You need a pretty big ship to do that fast enough for Earth gravity and not have the astronauts nauseous all the time. You could use a tether but NASA has had problems with tethers in the past and is a bit shy about them.

I can't find any studies on reduced gravity (it would be really hard to test), but there's no reason to assume that something like half a gravity + exercise and supplements wouldn't significantly reduce health issues.
