1. A method of measuring swimming technique during actual swimming comprising:
- measuring a pressure differential between the palm and the back of a swimmer'"'"'s hand during actual swimming, over a period of time transmitting said pressure differential in the form of radio waves to a remotely located receiver;
plotting a curve of the pressure differential over the time period; and
calculating an area under the curve as a measurement of swimming technique.

Abstract
A method and device for measuring swimming technique utilizes a pressure transducer mounted to the hand of a swimmer. A measurement is taken of the pressure differential between the palm and the back of the swimmer'"'"'s hand is measured during swimming and is plotted against time with the help of a microcomputer. An area under this curve is calculated and gives a measurement of the swimming effectiveness.
