>>None of the plans I have seen for long duration manned spaceflight seem to include any effort to induce some gravity simulation by spinning the spacecraft. Considering that astronauts may be in no condition to walk around when they arrive at their destination if they have been in zero g for over 6 months its something they should consider.

Thanks for doing the math Hilmar I did wonder what would be needed. Presumably a full 1G might not be necessary to reduce the effect of weightlessness.
