a more relaxed state. and that's good.

as for breathing frequency it very much depends on your state of relaxation. if you wake up in the morning and the first thing you do is check your heartrate and your breathing rhythm then that might be a good yardstick.

the idea of slow deep ventilations is to ventilate the lungs while at the same time maintain co2 levels. that's necessary for a long breath-hold.

if you achieve "good numbers" then you should consider that there is a difference between a personal best and your personal maximum. people might increase their pb but not their maximum. hyperventilation limits your potential and it dramatically increases your risk of bo.

cheers,

Hi Gideon

May I ask if you are packing? I also applied the theory that during exhale the heartrate slows down and during inhale it goes up (I actualy participated in a study which proved that true for me there was also proven that the relaxing is easier while using your lower part of the lungs to breathe less the chest)

I am packing before my attempts so I am doubting a little in the meantime that it is worth to for me to concentrate long on slow exhales as the packing will highten my heartrate dramatically for the firt minute of the attempt (static) but then will slow down by itself very fast after as I said about one minute maybe one and a half.

At the moment I am not really training a lot so not much experimenting but there are several calls for not using hyperventilation so that the oxygen preservation processes in your body kick in earlier and safe oxygen earlier. I do not have any experience on that yet.

Packing does make your heart rate increase, but it also slows it after you exhale. My baseline is around 65-70BPM. During some packing research where I was hooked up to an ECG (also another time we had ultrasounds with HR measured as well), after full pack my heartrate would go up to 100-120 BPM, then 10-20 seconds later when I exhaled my HR would go down to about 50-55 BPM and stay there for around a minute.

Cheers,

Well but if you pack on the start of the static attempt you will not exhale for the whole time of the attempt that was what I meant. And If I do a full pack before static it will sometimes go up to 160 but slow down to 40 after maybe one minute.

No, I'm not packing [I don't know how]. There is just a BIG difference between my times if I do the short hyperventilation and if I don't. PB w/o hyper= 5'02". PB w/ hyper=5'58". But if hyperventilating is ultimately detrimental to diving and accelerates BO'ing I obviously don't want to continue that procedure.

My personal theory is that if I can get almost 6 with a few short quick breaths at the end of a breathe up than I can probably achieve that time without them its just that the hyperventialtion seems ot make the 'pain/contraction/feel like i'm suffocating' part near the end of a hold way more bearable. So I assume I just need to suck up the pain a little more and push through the barrier or really work on my CO2 tolerance with more tables, apnea walking, etc...

I may be way off base; I'm really brand new to all of this...
