The Five Parts of Physical Fitness
Physical Fitness (sometimes called Health Related Fitness) is
something we all possess in varying amounts. It is best remembered
if you think of 4 S’s + BODY COMPOSITION. Let’s take a
closer look at what these S’s stand for ……
trength – the force our muscles produce when
they contract against a resistance.
These players are using Static
Strength in the scrum. Static strength
means that the muscles are working
but there is no noticeable movement at
a joint. Sit against a wall or hold a
chair with straight arms for 20 seconds
to experience this!
Michael Jordan is using Explosive Strength in this
picture to jump up high to dunk the ball ! Explosive
Strength occurs only once, very quickly and with a
great deal of power. Can you name any other actions
or skills in a game that require high levels of
Explosive Strength ?
trength - continued
Rowers use a different form of
Strength in their Sport. They need
high levels of Dynamic Strength.
Dynamic Strength occurs when the
athlete has to make repeated fast,
powerful muscular contractions over
a period of time.
Look at the three pictures of sprinters below and say which
type of strength each one is using and why.
Pushing off from the blocks
Just before the start …
Sprinting Action
towards the finish line
Extension task: Identify a skill in a games activity that relies heavily on
i) Static strength ii) Explosive Strength iii) Dynamic Strength and
explain why. Which one of these three types do you think is used the
least in most sporting situations and why?
peed – the ability of the limbs to move as quickly as possible.
Football
Tennis
Volleyball
Long Jump
Write one sentence explaining why high levels of speed are an
advantage when playing the Sports above.
Extension: Can you think of a simple practice to improve Speed either
in the pictures above or in a sport of your own choice?
tamina – the ability to sustain physical activity for a long
period of time without becoming too fatigued (tired).
Another word for Stamina is Endurance. Stamina can come in two forms
depending on whether we are mainly working our heart and lungs or individual
muscles.
This Marathon runner is using many large muscle groups
and so her heart and lungs have to draw in and pump a
lot of Oxygen to her muscles.
When your heart and lungs have to work together for
long periods of time to keep you exercising it is called
CARDIO-VASCULAR ENDURANCE. Cardio means
heart and vascular means blood vessels.
We can only work at around 60% of our maximum speed
for extended periods otherwise our body cannot take in
enough Oxygen.
Muscular
tamina is when we use small muscle groups for a long period
without rest. This often involves doing lots of ‘reps’ with fairly light weights.
Below are some examples of exercises that would develop Muscular Stamina.
Can you identify the muscles being worked in Pictures A-D ?
Extension: Can you and
a partner think of a few
more exercises to develop
Muscular Stamina and
draw out a simple Circuit
Training session with 6 – 8
stations ? How long will your
Rest periods be between exercises?
A
C
HINT: Working the
same muscle twice in
a row may cause injury
or collapse.
D
B
uppleness or Flexibility is being able to use the full range of movement at a
joint. Having good Flexibility allows us to generate more power for things
like throwing and jumping because we can take our arm / leg back further.
Looks are important !
Need good body
position over the hurdle
Reach and power needed !
What problems would the people above have when performing these skills if they
had poor flexibility levels? Some clues are given under each picture ….
Extension: Can you name other skills that would benefit from high levels of
Suppleness and say why. (A skill is an action performed in a game or activity)
Body Composition refers to the amount of fat, muscle
bone and other tissue that make up the body.
