Pelizzari is wrong?

[shoutatthesky]

On page 117 of his book "Manual of Freediving" Pelizzari says "When bodily development is complete it is not possible to increase lung capacity...." "Lung capacity is developable only during the growing years...."
Does this mean as a 27 year old I must now give up my dreams of being the best I could have been or is he wrong? Can I still increase my lung capacity through stretching and the like?

 

[SEDATE]

not pelizzari is wrong, the translater of the book from italy to english

 

[shoutatthesky]

is that a yes or a no? what?

 

[Waterenthusiast]

I don't think he is wrong, and if i remember right William trubridge did the translation into english, he could answer most precise on the matter i think.
Anyway as i understand it means that you cannot increase your total lung capacity TLC (packing not included), but with training, and thus gained flexibility of the chest and diaphragma, you increase your vital capacity VC by reducing your residual volume RV. Correct me if I'm wrong

lung aproximately in all human like that section 625gr(rigth) and 567gr(left) ..think that like 2 sponges you have in while traing there is a limit and end-point , when you come to an end the section will be 625gr/567gr relax cylce but when you fill up it will be more dif from beginning , i mean before training , let say 6lt at beginning may be will 8 .2 lt at the end he means here

surely holding your lungs(packed especially) full of air will be creating an outward stretch on your lungs? Would this force not stretch lungs larger or am I misunderstanding the mechanics of the lungs? Am I mistaken to think in terms of capacity rather than efficiency?

The quote is probably correct in a technical sense. The rib cage, which you can't change (short of surgery) after full growth is obtained, does set a limit on lung capacity. However, almost nobody uses the full potential of their rib cage. In practice, almost everyone can substantially increase the amount of fresh air they can carry with them on a dive or static. That is the point, isn't it?

Leaning to belly breath and diaphram stretches will increase the quantity and quality of what is inhaled and do it without the penalty of extra flotation, which is no small penalty. Personal experiance, it works great. Stretching the intercostals can increase the total amount of air the lungs can hold. It takes a lot of stetching, but some divers report considerable success.

So, have at it and good luck.

Thanks Connor, you said it all. I am off to do some stretching.:t

Yes, that is what i wanted to express
thanks Connor

Things that will increase your long-term vital lung capacity:

Development of inspiratory muscle power
A scientist friend of mine did research on whether it was possible to increase the concentration of alveoli/unit volume with aerobic exercise....apparently, her results seemed to indicate that this was indeed the case, but I haven't read here thesis so ....

[samdive]

another theory is that women can increase their VLC by having a baby as pregnancy increases diaphragm flexibility....

not one I am willing to try at this stage though!

I don't recommend diving on a full inhale anyway, so the way I see it your lung capacity is irrelevant. In fact you're probably better off with a smaller lung capacity.

I start each dive with only 5L or less, though I can get 11L with packing (FVC).

 

[shoutatthesky]

Thanks Eric
I don't try to fill my lungs to max capacity when doing a breathhold either. I don't know if what I do is packing - I have never been trained formally. I just feel the pressure of all that air wanting to escape from my lungs is counterintuitive to my main goal whilst holding my breath - to relax. Having said that I feel the more air you can comfortably hold the more oxygen your body will have available for extending the duration of the hold?

understanting mechanics of the lung can make you one step ahead, simple when you get inhale how much you take in your rib cages moves up and out when exale rip cages goes down and in muscle conctarctings around rib cages controled by your brain but if you know the sytem how works easy to achive many things like to fill efficent your lung or hold your breath without getting stress
over %80 %85 fill your lung kills apnea reflex it short cut the sytem for a while and gives you more stress and pressure and makes you BO
i do not know how to explain holding breath not related by means of how much you in while inhale 1/2 or less you can easly achive 5-5:30 min hold ,
elacity of your rib cage more important at deep dive attampt , keep in mind !

But why does Tom pack so much that he has to let some air out in the first min of his breathhold?I know that all my best results were with packing....

Static is another topic...
...I do not think that anyone can say that a static can be better without a lot of air. Even though one person with smaller lungs can do a longer static than another with bigger lungs I am absolutely sure that the same person will do better with more air. Not being able to relax with packed lungs is just a matter of training.

CWT diving is another thing since you have to deal with shallow water blackout and narcosis and such.
