Exercise Testing Flashcards
No regular exercise
NO Disease and No Signs and symptoms
medical clearance not necessary
No regular exercise
known disease and asymptomatic
medical clearance recommended
no regular exercise
S&S suggestive of disease
medical clearance recommended
ACSM guidelines for light intensity
30-39% HRR or VO2R
RPE 9-11
slight increase in HR and breathing
ACSM guidelines for Moderate Exercise
40-59% HRR, RPE 12-13
noticeable increase in HR and breathing
ACSM guidelines for Vigorous Exercise
> 60% HRR RPE>14
substantial increases in HR and breathing
Participates in regular exercise
NO disease & NO S&S
no medical clearance required
Known Disease but asymptomatic
no medical clearance necessary for moderate intensity recommended for vigorous
any S&S of Disease
discontinue exercise and seek medical clearance
absolute contraindication
no exercise should not be performed until their condition is stabilized
relative contraindications
patients may be tested only after evaluation of the risk/benefit ratio
signs and symptoms for ending an exercise test
fatigue. lightheadness, confusion, ataxia, pallor, cyanosis, severe dyspnea, nausea, onset of angina
test termination CV signs
fall in BP below resting levels
excessive hypotension (>20 mmhg drop in systolic)
excessive BP increase (>220 & >110 mmhg
inappropriate bradycardia
define a predictive test
sub maximal test used to predict maximal aerobic capacity
define a performance test
involve measuring the responses to standardized physical activities that are typically encountering in everyday life
assumptions of predictive tests
assumes steady stay HR at each exercise intensity
assumes linear relationship between HR VO2 & work
assumes the mechanical efficiency during cycling and treadmill
assumes maximal HR
advantages of astrand rhyming cycle test
most frequently used submax cycle test
uses HR which is easy to measure
disadvantages of astrand ryhming cycle test
can have a large margin of error in predicted VO2 max
influenced by variability in max HR
influenced by variability in max HR
Cycling can cause lower-extremity discomfort in some individuals
advantages of sub max treadmill walking test
suitable for testing people in clinical and research settings
disadvantages of sub max treadmill walking test
further research needed to validate the test in people with various disease in older adults
limited data on sensitivity to detect changes
12 min run test advantages
no specialized equipment
allows more than one person to be tested at a time
good for those with high level of functioning but may not be appropriate for a rehab setting
12 min run test disadvantages
developed using a male pop
pacing can be challenging
wording of test could make it maximal test
doesnt account for body weight
20 M shuttle test advantages
lots of stages = wide range of fitness levels to be tested
requires little equipment and multiple people can be tested simultaneously
20 M shuttle test disadvantages
frequent stopping, starting and pivoting may not be suitable for everyone
pacing might be difficult for some
testing criteria needed to ensure that the test is sub-maximal
1 mile walk test (rock port fitness test) advantages
applicable to wide range of individuals
requires little specialized equipment
uses familiar activity
suitable for rehab settings
1 mile walk test disadvantages
limited data on clinical pop
specific facilities required
assistant required
modified bruce treadmill test advantages
widely used and lots of normative data
can be used to measure ECG cardiopulmonary parameters
modified bruce treadmill test disadvantages
treadmill safety
requires special training if measuring ECG
self-paced walking advantages
appropriate for individuals requiring mobility devices or when a treadmill or cycle ergometer
suitable for monitoring an older persons mobility status over time
can identify individuals at risk for injury when crossing an intersection
self-paced walking disadvantages
does not provide a measure of endurance
may not be sensitive for those with a higher level of function
may be to difficult to compete all trials with only 5 min recovery
incremental shuffle walking test advantages
simple, audio signal standardizes increments
initial speed is slow which is accommodate
bag and carry test advantages
designed to integrate endurance, muscle force and balance capability- mimics an everyday activity
bag and carry test disadvantages
guidelines for administering the test are not well described
no specifications on height of steps, use of handrail or whether a practice trial is required
harvard step test advantages
simple test with minimal equipment requirements
can be conducted almost anywhere
harvard step disadvantages
may not be safe for some clinical populations
fixed step height
6 min walk test advantages
simple and inexpensive
corresponds well to functional activities
can be administered to healthy individuals and those with disease
using standard time rather than distance may provide better test of endurance
individual can set their own pace
highly used tested and validated
6 min walk test disadvantages
despite the guidelines, investigators use slightly different protocols
difficult to monitor HR and other physiological parameters
