Health Related Exercise HRE 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. Mnemonic • • • • • Cardiovascular Endurance Muscular Strength Muscular Endurance Flexibility Body Composition • CMMFB • Careless mice might fall backwards • Chocolate makes me feel bloated 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? Homework Make your notes on the definitions of the 5 aspects of HRE look attractive. • • • • Use colour Print photos from the internet Design a poster Use your imagination Learning Objectives Can you do the following things:• Know the 5 aspects of HRE • Understand how they relate to physical activity
