CORRECT ANSWERS
Perceived Exertion - CORRECT ANSWERS The subjective detection and interpretation of
the intensity of effort during exercise
Psychobiological Gestalt on perception of effort is linked to what 4 factors? - CORRECT
ANSWERS 1. physiological factors
2. psychological factors
3. Milieu (environment)
4. exercise stimulus
what are the 4 scale types that are used for perceived exertion? - CORRECT
ANSWERS nominal, ordinal, interval, ratio
what can nominal scale types be used for? - CORRECT ANSWERS classification
what can ordinal scale types be used for? - CORRECT ANSWERS rank order
why is ordinal scale not a useful scale for exercise? - CORRECT ANSWERS it doesn't show
the borg scale difference
what can interval scale types be used for? example? - CORRECT ANSWERS distances;
doesn't have a true zero;Fahrenheit
what are ratio scale types used for? example? - CORRECT ANSWERS ratios; has a true zero
and can go to infinity; kelvin
,what is the advantage of using a ratio scale? - CORRECT ANSWERS yields the most
accurate description of the relationship between stimuli and perceptions
what are 3 types of ratio scales? - CORRECT ANSWERS 1. cross-modality matching
2. magnitude estimation
3. magnitude production
Steven's Power Law says what about magnitude of perception? - CORRECT ANSWERS as
power output increases linearly, the perception of how intense the exercise stimulus feels grows
exponentially
what is a disadvantage of a ratio scales? - CORRECT ANSWERS inter-individual
comparisons are not possible
person who developed several valid methods for assessing perceived exertion - CORRECT
ANSWERS Gunnar borg
most common, ordinal perceived exertion scale that is used for most applications - CORRECT
ANSWERS Borg's 6-20 scale
perceived exertion scale that is used for research to study non-linear exercise responses; is
ordinal with ratio-like responses - CORRECT ANSWERS Borg's 0-10 scale
what was the 6-20 scale was designed to be related to _______ - CORRECT
ANSWERS Heart rate
3 limitations of the 6-20 scale - CORRECT ANSWERS 1. ceiling effect
, 2. assumes all maxes are perceived the same (range principle)
3. not a ratio scale- gives linear, not curvilinear
Borg's range principle says what - CORRECT ANSWERS the perceptual range is set equal
for 2 people of different absolute abilities; that both people feel the same perceptual response
at the same max
what are the instructions for the Borg scale? - CORRECT ANSWERS 1. define perceived
exertion
2. explain differentiated ratings
a. overall
b. local
c. central
3. No right or wrong answer
4. anchor the perceptual range
a. present stimuli
b. by definition (as soon as above nothing 6.5 and max is 20 house is burning with children
inside)
exercise stimuli that are significantly correlated with RPE - CORRECT ANSWERS force,
power output, treadmill speed, weight lifted
physiological responses that are significantly correlated with RPE - CORRECT
ANSWERS Heart rate, oxygen uptake, lactate
the correlation between RPE and lactate in a cycle/treadmill test is: - CORRECT
ANSWERS r=.83
