Chapter 10

Question 1

body mass index

Answer 1

• kg/m2

- health indicator because accounts for height

Question 2

what is a good BMI

Answer 2

under 25

Question 3

what does BMI not take into account

Answer 3

muscle (lean muscle vs fatty tissue)

Question 4

how could your BMI be wrong

Answer 4

you could have alot of lean muscle mass which would make your BMI higher, making you seem overweight

Question 5

mortality from

Answer 5

• all causes
• cardiovascular disease
• cancers

Question 6

relative risk

Answer 6

the ratio of the probability of an event occurring (for example, developing a disease, being injured) in an exposed group to the probability of the event occurring in a comparison, non-exposed group.

Question 7

work related to PA: mortality rates from CVD is

Answer 7

50% lower

Question 8

leisure time PA:CVD and all cause

Answer 8

reduced

Question 9

objective studies: what reduces risk

Answer 9

• energy expenditure & cardiovascular and muscular fitness
• increase by 287kval/day = 30% lower risk mortality

Question 10

moderately fit

Answer 10

about 1/2 risk all cause mortality

Question 11

highly fit

Answer 11

additional 10-15% benefit

Question 12

physical activity can reduce mortality risk by

Answer 12

20-30%

Question 13

does intensity matter

Answer 13

1. relative intensity

2. energy expenditure

Question 14

moderate and high fitness group

Answer 14

37% lower in men

48% lower in women

Question 15

muscular fitness

Answer 15

• grip strength

- inverse relationship = higher strength =lower mortality

Question 16

aerobics center longitudinal study

Answer 16

-men 20 to 80 years
-bench and leg press
relative risk

Question 17

aging body

Answer 17

• adults 70-79
• hand grip testing
• isokinetic testing (quads)
• body composition (DEXA)
• thigh muscle area

Question 18

aging body results

Answer 18

• as strength decreases risk of mortality increased

- may be independent from cardio respiratory fitness

Question 19

obesity- if active at level of PA guidelines the risk is

Answer 19

20% lower

Question 20

diabetes with what causes what

Answer 20

low CRF had 4.5% greater risk of all cause mortality

Question 21

metabolic syndrome

Answer 21

-cardiorespritory fitness lowers mortality

Question 22

what % is mortality lowered from CVD when you do cardiorespritory fitness

Answer 22

50-70%

Question 23

what % is the reduction in risk to cause mortality

Answer 23

30% reduction

Question 24

sedentary, low fitness individuals who are classified as obese are

Answer 24

high risk group

Question 25

low fitness may be a

Answer 25

better indicator of consequences of inactive lifestyle

Question 26

cardiovascular disease

Answer 26

Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke

Question 27

coronary heart disease

Answer 27

Coronary heart disease (CHD) is when your coronary arteries (the arteries that supply your heart muscle with oxygen-rich blood) become narrowed by a gradual build-up of fatty material within their walls

Question 28

stroke

Answer 28

disease that affects the arteries leading to and within the brain

Question 29

hypertension

Answer 29

abnormally high blood pressure

Question 30

peripheral vascular disease

Answer 30

circulatory problem in which narrowed arteries reduce blood flow to your limbs

Question 31

lung disease

Answer 31

chronic obstructive pulmonary disease | -asthma

Question 32

CHD, stroke and PVD

Answer 32

- decrease blood pressure - better blood lipid profile - decrease systemic inflammation - blood vessels are healthier

Question 33

hypertension

Answer 33

-meta-analysis: 24% reduction developing hypertension

Question 34

how to reduce hypertension

Answer 34

peripheral resistance

Question 35

peripheral vascular disease

Answer 35

- unclear if indirect or causal | - physical activity will not hurt

Question 36

lung disease

Answer 36

- amount of research much smaller | - cause or effect

Question 37

asthma

Answer 37

-influence lung during development-better lung capacity- smaller chance of bringing on symptoms

Question 38

physical activity and patients need to be monitored by

Answer 38

- health professional | - usually safe

Question 39

physical activity reduces

Answer 39

- functional status declines - social isolation - depression

Question 40

Absolute intensity

Answer 40

is a general measurement of intensity applied to anyone, independent of any factors. It is usually measured as a metabolic equivalent, or MET

Question 41

relative intensity

Answer 41

Relative exercise intensity is specific to your level of fitness. A relative exercise intensity is based off of your own maximum capability of work
