Description of the Ariel Exercise System
The revolutionary Ariel Computerized Exercise System
(ACES) heralds a new era
in physical conditioning, executive fitness, sports training, rehabilitation and
research. The Personal computer approach to the practice of resistive exercise
is a quantum change in both thinking and application. The computer puts
resistive exercises into a broad new realm of possibilities for applications in
health care, human service, athletics, fitness, training and education.
This new generation of exercise equipment uses a state of the art computer to
monitor and produce instant feedback on the individuals' performance. With this
unique feature, ACES achieves the most efficient and productive
exercise and training program in the world today.
ACES combines a unique set of objectives which will be quite beneficial to
you and your organization. Naturally we have the objective to help you to
achieve maximum health and fitness in the shortest possible time, but we go one
step further. For the first time, you can now use high technology to manage and
control your exercise system.
Ariel Dynamics Inc. is a company founded by field experts in the areas of
fitness, exercise and rehabilitation. Our team of designers and programmers have
been involved in 5 existing successful companies, written over 200 scientific
papers, designed over 100 successful products, and worked with leading
corporations and agencies such as IBM, NASA, Wilson Sporting Goods, US Olympic
Committee and many more. This experience is evident in our hardware and
software. The features you will treasure are the most advanced in the fields of
rehabilitation, training and physical fitness.
In all the previous descriptions of exercise equipment, the user has had to
determine the amount of resistance and the number of repetitions desired. The
reason the user made these choices was, of course, that the exercise equipment
itself was inherently incapable of any intellectual participation. However, with
the advent of computers, it became possible to design exercise equipment with
artificial intelligence enabling the CES to select the best exercise method
based on the individual user.
ACES possesses several unique advances over other resistive exercise
mechanisms. The most significant of these advances is the introduction of a
stored program computer which monitors and selects the amount of force,
velocity, acceleration, work, power and fatigue assignment. These selections are
made based on continuous simultaneous measurements from the human performance.
The computer and its associated collection of unique programs allows the
feedback controlled resistance to vary not only with the measured parameters of
force velocity and displacement, but additionally, to modify that feedback loop
while the exercise is in progress. This modification can, therefore, reflect
changes in the pattern of exercise over time. The unique program selection can
effect such changes in order to achieve a sequential or patterned progression of
resistance for the optimum training effect. The advantage of this capability
over previous systems is that the user can select the overall pattern of
exercise and the system assumes responsibility for choosing the precise force
level, speed of movement, and temporal sequence to achieve that pattern. Hence,
this is the first 5th generation computer system where, in addition to assigning
a constant program, the computer has the intellectual capabilities to adjust and
modify its assignment to achieve excellence.
The revolutionary ACES can be used to measure and record joint and
associated muscle capabilities; diagnose and rehabilitate muscle and joint
injuries with out risk of re-injury; evaluate the results of prescribed
treatment; assist in the prevention of injury by indicating the effects of
certain physical stress; provide conditioning, reconditioning, and strength

