T or F Reduced physical activity and increased fat mass with age may account for as much as 50% of the “age related” decline in (VO2) men and women.”

Answer 15

True

Question 16

Social Security Administration uses the criteria that ____ mets is considered disabled.

Answer 16

<5 or 3.5x5= 17.5 vo2 max

For persons with CAD, risk of complication such as MI or death is __ to ___ times greater during exercise testing then during usual activity

Answer 17

60 to 100 times greater

Question 18

T or F. Actual risk of death during exercise testing is very High for CAD patients?

Answer 18

False, it is a low risk due to appropriate screening and adherence to established methods of conducting the tests

Question 19

What is the Standardized Procedures
for sub max testing?

Answer 19

1) Explanation of procedure
2) Avoid maximal activity for 24 hours prior
3) Avoid for 2-3 hours prior ◦large meal
◦ Nicotine ◦ Caffeine
4) Repeat submax test

Question 20

Is the Following an Endurance Test?
65 y/o female with a history of moderate to severe COPD
◦ If you take resting HR, BP, RPE, and RR ◦ Have her ambulate down the hall 100 feet ◦ Time how long this takes
◦ And record post HR, BP, RPE, and RR
◦ Is this an endurance test?

Answer 20

Yes

Question 21

General Guidelines for submit test?

Answer 21

• Warm-up: 2-3 min
• Measure HR, BP, RPE at regular intervals
  ◦ End of each stage [HR, BP, RPE] or every minute [HR]
  ◦ If HR does not reach steady state during the stage, then extend
  stage 1 minute
• Increase intensity in 0.5 to 2 MET increments
• Closely observe subject for signs/symptoms
• Cool-down: low intensity for ≥4 min
  ◦ Continue measuring HR, BP and RPE

Question 22

it has been suggested that submaximal exercise testing underestimates VO2 Max in the ________ and ________ in the trained.

Answer 22

Underestimates for untrained, overestimates for trained.

Question 23

5 Submax Test Assumptions?

Answer 23

1. A steady-state HR is obtained for each exercise work rate
2. A maximal HR for a given age is uniform (220 –age)
3. Mechanical efficiency (i.e., VO2 at a given work rate) is the
   same for everyone.
4. There is a linear relationship between HR and workload.
5. HR will vary depending on fitness level between subjects at any given workload.

Question 24

Advantages of Submax Testing?

Answer 24

1. Safer
2. Controlled pace (motivation not a factor)
3. Not population specific (no pacing advantage)
4. Quick assessment
5. Costeffective
6. Do not need highly trained personnel
7. Can do mass testing
8. No physician supervision required (if symptom and disease free)

Question 25

Disadvantages of Submax Testing?

Answer 25

1. VO2 max is not directly measured ◦ Error rate of 10-20%
2. Not a measure of true maximal HR
   ◦ Estimates of max HR using 220-age can vary by +15 BPM for individuals of the same age

Question 26

Advantages of max testing?

Answer 26

accuracy

Question 27

what are disadvantages to Max testing?

Answer 27

• Health risk * Time
• Expense (metabolic cart)
• Personnel (MD supervision)
