Lecture 3: Cardiorespiratory Fitness & Health

Question 1

What is the relationship between CRF and health outcomes?

Answer 1

Negative Inverse Dose Relationship

Question 2

Is fitness associated with disease independent of common risk factors?

Answer 2

Yes

Question 3

Are measures of CRF associated with morbidity and mortality independent of commonly obtained risk factors?

Answer 3

Yes

Question 4

Can CRF be measured in clinical settings pragmatically?

Answer 4

Yes, pragmatically but only as an estimation as true measurement will not be available in our lifetime

Question 5

What are ways CRF is measured in labs directly?

Answer 5

• Graded treadmill

- Cycle tests

Question 6

Can measures of CRF be improved with exercise consistent with consensus guidelines? If so, what are the guidelines?

Answer 6

Yes, Moderate to vigorous aerobic physical activities of at least 150 mins per week

Question 7

Does measurement of CRF help practitioners manage their patients/clients health risk?

Answer 7

Yes

Question 8

What is the 1 MET difference in CVD?

Answer 8

Around 15%

Question 9

T/F: Higher the fitness level the lower the risk of CVD mortality independent of risk factors

Answer 9

True

Question 10

What researchers to do evaluate/summarize a lot of prospective cohort studies

Answer 10

Meta-analysis

Question 11

What is a MET?

Answer 11

• One metabolic equivalent
• The amount of oxygen consumed while sitting at rest
  Is equal to 3.5 ml O2 per kg body weight x min

Question 12

Your risk of developing the disease over a time period

Answer 12

Absolute Risk

Question 13

Used to compare the risk in two different groups of people

Answer 13

Relative Risk

Question 14

Describe the dose-response relationship between exercise and improvements in CRF

Answer 14

Higher fitness levels means higher CRF
