Abstract: This exercise machine offers isometric and isokinetic exercise by regulating the speed of fluid flowing through the machine's hydraulic system. The consistent speed of the moveable elements on the machine prevents injury and enhances strength training of the targeted muscle groups by maintaining constant strain on those muscles throughout the exercise. This method incorporates both a PTCFC valve and a check valve device to compensates for both pressure and temperature variations within the hydraulic system over time. Additional machine elements allow for analysis of the user's strength through data and graphical displays.

Abstract: An isokinetic control module and method for incorporation on both new and existing exercise equipment. The control module replaces standard friction and hydraulic resistance components offering constant speed of the moveable elements of the machine rather than a selected resistance or weight. The constant user-generated resistance prevents injury and enhances strength training of the targeted muscle groups by maintaining constant strain on those muscles throughout the exercise. This method and device incorporates both a PCFC valve and a check valve device, removing all resistance the moment the user stops applying force to the machine. This enhances safety and facilitates the rapid return of the lifting element to its home position between repetitions. An optional graphical display is also disclosed.
