ABSTRACT:
A training apparatus with a visual display for a swimmer. In a first aspect of the invention, an impeller mounted in a module worn by a swimmer is driven by a forward motion of the swimmer. A pair of permanent magnets mounted on opposite vanes of the impeller act on a magnetic field type transducer to produce a pulsating voltage which varies directly in frequency with the speed of the swimmer. The output of the sensor is processed and transmitted to a visual display worn by the swimmer. Changes in the visual display enable the swimmer to identify the effect of changes in the swimmer's form and/or movement on his performance. In a second aspect of the invention, a revolving magnet produces a pulsating voltage in a coil of wire. The output of the coil is processed and transmitted to a visual display worn by the swimmer.
