Chapter 1 - NPAG & Assessment of PA Flashcards
What are the 4 dimensions of PA?
Frequency
Intensity
Duration
Type
What are the 4 domains of PA?
Household & Gardening
Leisure Time
Occupational
Active Transport
What is a MET and what does it stand for?
Metabolic Equivalent
Used to measure the amount of oxygen used by the during physical activity.
How many METS for rest, low, moderate and vigorous activity.
Rest: 1
Low: 1-3 METS
Moderate: 3-6
Vigorous: 6+ (7+?)
What is PA and how is it different to exercise?
Physical activity is the movement of large muscles to increase energy expenditure and can be structures or unstructured.
Exercise falls under the umbrella of PA but is done to improve or maintain fitness components rather than health.
Types of Benefits of PA?
Health Economic Social Mental Environmental
What are some health benefits of PA?
Decreased risk of: Cardiovascular disease Stroke Type II diabetes Colon cancer Osteoporosis Lowers: Blood cholesterol Hypertension (high blood pressure)
Mental benefits of PA.
Sleep
Concentration
Memory and Learning
Social benefits of PA?
Social networks
Increased self esteem
Economic benefits of PA.
Employment through sporting events.
Health savings
Reduces absenteeism
Environmental benefits of PA.
Reduces:
Traffic congestion
Air pollution
Noise pollution
What are some reasons for studying PA?
Document frequency and distribution of PA levels with population groups.
Study relationship between PA and health benefits
Identify factors that influence PA.
Evaluate effectiveness of interventions
Objective Vs subjective measurements
Objective rely on quantitative data while subjective relys on information subject to ones memory or bias.
Advantages of Pedometers
Cheap
Non-invasive
Increases awareness of PA and can lead to behavioural change.
Disadvantages of pedometers
Assesses only walking/running
Does not provide any info on the dimensions of PA undertaken (intensity/duration/frequency/type). (Cannot determine if NPAG is met.)
Can be reactive
No contextual data
Estimates of energy expenditure are based on adults.
