Aerobic Fitness Flashcards
(40 cards)
What is CR fitness?
The ability to complete moderate-high intensity exercise using larger muscle groups for a prolonged period of time.
what is VO2max?
Functional ability of the CR system
or the rate of oxygen uptake during maximal exercise
Are power and capacity the same?
No. Power is time based and capacity is the total volume of work you can do.
What is the difference between VO2max and VO2peak?
VO2max plateaus and is maintained for several minutes
VO2peak has no plateau and is not maintained
-used more for describing the intensity of the task.
What kind of relationship is there between workload and VO2?
Linear
What is the relationship between body weight and VOmax?
they are inversely proportional for relative VO2max
T or F. Larger people will have a higher absolute VO2max
True
What age groups are at moderate risk if they have 2 or more risk factors identified on the PAR-Q?
Men >/= 45 and women >/= 55.
Who is classified as high risk during maximal and sub-maximal tests?
any individuals with one or more signs or symptoms of CV and pulmonary disease.
Name two direct measure tests.
Treadmill and ergometer
Name 5 indirect measurement tests.
mCaft, 20mSR, 1.5 mile run, Bruce treadmill test, Ebbeling treadmill test, Astrand cycle test,
YMCA cycle test.
What are the assumptions between HR, PO, and VO2 for indirect tests?
That they are direct and linear in relation between each other.
What are the assumptions for sub-maximal indirect predictions for VO2?
They assume that after the sub-max is reached that the VO2 or HR will continue along the same slope.
What are a few characteristics of a good maximal test?
- VO2 plateaus
- HR plateau
- RER> 1.14
- Venous lactate >8mmol/L
- RPE >17
- Volitional fatigue
What is a good way of increasing anaerobic threshold?
interval training
what are the ranges for O2 and CO2 percentages in the calibration gas?
15-17% O2
3-5% CO2
What does STPD stand for?
Standard Temperature (0 degrees celcius), Pressure (760 mmHg), Dry (No water vapour)
What does BTPS stand for?
Body Temperature (37 degrees), ambient Pressure, Saturated with water vapour
What does ATPS stand for?
Ambient temperature (~20 degrees), ambient pressure, Saturated
What are the Pros to Direct treadmill and cycle erg maximal tests?
Lots of comparative research Set protocol - known to be valid and reliable Motivation possible Automatic controls Other info possible (eg. RER)
What are the Cons to Direct treadmill and cycle erg maximal tests?
VO2max tends to be 10% lower for cycle compared to the treadmill for regular population
Intimidating for non-athletic pop.
Expensive
Time consuming
Assuming peak is max if no plateau is observed
Highly electronic
Assumes client is able to physiologically push to max
What is the population best suited for a direct treadmill and cycle erg max test?
Athletic populations for who the results are meaningful
Clinical because you have accurate results and it allows for other measures during a stress test
What are the pros to Cooper’s 1.5 mile run?
Research available for norms Good for diverse populations and large groups Can obtain a field max HR Inexpensive portable Faster turnover Competition provided by a large group Measures performance/ability to achieve high levels of effort
What are the cons to Cooper’s 1.5 mile run?
No universal surface Not as much extra information Learning curve to the pacing Self measure of HR Predictor Running is not safe for everyone
