ABSTRACT:
An exercise or therapy apparatus for use in a pool of water utilizes a stationary frame and an impeller section including a user-operable impeller wheel rotatably attached to the frame for rotation about an axis of rotation. Pedals are connected to the impeller wheel enabling the turbine wheel to rotate about its axis of rotation in conjunction with the movement of the user's feet as a cycle-type exercise or therapy device. The impeller section includes an inlet positionable within the water of the pool, and the impeller wheel is adapted to draw a stream of water into the inlet of the impeller wheel as the impeller wheel is rotated about its axis of rotation. A valve is associated with the impeller section for controlling the quantity of the stream of water which is permitted to flow into the impeller section by way of the inlet when the impeller wheel is rotated to thereby alter the resistance to the rotation of the impeller wheel.
