Exercise
Kids exercise all the time without even thinking of
it. Just being active, like when you run around
outside or play kickball at school, is a kind of
exercise. What else counts as exercise? Playing
sports, dancing, doing push-ups, and even reaching
down to touch your toes.
When you exercise, you're helping build a strong
body that will be able to move around and do all the
stuff you need it to do. Try to be active every day
and your body will thank you later!
Exercise Makes Your Heart Happy
You may know that your
heart
is a muscle. It works hard, pumping blood every day
of your life. You can help this important muscle get
stronger by doing aerobic (say: air-o-bik)
exercise.
Aerobic
means "with air," so aerobic exercise is a kind of
activity that requires oxygen. When you breathe, you
take in oxygen, and, if you're doing aerobic
exercise, you may notice you're breathing faster
than normal. Aerobic activity can get your heart
pumping, make you
sweaty,
and quicken your breathing.
When your give your heart this kind of workout on a
regular basis, your heart will get even better at
its main job - delivering oxygen (in the form of
oxygen-carrying blood cells) to all parts of your
body.
So you want to do some aerobic exercise right now?
Try swimming, basketball, ice or roller hockey,
jogging (or walking quickly), in-line skating,
soccer, cross-country skiing, biking, or rowing. And
don't forget that skipping, jumping rope, and
playing hopscotch are aerobic activities, too!
Exercise Strengthens Muscles
Another kind of exercise can help make your
muscles
stronger. Did you ever do a push-up or swing across
the monkey bars at the playground? Those are
exercises that can build strength. By using your
muscles to do powerful things, you can make them
stronger. For older teens and adults, this kind of
workout can make muscles bigger, too.
Here are some exercises and activities to build
strong muscles:
-push-ups
-pull-ups
-tug-of-war
-rowing
-running
-in-line skating
-bike riding
Exercise Makes You Flexible:
Can you touch your toes easily without yelling ouch?
Most kids are pretty flexible, which means that they
can bend and stretch their bodies without much
trouble. This kind of exercise often feels really
good, like when you take a big stretch in the
morning after waking up. Being flexible is having
"full range of motion," which means you can move
your arms and legs freely without feeling tightness
or
pain.
It's easy to find things to do for good flexibility:
-tumbling and gymnastics
-yoga
-dancing, especially ballet
-martial arts
-simple stretches, such as touching your toes or
side stretches
Exercise Keeps the Balance
Food gives your body fuel in the form of calories,
which are a kind of energy. Your body needs a
certain amount of calories every day just to
function, breathe, walk around, and do all the basic
stuff. But if you're active, your body needs an
extra measure of calories or energy. If you're not
very active, your body won't need as many calories.
Whatever your calorie need is, if you eat enough to
meet that need, your body
weight
will stay about the same. If you eat more calories
than your body needs, it may be stored as excess
fat.
Exercise Makes You Feel Good
It feels good to have a strong, flexible body that
can do all the activities you enjoy - like running,
jumping, and playing with your friends. It's also
fun to be good at something, like scoring a basket,
hitting a home run, or perfecting a dive. But you
may not know that exercising can actually put you in
a better mood.
When you exercise, your brain releases a chemical
called
endorphins
(say: en-dor-funz),
which may make you feel happier. It's just another
reason why exercise is cool!
