1
Q

cardiorespiratory fitness (CRF)

A

the ability of the circulatory + respiratory systems to supply oxygen to skeletal muscles during sustained physical activity

-reflects the functional capacities of the heart, blood vessels, lungs, + skeletal muscles to perform wok

Q

running/walking lab tests

A

-Bruce
-Balke
-Astrand

20
Q

running/walking field tests

A

-12 min
-Pacer
-1.5 mile
-Rockport mile

21
Q

step tests may be too intense for…

A

sedentary/DECONDITIONED people
-also requires a lot of balance

22
Q

step tests

A

-McArdle step test
-YMCA step test
-Harvard step test
-Queens College step test

23
Q

cycle test are preferred for who

A

for some disabilities that could be made worse by weight-bearing activities

24
Q

cycle tests

A

-YMCA cycle test
-Astrand
-Rhyming cycle test

25
arm ergometry is beneficial for who
clients with lower body disabilities
26
describe how arm ergometry differs from other modalities
HR + BP tend to be higher at submaximal loads for arm ergometry relative to lower body modalities
27
the most accurate protocols will be ____
graded -changing intensity
28
RER = 0.7
100% fat
29
RER = 1
100% carbs
30
RER > 1
producing more CO2 than consuming -comes from buffering hydrogen ions
31
once RER is above 1...
we know they are getting closer to VO2 max
32
appropriate room temperature for VO2 max testing
68-72 F
33
appropriate humidity for VO2 max testing
< 60%
34
field test
outside laboratory
35
benefit of field test
multiple people can be measured at once
36
laboratory test
within lab -more accurate
37
closed-circuit spirometry
the air that the organism is taking in comes from a sealed container where the precise amounts of elements are known -when the organism exhales the air is collected in a different sealed container and compared to air in the original sealed container
38
open-circuit spirometry
the air that the organism is taken in from the surrounding/environmental air -when the organism exhales the air is collected and compared to the assumed composition of the air they inhaled
39
environmental air makeup
-78% nitrogen -21% oxygen -0.03% carbon dioxide -1% other gases
40
calorimetry
the measurement of the amount of heat involved in a chemical reaction or other process -we use this to estimate energy balance + energy expenditure
41
direct calorimetry
almost never seen in human fitness measurements -only in extreme lab research methods
42
indirect calorimetry
used much more often; estimation of calories from oxygen consumption -in all tests studied in class, indirect calorimetry is used
43
longest the YMCA test will last
12 min
44
shortest the YMCA test will last
6 min
