Exercise Testing Guidelines Flashcards
Contraindication for exercise testing
Resting SBP?
Resting DBP?
SBP > 200mmHg
DBP > 110mmHg
Contraindication for exercise testing
acute systemic fever temperature?
above 102
Contraindication for exercise testing
uncontrolled sinus tachycardia
> 120bpm
Contraindication for exercise testing
uncontrolled diabetes
resting blood glucose >400
Normal exercise response
heart rate
increases linearly
Normal exercise response stroke volume (how many ml/beat, what kind of curve?)
60-100ml/beat
curvilinearly
Normal exercise response cardiac output (how many L per beat, what kind of curve?)
5L/min starting to 20L/min w/ upright exercise
linear
Normal exercise response
rate pressure product
increases with increasing work rate
Normal exercise response
arteriovenous-oxygen difference
reflects ability of skeletal m. to extract oxygen
Normal exercise response
maximum oxygen consumption (conditioned vs non-conditioned person)
10-fold raise for unconditioned person
23 fold raise for conditioned person
Normal exercise response
blood pressure SBP and DBP
SBP - increase linearly
DBP - remain constant or slightly decrease
anaerobic threshold adaptation to training
increased ability to buffer and to tolerate lactate
Abnormal response to exercise
heart rate
no linear increase in HR
Abnormal response to exercise
stroke volume
impaired or depressed stroke volume
Abnormal response to exercise
cardiac output
failure of CO to increase linearly with workrate
Abnormal response to exercise
rate pressure product
does not increase with increasing work rate
myocardial ischemia
Abnormal response to exercise
arteriovenous-oxygen difference
impaired ability for muscle to extract oxygen
Abnormal response to exercise
maximum oxygen consumption
inability to increase oxygen transport with increasing energy demands
Abnormal response to exercise
blood pressure SBP & DBP
sudden sharp rise in SBP or lack of increase
DBP increases or drops sharply
Adaptation to training
heart rate
lower resting heart rate
max heart rate same or slightly lower
Adaptation to training
stroke volume
stroke volume and ejection fraction both increase
Adaptation to training
cardiac output
CO at max training increases
Adaptation to training
rate pressure product
resting RPP decreases over time
Adaptation to training
arteriovenous-oxygen difference
increase in exercise tolerance
Adaptation to training
maximum oxygen conspumption
VO2 max increases
Adaptation to training
blood pressure
in ppl without HTN SBP should remain the same after training
