Abstract
A training method with a visual display for a swimmer. A compact apparatus is mounted on a mid-portion of a swimmer for generating a fluctuating signal which varies in frequency according to the speed of the swimmer. The swimmer changes his form and/or movement to vary the frequency of the signal. The signal is processed to produce a fluctuating visual signal which is communicated by a visual display to the swimmer to immediately inform him whether the change in form or movement has increased or decreased his speed.
