00:01
Now let's start from the
outside and work our way in.
00:04
So the second one is
the chest wall stiffens
and the thoracic
compliance decreases.
00:09
So this is what makes
breathing more difficult.
00:12
Think what has to happen for you
to be able to breathe, right?
You need that chest
wall to be compliant,
you need to be able to
expand and contract.
00:19
As you age, it becomes stiffer.
00:22
So that's why breathing
is more difficult.
00:25
Now remember those
intercostal muscles,
they're really
important in breathing.
00:30
Just for fun.
00:31
What are the three main muscles we
talked about that you need for breathing?
See if you can pause and
recall those in your notes.
00:41
Should be what the diaphragm,
those intercostal muscles
and abdominal muscles.
00:48
Good job.
00:49
Now if you didn't get
it, don't worry about it.
00:51
Just the actual act of stopping,
asking yourself a question
and thinking trying to
recall it from your brain
is powerful when
you're trying to study.
01:01
So it's much better than reading and
rereading and rereading your notes.
01:05
So keep that in mind as you're
moving through all the video series.
01:09
So we know that chest
wall gets stiffer,
we also know those intercostal
muscles are weaker,
and they're smaller,
they kind of start to shrink.
01:17
Calcification is also a problem.
01:20
See in your 30s, you're going to
have calcification of about 6%.
01:25
Now it's 45% once a
client reaches their 90's.
01:28
So things that are calcified,
don't move as well, right,
they're not as compliant.
01:34
That ribcage is what calcifies since we're
talking about the respiratory system.
01:39
So know that one of
the changes as we age,
we have increased calcification,
and in the case of the ribcage as part
of what makes that chest wall so stiff.
01:49
Now the ribcage may also
become a little smaller,
enclosed in a little
bit on the lungs.
01:54
Well what's gonna happen if my ribcage is
smaller and kind of compressing my lungs?
Right, I'm not going to be able
to take such a deep breath.
02:05
So my breath will be relatively
shallower than when I was younger.
02:11
That's what another reason why
breathing becomes more difficult.
02:15
Now let's take a look
at young Enrique.
02:18
Remember, Enrique and Jose started
at the same level of health
when they were young men.
02:24
But I want to talk
about what happens
as you're aging and still
experiencing chronic illness.
02:30
See old Enrique,
his chest wall has really become stiff.
02:34
Now part of the rationale for that
is that on top of normal aging,
Enrique was not very active.
02:41
So keep this in mind when
you're working with any client,
activity benefits just about
every part of your body.
02:48
So the more you exercise,
the less stiffness you'll
experience that Enrique is.
02:54
Because since he was not
active, he's incredibly stiff.
02:59
He's much more significantly
stiff than Jose would be.
03:02
And this is something
we can easily address.
03:04
We just need to help people
stay active and moving.
03:08
Now another problem that Enrique develop
that often happens with elderly clients
is he suffered from
osteoporosis since he turned 65.
03:17
So for the last 20 years,
his bones have really been struggling.
03:21
Enrique also didn't help matters
because he didn't take vitamins
and his diet was not one that
was a healthy balanced diet.
03:30
Now young Jose on
the other hand,
he took his vitamins, he
exercise, he made healthy choices.
03:36
Now he will also have that
calcification and stiffness,
but it's not going to
be as severe as Enrique.
03:42
So keep moving, eat healthy and
your whole body benefits from that.
03:48
Old Jose's chest wall won't have
near the changes that Enrique's did.
