cardiorespiratory fitness assessment and training methods Flashcards
CRF greatly influences
lifespan and quality of life
VO2 max
maximal quantity of oxygen one can use to perform work
aerobic exercise develops CRF via
adaptations that promote the efficiency of the heart, lungs, and vascular system
CRF test selection should be based on
the clients proficiency, goals, experience, specific needs
sub maximal tests are far more common than GXT due to
ease, safety, required equipment
submaximal tests
protocols do not reach the maximal capacity of the client
submaximal test maximal predictions are made using
physiological responses to the sub maximal workload based on HR response
graded exercise test
allows for more direct measurement of cardiorespiratory fitness via periodic increases in intensity to achieve a maximal or sub maximal workload
step tests are easy to implement
using limited equipment
step tests are valid for
general population, often over-predicted fit individuals
step tests are unsuitable for
moderate to high-level obese or very deconditioned clients
revenant factors of step tests
leg strength, rhythm
walk/jog tests are viable for
deconditioned or new exercisers with no experience
walk/jog tests validity is affected by
motivation, exercise, tolerance, distance accuracy
walk/jog tests ____ fit individuals
over-predict
run tests viable for
fit or conditioned individuals
run test validity affected by
test experience due to pace, client motivation, running economy, distance accuracy
bike tests relatively difficult to implement because
equipment and technical expertise are required
bike tests are viable for
multiple populations but a moderate level of fitness required
bike tests validity is high with
strict portal adherence
bike test revenant factor
leg strength
easy physiological guide for setting training intensities
HR
heart rate training zone
heart rate range relative to an individuals heart rate max that should be maintained during cardiovascular training to obtain targeted adaptations
the first step to obtaining HRTZ
estimate the clients maximal heart rate
max HR formula
220-age
obese individuals max HR formula
200-(.5 x age)
