Lab Aerobic Field Tests

Question 1

Why do we measure cardiorespiratory fitness?

Answer 1

It reflects the functional ability of your heart, vasculature, lungs, and skeletal muscles. It is a direct assessment of your life-sustaining muscles.

Question 2

What determines cardiorespiratory fitness?

Answer 2

Fick equation (Q x AVO2 difference)

Question 3

What are the considerations before evaluating CRF?

Answer 3

• Which is most appropriate for the client
• Standard Error of the Estimate
• Time required
• Expense
• Personnel
• Equipment and facilities
• Risk level

Question 4

What are the pre-test requirements for CRF?

Answer 4

• Comfortable exercise clothes
• Avoid tobacco and caffeine 3 hours prior
• Avoid Alcohol 12 hours prior
• Hydrated and no strenuous exercise 24 hours prior
• good night’s sleep the night before

Question 5

How do the pre-test requirements alter the HR/VO2 relationship?

Answer 5

It will increase heart at any given VO2 which will underestimate their VO2 max because their heart rate would be artificially elevated causing inaccuracy and underestimation.

Question 6

What are the field test advantages when conducting CRF?

Answer 6

• Does not require highly trained personnel
• Inexpensive
• Little equipment
• Typically safe
• Easier to get a large sample size

Question 7

The Cooper Run Test consists of what exercise for its evaluation?

Answer 7

1.5 Mile run

Question 8

What are the key determinants of the quality of data that the Cooper Run Test gives?

Answer 8

It assumes the subject is MOTIVATED and understands proper PACING.

Question 9

How long for an average male and female with an average VO2 max take to complete a 1.5-mile run?

Answer 9

12 minutes for males and 14 minutes for females.

Question 10

What is the VO2max cut-off for a heart transplant?

Answer 10

An individual may be considered for a heart transplant if their VO2max is below 16ml/kg/min as this would make most ADLs feel highly intensive.

Question 11

How does CRF level relate to diseased individuals in a clinical setting?

Answer 11

Having a low level of CRF is an independent risk factor for all-cause and cardiovascular mortality.

Question 12

Based on the Queens Step Test, how is the relationship of Heart Rate and VO2max described when plotted on a graph?

Answer 12

Negative-Inverse linear relationship.
- Higher VO2 max has an implication of lower HR response at a given workload

Question 13

What populations would you prefer to use the Rockport walk test to measure VO2 max?

Answer 13

• Sedentary
• Unfit
• Those with orthopedic issues
