Transcript for NASA Connect - Better Health From Space To Earth
[00:00:11.429]
[Lindsay:] Hi, I am Lindsay
[00:00:13.069]
[inaudible] from the TV
show "Grounded for Life".
[00:00:15.369]
On this episode of NASA
Connect, you will be introduced
[00:00:17.959]
to the importance of good
nutrition and exercise.
[00:00:20.829]
You will observe researchers and
scientists using math, science
[00:00:24.269]
and technology to learn
what we can learn in space
[00:00:27.009]
about our bodies here on earth.
[00:00:28.999]
In your classroom you will
do cool hands on activity
[00:00:31.859]
to estimate serving
sizes of different foods
[00:00:34.649]
and estimate your
average daily energy needs
[00:00:37.299]
and using the instructional
technology activity you'll develop
[00:00:40.469]
an exercise program
for Norbert and Zot.
[00:00:43.329]
So stay tune as Jennifer
Pulley takes you
[00:00:45.929]
on another exciting
episode of NASA Connects,
[00:00:54.849]
better health from space to earth.
[00:01:03.849]
[00:01:17.459]
[ Music ]
[00:01:18.459]
[00:01:20.299]
[Jennifer:] Here we go five, last
four makes you breathing, three,
[00:01:25.199]
two more, two come on you can
do it last one -- there we go.
[00:01:29.269]
Alright guys.
[00:01:30.019]
So grab some water,
rehydrate, take five.
[00:01:33.609]
[Jennifer:] Hi I am Jennifer
Pulley and welcome to NASA Connect.
[00:01:38.559]
The show that connects you to
math, science, technology and NASA.
[00:01:42.399]
In addition to being your
host I am also a Certified
[00:01:44.999]
Aerobics Instructor.
[00:01:46.699]
[RJ:] Hey!
[00:01:47.009]
Jennifer that was a great
workout, but I never know I had
[00:01:50.339]
so many stomach muscles.
[00:01:51.679]
[Jennifer:] But we do.
[00:01:52.419]
[RJ:] I hope you will
help me in my training.
[00:01:54.039]
[Jennifer:] Oh!
[00:01:54.239]
What do you training for?
[00:01:55.259]
[RJ:] Want to try off
my cross country team
[00:01:57.089]
and try also in a couple of weeks.
[00:01:59.219]
[Jennifer:] RJ that is super.
[00:02:00.339]
How's your training going?
[00:02:01.739]
[RJ:] Well, I guess its okay,
[00:02:03.119]
but I really don't have too
much energy during the day.
[00:02:05.799]
[Jennifer:] Well, have you
researched what nutrients your
[00:02:08.089]
body needs?
[00:02:09.159]
Because then you have to estimate
and measure portions to make sure
[00:02:12.589]
that the nutrients are in
there and of course you have
[00:02:14.759]
to have an exercise program.
[00:02:16.169]
[RJ:] Measuring, estimating
my nutritional needs
[00:02:18.839]
and exercise program, not
really I think I mean okay.
[00:02:23.089]
Do I look overweight?
[00:02:25.139]
[Jennifer:] No, not at all; tell
me what do you eat for breakfast?
[00:02:28.859]
[RJ:] I had a soda and
a glazed honey bun.
[00:02:32.329]
It's better than nothing.
[00:02:33.679]
[Jennifer Poly:] RJ a soda
and a glazed honey bun
[00:02:35.679]
that is loaded with sugar?
[00:02:37.129]
[RJ:] Yeah!
[00:02:37.509]
The sugar provides me with energy.
[00:02:39.499]
[Jennifer Poly:] Yeah, but that
energy doesn't last throughout the
[00:02:41.509]
whole day and that's
why you get tired.
[00:02:43.429]
You need something more
substantial for breakfast.
[00:02:46.579]
You know what I think -- I
think that we need to reevaluate
[00:02:50.179]
and improve your nutrition
and exercise program and not
[00:02:53.189]
where we can get you
in tip-top shape
[00:02:54.549]
for the cross country tryouts.
[00:02:56.089]
[RJ:] Okay.
[00:02:57.639]
[Lindsay:] Guys on today's program,
we will stress the importance
[00:03:00.419]
of good nutrition and exercise.
[00:03:02.209]
Especially in the adolescent
years and that's mean you.
[00:03:05.869]
We will visit with NASA researchers
to tell us what we can learn
[00:03:09.519]
in space about our
bodies here on earth.
[00:03:12.529]
And I will offer you a challenge
at the end of the program,
[00:03:15.759]
but before we talk more about
nutrition and exercise and visit
[00:03:19.259]
with NASA researchers, we must
first understand the mathematical
[00:03:22.319]
concepts for today's program, about
your estimation and measurement.
