Health – Related Exercise There are 5 components of health – related exercise: 1.Cardiovascular fitness 2.Muscular Strength 3.Muscular Endurance 4.Flexibility 5.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. swimmers need flexibility in their shoulders to get a good reach in their stroke. Yoga is a good activity to improve flexibility.

5. Body Composition The percentage of body weight that is fat, muscle and bone Having the best body shape for your sport High Jumpers = Tall and slim Sumo wrestlers = Heavy

Activity For an activity of your choice, give 2 aspects of health – related exercise that may be improved by training (4 marks). Health – related exercise component How performance is improved Body CompositionBeing tall, and having long arms, would help him intercept and shoot the ball; being tall and slim would also aid in jumping. Cardiovascular FitnessThis would allow him to keep running late in the game and mark his man, and run fast breaks later in the game. Example: Basketball
