Virtual Metabolic Cart Tutorial

The Simulator contains exercise data embedded within the program itself.

When you run the Simulator, this data is displayed at 2 second intervals -

effectively a fast forward function - that allows you to explore the various data

presentations.

Load and run the program click OK on the

opening dialog box, then OK on the

SIMULATION button. You will now be presented

with a Test Data dialog shown left.

Click OK. A prompt reminds you to select a VIEW. Click OK then select View

from the Menu Bar. Three basic views are available, but to begin with select

Table

. You are now presented with colour coded data parameter buttons. Click

on all the buttons.

Click the

TEST

Button to start the simulation. The selected data will scroll down

the screen.

The dialog box allows

you to enter personal

data, sampling

conditions and

comments.

You can select or

deselect a

parameter by

clicking its’ button

As the data scrolls

you can select or

deselect in real time.

Graphical View

Click View on the Menu bar, deselect Table and Select Graph. The first 6 param-

eters from the Table view will be shown in graphical representation. This is the

maximum allowed on a single graph,

however you can deselect and select

any other parameter

. The graph will appear off the right hand side of the dis-

play. The scroll bar at the bottom of the graph allows you to scroll the graph to

the left or right.

Select

View

then

Overview

. The graph is now contained totally within the

display.

The Values shown

colour coded above the

parameter buttons

show the last table

value.

Click

View

then

History

. The graph now shows a thin blue vertical History line.

Use the mouse to move the History line across the graph. Observe that as you

traverse the graph the colour coded values above the parameter buttons

change, and in fact reports the values at that particular time. You can deselect

and select any parameter using the parameter buttons.

For a better view of the values, Click

View

then

Data

. The height of the graph is

reduced, and large data boxes are displayed.

View Combinations

Any two of the three basic views - Table, Graph and Data - can be viewed in

combination.

All of these view combinations can be selected to display in

real time during exercise using the COVOX Metabolic Cart.

In this example all the

parameters have been

deselected apart from VE,

VeO (Oxygen equivalent),

Vec (Carbon Dioxide

equivalent) and Heartrate.

This view can be used for

estimating anaerobic

threshold. It is generally

accepted that this occurs at

the start of a continued

increase in

VeO, without a similar

increase in VeC. You might

also observe a sudden

increase in VE.

Exercise Prescription

Provided your data set includes heart rate, then you can generate a

Cardiovascular Exercise Prescription. This is a classic prescription based on

heart rate intensity and energy expenditure. It’s generally accepted that heart

rate intensity above 60% of aerobic capacity(VO

2

Max) will illicit an aerobic

training effect. Coupled with an energy expenditure of 300Kcals per training

session, improvement in basic fitness is practically guaranteed.

There may be times however when you would prefer to set up your own training

criteria. The prescription therefore allows you to set heart rate intensity

according to a percentage of VO

2

max, and energy expenditure. For elite

athletes, heart rate intensity of 90% VO

2

max might be at anaerobic threshold,

and energy expenditure of 1000 Kcals might well be within their capability. For

de-conditioned individuals or those in cardiac rehabilitation, a heart rate intensity

of 40-50% VO

2

max and 100 Kcals might be more appropriate. Whatever your

thoughts, the program allows

you

to decide. Once you have decided on energy

expenditure and heart rate intensity, the prescription calculates the exercise

duration.

Click

View

on the menu bar and select

Prescription.

The dialog box below

pops up and you can set up the training criteria. If the fitness assessment was

sub-maximal the max heart rate defaults to 220 - age. If you know the client’s

max heart rate, then enter it in the Predicted Max Heart Rate box.

The dialog box

allows you to input

Energy Expenditure,

Training Intensity

and known Max

Heart Rate

Next

Click OK

and the

prescription is generated

immediately. The prescription

also gives a fitness score

according to the Astrand

scale of cardiovascular

fitness. You can change the

prescription by closing it,

then

Click View

and select

Prescription

again.

Other features

The COVOX Metabolic Cart can be used as a stand alone gas analyser that

can be used to analyse the contents of a Douglas bag. Reboot the program,

Click

View

then

Analyser.

A port at the rear of the COVOX

Metabolic Cart can be connected to a

Douglas bag via tubing and the

contents analysed for Oxygen and

Carbon Dioxide concentration.

Click

View

then

Gas Meter.

The

COVOX Metabolic Cart can be

used as a stand alone gas meter.

This feature requires the use of a

bacterial and vapour filter, which is

available as an optional extra.
