Assessing aerobic fitness

Question 1

What are the 4 energy pathways in the body?

Answer 1

Anaerobic alactic (ATP PCR)
Anaerobic lactic (Glycolysis)
Aerobic (krebs cycle)
Aerobic (ETC)

Question 2

What are the two energy sources during aerobic exercise?

Answer 2

Fat and carbohydrates

Question 3

Where is the fat stored that is used by skeletal muscle during exercise?

Answer 3

FFA in the blood

Stored triglycerides in muscle (lipolysis)

Question 4

What are we measuring when we measure aerobic fitness?

Answer 4

The ability to consume oxygen (VO2) to perform exercise

The ability to consume oxygen to perform MAXIMAL exercise (vo2max)

Question 5

Def: Absolute and Relative VO2

Answer 5

Absolute VO2 - total volume of O2 taken into the body (L/min or mL/min
Relative VO2 - volume of vo2 relative to body weight (ml/kg/min)

Question 6

When would you conduct a submax vo2 test instead of maximal?

Answer 6

Client ability
Reasons for the test - if not for performance most likely dont need to do maximal
Risk level of client
Availability of equipment/personnel

Question 7

What are the benefits of conducting a maximal aerobic fitness test?

Answer 7

Classify aerobic fitness of client
More accurate data to use for exercise prescription

Question 8

What is the difference between direct and indirect VO2max test?

Answer 8

Direct - using metabolic cart
Indirect - measuring vo2max with equations - still done with maximal effort
