The invention measures speed relative to the air in human-propelled motion, such as on a bicycle (1, 8). Any one of several types of anemometer (5) can be used for this purpose, ground speed determined by wheel (4, 12) rotation, cadence from pedal rotation, altitude, temperature, heart rate, and elapsed time, to provide an integrated picture of the athletic performance. It is especially useful in determining the effect of wind (2) on performance, and for obtaining a readout in real time of any favorable or adverse effect of wind, or the power output and calorie consumption. The measurements made in real time may be stored in the device of the invention and later downloaded into a computer for analysis, review and training purposes. The invention also comprises methods for calibrating a device to correct for individual variations in aerodynamic characteristics. |
