exercise Flashcards
what is exercise
purposeful structured muscular activity to improve physical condition
hwat is physical activity
includes all muscular activity of all intensities
what are activities of daily living
basic independent self care tasks done on a daily basis to aid in living
what is ventilation perfusion matching
for efficient gas exchange ther needs to be maximum coupling between ventilation and perfusion
what is a cardiopulmonary stress test
cycle ergometer/treadmill
incremental intensity under close clinical supervision - controlled environment
ECG, ventilation, O2/CO2 measured
outputs of cardiopulmonary exercise test
peak VO2 primarily
ECG changes
lots of data
advantages and disadvantages of cardiopulmonary exercise test
+ve - quantifies perfomance in relation to metabolism, precise, preproducible, continuous safety monitoring
-ve - skilled technical support needed, expensive, dedicated space needed
what is the six minute exercise test
20-30m flat course
cover as much distance as possible in 6 mins
externally timed by assessor - submaximal test
outputs of 6 minute exercise test
total distance walked in 6 mins
secondary - perceived exertion scales, HR, pulse oximetry
advantages and disadvantages of 6 min exercise test
+ve - patient driven pace, cheap, validated in many clinical pops.
-ve - requires significant unobstructed course, often done in public hospital corridor, pace not regulated
what is the incremental shuttle walk test
10m circuit, externally paced via recording
each min has an extra length than the last
output of incremental shuttle walk test
total distance walked before giving up
secondary - perceived exertion scales, HR, pulse oximetry
advantages and disadvantages of incremental shuttle test
+ve - cheap, validated in many clinical pop. external pacing helps achieve maximum exertion level
-ve - requires unobstructed course, public hospital corridor, incremental nature may be difficult (min speed 1.8) ceiling effect at 1020m, patient can be penalised for poor pace management
factors affecting exercise capacity
neurological (motor control/coord)
respiratory (lung ability to ventilate, pulmonary perfusion, gas exchange)
cardiovascular (ability for heart to receive blood from lungs, pump to working muscles)
muscular (local perfusion, muscle cell enzymes)
what are exercise capacity tests used for
monitor disease severity and progresion
monitor response to treamtnet
