EXAM1- CV Assessments EXTRA

Question 1

cardiorespiratory fitness (CRF)

Answer 1

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

Question 2

reasons for measuring CRF

Answer 2

-identifying physiological strengths + weaknesses
-ranking people for selection purposes
-predicting future performances
-evaluating the effectiveness of a training program or trial
-tracking performance over time
-assigning or manipulating training dosage

Question 3

in measuring CRF…

Answer 3

both resting + exercising assessments should be done

Question 4

1 MET =

Answer 4

3.5 mL/kg/min

Question 5

average resting VO2

Answer 5

3.5 mL/kg/min
-aka 1 MET

Question 6

for every liter of oxygen, we burn ____ calories

Answer 6

5 calories

Question 7

gross VO2

Answer 7

caloric cost of rest + exercise

Question 8

net VO2

Answer 8

caloric cost of exercise alone

Question 9

females/males generally have a lower VO2

Answer 9

females
-due to lower lean body mass + menstrual cycle

Question 10

how do we quantify RPE

Answer 10

Borg scale

Question 11

Borg scale

Answer 11

6-20
-based on HR of a 20 year old

Question 12

HR range of Borg scale

Answer 12

60-200 bpm

Question 13

using Borg scale, how do we calculate HR

Answer 13

RPE x 10 should be roughly equal to HR +/- 10 bpm

Question 14

modified Borg

Answer 14

for older individuals
-1-10
-used for when medications or age skew Borg scale results

Question 15

OMNI scale

Answer 15

same idea as Borg but catered to an individual mode + has a visual component
-beneficial for kids + older individuals

Question 25

arm ergometry is beneficial for who

Answer 25

clients with lower body disabilities

Question 26

describe how arm ergometry differs from other modalities

Answer 26

HR + BP tend to be higher at submaximal loads for arm ergometry relative to lower body modalities

Question 27

the most accurate protocols will be ____

Answer 27

graded
-changing intensity

Question 28

RER = 0.7

Answer 28

100% fat

Question 29

RER = 1

Answer 29

100% carbs

Question 30

RER > 1

Answer 30

producing more CO2 than consuming
-comes from buffering hydrogen ions

Question 31

once RER is above 1…

Answer 31

we know they are getting closer to VO2 max

Question 32

appropriate room temperature for VO2 max testing

Answer 32

68-72 F

Question 33

appropriate humidity for VO2 max testing

Answer 33

< 60%

Question 34

field test

Answer 34

outside laboratory

Question 35

benefit of field test

Answer 35

multiple people can be measured at once

Question 36

laboratory test

Answer 36

within lab
-more accurate

Question 37

closed-circuit spirometry

Answer 37

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

Question 38

open-circuit spirometry

Answer 38

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

Question 39

environmental air makeup

Answer 39

-78% nitrogen
-21% oxygen
-0.03% carbon dioxide
-1% other gases

Question 40

calorimetry

Answer 40

the measurement of the amount of heat involved in a chemical reaction or other process
-we use this to estimate energy balance + energy expenditure

Question 41

direct calorimetry

Answer 41

almost never seen in human fitness measurements
-only in extreme lab research methods

Question 42

indirect calorimetry

Answer 42

used much more often; estimation of calories from oxygen consumption
-in all tests studied in class, indirect calorimetry is used
