ABSTRACT:
A device for enabling testing of a person's physical condition, by enabling easurement of the energy expended by the person to be tested thereby, in manually maintaining rotation of a flywheel in a stationary bicycle, against resistance applied to the flywheel, for use in determining the efficiency of the person's body in using energy, as an indication of such person's physical condition.
The device is adapted to overcome inertia of the flywheel, from rest to a selected speed of rotation thereof, in an efficient and effective manner, prior to the onset of the test. Upon the onset of the test, with inertia in the flywheel having been non-manually overcome, the person to be tested is to manually maintain rotation of the flywheel, against resistance applied thereto, by manually rotating pedals operably connected to the flywheel.
The device includes a non-manual inertia overcoming mechanism. In one embodiment, the mechanism includes a motor, the drive shaft of which is rotatably mounted in the bicycle frame and operably connected, through sprockets and a chain, to a sprocket, driven by the motor drive shaft through such operable connections. The driven sprocket is engaged with a belt, which is operably connected to the flywheel, for selectively driving the belt and flywheel thereby.
In another embodiment, the mechanism includes a motor, the drive shaft of which is rotatably mounted in the bicycle frame, with the flywheel mounted thereon, for selectively and non-manually overcoming inertia in the flywheel.
