1. The
Components
of Fitness

2. PHYSICAL FITNESS
• THE ABILITY OF THE BODY
TO ADAPT TO THE DEMANDS
AND STRESSES OF
PHYSICAL EFFORT.
• Fitness itself can not be
described in a single definition,
but must be looked at in its ten
separate components.

Body Composition
(Anaerobic Capacity)

4. Flexibility
• Flexibility –
the ability of
your muscles,
ligaments and
tendons to
stretch so that
your joints
allow large
range
movements.

5. Strength
• Muscular strength – the force that a
muscle or group of muscles can generate
against a resistance in a single contraction.

6. Factors Affecting
Strength
•
•
•
•
•
•
Recruitment of muscle fibres
Cross-sectional area of a muscle
Prestretch
Muscle fibre types
Age
gender

7. Anaerobic Capacity
• Anaerobic Capacity (Speed) - the
ability to get your body moving
quickly.
• Uses anaerobic energy system (I.e.
no oxygen but P-Cr and Lactic acid
Explosive
energy systems). Energy

8. POWER
• Power is the functional application of
both strength and speed. It is the key
component for most athletic
performances.
• Muscular Power – the ability to use a lot
of strength very quickly to produce an
explosive effort.

9. Balance
• Balance – your ability to maintain the
body in equilibrium while you are
moving (dynamic) or stationary
(stationary).

10. Muscular Endurance
• Muscular Endurance – the
ability of your muscles to
produce small efforts that
are repeated over and over
again.

11. Aerobic Capacity
• The ability to keep producing
energy aerobically and using it to
perform tasks involving the
whole body for extended periods
of time
• Aerobic capacity depends on the
ability of your heart and lungs to
deliver oxygen through your
blood to your muscles, to produce
aerobic energy.
• Long duration, low intensity.

12. Agility
• Agility – your ability to
change direction quickly
and precisely and still
retain balance.
• To be agile , you must
be able to accelerate
quickly, turn, dodge and
weave.

13. Co-ordination
• Coordination – the ability
to time your movements
so that you perform skills
smoothly and accurately.

14. Body Composition
• Body composition the ratio of the
different types of tissue
in your body (fat,
muscle, bone).
