Health Related Exercise

• There are 5 components of health related
  exercise
• Cardiovascular fitness
• Muscular Strength
• Muscular Endurance
• Flexibility
• Body Composition

1. Cardiovascular Fitness

• The ability to exercise the entire body for long
  periods of time

Important in any long distance event i.e.
running, swimming, cycling, and rowing. Helps in
many team sports, as you are expected to perform
over a long period of time.

2. Muscular Strength

• The amount of force a muscle can exert against a
  resistance

Important when a great force is required i.e.
lifting heavy weights, gymnastics holding a
position on the rings, or a rugby player pushing
in a scrum.

3. Muscular Endurance

• The ability to use the voluntary muscles many
  times without getting tired

Allows muscles to be used repeatedly without
getting tired. Important for long distance
sports such as swimming, running and cycling.

4. Flexibility

• The range of movement possible at a joint

Means that the performer can move easily and has
a good range of movement in their joints e.g.

get a good reach in their stroke. Yoga is a good
activity to improve flexibility.
