variable resistance exercising device

variable resistance exercising device, 1976

an improved exercising device exercising legs of user includes frame member lever arm having 1 end pivotably attached thereto. lever arm extends downwardly portion of frame member pivotably connected, , pair of foot-engaging force transferring members mounted on lower end of lever arm. cable has 1 end pivotably connected near lower end of lever arm, passes around eccentrically mounted pulley , has other end connected weights. user lifts lower portions of legs, lever arm pivoted pull cable , weights attached thereto, thereby strengthening knee muscles of user. eccentrically mounted pulley varies resistance movement of user s lower legs increasing resistance , decreasing resistance in sinusoidal manner lower legs lifted pivot lever arm , lift weights. patent 4256302 a, 1981.

exerciser

an exerciser bar supported rotation , acts against hydraulic cylinder angle of bar , pressure in cylinder measured , fed micro computer which, using input data, controls cylinder pressure in accordance selected exercise program, micro computer providing outputs displays person exercising can monitor progress. patent 4354676 a, 1982.

passive programmable resistance device

passive programmable resistance device, 1985

a passive programmable resistance device uses closed loop feedback controlling resistance rotational or translational motion of object. 1 or more actual parameters, such force or position, measured , compared desired parameters. differences used provide control signal controls resistance movement of object. patent 4544154 a, 1985.
