Q

advantage of doubly-labeled water

A

very accurate measure of energy expenditure (measure CO2 production) can more easily simulate real world situations

Q

what is in a health appraisal

A

identify possible medical problems characteristics that increase risk of health problems signs or symptoms indicative of health problems lifestyle behaviors related to positive or negative health fitness test results

Q

disadvantages of heart rate measuring

A

not an actual measure of energy expenditure must be recorded very often fluctuates based upon many factors such as mood, eating, stress, etc

Q

what are the advantages of direct calorimetry

A

single best measure of energy expenditure b/c it measures heat production very accurate

Q

disadvantages of self report

A

must rely on subjects to remember activities and be truthful difficult to assess intensity of activity need different questionnaires for different groups of people

16
Q

disadvantage of doubly-labeled water

A

very expensive have to closely monitor water/fluid intake must track subjects closely for 1 to 2 weeks and collect urine

17
Q

what defines high risk

A

one or more sigs or symptoms or with known CVD, pulmonary, or metabolic disease

18
Q

how do we screen for increased risk

A

obtain medical history perform a risk assessment/ appraisal

19
Q

disadvantages of direct calorimetry

A

very expensive difficult to simulate real world conditions so it may not be generalizable

20
Q

in fitness testing, what measurements are taken at rest

A

HR BP percent body fat waist circumference low back flexibility

21
Q

disadvantages of movement sensors

A

difficult to assess intensity of activity false positives low validity

22
Q

moderate risk can do what kind of exercise

A

moderate intensity

23
Q

what are some health status evaluation categories

A

MR.Please medical history risk factor assessment prescribed medications level of physical activity establish need for physician consent administer and eval fitness tests set up exercise prescription eval progress with follow up tests

24
Q

advantage of heart rate measuring

A

strong relationship between HR and energy expenditure during steady state exercise with large muscle groups relatively inexpensive can be monitored during normal activites

25
advantage of indirect calorimetry
accurate measure of energy expenditure (measures CO2 production)
26
advantage of movement sensors
quantify body movement acceptable correlation to energy expenditure inexpensive good for real world monitoring
27
what measurements are taken during exercise
HR BP rating of perceived exertion VO2
28
history of PAR-Q
developed in canada 1970 revised in 1994 should contact DR if one or more yes
29
what must be in a screening questionnaire
valid provide relevant and accurate info
30
what are the three major chronic diseases we screen for
CVD pulmonary disease metabolic disease (diabetes)
31
intense exercise can lead to
sudden cardiac arrest myocardial infarction possibly due to silent CVD
32
which measures should be used when measuring physical activity
validity cost time ease of use target population
33
disadvantage of indirect calorimetry
very expensive cumbersome to use difficult to simulate real world conditions does not measure calories, less validity
34
what is a self report
questionnaires, daily activity diaries, recall interview
35
low risk can do what kind of activity
vigorous intensity
36
what defines low risk
men \< 45 women \< 55 asymptomatic and one or fewer CVD risk factors
37
what should be considered when creating an exercise prescription
individuals health status fitness test results personal goals
38
what must we identify before screening participant
increased risk
39
why has natural selection changed and are these changes good or bad for the future
inherent bias who knows
