Lecture 4 - Aerobic testing Flashcards
_______ fitness is considered one of the most important determinants of health.
aerobic
______ ____ = maximal volume of O2 one can consume during exhaustive exercise.
VO2 max
What 2 things is VO2 max dependent upon?
- Transport of oxygen via the cardiorespiratory system to the working muscles.
- The ability of the muscle to utilize the oxygen during exercise
A ______ test measures the actual construct of interest; an _____ test measures a construct known to be related to the actual construct of interest.
direct;indirect
In _______ models to estimate VO2 max, record HR at the end of each minute, and the client must achieve steady state HR (within __bpm over subsequent readings) over duration of test/stage.
submaximal; 5
In the Queens college step test, what is the rate of stepping for females? For males?
22 steps/min; 24 steps/min
In the YMCA submaximal cycle test you start peddling at ___kp for __ mins at ___rpm.
0.5; 3; 50
How do you estimate workload in the Astrand cycle test?
0.04 x BW (round to nearest 0.5kp for women and 1kp for men)
In the Astrand submaximal cycle test, determine average HR at minute 5 and 6 unless?
- Adjustment made at minute 2 (then take average HR from min 7 and 8)
- > 10bpm difference (then continue minute bu minute until SSHR is achieved within 10bpm)
To calculate VO2 max from the Astrand cycle test, used the average of the last two ____ and ____ to calculate VO2 max.
HRs; PO
_________ VO2 is directly related to body size; _______ VO2 max can compare CR fitness regardless of body size
absolute; relative
In the Ebbeling treadmill test, calculate ___%-___% HR max and select a warm up speed for 4 minutes that elicits a HR between those ranges (usually ___-___ mph)
50-70; 3.2-4
What are the 4 submaximal fitness end criteria ?
- Target HR/HR zone obtained
- Cannot maintain cadence or workload
- Client asks to stop
- Signs of physiological stress
What is the AR protocol for submax tests?
Low intensity aerobic cool down for 3 minutes, measuring HR at the end of each test (can extend by additional 1 - 2 minutes if not sufficiently recovered). Seat client and measure 1 and 3 minute HR and BP.
What is the AR protocol for a max test?
Low intensity aerobic cool down for at least 5 minutes, measuring HR at the end of each minute. Participant must be supervised for a minimum of 15 minutes upon completion of cool down.
There is a _______ relationship between VO2 and HR.
linear
What are 4 assumption of indirect tests?
- SSHR is obtained for each work rate
- The max HR for a given age is uniform
- A linear relationship exists between HR, VO2 and PO
- Mechanical efficiently is the same for everyone
What are the 2 big assumptions?
- The max HrR for a given age is uniform
2. Mechanical efficiently is the same for everyone
HR max can vary up to +/- ___ bpm from age predicted max.
20
A runner with poor running economy would exhibit _____ VO2/HR at any given running speed than an economical runner.
higher
Oxygen consumption increases _______ with workload.
linearly
VO2 can be measured directly through open circuit ______, or can be estimated by _____.
spirometry; workload
What speeds are the ACSM walking equation most accurate for?
1.9-3.7mph
The ASCM walking equation is most accurate for speeds over ___ mph, or as low as ___ mph if participant is running.
5;3
The flywheel on a cycle ergometer moves at ____/rev/
6m/rev
There are _____ kp x min/min per Watt.
6.12
In open-circuit spirometry, gas to be analyzed should be drawn directly from ____ _____.
mixing chamber
How long should a graded exercise test last?
8-12 minutes
What are peak criteria for a VO2 test?
At least 3 of:
- HR: fails to increase with increasing workload, OR is at or close to age-predicted max (+/- 20bpm)
- Blood lactate concatenation ? 8mmol/L
- RER over or equal to 1.15 or 1.1
- Volitional fatigue (RPE equal to or greater than 17 on Borge scale)
What is max criteria for a VO2 test?
- HR: fails to increase with increasing workload, OR is at or close to age-predicted max (+/- 20bpm)
- Blood lactate concatenation ? 8mmol/L
- RER over or equal to 1.15 or 1.1
- Volitional fatigue (RPE equal to or greater than 17 on Borge scale)
- A plateau (<2mL/kgxmin change with increasing workload)
The overall risk of exercise testing (maximal) in a mixed object population is approximately ___ events in _______ tests.
6/10,000
Vigorous exercise increases the risk of sudden cardia death only in individuals with ________ ______ _______ whether diagnosed or not.
pre-existing heart disease
The _____ _____ is the level of oxygen consumption at which there is a rapid and systematic increase in blood lactate concentration or a non-linear increase in ventilated.
anaerobic threshold
You can predict the AT with _____ or ______ _____ concentration.
ventilation; blood lactate
