Never mind the danger, stupidity, etc.
Lets say a person had the necessary physiological adaptations necessary to do freedive descent while holding their breath.
Okay so, I hold my breath. I sink from 0m to 50m in say 1:30. I come nack up to 0m.
Now lets say the same person, a scuba diver, does a normal scuba descent to 10m. After getting a good breathe up, he does a max inhale, and sinks to 60m in 1:30. They return to 10m, and resume breathing on normal scuba.
Is there any difference in these two activities?
Does the fact that there is twice as much oxygen present decrease the rate at which the oxygen partial pressure changes?
