1

What is physical activity?

not sedentary behavior, bodily movement

2

What is exercise?

a planned and structured physical behavior

3

What is fitness?

an attribute resulting from regular exercise

4

What is disease?

abnormal or loss of function of cells + organ systems of the body

5

What is health?

complete state of mental, physical, and social well-being

6

Whats the difference between medicine and public health?

medicine treats individuals, public health prevents populations

7

What is mortality?

death

8

What is morbidity?

the rate of incidence of a particular disease

9

What is epidemiology?

study of patterns of health and disease in a population

10

What is incidence?

a new occurrence of an outcome

11

What is prevalence?

function of incidence and duration

12

How do you calculate incidence/prevalence rate?

number of cases/average population size

13

What is relative risk?

ratio of the probability of the event occurring in the exposed group vs. a non-exposed group

14

How do you calculate relative risk?

Subtract by 1 and then the decimal is the percentage

15

What is measuring physical activity important?

determine levels of PA in populations and how they change, to implement programs to increase PA, to figure out what parts of PA are important to health

16

What is energy expenditure important to get activity levels?

to understand the requirements for rest and exercise

17

What is energy expenditure?

amount of energy a person uses daily to complete all activities

18

What are the 3 things that determine total daily energy expenditure?

thermic effect of feeding and physical activity, and resting metabolic rate

19

What are things that influence resting metabolic rate?

body surface area, growth, genre, stress, age, thyroid

20

What does direct calorimetry measure?

body heat loss

21

What does indirect calorimetry measure?

O2 consumption

22

What does doubly-ladled water measure?

free-living metabolic rate

23

What is the gold standard for measuring resting metabolic rate?

doubly labeled water

24

What's the biggest weakness of doubly labeled water?

EXPENSIVE!

25

What are METs?

energy expenditure at rest/resting metabolic rate

26

What are the two things directly related with METs?

oxygen consumption and energy expenditure

27

How many METs are considered light intensity?

1.1-2.9 METs

28

How many METs are considered moderate intensity?

3-6 METs

29

How many METs are considered vigorous intensity?

6.1-9 METs

30

How many METs are considered vigorous intensity?

greater than 9 METs