[00:03:25.949]
During the course of the
program you will be asked
[00:03:28.269]
to answer several
inquiry based questions.
[00:03:31.029]
After the questions
appear on the screen,
[00:03:33.109]
your teacher will pause the
program to allow you time to answer
[00:03:36.749]
and discuss the questions.
[00:03:38.399]
This is your time to explore
and become critical thinkers.
[00:03:42.139]
Students working in
groups take a few minutes
[00:03:44.889]
to answer the following questions:
Number one: What does it mean
[00:03:48.339]
to measure an estimate?
[00:03:49.459]
Number two: Are both math
concepts related to each other?
[00:03:53.839]
Explain. Number three: Give some
examples of things that you measure
[00:03:58.129]
and estimate everyday.
[00:04:00.179]
Now comparing your answers
to all three questions
[00:04:02.769]
with other groups in your class.
[00:04:04.639]
It is now time to pause the tape.
[00:04:07.409]
You know guys the math concepts
sub-measurement and estimation
[00:04:10.799]
on a central part
of our daily lives.
[00:04:13.339]
Let's think about things that
you measure on a daily basis.
[00:04:16.739]
Well, you measure time with
watches, weight with scales
[00:04:20.779]
and temperature with thermometers.
[00:04:23.029]
You may think of such measurements
as exact, but the accuracy
[00:04:27.309]
of a measurement depends on
the precision of the tool.
[00:04:30.369]
In this sense, measurements can
be thought up as estimations.
[00:04:34.169]
Now let's think about things
you estimate on a daily basis.
[00:04:37.309]
Like the length of time it takes
to get ready in the morning,
[00:04:40.599]
or how long you need to
walk to the bus stop,
[00:04:43.269]
or how much cereal you
pour into the bowl?
[00:04:46.149]
Estimation, is the
powerful mathematical idea
[00:04:49.289]
that can be used both to solve
problems and to check to see
[00:04:52.719]
if our results are reasonable.
[00:04:54.779]
You know, in reality
things aren't always exact
[00:04:57.869]
and good estimations
skills are really important
[00:05:00.909]
for living successfully.
[00:05:02.309]
For example,
[00:05:03.209]
[Jennifer:] Norbert
here wants to see
[00:05:04.699]
if the galactic fitness nine
thousand treadmill will fit
[00:05:08.279]
in his spare bedroom.
[00:05:09.919]
The dimensions for the base
[00:05:11.229]
of the treadmill are one point
eight meters by point nine meters.
[00:05:15.459]
Norbert's calculator
indicates that the base area
[00:05:18.199]
of the treadmill is sixteen
point two square meters.
[00:05:21.919]
Now does the base area of
sixteen point two square meters
[00:05:25.509]
for a treadmill seem
reasonable to you?
[00:05:28.109]
Sixteen point two square
meters square meters is
[00:05:30.329]
about the size of
Norbert's bedroom.
[00:05:32.259]
That would mean the galactic
fitness nine thousand is a pretty
[00:05:36.859]
big treadmill; unless, you tear
down a wall good luck trying
[00:05:40.739]
to squeeze the treadmill
through the door opening.
[00:05:43.579]
Actually, Norbert forgot
to enter the decimal point
[00:05:46.519]
in one point eight
on his calculator.
[00:05:48.979]
But using mental math Norbert's
estimates suggested that the area
[00:05:53.009]
of the treadmill should
be about two meters
[00:05:55.299]
by one meter or two square meters.
[00:05:58.229]
The actual base area
[00:05:59.659]
of the treadmill is one point
sixty two square meters.
[00:06:03.489]
In this case, Norbert used the
estimation technique of rounding.
[00:06:07.509]
Developing methods to check the
reasonable massive results is vital
[00:06:11.589]
to anyone working with
numbers especially engineers,
[00:06:15.199]
scientists and researchers.
[00:06:17.289]
[Lindsay:] So now you have a
good idea about the concepts
[00:06:19.769]
of measurement and estimation.
[00:06:20.949]
You know, this will be a
good time to pause the tape
[00:06:23.629]
and review your answers
[00:06:24.989]
to the three questions
I asked you earlier.
[00:06:27.099]
I just want to make sure
you are on the right track.
[00:06:29.169]
So how do you apply these
math concepts of estimation
[00:06:33.199]
and measurements to
nutrition and exercise?
[00:06:36.819]
Well, to answer this question
we must first learn what good
[00:06:40.269]
nutrition is and the
benefits of regular exercise?
