The Human Body has better than
650+
___________
Muscles.
One-Half (1/2)
 …and make up about ______________
of a persons body weight.
bones to support
Muscles work with _________
and move the body. They actually pull
joints
on the ___________
in order to move
the body.

There are Three (3) types of muscle in the
human body…
 1. Smooth Muscle or Involuntary Muscle
Esophagus & Stomach
Example: _________________________
Smooth Muscles work by themselves and you
cannot control them.
How many Smooth Muscles can you name?
(Talk to the people around you and see if you can
name 2 or 3)

2. The muscle that makes up the
Heart is called
Cardiac Muscle
________________________
Another name for Cardiac Muscle is
Myocardium
______________________________
Just like smooth muscles,
myocardium or cardiac muscle
works by itself (Involuntary).
Skeletal Muscles are Voluntary
3. ____________________
muscles, which means that they don’t
work unless your Brain tells them to.
 So these are the muscles that make up the
_________________________.
Musculoskeletal System
 So, Looking at the human body from the
Anatomical position…
…the MIDLINE of the body, divides the
body in two, vertically!





Muscles are connected to bones by
tough cord-like tissues called…
…TENDONS
Tendons allow muscles to pull on
the bones for movement.

Let’s look at some of the Major Muscles and
where they’re at in the body…
THE DELTOIDS and the tendons of the

Rotator Cuff, help make up the Shoulder.
BICEPS
The ________________
are antagonistic, which
means they work opposite of the Triceps.
PECTORALIS
The ___________________
Muscles are found
on each side of your chest. They are usually
PECS for short.
called _________

Below the Pecs , down under the Rib Cage are
Rectus Abdominus or _____________.
Abdominals (Abs)
your ____________________
Most people don’t understand that when these
muscles are strong, so is your back.
Quadriceps
Your _________________
or Quads for short, are
your thigh muscles. Many athletes develop large,
strong Quads.
Gluteous Maximus
Your _______________________
is the largest
single muscle in the human body. The Glutes help
in back stabilization, hip support, and speed .
So, How does the body move?
…It moves in very specific ways!
For instance, in Basketball a
Rebound
_______________
happens when
a player catches the ball after a
missed shot.
Hyperextension is movement that takes a
joint beyond it’s normal, anatomical position.
It is sometimes Bad!
But, many times it can be good!
Flexion occurs when a joint’s
angle is decreased.
Extension occurs when a joint’s
angle is increased.
Abduction
___________________
is the
movement of a limb, joint or
body part AWAY from the midline of the body.
Adduction
___________________
is the
movement of a limb, joint, or
body part TOWARDS the midline of the body.
______________
is the rotary or turning
Rotation
movement of a body part, usually
about it’s long axis.
Circumduction is the circular or
______________
conical movement of a body part. It
involves all the major movements:
Flexion, Extension, Abduction,
Adduction, and Rotation.

Why Stretch???
Stretching is important for people of all ages!
Without regular stretching, your muscles will
tighten and the range of motion in your joints will
decrease as you age. This can put a damper on
active lifestyles and even hinder day-to-day
activities
Stretching does not demand a huge time commitment, but it can give you
huge results.
Benefits of regular stretching program:





Improves flexibility and range of movement in the joints
Reduced risk of injury
Reduced muscle tension
Enhanced muscular coordination
Increased circulation to various parts of the body
Increased energy levels (resulting from increased circulation)
Delayed onset of muscle fatigue /prevent muscle soreness
Enhanced performance in daily life, sports, or other physical activity
Improved posture
Mental relaxation

What Influences Your Level of Flexibility?
Four Main Factors
Age. Younger people are naturally more flexible than older people. Why?
Muscle connective tissues have a natural tendency to shorten and lose
elasticity as you age, resulting in muscle tightness and stiffness.
Gender. Females tend to be more flexible than males.
Exercise history. Active people tend to be more flexible than inactive
people.
Temperature. When your muscles are warm (whether from exercising or
from a warmer environment), they will be more flexible than when they
are cold. Why? Increase in muscle temperature decrease muscular
resistance, which increases your range of motion.
MUSCLES MUST BE WARMED UP BEFORE YOU STRETCH.
Stretching is NOT the first thing you do in a workout.
