Abstract
A treadmill has a belt provided with a running surface and rotated in a predetermined direction at a set running speed, wherein a foot landing on the running surface is detected, a landing time distance between landing times is measured, and a stride is calculated from the running speed of the running surface and the landing time distance measured and indicated or recorded on an output device.
