33
VE/VCO2 at rest and changes during incremental exercise:
- at rest: in the 30s | - changes: initial decrease, remains relatively constant throughout submax, followed by a steady increase beyond AT
34
Variability in VO2 max testing: Katch et al. (1982):
- tested 5 subjects between 8 and 21 times - found that VO2 max varied +/- 5.6% (1 SD) and +/- 11.2% (2 SD) - roughly 3-5 ml/kg/min for a 50 ml/kg.min individual
35
Variability in VO2 max testing: Thoden (1992):
approximately +/- 3 ml/kg/min for athletes
36
Bell (1989) reliability for VO2 max testing:
test retest r = 0.96 for rowing VO2 max
37
What if you don't have a metabolic cart?
- a variety of protocols and formulas exist to predict VO2 max - can be either maximal or submaximal - regardless, they use some sort of physiological performance indicator in a formula to provide a predicted VO2max or VO2peak
38
Indirect submaximal VO2 max tests:
- mCAFT - YMCA - Astrand - PWC - ACSM - Ebelling - Rockport
39
Indirect maximal VO2 max tests:
- Leger - Bruce - Mod. Bruce - Balke - Cooper
40
What do you need for indirect calculation of VO2?

41
Other maximal indirect tests:
- multi-staged - treadmill preferred (5-11% higher than bike) - good estimation of true VO2 max - protocol can be adapted for many populations
42

exhaustion
46

47
The Naughton treadmill test is a ______, _____ exercise test to _____.
- continuous - progressive - fatigue (volitional exhaustion)
48
The Naughton treadmill test is specific to what type of individuals?
higher risk individuals
49
The Naughton treadmill tests starts at....
- 0% grade and 1.0 mph | - increased speed at 2 min (2 mph), and grade (+3.5%) every 2 min.
50
Naughton: time to ______ is recorded.
exhaustion
51
Cycle ergometry maximal prediction mode:
- can be discontinuous or continuous | - max power output (W) attained is used to estimate VO2
52
Limitations of cycle ergometry:
?
53
Leger:
- maximal - 20m shuttle run test - need MAS (max aerobic running speed in km/hr)
54
Coopers:
- maximal - 12 minute run test - need distance (m)
55
Why use predictive submaximal VO2 max tests?
- safe, avoids max cardiovascular stress - relatively inexpensive - less sophisticated equipment required - less expertise required - more conducive to "mass" testing - some test protocol durations are shorter than maximal protocols
56
Submaximal tests for predicting VO2 max is based on:
- positive linear relationship between power output, VO2 and HR - assumption that max HR can be predicted similar in all individuals - assumption that variability in HR (day to day) is minimal - assumption that efficiency of exercise is similar between individuals at max
57
Best predictive power using HR occurs between HR's of....
- 120-170 bpm | - prediction may be less accurate above and below these HR's (10-20%)
58
Predicting VO2 max using a multi-stage equation: cycling ergometer test needs:
- weight - HR - age
59
Steps for predicting VO2 max using a multi-stage equation:
1. determine power output for each stage (ACSM metabolic equation for cycle ergometry) 2. determine slope of the line of best fit (use first submaximal workload and final exercise stage) 3. determine VO2 max
60
How to predict VO2 max by graphing:
- use metabolic equations to calculate VO2 for each stage | - plot HR (end stage, 3rd min only) vs calculated VO2 and extrapolate to age predicted HR max
61

69
General protocol for warm up and cool down:
- warm up: 5 min at low intensity at 20-30% HRR or 35-45% HR max - warm up: similar movements as activity - monitor HR, BP, RPE, symptoms prior to, during and after exercise (1, 3 and 5 min) - cool down: active recovery for 5-10 minutes
70
Critical competency is the ability to measure:
- resting and post-exercise BP | - resting, steady state exercise, and post exercise HR via palpation
