If that study was of submariners, is it possible long-term high-level exposure causes the body to adapt?
I am suspicious of 0.1% having a significant effect though, given oxygen is around 20% and we naturally exhale a couple of percent CO2.

Maybe submariners are self-selected to be more physically fit, e.g. larger heart, lung capacity etc. to compensate.
