Erika and team even brought their lab out on sea two of the competition days to measure the oxygen saturation of the deep freedivers shortly after surfacing. One sign of a lung squeeze (an injury that can come from the lungs not coping with the big pressure at depth) is a reduced oxygen level in the blood up to several hours after the dive.
I showed a 99% saturation just two minutes after coming up from 57m in CWT, which is very very good. This means that my body had got the time to adjust properly, and that I was well within the depth limits that my lungs can handle. Very good indeed!
I also tried Sebastians spirometer, measuring my lung volume. On a normal inhale, I had 4,59 liters of air. This is an increase from a test last autumn which showed 4,3 liters. Most likely it is the repeated deep diving, the morning yoga and lung stretching that has worked for me.
So, even though I don't have those huge "Stig-" or "Dave Mullins-lungs", they are adapting to my freediving :)
With packing (gulping extra air) I reached 4,94 liters. This isn't as much as many other people get from doing packing, but I'm not eager to stress my lungs too much and overdo this. Packing is only safe if you train it regularly and correctly.
And again, it's not all about how much air you bring down there, it's also a lot about how good you are at saving oxygen...
Som far er det godt å se at du ikke overdriver "pakkingen". Når du da kombinerer disse kliniske resultatene med din psyke og utholdenhet, må det bli bra.
