when you sit around on
the couch for an extended period time
and you try to go back out and run and you don't
use those muscles you have
weakness and deterioration in those muscles
if you don't use them and because we
don't need our legs when we get here to space
just to even support our own body weight
we have to be very very vigilant with maintaining these protocols and
to make sure that when we get back
to the planet we can actually stand
up and walk around so so
the first bit of equipment I wanted to
show us is here in the US laboratory
and it's the CEVIS it's a stationary bicycle
and it's it's very similar to a regular bicycle you might see like a
spinning class or something like that
this one's a little bit different of course
cause here in space its floating
around and so we tried to um in order not
to impart unusual loads into the
structure and also into your body that
would be a little bit awkward to try to
peddle if it was fixed to the surface or
part of the surface here in space we
use these isolation mounts they're mounted at each of the four corners
you can see that we have it allows for
play and motion and
all all the different axes up down
left and right in and out and
so as you're cycling on the
bike it will it will move around
as well um in the way that we get onto CEVIS now I've got my harness here I wanted to show you this
a lot of people and it's
really up to the
particular crew member but
to get on the bike we have handles
to hold onto and also a back pad here
and most folks will go
without the harness but you can use a
harness and I tend to use a harness
on here so this is our harness
that we're given to um to pull us down
onto the treadmill as well and I'll show you that just a few minutes but
I use this harness on the CEVIS as well to keep me
stationary on here because if it gets rocking kind of high I would
actually end up hitting my head up here
if I wasn't pulled down to
the right tension so I'll use these straps on here and um strap myself
to the TEVIS or CEVIS I'm sorry
And also we have just the biking shoes that are already clipped in and each one of us
you can see there we have the biking shoes lined up there that
each crew member has their own set of biking
shoes of course and then of course
very important part of our team
is our doctors and trainers that are on the
ground and they help us out and they actually
monitor our fitness and we use
this system here you may be familiar
with this it's a polar watch that measures your heart rate
and to use this we have this chest strap
and this transmitter that we click to the chest strap before each aerobic exercise
especially the CEVIS and the T2 um treadmill
we'll hook this together and the mounts on the front of your chest then you have this polar watch
which you'd wear on your wrist to you'd place it somewhere
where the transmitter's in direct line so it will read the
transmitter and of course that will read your
heart rate data as you and
record that for you and we downlink that to
the ground so they are able to help build
protocols for us and just kind of monitor
our fitness level and step things
up if we need to or just kinda bring things back
a little bit to keep in line with the structure that they want to have for us so when we
get back to the planet
everything is right on for us so what
we do here we put that equipment on and
then we get up onto the bicycle
the CEVIS and I would don my harness and
come up into the into the CEVIS this the way that we adjust the the exercise uh level
is we have a control box here that
we actually have our own data card that we
put in here it's got protocols that are loaded in there
for us and we changed the loading on the
cycle much like a stationary bike that you'd
see the gym or something and we can do interval
training or just scaled training
on the bicycle to a given wattage or load level on the bike so
we'd snap in like this and I'd go ahead and buckle this harness for this demonstration
I won't get fully suited up
but I'll bring this together like
this and we're ready to go we usually have a computer here that we can if
you'd like to listen to music while you're cycling
you could do that you can plug into this computer
and play music or watch a movie or something and
then over here of course our data card is
located here and that collects data for our
trainers and doctors on the ground and we'll
download that data and they'll keep track of our fitness
on the CEVIS bicycle of course you then start
peddling and we usually will maintain
we have a target rpm that we have on the
cycle and also time usually we'll have at
least a thirty minute workout on the CEVIS
