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
