Exercise tests to evaluate CR function

Question 1

What information does a ACSM health screen process give you?

Answer 1

-individuals current level of physical activity
-presence of signs/symptoms and or known metabolic CV or renal disease
-desired exercise intensity (their personal goals)
-measurement: HR, BP, serum Cholesterol, ECG if GXT is diagnostic
-PAR-Q+ is a physical activity readiness questionaire

Question 2

What is a submaximal GXT (graded exercise test)

Answer 2

-HR measurement at each stage of test from light work (<3 METs) to a predetermined end point
-treadmill, cycle ergometer or step

Question 3

What is a Maximal GXT test?

Answer 3

working to exhaustion or symptoms of angina or dyspnea
-CRF = last work rate

Question 4

what is a maximal not graded test?

Answer 4

physiological measurements made at the completion of test rather than at each stage

Question 5

Examples of maximal run tests

Answer 5

cooper’s 12 or 1.5 mile walk/run

Question 6

what are advantages of maximal run tests

Answer 6

moderately high correlation with VO2 max
-natural activity
-large numbers can perform at once
-low cost

Question 7

What are disadvantages of maximal run tests

Answer 7

-difficult to monitor physiologic responses
-motivation
-not graded but max effort

Question 8

Walk test - maximal test

Answer 8

-alternative to max run test – walk a mile as fast as you can and measure HR for only 10 seconds
-can be used to predict VO2 max
-walks 1 mile as fast as possible on a flat track
-measure HR at end and calculate VO2 max
-as fitness improves, time and HR decrease and VO2 max increases

Question 9

GXT measurements

Answer 9

-HR: shoulder be measured for only 10 seconds because it changes rapidly
-BP
-ECG: used to dx CHD, arrhythmias, ST segment changes
-RPE: indicators of subjective efforts, large variability between subjects but not within subjects

Question 10

VO2 max primary criteria

Answer 10

-standard estimate of CRF (cardiorespiratory function)
- VO2 fails to increase when workload is increased yielding a plateau in VO2
-only observed in 50% of healthy adults (that are able to reach that plate)

Question 11

VO2 Max secondary criteria

Answer 11

post exercise blood lactate concentration >8mmole/L
-R> 1.15 (respiratory exchange ratio = VCO2/VO2
-accumulate CO2 and decrease pH
-causing hyperventilation

Question 12

Where is the highest VO max reach on?

Answer 12

a treadmill running up a grade, then walking up a grade, then cycle ergometer

Question 13

VO2 max convention

Answer 13

VO2 max is measurement on a treadmill graded running test and VO2 peak describes highest VO2 achieved on a cycle or ergometer or walking

Question 14

VO2 max estimate from max work load

Answer 14

-important that test is used to determine work is best suiting for the individual (a cyclist should be on a bike)
- if increments are too large or too shot for person to achieve a steady state - equators will overestimate persons VO2 max
-used last completed stage to compute VO2 max

Question 15

VO2 max estimate from submit work

Answer 15

-based on HR response
-plot HR abasing estimated VO2 until reach 70-85% of age predicted max HR
-extrapolate to max HR

Question 16

Aerobic tests treadmill

Answer 16

-treadmill: Bruce treadmill for Max O2 consumption (stress test)

Question 17

aerobic test run/walk/jog test

Answer 17

Cooper run test,
Cooper 1.5 mile test,
Cooper 12 minute run test,
George jog test,
rockport walk test,
6 minute walk test

Question 18

aerobic test cycle ergometer

Answer 18

-cycle ergometer: astrand cycle test for sub maximal and cycle max O2 test

Question 19

aerobic test step test

Answer 19

step test: forestry step test

Question 20

GXT protocols for teadmill

Answer 20

Balke standard protocl:
-submax = 3 mph, 2.5% each 2 minutes and terminated at 85% of age predicted max HR

Question 21

GXT protocols for cycle ergometer

Answer 21

YMCA protocol

Question 22

GXT protocols for step test

Answer 22

mCAFT step test
-submax using lowest 2 8” steps
