5 Components of Fitness.
1.
Flexibility- which is the
range of movements of
your joints.
2 Types of Stretching
1.
2.
Static: Stretching the
muscle to a point
where a pull is felt
and holding it for 1530 seconds

stretching the muscle
with a bouncing
movement.

during vigorous
exercise.

5 Components of Fitness
4- Muscular
Strengthwhich is the
greatest
amount of
work your
muscles can
do at a given
time.
5 Components of Fitness
5.
Body
Compositionwhich is the
amount of fat
tissue your
body has
compared to
the amount of
other tissues.
Muscular System

Your body has three
basic types of muscle
tissue:
Cardiac muscle
Special type of tissue that forms the wall of
the heart.
 This muscle pumps blood through your
cardiovascular system.
 Cardiac muscle is an
involuntary muscle,
meaning they work without
a person’s conscious control.

Smooth muscle


Smooth muscles
are located in
places such as the
intestines and blood
vessels.
Smooth muscles
are involuntary
muscles.
Skeletal muscle



Skeletal muscles are
attached to your bones and
cause body movement.
Adults have 206 bones
There are over 600 muscles
in your body.
Skeletal muscle


Skeletal muscles are
voluntary, meaning they are
under conscious control.
Skeletal muscles account for
40%-50% of your total body
weight.
There are five basic actions of
Skeletal Muscles:
Flexion:


This means bending
or folding.
Flexor muscles
generally curl the
body forward into
the fetal position.
Extension:



This means stretching
out, the opposite of
flexion.
Extensor muscles
stretch the body as in
bending backwards with
your arms over your
head.
Like waking up in the
morning and stretching.
Abduction:


This means drawing
away
In body terms, it is a
movement to the side
as in lifting your arm or
leg away from your
body when you step to
the side or reach out to
the side.
Adduction:


This means drawing
inward
A sideways motion
opposite to
abduction as in
bringing an arm or
leg back towards the
center of the body.
Rotation:


This means turning around,
like a wheel.
Movement around the axis
of a bone like the
movement of your head
when you look from right to
left or the movement of your
hand and wrist when you
use a screwdriver.
 Flexors
and extensors work in
opposition.
 Abductors and adductors work
in opposition.
 Rotation uses muscles that
work in combination.
