Question 1

what is CRF

Answer 1

the ability to perform large muscle, dynamic, moderate to vigorous intensity exercise for prolonged periods of time

Question 2

gold standard for measuring CRF

Answer 2

max volume of O2 consumed per unit time = VO2 max
-measured in ml/kg/min (relative) or L/min (absolute)

Question 3

how do you calculate HR max for healthy men and women

Answer 3

HR max= 208 - (0.7 x age)

Question 4

how do you calculate HRmax for men and women in adult fitness programs with broad range of age and fitness levels

Answer 4

HRmax= 207 - (0.7 x age)

Question 5

maximal exercise test

Answer 5

exercising until you hit volitional fatigue

Question 6

submaximal exercise test

Answer 6

client exercises to 85% or less of max HR

Question 7

how do we decide whether to use maximal or submaximal

Answer 7

-reasons for test
-risk level of client
-availability of appropriate equipment and personnel
-appropriateness of working some individuals to point of volitional fatigue

Question 8

assumptions we make when estimating VO2max

Answer 8

-steady state HR
-HR and work rate are a linear relationship
-predicted max HR is accurate
-mechanical efficiencies same for everyone
-not on meds that alter HR response to exercise
-not using high quantities of caffeine or in high temp environment

Question 9

whats a field test

Answer 9

measuring post exercise HR
-running, walking, stepping, cycling, swimming

Question 10

examples of a field test

Answer 10

6 min walk test
1.5 mile walk/run test
20m beep test

Question 11

if patient is taking beta blockers, whats the formula for HRmax

Answer 11

HRmax= 164 - (0.7xage)

Question 12

bruce protocol treadmill tests

Answer 12

3 min stages, increasing speed and grade each time
