ABSTRACT:
The specification discloses a self propelled stress testing apparatus for providing graded levels of exercise and for measuring human energy output. An adjustable frictional load calibrated in terms of patient weight and operatively coupled to a pair of translational platforms provides the exercising drag force to a flywheel against which the effort of the user is applied. Reciprocal exercising motion applied to the translational platforms is converted into rotary motion via a pair of unidirectional sprockets. Alternative embodiments employing bifilar and elastically centered slideable guide platform configurations are disclosed as well as special adaptions for use in a weightless space environment.
