BIG PICTURE
 You
will use your prior knowledge,
powerpoint and the text book to learn about
the different classifications of muscles of the
body that create movement.
 You
will be able to identify and describe how
the muscles work together to create
movement and give sporting examples.
LESSON OUTCOMES
 All
students will be able to correctly identify
the different muscles of the body and
describe the range of movements of the
different muscles.
 Most
students will be able to describe the
antagonistic muscular contractions using
the upper arm as an example.
 Some
will be able to accurately identify the
points of insertion and origin and apply the
knowledge of antagonistic pairs to draw and
describe the movement of the muscles in the
upper leg.
CLASSIFICATIONS OF MUSCLE
FIBRES

1.
2.
3.
There are 3 classifications of muscle fibres that
work throughout the body.
Voluntary muscle fibres
Involuntary muscle fibres
Cardiac muscle fibres
Complete the table and answer the following;
 Can you identify different examples of these
different types of muscle?
 Describe how the different classifications of
muscles work
VOLUNTARY MUSCLES



Voluntary muscles are our primary concern
during physical activity.
Why is this?
Voluntary muscles create the movements
needed during physical activity.
RANGES OF MOVEMENT AT JOINTS

What joins a muscle to a bone?

How does this create movement?

The different movements created have different
names.

Read through page 156 and complete the table on
your worksheet.
TASK
Use the text book.
1.
Identify the different movements of muscle
p140-142. Complete the box regarding muscles
and movements.
MINI REVIEW
MUSCLES AND MOVEMENTS


Teacher points at a muscle.
Students identify one of the following with their
partner;
Name and movements created by the muscle.
2. An example of using that muscle in sport.
1.
HOW DO MUSCLES PRODUCE MOVEMENT?

Muscles are made of thousands
of fibres that can contract
(shorten).

As muscles contract then relax they
move the bones and limbs at the
joints

Muscles are in groups to let us
make opposing movements

When one muscle contracts the
muscle that controls the opposite
action will need to relax

Why is it important for a
sportsperson to understand this?
EXAMPLE OF HOW YOUR MUSCLES WORK






In the upper arm the large
muscles are the biceps and
triceps
They are opposite each other
They are attached to the bones
by tendons
When the biceps contract they
will pull on the radius and lift the
lower arm
The bone in the upper arm is the
humerus
The arm is lowered by the
triceps contracting and pulling
on the Ulna.
MOVING THE MUSCLES OF YOUR ARM

The bicep contracts (This is called
the agonist it is the main muscle that
moves or prime mover)

The triceps must relax (this is the
antagonist or opposing muscle that
must relax)

The radius moves up

Try to make this movement
yourself without relaxing the
triceps. What is happening?.
TASK

Use your knowledge to explain how movement
is created in the upper leg.
Extension work
1.
2.
Complete the supplementary worksheet describing
muscle actions for sporting movements.
Students to make up their own questions to test the
knowledge and understanding of their peers on the
content involved in lesson 13.
MINI REVIEW

of muscles work using the following words.
Agonist
 Antagonist
 Tendon
 Muscle
 Origin
 Insertion
 Bicep / quadricep
