Introduction to the Unit
Guided learning hours: 60
Unit abstract
A healthy body is an amazing piece of machinery which allows us to go from total rest to all out sprinting in
a matter of seconds. Trained sports people are able to run, cycle and swim marathon distances. This ability
is due to the efficiency of the physiological (how the body functions) systems that work together to allow
such activity. An understanding of these systems is essential in the sport and exercise industries in order
to begin to appreciate how the body copes with the stress of exercise, why we cannot continue to exercise
indefinitely, and how we can train these systems.
This unit explores the foundations of anatomy and physiology. It provides the learner with an understanding
of the structure and function of the skeletal, muscular, cardiovascular and respiratory systems. The short
and long-term effects of exercise on each of these systems are examined. Wherever possible, examples of
sports and exercises particular to learners’ specific pathways should be used. An outline of the energy
systems and the energy requirements of a range of sports is also covered. This part of the unit is only
intended to provide the learner with the ability to recognise which sports use either the aerobic or the
anaerobic energy systems and which ones require more energy than others.
Learning outcomes
On completion of this unit a learner should:
Understand the muscular system and how it is affected by exercise


Unit content
Understand the muscular system of the body and how it is affected by exercise
Major muscles: triceps; biceps; quadriceps; hamstrings; deltoids; gluteus maximus; gastrocnemius;
abdominals; obliques; pectorals; trapezius; erector spinae; classification; location.
Types of muscle: voluntary (skeletal); involuntary (smooth); heart (cardiac).
Muscle movement: tendons; antagonistic pairs; types of movement (concentric, eccentric, isometric).
Effects of exercise: short-term effects of exercise eg break down of muscle tissue; long-term effects of
exercise eg hypertrophy.

We have three types of muscles in our bodies:
Voluntary, Involuntary and Cardiac
INVOLUNTARY MUSCLES:
These muscles work automatically; they do not need us to tell them to contract.
They often prevent little embarrassing accidents!
eg
CARDIAC MUSCLE:
The heart is made from this specialised muscle. It is again an involuntary muscle since we
don’t have to keep telling it to keep going!
VOLUNTARY or SKELETAL MUSCLES:
These are muscles that we can control and allow us to move and participate in sport. It is
not a very pleasant thought, but when you are eating the meat of an animal, this is
voluntary muscle! There are over 500 voluntary muscles in our body and they account for
up to 40% of body mass. It is important that you know the main muscle groups:

The Structure of a Voluntary Muscle
P3
222
A muscle is made up of thousands of muscle ___________ grouped together in bundles
and surrounded by a tough outer _________. Imagine them to be a bundle of straws
surrounded in a tough coat.
At each end of the muscle are strong bands of inelastic fibres called ______________
and it is these that connects muscles to bone. The ______________ is the only muscle
in the body that is only connected at one end.
Normally one end of the muscle is attached by one or more tendons to a fixed point called
the ______________, the other end is attached to a part of the body that moves called
the _______________. When the muscle contracts it is usually the insertion that
moves towards the origin.
Think of the biceps - the origin is connected to the shoulder (fixed), the insertion is
connected to the lower arm. When the arm moves, the insertion moves towards the origin.

How muscles move.

Worksheet 1
Muscles can only pull or contract - they cannot push!
It is therefore important that muscles work in pairs, one muscle to move the body part in
one direction, the other to return it to its starting point. Because they work in opposite
directions, these paired muscles are called ANTAGONISTS. The muscle contracting is
the AGONIST or PRIME MOVER; the muscle relaxing is the ANTAGONIST. All
movement is controlled by the nervous system
Examples of paired muscles include:

Using the terms contract, relax, biceps, triceps and origin, write a description of
how the arm moves up and down.
Do the same for the leg, substituting biceps and triceps with quadriceps and
hamstrings. Use the hand written statement below as a writing frame to help with
the other questions.
In order to bend or flex the arm, the bicep ………………... and the …………………….. relax.
This causes the bicep to shorten in length. The bicep is attached to the lower arm by a
tendon, and as it contracts, it causes the arm to bend..

Types of Muscle Contraction
M3
222
Worksheet 1
Muscles are always in a state or readiness to react when needed and are in a slight state of
contraction. This is called MUSCLE TONE. Muscle tone helps with posture which in turn makes us
look good and helps all of our body systems to work.
Just to confuse things, there are 3 types of muscle contraction,
Concentric,
Eccentric and
Isometric
Use the internet to research the difference between each type of contraction. Make brief notes
on each type, then complete the table below.
Concentric Contractions
Eccentric Contractions
Isometric Contractions
Place the following activities / exercises in the appropriate columns:
Throwing a ball,
A stationary rugby scrum,

Types of Muscle Fibre
222
Worksheet 1
The two types of muscle are
RED or Slow twitch muscle
& WHITE or Fast twitch muscle
RED MUSCLE FIBRES or SLOW TWITCHING
These muscle fibres have a very good blood supply and use oxygen to create energy. They
can work for long periods of time. They are important for long distance running and
endurance activities.
WHITE MUSCLE FIBRES or FAST TWITCHING
These contract at about twice the speed of red muscle fibres. They can release a sudden
explosion of energy without oxygen. They are important for sprinting.
Think of a chicken - the breast is made of white muscle for rapid flapping of the wings –
sprinting; the legs are made from red muscle for slow walking.
These different types of muscles are obviously very important for sports people. A
sprinter needs to have more white muscle than red whereas a marathon runner should
have far more red muscle fibres.
Whilst training, it is important to develop the right type of muscle. If a sprinter trained
by running long distances, he would build up red instead of white muscle!

Types of Muscle Fibre
D1, D2
222
Worksheet 1
Place the following athletics events in the correct column.
100m, 200m, 400m, 800m, 1500m, 3000m, marathon, shot, discus, javelin, long jump, triple jump,
and high jump.
Use fast twitch muscles (White)
100m
Use slow twitch muscles (Red)
Now place the following games activities in the correct boxes
A goal keeper saving a penalty, a netballer shooting a goal, a netball referee continually keeping
up with play, a rugby scrum half constantly following the ball.
Use fast twitch muscles (White)
Use slow twitch muscles (Red)
That isn’t so easy because games players need a combination of fibres to sprint, jog and
jump when needed.
Why is it important when training to build up the right muscle fibres?

A. Leigh
D2
Types of Muscle Fibre
222
Worksheet 1
People’s muscles are not just made up of one type of muscle fibre, they always have a combination
of fast and slow but obviously different sports require different combinations. Think about a mid
field player at football or hockey, they continually run around requiring slow muscle but also have
to be able to sprint on to a pass and make a break which requires fast twitch muscle.
The following table shows how the percentage of muscle fibres varies between different
athletics events.

Although it is not possible to change red muscle into white, it is thought that another type of
fibre exists that is neither red nor white: through specific training methods they can be made to
act like one of the two specialised fibres.
THE CO-ORDINATION OF MUSCLES.
It is important to understand how we control our muscles. All muscles
are connected to the Central Nervous System (the brain) by nerve
fibres.
Sensory nerves tell the brain what is happening in the muscle, and
the brain controls the movement of the muscle through motor
nerves.
A sprinter on the starting blocks can be used as an example. When the
gun fires, the _______________ nerves in the ear tell the brain that the race has started. The
brain sends messages to the muscles along the ________________ nerves telling them to push
off the blocks. The speed that it takes to leave the blocks is called ____________
______________. It is obviously important that sports people have fast reactions so that they
can quickly respond to different situations.
