Valery Polyakov spent 437 days on Mir. So we have proof positive that a
duty stay of 437 days followed by return to Earth is acceptable. I

Note that Dr. Polyakov is a medical physician who took a lot of care to keep
himself in good shape. He spent several hours a day excrcising, and was not
available to do much in the way of other duties.

Consequently, upon his return to Earth he was walking unaided on his first
day back Earthside.

Other cosmonauts who spent less time in space, but did a lot less excercise,
were in much poorer shape and could not walk for a couple of days.

A regime where workers must spend more than half their waking hours
excercising gives very little time for actual work, so their productivity
will be quite low.
