Section 1: Introduction
%
Things to consider before beginning an exercise program
Consult a physician
Anyone considering an exercise program or an increase in activity should consult a
physician. If you have cardiovascular disease or there is a history of such disease in
your family, are overweight or are not currently involved in an exercise program, it is
highly recommended that you follow the guidance of your physician before and during
an exercise program or any other increase in physical activity.
Consult a Professional Fitness Trainer
In addition to following the recommendations of a physician it is advisable to consult a
professional fitness instructor or personal trainer to develop an overall fitness
evaluation/wellness program that is tailored to your particular needs.
Understanding the Importance of Warming Up and Cooling Down
It is important to gradually “warm up” and “cool down” prior to and at the end of each
work out, respectively. Always try to incorporate a series of basic stretches before and
after each workout. Stretching encourages the necessary flexibility to help prevent sore
muscles and injury during daily activities. Do not abruptly end your exercise session on
the AlterG Treadmill. Always restore your full body weight slowly and include a few
minutes of walking at full body weight and low intensity before stopping your exercise
session.
How Often and for How Long Should You Exercise?
The American College of Sports Medicine recommends a frequency of 3 to 5 days per
week for duration of 20 to 60 minutes, dependent on the intensity of the exercise
session.1The United States Department of Agriculture suggests that physical activity
should be moderate or vigorous and add up to at least 30 minutes a day. The USDA
defines moderate as walking briskly at about 3.5 miles per hour while vigorous activity is
running or jogging at 5 miles per hour.2These are general guidelines; you should
determine what is appropriate for you with the help of your physician.

Ground Requirements
The AlterG Treadmill must be grounded electrically. If there is an electrical malfunction,
grounding provides a path of least resistance for electric current to reduce the risk of
electric shock. The AlterG Treadmill is equipped with a power cord with a grounded
plug (domestic systems). This plug must be plugged into an appropriate receptacle
(NEMA 6-20R) that is properly installed and grounded in accordance with the current
National Electrical Code as well as all local codes and ordinances. If you are at all
unsure of these requirements, contact AlterG for clarification.
Danger
Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or serviceman if you are in doubt as to
whether the product is properly grounded. Do not modify the plug provided with the
product – if it will not fit the outlet; have a proper outlet installed by qualified electrician.
Location Requirements
The AlterG Treadmill is 38 inches wide and 84 inches long. It weighs approximately
750 pounds. It needs to be placed on a structurally sound surface. If it is used above
ground level it is advisable to place it near the corner of the room or where the floor will
be strongest to ensure maximum support during high-speed, high-impact use. The
surface should be level to ensure minimal flexing of the AlterG Treadmill frame. It is
recommended that the AlterG Treadmill be placed on a rubber mat or padded
indoor/outdoor style carpet. The front of the AlterG Treadmill needs to be within 10 feet
(3.05 meters) of the proper electrical outlet. Check with a qualified electrician or AlterG
if you plan on extending the cord in any way. Make sure you leave at least 24 inches on
either side of the AlterG Treadmill to allow the bag to expand during inflation. Allow 40
inches behind the AlterG Treadmill to accommodate a user getting in and out of the
AlterG Treadmill system safely.
We recommend an area at least 12 feet (3.66 meters) long by 8 feet (2.44 meters) wide
to provide adequate space for operation and user access. Also check ceiling height to
ensure users won’t hit their heads. The treadmill surface is approximately 8” (20 cm) off
the floor when level and can be higher when the subject is running on a grade. An 8-
foot (2.44 meter) ceiling may be too low for taller users.
Transporting your Treadmill
Contact AlterG if you plan on moving your treadmill. Damage sustained by improperly
moving the AlterG Treadmill will not be covered by your warranty.

Section 3: Principle of Operations
AlterG’s technology was originally conceived as part of an effort to help NASA’s
astronauts maintain fitness during prolonged space flight. AlterG pioneered the concept
of combining this technology with an advanced pressure regulation system and treadmill
into a machine that provides the most effective and comfortable body weight support
system available today.
Physics & Technology Behind the AlterG Treadmill
Differential Air-Pressure Technology
The physical lifting force generated by the AlterG Treadmill comes from a difference in
air pressure around the user’s upper and lower body. The AlterG Treadmill uses this
methodology, known as Differential Air Pressure (DAP) technology to unweight the
user.
An inflatable fabric enclosure covers the treadmill. In the middle of the enclosure is a
hole through which the user steps onto the surface of the treadmill. The user wears a
special pair of shorts, and these shorts are zipped into the hole in the enclosure. A
blower is used to inflate the enclosure. The pressure generated in the inflated
enclosure provides a lifting force against the body. Because the pressure is only slightly
above atmospheric and evenly distributed, the force on the lower body is almost
imperceptible. The AlterG Treadmill provides a level of comfort while exercising
unmatched by other unweighting systems.
Figure'1.'Diagrammatic'Representation'of'Lifting'Force'

