Learning Objectives
• Know the 5 aspects of HRE
• Understand how they relate to
physical activity
What is Health?
• Work with your partner to remember the
definition of health.
• Is it simply not having a cold, headache, or any
other illness or disease?
EXERCISE
• A form of physical activity which maintains or
improves health and/or physical fitness
Do you remember
how they are
linked?
5 areas of Health Related
Exercise/Fitness
HRE
1. Cardiovascular Fitness
• The ability to exercise the entire body for long
periods of time. Remember this is important
for a healthy lifestyle
Where does CardioVascular come from?
There are two parts to the cardiovascular system

The heart which pumps
the blood around the
body (cardio)

The blood vessels
divided into veins,
arteries and capillaries
(vascular)
2. Muscular Strength
The amount of force a muscle can exert
against a resistance
Different Types of Muscular Strength
• Explosive maximum force used in one
movement i.e. power, fast twitch muscle
fibres contract quickly to give a fast
powerful action e.g. high jump and shot
put
• Dynamic repetitive application of force i.e.
muscle contractions. Dynamic strength is
needed in running, cycling and rowing
• Static maximum application of force
versus an immovable object, there is little
movement but force is applied to an
object. E.g. scrum in rugby
Can you think………….?
• Can you think of some examples of these
types of muscular strength?
• Maybe all from your sport or activity
3. Muscular Endurance
• Muscular endurance is the ability to
use the voluntary muscles over a
long period of time without tiring
• For how long can you do sit ups at a
nice steady pace? This is a measure
of muscular endurance
4. Flexibility
• This is how supple you are, ‘The range of
movement possible at a joint’.
• This is important in life as people get
older if they don’t retain flexibility even
simple tasks like dressing become
difficult
• In many sports flexibility allows force to
be applied for longer e.g. swimming,
javelin thrower
• Flexibility also helps prevent pulled
muscles and tendons
5. Body Composition
• The percentage of body weight which is fat,
muscle and bone.
• We can influence this through diet and
exercise
however
• It is largely down to the ‘genes’ you have
Task
• Using your textbooks (pages 34 and 35)
write down the definitions of the 5
aspects of HRE.
• Don’t worry about making them look
attractive, we will do this later, just get
them down neatly in your exercise books.

Your Task
• The following slide will show a number of
different sports people.
• You must pick 3 of those sports people and
explain how each of the aspects of HRE are
used in their sport.
• Remember that aspects of HRE are usually
required in combination but not necessarily all
at once or all in equal amounts.
Body Mass Index (BMI)
• Use the following website to work out different
sports peoples BMI.
• BMI caculator

•
•
Is BMI a totally reliable or valid measurement?
Why?
Why not?
Why might it be inaccurate?
