Exercising in space.
[ Sound Effects ]
At the Exercise Counter Measures Laboratory,
we have a treadmill that's not mounted like your treadmill
at home or in the gym.
We put our treadmill vertically
and have a runner running on his back.
The purpose of this is to try to mimic the treadmill
that we have on the space station.
Everyone should be getting as much exercise as possible,
but the reasonable amount that is suggested is an hour a day.
The astronauts are allotted two and a half hours a day,
which sounds like a lot of time, but when you take out the fact
that time includes getting dressed,
setting the equipment up, cleaning up, showering.
So they are allotted extra time for that.
On Earth, we can do things like play sports and other things
that are active, for exercise,
that they can't do on the Space Station.
It's a little difficult to have a football game
on the Space Station.
So, we have them doing things like treadmill exercise,
which basically, so they can run.
We have stationary bicycles.
We have resistive exercises, which mimic lifting weights.
