Watts Measurement - Star Trac Turbo Trainer Owner's Manual

Watts Measurement

The console does not directly measure or estimate watts power. But information on watts produced by cycling on the Turbo Trainer can be
seen on the chart below, where RPMs generated by the flywheel are correlated to watts. Values were generated by the use of a computer
controlled Dynamometer which was coupled to the crank of the Turbo Trainer.
RPMs are displayed on the horizontal axis with watts displayed on the vertical axis. Below the RPM values on the horizontal axis are the
actual watts measurement for that RPM value. For example, at 30 RPMs the watts are 30, whereas at 55 RPMs the watts measurement is
100.
The curvature of the graph is due to the exponential increase in the isokenetic resistance of the movement of air across the fan wheel.
Therefore, faster the fan wheel is turned, the higher watts generated.