[00:06:43.969]
[Jennifer:] Good nutrition
is critical throughout life,
[00:06:46.349]
but is most important for kids.
[00:06:49.219]
While the body is growing
good nutrition helps
[00:06:51.869]
to insure optimal health every
cell, every organ and every system
[00:06:57.369]
in the body relies
on good nutrition.
[00:07:00.009]
How many times have you fallen
asleep in class after lunch?
[00:07:03.359]
What do you typically
eat for lunch?
[00:07:05.529]
French fries, greasy
pizza, donuts, regular soda
[00:07:09.879]
or even glazed honey buns.
[00:07:12.339]
If you establish good
nutritional habits
[00:07:14.399]
at a young age it will help
lead to continuing these habits
[00:07:17.789]
as adults and remember guys the
key to anything you eat is the eat
[00:07:22.589]
in moderation that means
you don't eat an entire bag
[00:07:26.119]
of chips while watching TV.
[00:07:27.939]
An exercise is an integral part
[00:07:30.749]
of effective weight
maintenance and weight loss.
[00:07:34.029]
Exercise helps to control your
weight by using excess calories
[00:07:38.409]
that otherwise would
be stored as fat.
[00:07:40.669]
Regulation of body weight
is dependent on the number
[00:07:43.379]
of calories you eat
and use each day.
[00:07:46.399]
Balancing the calories you
use through physical activity
[00:07:49.739]
with calories you eat will help
you achieve your desired weight.
[00:07:54.449]
[RJ:] Now I have started to
understand the importance
[00:07:57.269]
of nutrition and exercise.
[00:07:59.089]
In order to stay healthy
throughout my life,
[00:08:00.299]
I have to start maintaining
a good level
[00:08:02.059]
of nutrition and exercise, now.
[00:08:03.829]
[Jennifer:] RJ I am
so proud of you.
[00:08:05.499]
You are on the right track buddy.
[00:08:07.549]
And did you know that NASA has an
interest in nutrition and exercise?
[00:08:11.709]
That's right, astronauts living
[00:08:13.529]
on the international space station
undergo changes in their body
[00:08:17.209]
that can affect the way
they function in space
[00:08:19.809]
and when they return to earth.
[00:08:21.749]
Think about this question,
what can we learn in space
[00:08:25.139]
about our bodies here on earth?
[00:08:27.479]
Also how do we apply the
math concepts of measurement
[00:08:30.989]
and estimation to
nutrition and exercise?
[00:08:33.269]
[ Music ]
[00:08:34.309]
[Jennifer:] Good form RJ.
[00:08:35.119]
Okay, well I help RJ with his
exercise and nutrition program.
[00:08:39.459]
Let's go visit Dr. Scott
Smith, a nutritionist
[00:08:42.159]
at NASA Johnson Space
Centre in Houston, Texas.
[00:08:44.799]
Keep going RJ.
[00:08:46.749]
[Dr. Scott Smith]: Thanks Jennifer,
[00:08:49.019]
hi my name is Scott Smith I am
the lead for NASA's nutrition
[00:08:51.579]
of our chemistry laboratory.
[00:08:53.499]
Jennifer provided you with
some great back and information
[00:08:55.449]
on the importance
of good nutrition.
[00:08:57.129]
Based on the information
she provided,
[00:08:58.669]
can you come up with the
definition for nutrition?
[00:09:01.259]
What is your daily
nutritional need for calcium?
[00:09:03.369]
How are you meeting that need?
[00:09:05.169]
In your groups take a few
minutes to answer the questions,
[00:09:07.699]
your teacher can now
pause the tapes
[00:09:08.949]
so you can collaborate
with your peers.
[00:09:10.929]
Nutrition is the study for the
body uses nutrients, like calories,
[00:09:14.259]
vitamins and minerals, and how
much we choose nutrients the
[00:09:16.929]
body needs?
[00:09:18.099]
Well, good nutrition is
important for everybody.
[00:09:19.939]
NASA scientists have
[00:09:21.419]
[inaudible] our chemistry
laboratory,
[00:09:22.349]
looking how astronauts nutrients
needs are affected by space walk.
[00:09:25.889]
One area that is very important is
[00:09:27.059]
about nutrition is
keeping bones healthy.
[00:09:29.259]
Not eating foods that include
nutrients such as calcium
[00:09:31.749]
and vitamin D can
result in weak bones.
[00:09:34.649]
You can find good sources
of calcium and vitamin E
[00:09:36.659]
in dairy products, such as milk
and chesses, broccoli and spinach.
[00:09:40.829]
Calcium is probably the most
important nutrient when it comes
[00:09:42.759]
to building strong bones.
