Area of Study 1: Assessing physical activity and sedentary behaviour Key Knowledge Subjective and objective methods of assessing physical activity and sedentary behaviour including recall survey or diaries, pedometry, accelerometry and observational tools in relation to the National Physical Activity Guidelines.
Lesson One - Why measure physical activity? - National Physical Activity Guidelines - Introducing subjective and objective measures of physical activity
Classbrainstorm activity! WHY MEASURE PHYSICAL ACTIVITY?
Why Measure Physical Activity? • Identify concerns relating to health & fitness e.g. rise in sedentary behaviour & obesity • Identify at risk groups and trends e.g. older adults, women, indigenous, low socio-economic, non-English speaking, obese people • Monitor levels of physical activity to see whether they are active and compare against the use of screen based entertainment. • Plan appropriate physical activity interventions • Evaluate interventions
The main purposes of measuring physical activity • Active Australia survey results worksheet
National Physical Activity Guidelines Activity • The NPAG are divided into 5 categories: • Children (0-5years) • Children (5-12years) • Youth (12-18years) • Adults • Older Australians (65+) • Each of you will be given a table to fill in relating to the National Physical Activity Guidelines. You will fill the table in using the information for each sub group which will be distributed around the room. • If you would like a copy of the printed information it was taken from the following website: • http://www.health.gov.au/internet/main/publishing.nsf/content/health-pubhlth-strateg-phys-act-guidelines#rec_0_5
Domains of Physical Activity • Workplace or occupational – football player, builder, walk the stairs instead of the elevator. • Household and gardening chores – vacuuming, sweeping etc • Leisure-time activity – organised (netball) & non organised sports (walking) • Active transport – walking, cycling instead of driving for transport
Dimensions of Physical Activity Read Textbook: Nelson Physical Education VCE Units 3 & 4 (5th Edition) Malpeli, Telford, Whittle, Corrie (p.8-12) • Type – type of activity • Intensity - exercise intensity • Frequency – how often? • Duration – for how long?
Classification of Physical activity intensity • Metabolic Equivalent (MET): concept expressing energy cost • A MET rating of 1.0 occurs at rest = reference point • A MET value of 6.0 indicated an intensity 6 times that of rest
Sedentary Behaviours: • are associated with low levels of energy expenditure (1-2 METS) and linked to various negative health consequences • involve sitting staying in the same place for long periods of time (watching TV, commuting by car, reading, using a computer, etc....) • can be seen in people who are highly active - but not at the same time • only apply to people up to 18 years of age in the National Physical Activity Guidelines (as of 2010) but likely to include adults in the future
