Running in Space!

Running in Space!


[ Music ]>>Karen Nyberg: Hi, welcome to
the International Space Station. As all of my family
and friends know, I love to run when I’m on earth. Luckily we have the
capability to run here on the Space Station too. In fact, it’s one of the
3 exercises that we do on a daily basis to help
keep our hearts and our bones and our muscles strong
while we’re here without the gravity pull of earth affecting our
body every single day. So let me show you
how we do it here. This is our treadmill
and it’s called T2. It’s located in node 3 on the
International Space Station. You’ll notice that the
treadmill can move. It’s on a vibration
isolation system like all of our exercise equipment is. And the reason is because there
are a lot of loads when you run on a treadmill and we really
don’t want to impart those loads onto the Space Station. So we have all of our
exercise equipment on vibration isolation systems. Obviously in space, we
need something to keep us on the ground when
we’re running. What we use is a harness
which is very much like a backpacking harness
and the straps are adjusted so that the load is
evenly distributed between your shoulders
and your hips just as if you were backpacking. We attach by these rings
the harness to a system of hooks and bungee cords. As you can see there’s some
stretch in the bungee cord and then we can adjust and change the number
of hooks that we use. Today I’m going to use 4 hooks. If I were to use 3 hooks it
would ride a little more load. If I used 5 hooks it would
be a little less load. And then in that way we can
adjust the amount of load on our body as we’re running. The T2 is controlled
by our laptop in front of the treadmill. And once I’m all
strapped in I can go ahead and select a protocol. Our trainers on the ground
get protocols assigned for us that we can use. Load up the protocol. This is an interval
protocol that I can do. And now you can see that
there’s a target load. The target that the — my trainers wanted me to
reach was 100 pound load. There are load cells
in the treadmill and that’s how it determining. And you can see with the 4 hooks
that I put on it’s pretty close to what the target load is. [ Background sounds ] Click okay. And then I’m ready to run. See we also have
heart rate on display. We wear heart rate
monitors and this is when — once I push start the
treadmill belt will start moving and I’ll just follow
the protocol. [ Music ] That was a great run. Not quite the same as being out
in the fresh air with the wind in your face but a
nice alternative. [ Music ]
