Q

relative risk

A

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.

Q

objective studies: what reduces risk

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

17
Q

aging body

A
  • adults 70-79
  • hand grip testing
  • isokinetic testing (quads)
  • body composition (DEXA)
  • thigh muscle area
18
Q

aging body results

A
  • as strength decreases risk of mortality increased

- may be independent from cardio respiratory fitness

19
Q

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

A

20% lower

20
Q

diabetes with what causes what

A

low CRF had 4.5% greater risk of all cause mortality

21
Q

metabolic syndrome

A

-cardiorespritory fitness lowers mortality

22
Q

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

A

50-70%

23
Q

what % is the reduction in risk to cause mortality

A

30% reduction

24
Q

sedentary, low fitness individuals who are classified as obese are

A

high risk group

25
Q

low fitness may be a

A

better indicator of consequences of inactive lifestyle

26
Q

cardiovascular disease

A

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

27
Q

coronary heart disease

A

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

28
Q

stroke

A

disease that affects the arteries leading to and within the brain

29
Q

hypertension

A

abnormally high blood pressure

30
Q

peripheral vascular disease

A

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

31
Q

lung disease

A

chronic obstructive pulmonary disease

-asthma

32
Q

CHD, stroke and PVD

A
  • decrease blood pressure
  • better blood lipid profile
  • decrease systemic inflammation
  • blood vessels are healthier
33
Q

hypertension

A

-meta-analysis: 24% reduction developing hypertension

34
Q

how to reduce hypertension

A

peripheral resistance

35
Q

peripheral vascular disease

A
  • unclear if indirect or causal

- physical activity will not hurt

36
Q

lung disease

A
  • amount of research much smaller

- cause or effect

37
Q

asthma

A

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

38
Q

physical activity and patients need to be monitored by

A
  • health professional

- usually safe

39
Q

physical activity reduces

A
  • functional status declines
  • social isolation
  • depression
40
Q

Absolute intensity

A

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

41
Q

relative intensity

A

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