[00:09:45.119]
More than 99% of the calcium in
your body is stored in bones,
[00:09:48.309]
when you don't get enough calcium
in your diet it comes out of bones
[00:09:51.239]
to help the other tissues.
[00:09:53.009]
If you do that long enough what
happens is the bones become weak
[00:09:55.299]
and brittle, it can lead to
diseases such as osteoporosis.
[00:09:58.989]
Osteoporosis is a disease where
the bones become fragile and break.
[00:10:02.389]
The best way to counter act or
prevent getting osteoporosis is
[00:10:05.219]
to eat well and exercise
when you are young.
[00:10:08.199]
So why are we concerned about
bone loss during in space life?
[00:10:11.299]
Astronaut's actually loose
bone mass during space walk.
[00:10:14.059]
This is especially significant for
long missions such as the astronaut
[00:10:16.879]
that serve in international
space station
[00:10:18.939]
or on future missions
to other planets.
[00:10:21.129]
When astronauts return from long
missions they have an increased
[00:10:23.749]
risk fractures and
another health problems
[00:10:25.319]
because they loose
bone mass and calcium.
[00:10:27.719]
Do you have any idea,
why this occurs?
[00:10:29.909]
Does that mean they get
osteoporosis while they are
[00:10:31.459]
in space?
[00:10:32.899]
The human body get used to operate
in an earth's gravity field.
[00:10:35.809]
When humans are removed
from this environment
[00:10:37.379]
as when they travel in space.
[00:10:38.559]
Many complex changes take place.
[00:10:41.229]
While living and working in
microgravity environment,
[00:10:43.229]
your body senses that
it doesn't need
[00:10:44.769]
as much bone mass
to support the body.
[00:10:46.829]
So bone mass decreases
when you are return
[00:10:49.099]
to earth's gravity environment,
[00:10:50.569]
your body senses it needs more
bone mass to support the body.
[00:10:53.359]
So bone mass will
begin to increase.
[00:10:55.519]
Because it takes a long time
to regain the lost bone,
[00:10:58.269]
this is the period when you have
the higher risk of bone fractures,
[00:11:00.669]
because your body skeleton has a
tougher time supporting your body
[00:11:03.709]
against earth's gravity.
[00:11:06.059]
Here at NASA we conduct research
[00:11:08.249]
to understand how much calcium
is being deposited into bones
[00:11:11.529]
and how much calcium is
being taken out of bones.
[00:11:13.699]
This research involves
mathematics, especially measurement
[00:11:16.349]
and estimation skills.
[00:11:17.959]
For example, let's take a look
at the following system diagram,
[00:11:21.049]
suppose Norbert was to consume
a thousand milligrams of calcium
[00:11:23.889]
which is the daily recommended
allowance in the form
[00:11:26.089]
of large glass of milk.
[00:11:27.279]
This diagram shows the path of
calcium and other nutrients follows
[00:11:30.549]
into Norbert's body from the mouth.
[00:11:32.639]
The milk enters the stomach and
is broken down into stomach
[00:11:35.299]
[inaudible] tested by
chemical processes.
[00:11:37.559]
Approximately, eighty percent
[00:11:39.159]
of the calcium per 800 milligrams
leaves the body as solid waste.
[00:11:42.949]
The remaining twenty percent
per two hundred milligrams
[00:11:45.479]
of calcium enters
your blood source.
[00:11:47.209]
The calcium will help many
of your body functions
[00:11:49.629]
and importantly will
prevent calcium
[00:11:51.499]
[inaudible] taken out of bones.
[00:11:52.309]
This is what happens when we
don't have enough calcium.
[00:11:55.559]
About five percent or fifty
milligrams of the remaining calcium
[00:11:58.499]
that is your kidneys and is
released as liquid waste;
[00:12:01.499]
some of the calcium will
be taken up in the bone
[00:12:03.419]
and some will also be released by
bone back into the blood stream.
[00:12:06.429]
Finally, a small percentage of
calcium flows in blood stream
[00:12:09.139]
into the larger intestine
and out as solid waste.
[00:12:11.719]
To estimate how much
calcium bones are absorbing,
[00:12:14.239]
how much calcium is
being taken out of bones?
[00:12:16.649]
We can give Norbert a tiny amount
of a special form of calcium
[00:12:19.609]
for this case the blue calcium.
[00:12:21.959]
Overtime usually ten to fourteen
days we collect biological samples
[00:12:26.209]
of solid waste, liquid
waste and blood.
[00:12:28.299]
We can determine how much calcium
regular or blue in each sample.
