An exercise apparatus includes a frame and handles mounted on the frame and moveable by a user in opposite directions. The handles are coupled to a transmission so that movement of the handles by a user create rotational movement of a transmission input, movement of the handles in one direction creating rotational movement of the transmission input in one direction and movement of the handles in the opposite direction creating rotational movement of the transmission input in the opposite direction. The transmission couples the transmission input to a resistance means, such as an eddy current resistance device, in a manner to provide a different resistance to rotation of the transmission input depending upon the direction of rotation of the transmission input. Thus, the resistance to rotational movement of the transmission input in one rotational direction is greater than it is in the opposite rotational direction. This coupling can be accomplished by converting rotational movement of the transmission input in opposite directions into an output having only one direction of rotation and coupling the output to a single resistance element, or the transmission can couple a shaft that rotates in opposite directions to two resistance elements so that rotation in one direction is resisted by one resistance element and rotation in the opposite direction is resisted by the other resistance element.

Exercise machine

Apparatus for selectively testing muscle strength and range of motion of a body part of a patient includes a housing having at least one contact area, and preferably two spaced apart contact areas, for contacting and aligning the apparatus with a body part to be tested for range of motion and an inclinometer to measure the angle of the apparatus and produce an angle signal indicative of the measured angle. The difference between the angle measured at one extreme of movement of the body part and at the other extreme of movement provides a measure of the range of motion. A force applicator coupler couples a force applicator to a force transducer to measure muscle strength. The force transducer produces a force signal indicative of the force applied by the force applicator to the force transducer. Interface circuitry which preferably includes a microprocessor processes the angle signals and the force signals to produce output signals to a display in the apparatus and, if desired, to a computer programmed to receive such signals.

Device for measuring force and angles

Exercising apparatus is constructed with operating mechanism that includes a stationary platform elevated above user-accommodating level sufficiently to support a stack of weights in a position corresponding approximately with the position of the user's head, so weight selection is facilitated and so such mechanism can be attractively housed. A weight carrier includes weight connection members rising from an elevator platform that is adapted to be raised by muscle power of the user along with a user-selected number of weights connected thereto.