D-000348'Rev.'A'
16'
Pressure Regulation System
AlterG has developed an advanced and very sophisticated pressure regulation system
that ensures the AlterG Treadmill has extremely accurate weight control with good
reproducibility between sessions. When you run in the AlterG Treadmill, the natural
bouncing motion of your body changes the shape and volume of the bag. This effect
would change the interior pressure of the bag and your effective exercise weight if it
were not for the pressure regulation system in the AlterG Treadmill that monitors and
reacts to these changes. This technology makes rapid adjustments to the bag
pressure, maintaining the pressure in the bag and your exercise body weight at near
constant levels.
Air Seal Shorts
In order to seal users into the AlterG Treadmill in a comfortable and convenient manner,
AlterG has designed a special pair of shorts. These create an airtight environment
around the lower body, and the zipper provides a mechanism to quickly attach and
detach from the enclosure. The shorts are easy to take on and off and sealing with the
machine is as simple as zipping up a jacket. The shorts are similar to those worn by
many professional athletes for compression and support during training activities.
Shorts are manufactured using the following materials: 90% Neoprene, 10% Urethane
coated Nylon.
Figure 2. AlterG Compression Shorts

D-000348'Rev.'A'

Section 4: Operating the AlterG Treadmill
'
POWERING UP
The AlterG Treadmill is turned on by
operating the switch located on the front
cover of the system.
Before you turn on the AlterG
Treadmill you must do two things:
1. Make sure there is no one
standing on the treadmill when
you power up the system.
2. Make sure the cockpit is locked
in its topmost position so the
inflatable enclosure is not sitting
on the treadmill surface.
The computer that controls the AlterG Treadmill weighs the treadmill when the system is
first turned on. The computer will receive an erroneous reading if either the fabric
enclosure or an individual is on the surface of the
treadmill. The proper location of the cockpit on
power-up is shown in Figure 4.
Note: Once the power switch is turned on,
wait 30 seconds before the subject attempts
to enter the treadmill. The system requires 30
seconds to run a series of diagnostic tests.

Figure 4 Proper Location of Cockpit on
Power-up

D-000348'Rev.'A'

Putting on the Shorts
Your AlterG Treadmill comes with dedicated shorts that ensure an airtight seal in the
fabric enclosure. Slip the shorts on in the same manner as a conventional pair. The life
of the shorts will be extended and they will be easier to get on if you first remove your
shoes.
Note: End of Life Product Disposal: AlterG products contain no waste or residual
materials. The products have significant recoverable and recyclable elements. Consult
your distributor for the safe and appropriate disposal of product no longer in service.
Select a short size that is snug but not uncomfortable, and make certain the tag is at
your back and on the inside of the shorts. The long tail of the zipper should be in front.
It is advisable that you wear a pair of running shorts or tights under the AlterG shorts.
Stepping into Out of the Treadmill
Lower the cockpit so it compresses the bag against the treadmill surface (Figure 5).
Push it all the way down for ease of entry. Enter from the back and step into the
opening in the fabric enclosure. It is fine to step on the fabric as you enter, but make
sure that you have no rocks or sharp objects embedded in the soles of your shoes that
could mar or damage the bag.

Adjusting the Height of the Cockpit
The cockpit slides up and down on a bearing system and is counter-weighted to make it
easy to lift.
CAUTION: Before lifting the cockpit, ensure that the cockpit
lock is in the open position, all the way to the left side of its
travel. If it is not fully unlocked, it may engage in the lowest
position as you lift. See Figure 6.
Stand centered in the hole in the fabric enclosure facing forward with both feet on the
treadmill belt. Lower yourself by bending at the knees and grasp the cockpit on either
side. With a straight back and good lifting technique, lift the cockpit to the appropriate
height and engage the lock by pulling the lock lever to the right. Do not force the lever.
You may have to “jiggle” the cockpit up and down slightly to get the lock pins to engage.
When fully enaged, the lock lever will be positioned all the way to the right in the slot.
See Figure 7.
