fitness
Some more important for some
sports than others
All improved by training
Cardio

Skill related fitness components
More difficult to improve than
straight forward physiological 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.
Agility
Balance

Timing
Speed
Of reaction
Cardio Vascular Endurance
Efficiency of
respiratory and
circulatory systems
Train the heart &
lungs – greater
volume of O2 blood
to muscles
More efficient
removal of lactic
acid
Muscular endurance
Capacity of
muscles to perform
repeated
contractions for
extended period
without fatigue
setting in
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
Strength
Hypertrophy of
muscles
“ the maximum
force that can be
developed within a
muscle or group of
muscles during a
single maximal
contraction “
Flexibility
Greatest range of
movement possible
at a given joint.
Governed by
elasticity of
ligaments, tendons
and strength of
muscle groups
Agility
The ability to move
in a controlled way
and to change
direction, turn,
stop and start
quickly.
Balance
Ability to keep our
centre of gravity
(bulk of
bodyweight) over
our base of
support. Implies a
sense of control.
Timing
Performing a skill
at exactly the right
time = effective
Coordination
Interaction
between body’s
motor (movement)
system and
nervous system.
Enables various
parts of body to
combine in
producing desired
movement or
sequence of
movements.
Speed of Reaction

Movement time