[00:12:32.519]
By mathematically analyzing the
data we can actually estimate the
[00:12:35.729]
amount of calcium
absorbed by the intestines,
[00:12:37.769]
how much calcium is
filtered by the kidneys,
[00:12:39.689]
how much calcium is being
deposited in the bone
[00:12:42.829]
and how much calcium is
being taken out of bone.
[00:12:45.039]
By studying the whole
calcium before, during,
[00:12:47.079]
and after space life, we can tell
how the body is changing during
[00:12:50.199]
flight and what is
happening to the calcium.
[00:12:52.519]
>From our estimates we can
conclude that the amount of calcium
[00:12:55.149]
that is deposited in a bone and
the amount of calcium released
[00:12:58.289]
by the bone back into the
blood is about the same.
[00:13:01.109]
This changes when astronauts
are in space the amount
[00:13:03.399]
of calcium absorbed by the
bone is less than the amount
[00:13:05.429]
of calcium released by the bone.
[00:13:07.299]
Finally when astronauts return
to earth and recover over time,
[00:13:10.089]
the amount of calcium deposited
in the bone and the amount
[00:13:12.949]
of calcium released
by bones stabilizes
[00:13:15.079]
and returns to pre-flight level.
[00:13:17.049]
Understanding this
specific means of how bone
[00:13:19.019]
and calcium is changed during
flight can help us figure out how
[00:13:21.709]
to counter act it and also
how to prevent bone disorders
[00:13:24.009]
on earth such as osteoporosis.
[00:13:25.709]
So we are beginning to understand
the importance of nutrition
[00:13:28.169]
and how nutrition can be
important for your health.
[00:13:29.899]
Have you changed into the answers
for the question I asked earlier,
[00:13:33.479]
now it would be great time to stop
the tape and review your answers.
[00:13:36.699]
[Jennifer:] Thanks Scott!
[00:13:39.049]
Okay guy's its time for
you to become a scientist
[00:13:41.089]
and apply your estimation
and measurement skills
[00:13:43.259]
with this program
Hands on Activity.
[00:13:45.459]
It was developed by the
National Space Biomedical
[00:13:48.619]
Research Institute.
[00:13:49.979]
Hey! Let's check in on the
students at the New Mexico school
[00:13:53.409]
for the Deaf in Santa
Fe New Mexico.
[00:13:56.219]
[00:13:59.369]
[Speaker:] NASA Connect asked us
[00:14:01.389]
to show you this program
Hands on Activities.
[00:14:06.399]
[00:14:07.449]
The first activity is
called Serving Sizes.
[00:14:11.619]
[00:14:14.459]
Here are the main objectives
for the first activity.
[00:14:19.179]
Students you will estimate
serving sizes of different foods
[00:14:24.309]
and compare their estimates to
serving size information provided
[00:14:28.189]
on nutrition facts food labels.
[00:14:31.109]
[Teacher:] Good morning class,
[00:14:33.209]
food labels are another
guides offer new serving sizes
[00:14:36.559]
to describe a recommended
single portion of food or drink.
[00:14:40.219]
NASA Connect asked us
[00:14:42.269]
to investigate the question
what is the serving size?
[00:14:46.319]
[Jennifer:] Your teacher
will provide you
[00:14:47.829]
with the nutrition fact
labels from these food items.
[00:14:51.169]
One bag of frozen piece, one
box of dry breakfast cereal,
[00:14:55.799]
one bag of popcorn and a two
liter of bottle of soft drink.
[00:15:00.359]
Copies of the labels are to
be distributed to groups.
[00:15:04.009]
You are to determine
appropriate serving sizes
[00:15:06.369]
for the different foods,
right the word estimate
[00:15:09.279]
onto three paper plates
and on to one cup.
[00:15:12.809]
Mark the other three paper
plates and cup as food label.
[00:15:16.859]
On the student handout
write the name of each food
[00:15:20.189]
under the food name column.
[00:15:23.139]
For each food estimate how many
cups or fractions of cups make
[00:15:28.189]
up one serving size, record your
estimate in the second column
[00:15:32.619]
of the table and measure
the portion
[00:15:34.639]
into the estimate plates and cup.
[00:15:37.369]
Next, measure on to the food label
plate and cup the serving size
[00:15:41.659]
for each food based on
the nutrition fact label.
[00:15:45.839]
You are then to write a
short paragraph answering the
[00:15:48.349]
activities discussion questions.
[00:15:50.989]
If you have access to personal
digital assistance so PDA's,
[00:15:55.389]
the PDA is a great device
for keeping a journal.
[00:15:58.339]
You can use the infrared
capabilities
[00:16:00.409]
to peer edit journal
entries with others.
