Skill related fitness components
More difficult to improve than
straight forward health related
fitness components.
Repetitive skill drills!
The brain learns patterns of
movement with regular practice and
becomes better at anticipating –
information passed more efficiently
via central nervous system to our
muscles.

Health Related Components of
Fitness
All affect our ability to exercise and
to follow an active, healthy and
balanced lifestyle
All improved by regular exercise /
training
Some more important for some
sports than others

Health & fitness
Some health related components are more
important in some activities than others
Which components are more
important?
Cardio vascular endurance
Muscular endurance

Cardio Vascular Endurance
(Stamina)
CV system involves
the heart, the
blood vessels and
blood
All about efficient
transportation of
oxygen around the
body
Benefits of a healthy balanced
lifestyle for the CV system
Healthy capillaries and, through exercise, an
increase in capillary density and efficiency.
Healthy heart > reduced risk of heart disease >
through exercise, lower resting heart rate.
Good blood circulation > with exercise, increased
volume of blood pumped by heart.
Healthy blood pressure. With exercise, a decrease
in resting blood pressure.
Feeling energetic because of uptake of oxygen by
the body > with exercise, increase in
haemoglobin and red blood cells which help to
carry oxygen.
Feeling less tired both physically and mentally.
Capillaries
Muscular endurance
Capacity of muscles to
contract repeatedly, or keep
going without rest.
With a healthy, balanced
lifestyle (activities like
swimming, running) muscles
develop greater aerobic
potential (hypertrophy of slow
twitch muscle fibres).
Muscles also adapt
anaerobically (activities like
sprinting, weight lifting)
muscles develop strength and
power (hypertrophy of fast
twitch muscle fibres)
Muscular endurance
 Size and number of
mitochondria
increased.
Increase in myoglobin
content.
Onset of fatigue
delayed because of
higher maximum
oxygen uptake (VO2
max).
Cardiac hypertrophy
Speed
Not just running
Eg acceleration of arm
when throwing javelin
Is largely innate – we
are born with certain
%age of fast twitch
fibres
Can improve the fibres
we do have with
training and can
improve technique
Speed
As part of a healthy lifestyle it is
important to be able to move quickly
(eg to catch a bus).
Regular exercise improves speed
because your heart and lungs are
more efficient and your muscles are
more efficient in producing energy.
Your joints are healthier and move
more freely
Strength
 “ the maximum force
that can be developed
within a muscle or
group of muscles
during a single
maximal contraction “
 As part of a healthy
lifestyle we need
sufficient strength to
lift and carry objects.
 Strength is also an
asset in many sports,
eg hitting a ball hard
in tennis
Strength
A healthy active lifestyle which includes an
exercise like cycling can enlarge slow
twitch muscle fibres, which gives greater
potential for energy production.
The size and number of mitochondria is
increased, as is the myoglobin content in
the muscle cells
Muscles benefit anaerobically from
activities like sprinting, causing muscles to
hypertrophy.
Flexibility
Greatest range of
movement possible at a
given joint.
Governed by elasticity of
ligaments, tendons and
strength of muscle groups.
As part of a healthy
lifestyle it is important to
have flexibility or
suppleness to prevent
strains and move faster
and more effectively
without being injured.
Flexibility
With a healthy balanced lifestyle your
flexibility will improve because:
Your ligaments and supporting tissues can
stretch further.
The blood flow to your muscles is
improved.
The rise in muscle temperature can help
muscle flexibility.
Regular stretching will improve your range
of movement.
