I wonder if it's really required to have 1g gravity in order to avoid this. It's much easier to artificially create, say 1/6g (moon) gravity by rotation than 1g, since rotational speed required is quite a bit slower.
I wonder how much the rotation speed really matters. It comes down to the tensile strength of the material required to hold everything together I suppose but most metals should be able to handle 1g just fine. Once it's rotating you don't need much energy to keep it going, just enough to overcome any frictional losses from whatever interfaces happen to be required.
To echo some of the points from the aurora book, I think that the human body is really well optimised for 1G environments. We know that there are issues in zero gravity. As you adapt to 2G, you may well get stronger but the stress and strains may have a severe effect on health, life expectancy. Hate to think about the effects on your blood pressure etc
That's actually seen in anime. In Dragon Ball Z, Goku trained in 100 G. I remember thinking it was clever. It reminded me of Spain national football team training for some weeks in La Paz previous to Mexico World Cup in 1986. The idea is enduring harder conditions (> altitude -> less oxygen) to overcompensate.
