  1. VCE UNIT 3 2009PHYSIOLOGICAL AND PARTICIPATORY PERSPECTIVES OF PHYSICAL ACTIVITY LEVELS OF ACHIEVEMENT UNIT 3 SCHOOL ASSESSED COURSE WORK: 25% UNIT 4 SCHOOL ASSESSED COURSE WORK: 25% END OF YEAR EXAMINATION: 50%

  2. MARK ALLOCATION – UNIT 3 • There are 4 assessment tasks (2 per outcome) in both units 3 and 4. • All four tasks at Unit 3 now have equal weighting – 25 marks each. • At both Units 3 and 4, each outcome has one compulsory designated assessment task plus a second task for which there is a choice of formats available.

  3. PERFORMANCE DESCRIPTORS • Performance descriptors are specific for each assessment task and will assist you in seeing how the marks are allocated. • PD’s provide you with a guide to the standards expected. • They describe the knowledge and skills typically demonstrated by students who have achieved scores within each range on the assessment task/s.

  4. PERFROMANCE DESCRIPTORS CONTINUED… • Refer to handout • As can be seen there are 5 mark ranges provided e.g. 21-25 marks • Each mark range is accompanied by typical performance features • The descriptors make it easier for the teachers to make a judgment on the standard of work presented.

  5. SATISFACTORY COMPLETION • 2 OUTCOMES PER UNIT – ONE FOR EACH AREA OF STUDY. • 4 ASSESSMENT TASKS PER UNIT – 2 PER OUTCOME IN BOTH UNIT 3 AND 4 • THE DECISION IS BASED ON THE TEACHER’S ASSESSMENT OF THE STUDENT’S PERFORMANCE ON ASSESSMENT TASKS DESIGNATED FOR EACH UNIT

  6. TYPES OF ASSESSMENT TASKS UNIT 3 AND 4 2008 • Some tasks will be compulsory and other tasks will provide you with a range of options. • Possible options include: written reports, tests, media analysis’, lab. Reports, data analysis’, case studies, multimedia presentations and/or structured questions.

  7. Unit 3: Physiological and participatory perspectives of physical activity • Unit 3 consists of two areas of study: • Monitoring and promotion of physical activity • Physiological requirements of physical activity

  8. Area of Study 1: Monitoring and promotion of physical activity • The National Physical activity guidelines • Methods of assessing physical activity • Settings based approaches to promoting physical activity – schools, community and workplaces. • Strategies for physical activity promotion • Theoretical models to explain participation in physical activity.

  9. Area of Study 2: Physiological requirements of physical activity • Characteristics and interplay of energy systems for physical activity and recovery • The conversion of food to energy, including fuels required for physical activity • Muscular fatigue mechanisms – fuel depletion, metabolic by-products, dehydration.

  10. Unit 3 Outcomes • OUTCOME 1 • Students should be able to analyse individual and population levels of participation in physical activity, and evaluate strategies that promote adherence to the National Physical Activity Guidelines. • (Area of Study One)

  11. Unit 3 Outcomes continued. • OUTCOME 2 • Students should be able to analyse the role and relative contribution of the energy systems during physical activity. • (Area of Study 2)

  12. Unit 4: Enhancing Physical Performance • Consists of two Areas of Study: • Enhancing fitness through training • Strategies for enhancing performance.

  13. Area of Study 1: Enhancing fitness through training. • Fitness components and definitions • Fitness assessment including methodology, techniques and outcomes • Activity analysis – skills analysis, work-rest ratios, movement patterns, muscle groups and muscle actions • Fitness training principles – specificity, intensity, duration, frequency and overload • Fitness training methods to improve strength, speed, endurance, power, flexibility, motor skill ability.

  14. Area of Study 2: Strategies for enhancing sports performance • Chronic adaptations of the cardiovascular, respiratory and muscular systems to training • Managing a training load, including physiological and psychological factors affecting recovery and overtraining • Sports injury risk and management systems • Nutrition for improving performance, including dietary enhancement procedures • Ethical considerations in the use of legal and illegal practices employed to enhance performance and assist training and recovery.

  15. Unit 4 Outcomes • OUTCOME 1 • Students should be able to plan and evaluate training programs to enhance physical fitness. • (Area of Study One)

  16. Unit 4 Outcomes • OUTCOME 2 • Students should be able to evaluate practices and/ or strategies that are used in conjunction with each other to enhance sports performance. • (Area of Study Two)

  17. VCE PE CLASS RULES • You are to turn up to class on time. You will meet in the classroom on your timetable EVERY lesson and then move to other areas (e.g TWC). • 3 Lates = DETENTION • Normal referral rules apply – you will be referred for not having the textbook! • Parents will be notified and a meeting called if you are falling behind or not participating in class activities. • VCE handbook rules adhered to.