[00:16:03.429]
[00:16:04.939]
[Teacher:] Later in
this show our students
[00:16:06.949]
up in the New Mexico School
[00:16:08.129]
for the Deaf will show you the
second activity called your energy
[00:16:12.489]
needs; back to you Jennifer.
[00:16:16.259]
[Jennifer:] Now let's focus
our attention on exercise.
[00:16:19.409]
You know exercise and
nutrition go hand in hand.
[00:16:22.459]
Doctor Don Hagen, the exercise
lead in the Human Adaptations
[00:16:26.369]
and Counter Measures office.
[00:16:27.679]
At NASA Johnson Space
Centre can tell us more.
[00:16:32.159]
[Don Hagen:] Hello,
Jennifer is correct.
[00:16:34.119]
Good nutrition and
exercise are interconnected.
[00:16:37.699]
My job is the exercise lead
in the Human Adaptation
[00:16:41.079]
and Counter Measures office here
at the Johnson's Space Centre is
[00:16:44.699]
to work with the team of specialist
[00:16:47.229]
to determinate exercise
requirements for astronauts
[00:16:50.459]
and long-duration space life.
[00:16:52.399]
A long-durations space life
can be anywhere from months
[00:16:55.959]
on the international
space station to years
[00:16:58.899]
that we ever traveled
to other planets.
[00:17:01.409]
Before I continue, let's take a
look at the following questions.
[00:17:05.589]
Why is it important for
astronauts to exercise in space?
[00:17:10.039]
[00:17:11.179]
Do astronauts have
to be elite athletes
[00:17:13.659]
to endure a long duration
space life, explain?
[00:17:17.959]
What are some of the ways you
measure your level of fitness?
[00:17:21.689]
Students as your teacher pauses
the program take a few minutes
[00:17:26.039]
to answer and discuss the
questions with your class.
[00:17:29.859]
When astronauts work
[00:17:31.039]
in the international space
station they are working
[00:17:34.419]
in a microgravity environment.
[00:17:36.909]
They appear to be
floating in the ISS.
[00:17:39.869]
The apparent weightless
environment places are reduced low
[00:17:44.119]
on the leg and back muscles.
[00:17:46.509]
Astronauts hardly use
the leg muscles in space.
[00:17:49.659]
The lack of muscles activity
can cause the muscles
[00:17:53.059]
to weaken or reduce in size.
[00:17:55.679]
We call this muscle apathy.
[00:17:57.829]
It is possible astronauts
on long missions may loose
[00:18:02.009]
up to twenty five percent
[00:18:03.499]
of the muscles mass
while working in space.
[00:18:05.739]
The loss of muscle mass
[00:18:07.749]
and strength during these missions
could pose dramatic problems
[00:18:11.779]
when they return to earth.
[00:18:13.779]
Muscles support to bones in the
body and if you have a combination
[00:18:17.709]
of weak muscles and weak bones can
you imagine the harmful effects
[00:18:21.929]
your body could face?
[00:18:23.769]
To prevent muscle
atrophy astronauts must be
[00:18:26.709]
in good physical condition, while
here on earth for working in space.
[00:18:31.609]
Do astronauts need
to be elite athletes?
[00:18:34.429]
There are no physical requirements
for the astronauts other
[00:18:37.889]
than you have to be healthy and
pass a physical examination.
[00:18:41.829]
Astronauts perform physical
conditioning on a regular basis
[00:18:45.539]
as part of their training.
[00:18:47.379]
This also applies to them when
they are working in space.
[00:18:51.069]
The NASA team is responsible
for pre-flight, end-flight
[00:18:56.119]
and post-flight exercise
performance testing
[00:18:58.859]
for all astronauts.
[00:19:00.299]
We want to make sure astronauts
are in good shape before they go
[00:19:04.179]
into space, lose the least amount
of muscle mass while in space
[00:19:09.179]
and rehabilitate their whole
body when they return from space.
[00:19:13.319]
We can conduct research and
measure the muscles performance
[00:19:16.609]
of astronauts by simulating an
apparent weightlessness environment
[00:19:21.409]
here on earth.
[00:19:23.109]
Any ideas on how we can do that?
[00:19:25.459]
Exposure to space life is very
similar to prolonged bed rest;
[00:19:30.799]
remember a cause of muscle atrophy
[00:19:33.389]
in space is lack of
muscular activity.
[00:19:36.899]
That's why bed rest is a good model
because it minimizes activity.
[00:19:40.859]
And like astronauts, you loose
muscle mass primarily in the legs.
[00:19:45.969]
During prolonged bed rest
the body gradually degrades
[00:19:50.509]
and loses muscle mass, bone
mass and endurance capacity.
