ABSTRACT:
A bodyworn apparatus that senses and measures the hydrodynamic thrust generated by a swimmer's hands as he strokes his hands through the water. The apparatus consists of pressure sensitive transducers that convert the amount of thrust into electric signals that are fed back to the swimmer in terms of an audio tone with tone frequency varying as a function of thrust and/or are transmitted to a recording instrument calibrated to quantitatively meter and record the thrust generated by the swimmer's arm strokes.
