Questions & Exam Preparation
Valid - Correct answer✅✅ When a method measures what it is intended to measure accurately
Reproducibility - Correct answer✅✅ The precision obtained when measurement results are produced
over a wider timescale by different people in different places.
reliable science - Correct answer✅✅ consists of data, hypotheses, theories, and laws that are widely
accepted by scientists who are considered experts in the field under study.
Biochemical test for folate - Correct answer✅✅ Erythrocyte levels
dual energy x-ray absorptiometry (DEXA) - Correct answer✅✅ 3 compartment model for assessment
of body composition
Primary purpose of surveys - Correct answer✅✅ To determine the overall nutritional status of the
population
Australian PA guideline (1)(adults) - Correct answer✅✅ Doing any PA is better than none. if you
currently do no PA, start by doing some and gradually build up to the recommended amount
Australian PA guideline (2)(adults) - Correct answer✅✅ - Be active on most, preferably al, days every
week
- for at least 30 mins, can be made up of 10 min increments
Aus PA guideline (3) (adults) - Correct answer✅✅ Accumulate 150-300 mins of mod intensity PA or 75-
150 mins of vigorous intensity PA or an equivalent combination of both moderate and vigorous
activities, each week.
,Aus PA guideline (4) (adults) - Correct answer✅✅ Do muscle strengthening activities on at least 2 days
of each week
Aus PA guidelines for sedentry behaviour (adults) - Correct answer✅✅ - min. the amount of time
spent in prolonged sitting
- break up long periods of sitting as often as possible
PA guidelines (1) (children and young people) - Correct answer✅✅ For health benefits, children aged
5-12 should accumulate at least 60 mins of moderate to vigorous intensity PA each day
PA guidelines (2) (children and young people) - Correct answer✅✅ Children's PA should include a
variety of aerobic activities including some vigorous intensity activity
PA guidelines (3) (children and young people) - Correct answer✅✅ on at least 3 days per week
children should engage in activities that strengthen muscle and bone
PA guidelines (4) (children and young people) - Correct answer✅✅ to additional health benefits
children should engage in more activity - up to several hours
PA guidelines older adults - Correct answer✅✅ Older adults should do some form of PA, no matter
what their age, weight, health problems or abilities

recommended amount, type and frequency
, PA guidelines older adults (5) - Correct answer✅✅ Older people who continue to enjoy a lifetime of
vigorous PA should carry on doing so in a manner suited to their capability in later life, provided
recommended safety procedures and guidelines are adhered to
Domains of PA - Correct answer✅✅ - household
- occupation
- leisure time
- transport
Dimensions of PA - Correct answer✅✅ F (frequency - # sessions per week/day)
I (intensity - rate of EE)
T (time - hours/min/day/week)
T (type - walking, cycling)
PA and dose response - Correct answer✅✅ PA that yields an EE of 800-1000 kcal/week is associated
with a 20-30% reduction in risk of all cause mortality