mode, causes the desired performance goal to be highlighted on the exercise
display. The user then tries to attain that goal or target value with his or
her performance bar graphs.
- Allows for comparison of one limb to another, one user to another, or any
type of consecutive performance comparison.
The ACES series is the most advanced physical fitness and rehabilitation
system on the market. After years of research and development by the Coto
Research Center of Coto de Caza, California, a leading independent laboratory in
the fields of biomechanics and sports medicine, ACES strides past the
standard method of exercising and propels fitness training into a new dimension.
Computerized Biomechanical Analysis Inc. of Amherst, Mass. integrates the world
of computers to incredibly efficient exercise stations to guarantee the
individual the most effective and exciting method of exercising the 20th century
has to offer.
ACES employs a sturdy digital hydraulic resistor pack instead of
weights, springs or manually-adjusted hydraulic or pneumatics resistance to
insure safety, quietness and efficiency. By using color graphics monitors and
printers to illustrate the individuals' exercise performance, one can follow a
predetermined exercise program or create a physical profile relating to each
individuals' strengths, weaknesses, speed and endurance.
What ACES measures
The accurate measurement of human performance is important in evaluating
movement. Accurate and calibrated equipment is essential for the clinician in
his analysis of the movement.
The essential of movement analysis includes the following parameters:
- Position: The location of the limb segment in space.
- Range of Motion, Velocity, and Acceleration: These values
are dependent upon accurate position information. Range of motion is total
position change; velocity is the rate of that change; acceleration is the
rate of velocity change. These are computed values based upon the position
- Force: An external influence of pulling or pushing action
which causes movement to occur. An exercise system must be dynamically
calibrated to provide meaningful information in pounds, kilograms or newtons.
A known force must be applied to the system and its effect upon the
measuring device tabulated. Once a broad range of loads has been applied on
the system and measured dynamically, a force calibration value is achieved.
This calibrated information is stored in the computer memory to allow
calculation of the subject kinetics.
- Weight: Gravity exerts a force upon all objects which
results in that object having weight. Because gravity acts exclusively
downward, biological motions on systems must consider gravitation. Gravity
will act against a vertically upward motion and will aid a vertically
downward motion. 'Me computerized exercise system must account for the
gravitational effect. Only a computerized system with a closed loop system
can be calibrated for gravitational effect.
- Torque: A force which causes rotation. Mechanically,
torque is the product of the amount of applied force times the perpendicular
distance of that force from the axis about which the object will rotate.
Torque then is a function of both force and distance variables. The
calculation of accurate torque must rely on the computer capability of the
Position, acceleration and force must be considered in the measurement of
The common denominator to any movement is that movement is composed of the
following parameters: position, range of motion, speed of movement (velocity),
acceleration (change in velocity), force, torque, work, power and fatigue. ACES can control these parameters in different modes.
Some of the modes

ACES is designed to provide accommodating exercise resistance proportional to
the force applied by the exercising user. However, ACES further enhances the
unique effectiveness and utility of accommodating resistance by providing:

COMPUTERIZED DATABASE SYSTEM
ACES allows a sophisticated data system to utilize commercial
software packages such as Lotus 1-2-3 or dBase-H to manage a total clinical
ACES stores all the data on a diskette and this data can be fed into a
total database measurement. You may also record the directory of patients. 'Me
injury records saves you time by leading you efficiently through a series of
standard data entries - patient name, age, sex, height, weight, etc. You simply
type in a brief response, and the computer does the rest of the busy work. You
can record the following information:
|Activity during which injury occurred
|Type of injury
|Location of injury
|Severity of injury
|New or recurrent injury
|Requirement for a physician
|Duration of treatment
Each category is broken down into responses meaningful to the athletic trainer,
physician or coach. You may also add entries tailored to your own practice; no
time-consuming copying of information; no eligible handwritten entries; no need
for costly clerical help.
With the database system you can generate printed reports in minutes, saving
literally days of valuable times. Simply tell the computer which record
categories to scan and the program automatically generates a frequency count
with row and column totals.
The most exciting ability is to combine the data management with the data stored
from the subject performance. This allows you to report any specific data for
range of movement, force curve, velocity curve, torque curve or statistical
information. These data can be compared to standards for efficient evaluation of
the person training on the exercise system.
The unique feature that sets ACES apart from all the other exercise
systems is the Ariel interface between equipment and a state-of-the-art
computer. This high technology advances the activity of exercise past the
drudgery of lifting weights, weight stacks and simple hydraulic pneumatic valves
and places it in an exciting, colorful and informative world of resistive
The programming of ACES contains an extensive amount of possibilities
for the person who strives for the fastest and the most efficient way to build
up strength, endurance, power and general physical fitness. The CES is also
invaluable for the physical rehabilitation specialist, the sports trainer and
the researcher, since its computer graphics and printouts contain information
that no other sophisticated rehabilitation equipment can possibly approach.
Some of the screens that appear on the Ariel monitor are:
|Exercise Selection - lists several User or Pre- defamed exercises to

