Well they do have those tied-down-with-a-spring treadmills, but that only covers you for the duration of your workout. I don’t know anything about constructing things for use in a space station, but I can’t imagine creating such a rotating structure would be easy, cheap, or safe.. a problem with a structure rotating quickly in space could quickly cause major safety issues for the ISS I’d imagine.
- baddox 9y agoResistance training is certainly still possible, but you still lose the normal ambient resistance you get on earth just from walking around and holding your limbs in place against gravity. The difference between low-gravity and someone on Earth who doesn’t exercise much is probably much larger than the difference between a non-exercising Earthling and an Earthling who exercises. Besides, that doesn’t really work for the other physiological effects of low gravity, like the heart and circulation issues mentioned in the article.
- thatswrong0 9y agoGreat point about the treadmill. I guess my point is that I just can’t imagine that all the brilliant people involved with the ISS _didn’t_ think of a rotating structure.. but even just getting a sizable non-rotating structure cost 150B. I wonder what kind of health issues we’d see even with a rotating structure tho. Would living on such a structure really help prevent most of these issues?
- baddox 9y agoOther comments in this thread have discussed it. Sounds like NASA is well aware of rotating structures, but large ones are way too expensive and small ones cause other issues due to the fast rotation required.
