By the end of this booklet you should:
 Be able to describe and explain how muscles and their
composition, function and action affect movement and
performance (fast twitch for power and strength activities,
slow twitch for endurance activities).
 Know the location of the major muscle groups (deltoid,
trapezius, pectorals, biceps, tripceps, latissimus dorsi,
abdominals, gluteals, guadriceps, hamstrings and
gastrocnemius) and how activities and exercise affects these
muscles.
 Be able to explain the role of antagonistic pairs, prime movers
and synergist during a range of different physical activities.
 Be able to describe the role and function of tendons during
movement.
 Be able to explain how performance and participation can
improve as the efficiency of the muscle improves.

MUSCLES
Every movement that takes place in your body depends on muscles.
They work by shortening or contracting.
There are three kinds of muscle:
1.
Involuntary (smooth)
 Bbb
 Bbb
2.
Cardiac Muscle
 Bbb
 Bbb
 Bbb
 Bbb
3.
Voluntary Muscle (skeletal/striped)
 Bbb
 Bbb

THE MAJOR MUSCLE GROUPS
Complete the worksheet by choosing from the list below, and writing in the
boxes provided, the correct name and functions for the muscles and tendons
illustrated.
Muscles: - Gluteus Maximus – Tripceps – Gastrocnemius – Quadriceps –
Deltoids – Hamstrings – Pectoralis Major – Biceps – Achilles – Rectus
Abdominals.
Action:
Raises the arm away from the side (Abduction)
Bends (flexes) the arm at the elbow joint
Raises the body onto the toes
Bends (flexes) the leg at the knee
Pulls outstretched arms together in front of body
Straightens (extends) the arm at the elbow
Flexes the trunk forward
Straightens (extends) the leg at the knee
Straightens (extends) thigh at the hip joint
Transmits the power of the calf muscle to the
foot
Winterhill Physical Education Department
Complete the worksheet by writing in the names of the muscles shown and give
one example of how that muscle is used in sport. For example the triceps
muscle is used in putting the shot.

HOW MUSCLES WORK
 Voluntary muscles produce movement by contracting and relaxing.
 Muscles get shorter when they contract and longer when they
relax again.
 All voluntary muscles are attached by tendons to bones. These
points of attachment are called origins and insertions. Some
muscles have more than one attachment at one end (this is an
indication of strength of the muscle) e.g. the ………………………………….
and the …………………………………….
Using page 12 of GCSE PE for OCR, label the diagram below.
Muscles always work in …………………………… because they can only
…………………………… and not …………………………… These pairs are known as
…………………………… muscles. For movement to occur at a joint, one
muscle shortens (……………………………), whilst the other muscle
lengthens (……………………………). The muscle that contracts is known as
the …………………………… or …………………………… muscle. The muscle that
relaxes is known as the…………………………… muscle. Muscles which hold
the bone in place, and also contract to help the prime mover are
known as …………………………….

TENDONS
Tendons attach ………………………………… to …………………………………
Ligaments attach ………………………………… to …………………………………
As a muscle contracts, the tendons at each end of the muscle takes
the strain. Tendons must therefore be strong enough to work under
heavy loads and resist the intense, sudden muscular contractions
involved in sport, e.g. throwing the javelin or cricket ball. The
tendon of origin resists the pull of the muscle whilst the tendon of
insertion exerts the pull on the bone to which it is attached. This
causes the joint to bend or straighten.
Tendons are a connective tissue which has a less efficient blood
supply than skeletal muscle. A thorough warm up will stimulate blood
flow to the tendons and this will reduce the chance of injury to the
issue. One tendon which is prone to injury is the Achilles tendon.

MUSCLES FOR ENDURANCE AND POWER
Fast and Slow Twitch Muscle Fibres
There are two types of muscle fibre present in voluntary muscles.
 Fast Twitch Fibres
 Slow Twitch Fibres
FAST TWITCH FIBRES
Fast, powerful contractions
Burn up their supply of 02 usually
within 10 seconds. They then
have to use the body’s store of
carbohydrates as a short term
energy source. (Anaerobic
Exercise)
Tire quickly
Used for short term power and
strength activities. (Anaerobic
Activities)
E.g.
 Bb
 Bb
SLOW TWITCH FIBRES
Contract more slowly and with
less power than fast twitch
fibres
Are able to replace their 02
supply while they are working.
(Aerobic Exercise)
Can function for longer periods
of time
Used for longer term endurance
activities. (Aerobic Activities)
E.g.
 Bb
 Bb
The mixture …………..
 The fibre distribution varies from person to person.
 Is inherited. You cannot change the distribution of muscle
fibres, but you can train both types of fibre to make them more
efficient.
Winterhill Physical Education Department
In many sporting events we often use both types of fibres at
different times during the activity. Complete the table below
showing examples of the use of both types of muscle fibres in
different sporting activities.

THE EFFECT OF EXERCISE AND TRAINING
ON MUSCLES
Skeletal muscle responds to training in two ways. Voluntary muscles
become stronger and more flexible when they are exercised. This
development of the muscle is known as hypertrophy. When exercise
stops, due to injury or some other reason, muscles begin to lose the
strength and mass that was gradually building up during regular
activity. This is known as atrophy (wasting of the muscle).
Different activities rely on different muscles and muscular
requirement. With regular training muscles adapt well to the
exercise that they are required to perform. In activities which
involve heavy workloads, e.g. sprinting, new muscle fibres are
generated (muscle bulk) until the muscles are strong enough to
perform the task.
In endurance activities where bulk is of no advantage, muscles adapt
to training by utilizing energy more efficiently to delay the onset of
fatigue.
SPRINTER


Big, powerful muscles
Muscles are able to maximise
stored energy in short bursts of
all-out activity.
MARATHON RUNNER


As little bulk as possible
Muscles utilise energy much more
efficiently and for much longer
periods of time.
