Abstract
In an elliptical step exercise apparatus distance traveled can be approximated by determining the portion of the ellipse traversed by a foot pedal where the user applies force to the pedal. This portion can be considered equivalent to the amount of foot travel on a treadmill and modified as a function of speed to simulate the gait of a user at various speeds so as to provide an approximation of the distance traveled by a user as if he were running on a treadmill. This process can be further modified for use with an elliptical exercise apparatus where the stride length can be changed such that the simulated distance will be increased with increased stride length.
