Components
Fitness definitions and components
3. The Definition of Fitness
What does it mean to be Fit?
Physical fitness can be defined as; ‘The ability to
carry out tasks with vigour and alertness,
without undue fatigue and with ample reserve
energy to enjoy leisure time pursuits and to
meet unforseen emergencies’.
World Health Organisation
Health can be defined as; ‘The absence of
disease or illness’. Also includes wellness
(quality of life).
Obtaining an acceptable definition of fitness and
being healthy is difficult as they are often
vague and very generalised.
4. Physical Fitness as a
Continuum
Everyone has some form of fitness.
By training we can move towards the maximum
end of the scale.
Less activity means a decreased fitness level.
Low Adequate Maximum

5. The Components of Fitness
Fitness is made up of many components.
These components are used in sporting settings and can be
trained to improve performance and fitness levels.
These components can be broken down into two groups;
Health related and motor-skill.
6. Activity - Brainstorm
In pairs brainstorm as many fitness
components as you can (2 minutes)
Share with the main group and come up
with a class list

Most essential component at rest
and during recovery.
Examples: Team sports netball,
football, hockey, soccer, volleyball,
water, polo, basketball, lacrosse and
rugby. Racquet sports such as
tennis and squash. Extended athletic
events such as the marathon,
triathlons and cross country skiing.
VCE Physical Education - Unit 4
10. Muscular Strength
The force or tension a muscle or
muscle group can exert against a
resistance in one maximal
contraction (1RM)
It is an integral part of anaerobic
power, muscular power and local
muscular endurance and is
rarely used in isolation.
Improvements; Circuit and weights
training improves the explosive
acceleration required for
muscular strength.
VCE Physical Education - Unit 4
11. Local Muscular Endurance
The ability of a muscle or group of
muscles to sustain an activity for a
short time in the face of
considerable local fatigue (eg
push-ups).
Tasks may require anaerobic
energy in addition to aerobic
because contraction of the muscle
may occlude (block) the blood
vessels that supply the muscle
tissue.
Closely linked with muscular
strength.
Improvements; Continuos training or
weight training
VCE Physical Education - Unit 4
12. Anaerobic Power and Speed
Anaerobic Power
Anaerobic power is required for most sports. It is explosive movements performed
quickly.
It produces its energy in the absence of oxygen. An athlete’s power is a
measure of their anaerobic pathways.
Speed
Speed is the ability of the body to perform a task or movement quickly.
Power and speed are very closely related.
Improvements ;
In sprint or high-level interval training (at least three times per week), keep the
heart rate in the ‘training zone’ for at least 20 minutes.
Undertake 20–80-metre interval running sprints, starting with a ‘walk back’
recovery and progressing to a ‘jog back’ recovery.
Undertake 300–600-metre running ‘cruises’
The same interval concept will produce anaerobic gains, when used for related
sports such as cycling or swimming.
Weight training can also improve anaerobic power.

13. Flexibility
Flexibility is the ability to gain the
range of movement required for a
particular sport.
Flexibility is based on skeletal and
muscular interaction.
It is very important for injury
prevention, ease of movement and
aesthetic appearance.
Flexibility can be static (Eg. Sit and
reach test) or dynamic (Eg. Range
of motion during a skill).
Improvements; Flexibility training.
VCE Physical Education - Unit 4
14. Body Composition
Proportion of bone, muscle and fat in an
athlete.
Body composition can be measured three
ways;
1. Somatotypes
Endomorph – Short/fat
Mesomorph- muscular
Ectomorph – Tall/thin
2. Body fat determination
Densitometry – Submerging the athlete
in water to determine lean body mass
(LBM) in comparison to fat mass (FM)
Skinfold measurements – Skin
thickness is measured at various sites
on the body.
3. Body mass index (BMI)
Height / weight2
VCE Physical Education - Unit 4
17. Muscular Power
Powerful movements lasting for a few
seconds only.
It is the ability to exert a “maximal”
contraction in one explosive act.
Dependant upon speed and strength.
Max power is generated when the speed of
contraction is around 35% of its max and
the force contraction is about 35% of its
max.
Power is required for most sports Eg, field
events such as shot-put, discus, javelin,
high jump, long jump and hammer throw,
tackling in football or rugby, a spike in
volleyball etc.
VCE Physical Education - Unit 4
18. Agility
Ability to change direction with maximal speed and control
Combination of; power, speed, flexibility, balance and
coordination.
Important in sports which require sudden changes of
direction.
Improvements; Training can improve speed, reaction time,
flexibility, coordination and balance – thus improving
agility.
VCE Physical Education - Unit 4
19. Coordination
Ability to link muscle groups to appear
well controlled and efficient.
Involves the nervous system and
muscular system working
harmoniously in hand-eye and foot-
eye coordination activities.
Improvements; Can be developed
through specific skill training and
through enhancement of core stability
and balance.
VCE Physical Education - Unit 4
20. Balance & Reaction Time
Balance Reaction Time
The ability to remain in a state of Ability to react to an outside
equilibrium while performing a stimulus
desired task. Improvements; Practice with starter
Dynamic – moving guns, overload with quicker
Static – Not moving stimuli (eg quicker squash balls).
Relies on core stability
Improvements; Training methods
such as Pilates and Swiss
balls.