  18. TEXTBOOK “NELSON” Book 2 • Has chapter focus and mind maps • Checklist at the start of each chapter outlining knowledge and skills you will need to acquire. • Practice assessment tasks • End of chapter summaries • End of chapter review questions • List of useful websites each chapter • End of unit practice exam • Other textbook will be available – class set in library

  19. INTRODUCING PHYSICAL ACTIVITY INTO YOUR LIFESTYLE

  20. BRAINSTORM • What do you see are the main benefits of physical activity? • GROUPING OF BENEFITS • Social benefits • Physical and mental benefits • Environment benefits • Economic benefits • Health benefits

  21. DEFINITION : PHYSICAL ACTIVITY • Movement of large muscle groups that results in increased energy expenditure • Includes active play, sport, exercise, (organised and non-organised) • May be structured in nature or incidental

  22. DEFINITION: EXERCISE A subset of physical activities defined as: • “planned, structured and repetitive bodily movement done to improve or maintain one or more components of physical fitness”

  23. DOMAINS OF PHYSICAL ACTIVITY • Household / Gardening • Leisure-time • Occupational • Active transportation

  24. DIMENSIONS OF PHYSICAL ACTIVITY • FREQUENCY (how often) • INTENSITY (how hard) • TIME / DURATION (how long) • TYPE (kind of activity)

  25. INTENSITY • Moderate Intensity Physical Activity can be defined as activity equivalent to a brisk walking pace (3 – 5.9 METs) • Vigorous Intensity Physical Activity can be defined as activity exceeding a brisk walking pace such as jogging (6+ METs) 1 MET = Rate of energy expenditure at rest 1 MET equals 3.5ml/kg/min., which is the amount of oxygen that a person needs while at rest

  26. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS Recommended activity levels for the maintenance of a healthy lifestyle for specific categories of the population: • Adults • Children and youth • Older people • Overweight and obese people

  27. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS ADULTS Previous recommendation (prior to 1995) • Used FITT formula: • Frequency – min. 3 days per week • Intensity – 60-90% of Max HR • Time – 20 + mins each session • Type – Sustained vigorous activity involving large muscle groups

  28. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS ADULTS Current Recommendation: • 30 minutes of moderate intensity physical activity on most, if not all, days of the week (min. 5 days) (can be accumulated in 10 minute bouts) • Significant health benefits (inactive – moderately active) • Can be accumulated in any domain of life (Household / Gardening, Leisure-time, Occupational, Active transportation)

  29. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS ADULTS (continued) • Any form of movement of the body is seen an opportunity for improving health, not as a time wasting inconvenience • Make a habit of walking or cycling instead of using the car, or doing things yourself rather than using labour-saving machines

  30. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS ADULTS (continued) • Suggested additional activities: Vigorous exercise that makes you “huff and puff” - for best results, this should be added to the above recommendation on 3 – 4 days a week for 30 minutes or more each time.

  31. Why did the recommendations change? • Only 20-30 % of the population were achieving the previous recommendations • Strong evidence from epidemiological studies indicated that the greatest gains to public health were achieved by moving people from sedentary to low or moderate levels of physical activity • Accumulation of activity considered more achievable – easier to incorporate into daily life

  32. Self - Monitoring of Activity Levels PEDOMETER USE IS ALSO RECOMMENDED less than 5000 steps/day = SEDENTARY 5000 – 7499 steps/day = INACTIVE 7500 – 9999 steps/day = SOMEWHAT ACTIVE 10,000+ steps/day = ACTIVE

  33. Physical Activity Pyramid

  34. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS OLDER PEOPLE Recommendation (same as for Adults): • 30 minutes of regular moderate intensity physical activity on most days of the week (can be accumulated in 10 minute bouts) • Can be accumulated in any domain of life (Household / Gardening, Leisure-time, Occupational, Active transportation)

  35. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS OLDER PEOPLE Additional Guidelines • To reduce their risk of falls and increase mobility, strength and balance training are also recommended • Gentle exercises such as Tai Chi and everyday lifestyle physical activities such as household work. Walking and gardening can lead to improved muscle strength and balance

  36. NATIONAL PHYSICAL ACTIVITY GUIDELINES FOR AUSTRALIANS Overweight or Obese Adults • It is recommended that overweight/obese adults engage in 60 minutes of physical activity per day • Once weight has been lost it is recommended that adults accumulate 60-90 minutes of activity per day to avoid weight regain

  37. NPAG for Children • Duration – 60 minutes & up to several hours per day • Intensity – moderate to vigorous • Type – range of different types of activities including weight bearing impact-type activities important for bone strength and development.

  38. Additional guideline for children • Children and youth should NOT spend more than 2 hours per day using electronic media for entertainment (eg. TV, electronic games and internet).

  39. Data – % of children per day accumulating 60+ min MVPA / day

  40. What does this data tell us? • Work in pairs and discuss the data presented on children’s MVPA levels per day. Make two recommendations on how this could be improved.