[00:19:54.889]
Let's look at an example of how
we measure muscle performance?
[00:19:59.619]
Suppose we use Norbert as
our test subject and want
[00:20:02.929]
to measure his exercise power
output during pre-flight,
[00:20:07.069]
in-flight and post-flight.
[00:20:09.329]
In pre-flight, we would first have
Norbert use a resistance device
[00:20:13.229]
to measures his leg power.
[00:20:15.429]
As you can see in the animation,
Norbert's legs are pretty strong.
[00:20:20.079]
He was able to lift one
hundred kilograms ten times.
[00:20:24.079]
Next, we simulate in-flight
testing by putting Norbert in bed
[00:20:28.729]
for an extended period
of time say twenty days.
[00:20:32.499]
During that period Norbert conducts
all his activities in bed except
[00:20:37.009]
for using the rest room.
[00:20:38.479]
On day twenty, we measure
his leg power again.
[00:20:42.819]
While in bed he is in the
same resistive device and see
[00:20:47.049]
that Norbert can only lift
seventy-five kilograms ten times.
[00:20:51.609]
What percent decrease in
leg power did Norbert loose
[00:20:55.249]
over the twenty days?
[00:20:56.949]
If you say twenty-five
percent then you are right.
[00:21:00.269]
After twenty days Norbert
is removed from the bed
[00:21:03.689]
and the rehabilitation process
begins to rebuild his leg muscles.
[00:21:07.849]
This is considered post-flight.
[00:21:10.229]
He undergoes an exercise
program that will allow him
[00:21:13.559]
to regain the strength
he lost in his legs.
[00:21:16.399]
I am sure glad he purchased up the
[00:21:18.719]
[inaudible] fitness nine
thousands treadmill.
[00:21:21.089]
In reality, the recovery process
is different for most astronauts.
[00:21:25.909]
It takes about thirty
days for muscles strength
[00:21:28.429]
and exercise capacity
to return to normal,
[00:21:31.709]
but bone density may
takes six months
[00:21:34.029]
to a year to return to normal.
[00:21:36.169]
The research we conduct
in space and here
[00:21:38.799]
on earth may one day benefit many
populations such as the elderly
[00:21:44.089]
or people who have
had major operations
[00:21:47.209]
and are subjected to
extended bed rest.
[00:21:50.839]
The important thing for you is that
exercise and good nutrition help
[00:21:55.289]
to build strong muscles,
bones, and endorse capacity
[00:21:59.759]
and that both are needed
throughout your life in order
[00:22:02.889]
to optimize your health
and thus for longer life.
[00:22:06.339]
Well, Jennifer back to you
[00:22:08.109]
and by the way how's
your friend's exercise
[00:22:10.779]
and nutrition program coming along.
[00:22:13.969]
[Jennifer:] Well, I think RJ
really understands the importance
[00:22:17.399]
of good nutrition and exercise
and if they go hand-in-hand
[00:22:20.429]
to maintain good health overall.
[00:22:22.399]
At the beginning of the program
do you remember RJ saying
[00:22:26.329]
that his energy level
was pretty low?
[00:22:28.669]
Well, energy fuels growth,
movement and all the process is
[00:22:32.409]
in every cell inside
the human body.
[00:22:36.029]
You know now is the good time
to go back and visit our friends
[00:22:38.839]
at the New Mexico's
School for the Deaf
[00:22:41.059]
to see how they are coming along
[00:22:42.239]
on their second activity
your energy needs
[00:22:44.649]
and how it applies to RJ's workout.
[00:22:48.249]
[Teacher:] In this activity,
[00:22:49.489]
you will estimate your
average daily energy needs.
[00:22:53.269]
[00:22:55.489]
We measure energy in calories.
[00:23:01.479]
Help RJ figure out
his energy needs.
[00:23:05.319]
You have to calculate his
baseline calorie need,
[00:23:09.699]
also called basal
metabolic rate or BMR.
[00:23:16.449]
BMR is estimated based on
gender, age, height, and weight.
[00:23:25.359]
[Jennifer:] You will work from
the baseline energy needs hand out
[00:23:28.789]
and the total energy needs
hand out which can be found
[00:23:32.269]
in the educator's guide.
[00:23:34.079]
The BMR value for men
well, in this case,
[00:23:36.849]
RJ can be calculated using
the following equation
[00:23:41.339]
where 'W' is the weight in
kilograms, 'H' is the height
[00:23:45.289]
in centimeter and 'A' is RJ's age.
[00:23:47.709]
The BMR equation for women
is different than men
[00:23:52.689]
but it also based on
weight, height and age.
