The Ariel Computerized Exercise System (CES), invented by Dr. Gideon Ariel, heralds a new era in physical rehabilitation, research, and conditioning. Ariel CES is the only system available that automatically monitors, controls, and modifies resistance and velocity while the person is exercising. It does this safely and efficiently, constantly adjusting itself to accommodate each person's unique capabilities or limitations. Ariel CES also provides extensive and accurate measurements of movement, strength, and endurance with the capability for storage and subsequent comparison and analysis of the individual's performance.

The Intelligent System

"That's why we call it the "Intelligent System" for rehabilitation and fitness. Arid CES senses and responds directly to an individual's performance in real time. In other words, the computer is able to control your movement and adjusts to your effort while you exercise. Not only does the Ariel CES sense and respond to specific motions, it also interacts with the individual, providing immediate visual and audio feedback during exercise.

At the heart of Arid CES's "intelligence" is a state of the art microcomputer system. The computer and its unique software assume the responsibility for controlling the precise force level, speed of movement. and temporal sequence to achieve a specific pattern of exercise. Unlike other systems. Arid CES has the ability to adjust and modify its assignment throughout the entire exercise session.

The monitor provides complete performanceinformation on a continuous basis duringexercise. llmuting totals of work. repetitions.and elapsed tint' are maintained.

The "user-friendly" screen instructions permit anyone to operate the system. even individuals who have never used a computer.

The average curve plot (solid graph) shows theaverage exercise values measured for both theup and down strokes. Optional comparisons toprevious performance (red line), or to an"ideal" performance goal (gre(,n line).may also he included.

Flexibility of Use and Function

Key to the Ariel Computerized Exercise System is the flexibility it offers. Isotonic. isokinetic. or isometric exercise, or any combination of these exercise modes can be performed. In addition, the Ariel CES can control and measure velocity. resistance, power. work output, fatigue level, duration of exercise. or combinations of all five.

Another major value of the Ariel CES is its ability to run manual and pre-programmed sequences of exercises as well as customized individual exercise sequences. A physical therapist can follow prescribed testing or training protocols for patients or can create and program unique procedures for specifically desired routines.

In fact, Ariel Computerized Exercise System encourages innovation and creativity ... because the Ariel CES can adjust the speed or the resistance of an exercise throughout its range of motion ...because the Ariel CES allows the application of an isometric contraction at a selected point within a movement ... because the Ariel CES response can be controlled throughout the entire range of motion ... the possibilities are endless.

The Ariel CES is comprised of these basic components: The Multi-Function Exercise Station The Arm. Leg. Back Exercise Station The Computer Console The Monitor

The System Software The Printer (Optional)

• Accommodate resistance until the individual reaches a prescribed level of fatigue during endurance training
• Display performance goal target as an incentive during exercise
• Store and retrieve performance data
• Compare current and previous performance data in color graph. chart or tabular form
• Generate performance profile of average and maximum exercise results for each repetition and for both up and down directions
• Illustrate in graphic format the force, work, power, and fatigue in relation to time, bar position, and lifting pace
• Calibrate dynamically force and velocity through the entire range of motion and verify results

What the CES Can Do

For the operator, the Ariel Computerized Exercise System performs many critical functions. including the ability to:

• Rehabilitate and condition
• Measure and diagnose
• Record and evaluate results
• Control and monitor velocity in each direction independently
• Control and monitor resistance in each direction independently
• Program the pyramiding of resistance or speed in each direction
• Program the range of motion in each direction
