Abstract
An apparatus and control system for establishing and maintaining a user selected magnitude and direction of pneumatic resistance provided by exercise equipment includes at least one electrically controlled regulator for admitting air to and releasing air from the pneumatic system, transducer for measuring air pressure within the system and providing a corresponding signal, potentiometer for setting and monitoring system pressure in response to signal input from the transducer, air accumulator tank, and pneumatic piston cylinder assembly. The apparatus may also include at least one user controlled electrically switchable four way valve for providing bi-directional resistance. The apparatus is adaptable for providing unilateral or bilateral exercise movements, with or without bi-directional resistance, and can be used to provide range of motion exercise without resistance.