[00:23:56.219]
By substituting RJ's weight, height
and age into the BMR equation,
[00:24:01.469]
the student's estimated
RJ's BMR value
[00:24:04.259]
to be one thousand six
hundred forty-five.
[00:24:07.029]
This is his baseline energy need.
[00:24:09.949]
Now if we factor in his exercise
level the baseline value needs
[00:24:14.339]
to be adjusted, because
RJ is trying
[00:24:17.019]
out for the cross country team,
his exercise level should be high,
[00:24:20.779]
meaning he is using
a lot of energy.
[00:24:23.959]
From the total energy needs hand
out we can adjust RJ's BMR value
[00:24:29.069]
by multiplying one thousand
six hundred forty-five
[00:24:31.729]
and one point nine.
[00:24:33.569]
The exercise level adjustments
are found in the handout.
[00:24:37.119]
It looks like the total
estimated energy needs
[00:24:39.839]
for RJ is three thousand one
hundred twenty-five calories
[00:24:48.659]
per day.
[00:24:49.539]
[Speaker:] Good luck to you RJ.
[00:24:51.909]
[ Music ]
[00:24:51.909]
[Jennifer:] Good job.
[00:24:52.559]
RJ is certainly on his way to
improving his exercise program,
[00:24:56.559]
and now it's your turn to develop
[00:24:58.319]
in exercise program
for Norbert and Zot.
[00:25:00.999]
The students at Princess and
Middle School in Virginia Beach,
[00:25:03.979]
Virginia will show you
this program web activity.
[00:25:07.419]
[Speaker:] There are two
parts to the web activity.
[00:25:09.779]
In the first part, called
the exercise project, Norbert
[00:25:13.089]
and Zot are on their galactic
fitness nine thousand treadmills.
[00:25:17.109]
Their doctor and trainer
have asked them
[00:25:19.269]
to exercise sixty minutes a day
and maintain an average heart rate
[00:25:23.589]
of one hundred beats per minute.
[00:25:25.749]
Their doctor has divided
their sixty minutes
[00:25:28.049]
into six ten minute periods
[00:25:30.189]
with a constant heart
rate during each period.
[00:25:33.149]
Your first job is to pick heart
rate targets for each segment,
[00:25:36.779]
to make their average come to
one hundred beats per minute.
[00:25:40.699]
Then you become the trainer and
pick a good exercise plan for them
[00:25:44.479]
and estimate their average
heart rate as per your plan.
[00:25:47.739]
In the second part
of the web activity,
[00:25:49.619]
call the heart plot project.
[00:25:51.539]
You need to measure and record
data on your own heart rate.
[00:25:55.089]
Plot your data using the
squeak heart plotter.
[00:25:58.259]
By analyzing the data
on your plots,
[00:26:00.669]
you will see how your heart
rate changes as you exercise.
[00:26:04.149]
[Jennifer:] Now it's your
turn to take nutrition
[00:26:07.569]
and exercise challenge brought you
[00:26:09.369]
by the National Space
Biomedical Research Institute.
[00:26:12.519]
Working in groups
you will choose one
[00:26:14.669]
of seven specialty menu
cards select from a person
[00:26:18.439]
with hypertension, a strict
vegetarian, a pregnant women,
[00:26:23.599]
a person who is an lactose
intolerance, a diabetic and athlete
[00:26:28.919]
in training or an
astronauts in space.
[00:26:32.779]
You will plan a menu for
breakfast, lunch, dinner and snacks
[00:26:37.219]
that needs the particular
dietary needs described
[00:26:39.899]
on a specialty menu card.
[00:26:41.399]
You will also create
an exercise program
[00:26:43.189]
for this specialty
menu card you choose.
[00:26:45.599]
The instructions and
materials can be downloaded
[00:26:48.129]
from the NASA Connect website.
[00:26:50.049]
Then submit your nutrition
plan and exercise program
[00:26:54.069]
to the NASA Connect website.
[00:26:55.779]
There is a good chance that your
plan and program will be seen
[00:26:59.509]
by millions of students
across the country.
[00:27:02.119]
[Lindsey:] Well guys that wrap up
another episode of NASA connect.
[00:27:04.559]
We would like to thank everyone,
[00:27:06.069]
who help to make this
program possible
[00:27:08.359]
and you know RJ is doing
fantastic with his fitness
[00:27:11.799]
and nutrition program and we are
going to keep our fingers crossed
[00:27:14.499]
when he makes to the
cross country team.
[00:27:16.459]
As per us at NASA we help that
you will consider how to improve
[00:27:20.429]
and maintain your good health.
