AOS2- Physical Activity Concepts And Health Outcomes Flashcards
What are the four dimensions of physical activity?
- activity type
- frequency
- intensity
- duration
Define sedentary behaviour…
Sedentary means staying in the same place for much of the time and expending low amounts of energy. Eg. Watching tv, sitting in a car, etc…
Define cardiovascular disease…
- the biggest killer in Australia
- high physical activity levels are associated with reduction in coronary heart disease risk
- it refers to diseases of the heart or blood vessels
Define physical activity…
The movement of large muscle groups that results in energy expenditure; includes active play, sport, exercise, organised and non organised activities, walking and cycling.
What’s the difference between sport and play?
Sport is participating in organised games or activities within an accepted set of rules while play is amusing oneself in a light-hearted way with a recreation, game or exercise
What is the difference between structural and incidental physical activity?
Structured physical activity is physical activity that has been planned while incidental physical activity is less structured, for example, using the stairs instead of the lift at a shopping centre.
Define inactivity
Physical inactivity is defined as people undertaking ‘insufficient’ physical activity to achieve measurable health outcomes.
What does the ‘leisure-time activity domain’ refer to??
Leisure-time activity Is considered activity that is over and above that which occurs within the workplace. Eg. Golf, tennis, walking the dog
What does the ‘household/gardening domain’ refer to??
The activities you carry out around the house and gardens. Eg. Mowing the lawn, vacuuming, etc.
What does the ‘occupational domain’ refer to??
The physical activity performed regularly as part of ones work or occupation. Eg. Sweeping, lifting, digging (tradies).
What does the ‘active transport domain’ refer to??
Active transport is physical activity performed while traveling to a specific location (such as school, work, shop), usually across a reasonable distance by walking, cycling, skating, etc.
What does the dimension, ‘activity type’ refer to?
The type of activity that is being performed, eg. Aerobic, flexibility, strength, etc…
What does the dimension, ‘frequency’
refer to?
The number of times a person engages in physical activity within a given time frame…
What does the dimension, ‘intensity’ refer to??
The intensity of an activity refers to how much effort is required to engage in an activity. (METs)
What is a MET?
Metabolic equivalent
1 MET represents resting energy expenditure, or about 3.5ml/(kg/min) in terms of oxygen consumption
What are the benefits of physical activity?
- improved cardiovascular function
- improved strength and endurance
- resistance to fatigue
- greater lean body mass and less body fat
- improved flexibility
Explain the social benefits of physical activity…
- increases a persons sense of connectedness within the community
- improved self concept
- better quality of life
Explain the mental benefits of physical activity…
- Greater self esteem
- lower levels of anxiety
- improved the quality of sleep
- improved brain function
- lower risk of suffering from dementia and depression
What is the link between inactivity and health risks??
- for every 1 percent increase in physical activity levels, 122 deaths from CVD, diabetes and colon cancer could be avoided.
- sedentary death syndrome occurs from being sedentary
What is type 2 diabetes?
What is its role in relation to physical activity/inactivity?
Results from too much sugar in the blood, which occurs because the body either doesn’t produce or properly use insulin.
Physical activity helps prevent the onset of type 2 diabetes
What is type obesity?
What is its role in relation to physical activity/inactivity?
The state of being grossly fat or overweight.
Physical activity will act as a preventative factor to obesity
What is type hypertension?
What is its role in relation to physical activity/inactivity?
Hypertension is the medical term for high blood pressure.
It is treated by regular moderate levels of physical activity and a better diet with less salt intake.
What are the four domains of physical activity?
- leisure-time activity domain
- household/gardening domain
- occupational domain
- active transport domain
How many mets are used while... Sitting? Walking? Jogging? Running? Sprinting?
Sitting = 1MET (sedentary) Walking = 3METs (moderate) Jogging = 6METs (moderate) Running = 8METs (vigorous) Sprinting = 10-12 METs (highly vigorous)
What are the A PA & SB guidelines for 13-17 year olds??
PA GUIDELINES:
- at least 60 mins of med-big PA/day
- a variety of ears if activities including some big intensity
- at least 3 days/week of muscle strengthening
- to achieve better results, do more
SB GUIDELINES:
- reduce the amount if media technology use
- break up long sitting periods
What are the A PA & SB guidelines for 18-64 year olds??
PA GUIDELINES:
- if your not doing any PA, start doing some and slowly build up
-be active on most, preferably all, days of the week
- accumulate 150-300 mins of mod intensity PA
or
75-150 mins of vig intensity PA
- at least 2 days/week of strength activities
SB GUIDELINES:
-