comparison between limbs.
PROGRAMMABLE ACCOMMODATING RESISTANCE
ACES provides an accommodating resistance, that is, the exercise
resistance is directly proportional to the intensity of effort applied by the
exercising user. This feature is uniquely advantageous in rehabilitation and
training, as the exercise resistance automatically accommodates; to varying
strength levels throughout the range of motion of the exercise, from repetition
to repetition throughout the duration of the exercise, and from session to
session throughout the complete rehabilitative or training process. The
phenomenon of varying force output in a single movement is a consequence of the
biomechanics of the joint system and the physiological length-tension curve of
the musculo-tendinous unit. The actual muscular force output varies through the
range of motion based upon the interaction of the muscle and bones. Variable
force, then, is characteristic of virtually every human movement. Only
intelligent systems; such as the CES, can precisely accommodate the resistance.
Because of the body lever system, even if a muscle contracts with exactly the
same force throughout the movement, the resultant force on the end of the lever
arm such as the hand or the foot, varies at each position in the range of
motion. As the athlete or the patient's strength varies due to change in the
mechanical advantage of the linkage of his limbs, and also due to fatigue with
each subsequent repetition, the accommodating computerized system responds
instantly, automatically varying the force to match exactly that being applied
by the athlete or the patient. Only a computerized controlled system can achieve
ACES assists the coach or the physical therapist to determine the load
that should be put on a joint or limb for a particular exercise, or for a
particular rehabilitation session, as this is accomplished automatically by the
computer as the patient or athlete applies force to the exercise system. The
optimum rate of improvement for each patient or athlete is achieved using the
appropriate exercise intensity in each movement and exercise. By providing
automatic instantaneous accommodating resistance proportional to the patient's
or athlete's training progress, ACES is the safest and most effective
exercise method available. As the exercise apparatus develops resistance only in
proportion to the amount of force the patient applies, there is little danger of
over-stressing muscles, joints, or connective tissues.
ACCOMMODATING VELOCITY (ACCELERATION)
Just as a continuously varying force output is characteristic of natural
movement, so too is variable velocity. Nearly all movement involves
acceleration. When a javelin thrower releases the javelin, the angular velocity
at the shoulder joint accelerates from a speed of zero to about 4,000 degrees
per second and when a baseball pitcher throws a fast ball, his arm accelerates
to nearly 6,000 degrees per second. Just as in athletics, acceleration is also
involved in the natural activities of daily life. In walking for example, the
angular velocity about the knee alternately accelerates and decelerates between
zero and approximately 360 degrees per second and when running the velocity
approaches 1,500 degrees per second.
In order to train with similar neuromuscular patterns that occur in real life,
it is necessary to program the movement to this natural phenomenon. Only ACES established this today.
In restoring normal functionality then, acceleration and high velocity exercises
are essential components of the therapeutic or training process.
With the ability to program ACES to operate in specific velocities
throughout the range of movement from zero to over 1,000 degrees per second, ACES
distinguishes itself from any available modalities today. As the operating
velocity of ACES varies automatically throughout the range of motion, it
trains the neuromuscular system in the most efficient method to achieve optimal
results. ACES provides the appropriate resistance for each exercise, while
approximating the acceleration patterns encountered in natural movements. This
is the greatest achievement in intelligent exercise systems today and for the
future. ACES thereby approaches ultimate specificity in recruiting and
training the appropriate muscle fibers and neuromuscular pathways associated
with each position in the range of motion of an exercise.
SPECIFICITY OF MOVEMENT
In addition to providing programmable accommodating resistance and
programmable acceleration, ACES features unprecedented versatility in
duplicating natural movements. The overwhelming weight of contemporary
scientific evidence supports the advantage of those exercise patterns which
duplicate, as closely as is practical, the force and the velocity of the
particular movement. Only ACES can program the velocity and the force to
resemble the real movement associated in normal and super-normal athletic
performance. As far as rehabilitation, ACES is easily adaptable to each
individual patient, permitting simulation of natural movement patterns
previously unavailable with conventional resistance exercise systems. The value
of an exercise therapy prescription and the validity of performance data need no
longer be compromised by lack of movement specificity.
ACES is a resistance exercise system combining accommodating
resistance, acceleration, and specificity of movement for optimum progress of
the therapeutic and training process. As such, it is an invaluable tool for the
coach, physician, and therapist. But ACES is also much more. Being a computer
system, ACES displays and collects data and allows real-time motivational
feedback for the patient, athlete and the person that trains. All of the
relevant exercise variables are measured and integrated into a data base easily
understood for the athlete or the patient performance status. This database
accumulates past and present information for the force, velocity, work, power,
endurance and many more parameters related to the patient or athlete or normal
person functional capacity. All of these variables in exercise are interrelated,
and are measured concurrently with accuracy to characterize the performer.
Combined with a simplified computer data acquisition system, ACES
provides the most economical, efficient, and effective means of administering,
evaluating, and reporting athletic and rehabilitative exercise available today.

Exercise System. For the first time, there is an computerized exercise system
that has the capability to monitor an individual's present physical status,
ability, and daily progress while exercising.
