Treadmill

 

Controller

 

allows

 

for

 

the

 

scheduled

 

control

 

of

 

one

 

or

 

more

 

lanes

 

of

 

a

 

metabolic

 

treadmill

 

during

 

an

 

Oxymax

 

experiment.

  

Oxymax

 

can

 

be

 

used

 

to

 

set

 

customized

 

speed

 

schedules

 

for

 

treadmills

 

while

 

simultaneously

 

collecting

 

metabolic

 

data.

Experiment

 

Setup

 

A

 

custom

 

treadmill

 

schedule

 

consists

 

of

 

three

 

parts:

 

the

 

warm

up

 

period,

 

the

 

schedule

 

itself

 

and

 

the

 

cool

down

 

period.

  

When

 

Oxymax

 

initializes

 

the

 

specified

 

hardware

 

upon

 

startup,

 

it

 

sets

 

the

 

treadmill

 

speed

 

to

 

the

 

last

 

used

 

“warm

up”

 

speed

 

which

 

will

 

be

 

maintained

 

until

 

the

 

start

 

of

 

the

 

experiment

 

schedule.

 

Note:

 

Please

 

note

 

that

 

in

 

order

 

for

 

Oxymax

 

to

 

adjust

 

the

 

treadmill

 

belt

 

speed

 

the

 

Treadmill

 

Controller

 

must

 

be

 

set

 

into

 

either

 

the

 

“Run”

 

or

 

“Accel”

 

position

 

on

 

the

 

front

 

panel.

  

Switching

 

the

 

Treadmill

 

Controller

 

to

 

“Stop”

 

at

 

any

 

point

 

immediately

 

stops

 

the

 

Treadmill.

  

After

 

the

 

software

 

has

 

assumed

 

control

 

of

 

the

 

unit

 

the

 

Treadmill

 

Controller’s

 

controls

 

for

 

speed

 

and

 

electric

 

stimulus

 

will

 

be

 

disabled

 

until

 

the

 

controller

 

is

 

“Reset”

 

with

 

the

 

button

 

in

 

the

 

lower

left

 

corner

 

of

 

the

 

front

 

panel.

applied.
