Given that there is some gravity, putting on a weighted suit to increase their mass would also make sense, although it'd be unwieldy if it's not distributed exactly the same. Plus, getting weight into space is expensive... although probably not as expensive as building a wall of death or spin gravity structure.
Why wall of death? It's gonna be just a neat cylindrical room with vaguely paraboloid walls. Even if you stop running suddenly, dropping down from 2-3 meters in 1/6 g shouldn't be anything more than inconvenient.
Weighted suit wouldn't help with the weight of your organs. They are accustomed to hanging inside you at 1g. Running on wall would provide them with that.
I think that's just what the cylindrical room is often called when it's used for motorcycles. The paper repeatedly references it, abbreviated "WoD." I don't think there's any death involved. :)
I was going to say “I’d be surprised if organ support is a large issue to an adult. We already have long term astronauts and people who are bed ridden for a long time during recovery. I would expect an issue during development though.”
It seems to say that there is a long term impact on connective tissue hardening… but it blames lack of stretching; not lack of downward force. Any regular movement would seem to fix that.
However, internally, organ tissue probably ‘bounces’ more due to gravity during movement… so less gravity means less flex of connective tissue.
> long term astronauts and people who are bed ridden
And those people lose a lot of bone mass, muscle mass, and need physical therapy to get back to normal function in 1G. Two months of bed rest will absolutely ruin you. There's a good reason astronauts need to be fit to begin with!
