Flashcards in Aerobic Testing Deck (21):
1

what is considered one of the most important determinants of health

aerobic fitness

2

aerobic fitness represents the ability to perform?

dynamic exercise involving large muscle groups at moderate to high intensity for prolonged periods

3

what is VO2 max
- what is it dependent on?

the maximal volume of 02 one can consume during exhaustive exercise
- transport of -2 via the cardiorespiratory system to the working muscles
- the ability of the muscle to utilize the O2 during exercise

4

V02 =

(HR x SV) x (a-VO2 diff)

5

measures the actual construct of interest

direct test (treadmill and ergometer)

6

measures a construct known to be related to the actual construct of interest

indirect test

7

during the bruce treadmill protocol you increase what when?

the speed: 1.7, 2.5, 3.4, 4.2, 5.0
and 2% grade every 3 min
- starting at 1.7 and 10%

8

when are you considered done during the bruce protocol treadmill test

- reach volitional fatigue
- HR plateaus (within 5bpm for 2 minutes)

9

equation for bruce treadmill for makes and females
(time in minutes)

males = 14.76 - 1.379 (time) + 0.451 (time ^2) - 0.012 (time ^3)
females = 4.38 (time) - 3.90

10

modified bruce treadmill protocol

speed: 1.7, 1.7, 1.7, 2.5, 3.4, 5.0
grade: 0, 5, 10, 12, 14, 16, 18
(5% at 3 and 6 min, 2% every 3 minutes after)

11

single stage models?
multistage models

-use one submax work load
- increase grade or intensity (typically 3 minutes)

12

mCAFT step test

- select starting stage based on age and gender -
- calculate 85% HR max in bpm and beat per 10 seconds
- complete 3 minutes stages until 85% HRmax reached

13

mCAFT equation

[17.2 + (1.29 x O2 cost) - (0.09 x wt in kg) - (0.18 x age)]

14

queens step test

step 16.25 " 22 steps/min for females and 24 for males
- 3 minutes duration
- HR at end (time = 3.05)
- VO2 max (maes) = 111.33 - (0.42 x HR)
- VO2 (females) = 65.81 - (0.1847 xHR)

15

YMCA submax cycle test

- calibrate
- start pedalling at 0.5 kp for 50 rpm
- check HR at end of each minute
- HR for last minutes of warm up determines subsequent workloads
- done when steady state reached or within 10 bpm of 85% HR max

16

astrand submaximal cycle test

- calibrate
- target HR 120/125-170 bpm at 50 rpm
- workload using resistance of 0.04 x BW (round to nearest 1 kp for men and 0.5 kp for women
- take HR at end of min 2
(adjust if not within 125 - 160)
- record HR , rpm and confirm workload at end of each minutes
0 determine avg HR at minute 5 and 6 unless adjustment made at min 2 then do min 7-8 or greater than 10 bpm different
- use the avg last 2 HR to calculate VO2 max

17

units for VO2 absolute and relative

absolute: L/min or ml/min
relative: ml/kg/min

18

Ebbeling Treadmill test

- calculate 50-70% HR max
- select warm up for 4 min that gives HR between this
- increase grade to 5% at end of 4 min
- measure HR at end of each minutes
- average HR for min 3 and 4 to determine final state HR (if within steady state)

19

4 submaximal fitness end criteria

1. target HR obtained
2. cannot maintain cadence of workload
3. client ask to stop
4. sign of physiological stress

20

what is the active recovery protocol for submaximal test

- low intensity aerobic cool down for 3 minutes, measuring HR at the end of each minute (can extend if not recovered)
- seat client and measure 1 and 3 minutes HR and BP

21

what is the active recovery protocol for maximal test

- low intensity aerobic cool down for 5 min measuring HR at end of each minutes
- participant must be supervised for 15 min after cool down
