From experience I know that packing the lungs can be very beneficial for static performances.
But analyzing what happens in the body while doing static, I came up with a question about it.
If you pack your lungs heavily, you create a strong artificial overpressure in your chest, leaving less room for the other organs etc. This causes a lot of pressure on the heart and the artery in the chest which in their turn limit the oxygen transport to the brains.
According to some scuba-literature this is quite similar to the case when scuba-divers control their buoyancy with their lungs too much and risk a blackout...
So what do you guys think, is the risk of blacking out bigger due to internally squeezing the artery in the chest??
