Q

Are power and capacity the same?

A

No. Power is time based and capacity is the total volume of work you can do.

Q

What is the difference between VO2max and VO2peak?

A

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.

Q

What are the assumptions for sub-maximal indirect predictions for VO2?

Q

What does STPD stand for?

A

Standard Temperature (0 degrees celcius), Pressure (760 mmHg), Dry (No water vapour)

18
Q

What does BTPS stand for?

A

Body Temperature (37 degrees), ambient Pressure, Saturated with water vapour

19
Q

What does ATPS stand for?

A

Ambient temperature (~20 degrees), ambient pressure, Saturated

20
Q

What are the Pros to Direct treadmill and cycle erg maximal tests?

A 
Lots of comparative research
Set protocol - known to be valid and reliable
Motivation possible
Automatic controls
Other info possible (eg. RER)
21
Q

What are the Cons to Direct treadmill and cycle erg maximal tests?

A

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

22
Q

What is the population best suited for a direct treadmill and cycle erg max test?

A

Athletic populations for who the results are meaningful

Clinical because you have accurate results and it allows for other measures during a stress test

23
Q

What are the pros to Cooper’s 1.5 mile run?

A 
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
24
Q

What are the cons to Cooper’s 1.5 mile run?

A 
No universal surface
Not as much extra information
Learning curve to the pacing
Self measure of HR
Predictor
Running is not safe for everyone
25
Q

What are the assumptions made in Cooper’s 1.5 mile run?

A

Clients are going to volitional fatigue
The person with the higher VO2 will be the fastest in performance
Efficiency of anthropometrics are equal
Efficiency biomechanics are equal

26
Q

What is the best suited population for Cooper’s test?

A

Athletic/active, large pop. such as teams, educational settings, occupational settings

27
Q

Pros for the mCaft.

A

Inexpensive
Portable
Submaximal - accessible for many fitness levels
Easy to administer
More of an everyday functional movement than running/cycling

28
Q

Cons for the mCaft

A

The music - HAHAHA
Not suitable for low flexibility, balance
Clients with no rhythm
Submaximal prediction
Not as easy for the client to understand connection to fitness

29
Q

Assumptions with mCaft

A

Assuming a linear relationship between HR and VO2 at every intensity level
Assuming we know work rates
HR reflects the workload
Norm values are representative
Calves do not fatigue before energy system

30
Q

Population best suite for mCaft

A

Occupational and educational setting
Not great for elderly or very athletic people
good alternative to running or cycling

31
Q

Pros for 20mSR

A 
large groups can be tested at once
relates well to lots of sports
inexpensive and portable
norms available
competitive
easy protocol
can measure max HR
32
Q

Cons for 20mSR

A

Timing and pacing can be difficult for some
Need a large space
motivation plays a role
Learning curve
requires referees for the lines
underpredicts for high VO2, overpredicts for low VO2
Reputation

33
Q

Assumptions with 20mSR

A

VO2 and work rate have a linear relationship
True VO2 is reached
Good performance is due to high VO2 and not another factor

34
Q

Population best suited for the 20mSR

A

Athletic population, large groups (teams), not suitable for injuries (knee and ankle)

35
Q

Pros for Ebbeling Treadmill test

A

Low risk
only 8 minutes
Walking

36
Q

Cons for Ebbeling treadmill test

A

predictive based on assumptions
Expensive
No rhythm required
Equations based on categories that are undefined
Requires a trained professional administer

37
Q

Assumptions with the Ebbeling test

A

Age-predicted HRmax
Walking speed based on gender, age and fitness level
Relationship between HR and VO2 is linear
“ “ HR and work rate is linear
Steady state is achieved before measuring HR
Differences in HR is due to fitness not efficiency of movement

38
Q

Population best suited for Ebbeling test

A 
clinical
occupational
educational
good for non-athletes, non-active pop.
Injured
Elderly
39
Q

What are 4 assumptions made for submaximal tests?

A
  1. Steady state HR is achieved and is consistent for each exercise work rate.
  2. Linear relationship of HR and VO2
  3. Mechanical efficiency is constant among individuals
  4. HRmax for clients of a given age is similar
40
Q

What is the actual relationship of HR and VO2

A

It is linear for low to moderate exercise and becomes curvilinear at high work rates.
