Sporting apparatus and control method thereof

Abstract

A sporting apparatus comprises a structure body, an endless belt, an electricity generating unit and a position sensing unit. The endless belt is disposed on the structure body. The electricity generating unit is disposed in the structure body and transforms kinetic energy, which is transmitted from the endless belt, into electric power. The position sensing unit is disposed in the structure body and senses a position of a user on the endless belt so as to generate a sensing signal. An armature current of the electricity generating unit is adjusted according to the sensing signal for controlling a rotation speed of the endless belt. A control method of the sporting apparatus is also disclosed.
