Question 2

procedure and measurements for the 6min walk test

Answer 2

1. repeat testing should be at same time of day
2. NO warm up
3. client should sit in chair near start of test for 10mins
4. take vital measurements
5. rate baseline rpe
6. use lap counter and timer for 6 mins and move to starting point
7. walk as far as possible for 6 mins
8. stand near the stating line during the test - do not walk w the client
9. dont talk during the test
10. post-test record the post-walk borg ad fatigue levels
11. measure SpO2 heart rate and blood pressure
12. record laps and additional distance covered

Question 3

sub-max cycle erg test procedure (astrand-rhyming)

Answer 3

1. provide overview
2. client should have comfortable clothes, hydrated, no alc+tobacco+caffeine within 3 hours, avoid strenuous exercise day of, good sleep
3. explain borg
4. should sit for 5 mins - then measure vitals
5. adjust bike
6. perform baseline measures on the bike (in posture of exercise)
7. have them freewheel w/o resistance at 50rpm (maintain 50rpm throughout the test is essential)
8. set first stage work output then start clock
9. measure HR at each minute
10. measure BP after 3 min
11. 5th and 6th min HR is used to calc VO2 max as long as there is not more than a 6 beat difference
12. cool down
13. take recovery vitals
14. calculate vo2 max using nomogram chart

Question 4

SSTWT procedure

Answer 4

1. informed consent
2. explain borg
3. sit in chair for 5 mins to get resting vitals
4. determine walking speed
5. estimate clients age-predicted target HR and
6. have client stand on the treadmill and attach safety device
7. perform baseline measures in posture of exercise
8. start the test
9. measure vitals at end of 4 min warm up
10. increase to 5% grade and maintain speed for 4 mins
11. measure HR at the end of each minute used for VO2 max
12. cool down at 0% grade
13. 3 min active recovery vitals
14. 3 minute passive recovery vitals
15. determine predicted VO2 max

Question 5

Answer 5

• angina-like symptoms
• drop in SBP of >10
• excessive risk in BP
• shortness of breath, wheezing, leg cramps, claudication
• signs of perfusion (light head, confusion ect)
• failure of HR to increase
• change in heart rhythm
• SpO2 <80%
• client requesting to stop
• physical or verbal manifestations of severe fatigue
• failure of testing equipment
