Chapter 2 Flashcards
What is/is not physical activity?
PA - > movement that is intentional, voluntary and directed towards achieving an identifiable goal
not PA - > movements that are involuntary (reflexes), or those performed aimlessly and without purpose
Does all physical activity improve health?
Only moderate, vigorous and high intensity PH have been shown to lead to health improvements
What does it mean to be “fit”
To be considered fit, your cardiorespiratory fitness levels must reach a certain standard
What is cardiorespiratory fitness?
How well your physiological systems can transport oxygen. This is measured as Aerobic Capacity (VO2) or MET (metabolic equivalent of task).
1 MET = 3.5 ml/kg/min
What can a physically fit person do?
- > perform the essential activities of daily living at a high level
- > has sufficient energy remaining to pursue an active leisure lifestyle
- > can meet unexpected physical demands that emergencies might impose
MET Rates
FOR ADULTS
Moderate - > 3-5.9 MET’s
Vigorous - > 6+ MET’s
Why is it important to be fit
there are links between cardiorespiratory fitness and cancer mortality (increase in CF = decrease in cancer mortality)
Philosophy in relation to physical fitness
- > fitness at what cost?
- > what is your personal philosophy around physical fitness
Sociology in relation to physical fitness
- > how do we value physical fitness
- > how do the determinants of health affect your physical activity
Determinants of health
- > Income & social status
- > Employment & working conditions
- > Education & literacy
- > Childhood experiences
- > Physical environment
- > Social support & coping skills
- > un/healthy behaviours

- >
Biomechanics in relation to physical fitness
- > what is the pattern of movement of the body during a motion
- > which motions increase our risk of injury a movement
- > what are the exact strains on the joints during a movement
Exercise Physiology in relation to physical fitness
- > how much movement can you do and at what rate
- > how much force can you produce/generate
- > how much energy can you produce to sustain a movement
