1. A sporting apparatus, which is capable of continuously outputting electricity, comprising:

  • a structure body;

    an endless belt disposed on the structure body and rotated by kinetic energy by a user;

    an electricity generating unit disposed in the structure body and configured to transform kinetic energy transmitted from the endless belt into electric power;

    a position sensing unit disposed in the structure body and configured to sense a position of the user on the endless belt so as to generate a sensing signal; and

    a modulation unit electrically connected with the electricity generating unit and the position sensing unit for receiving the sensing signal;

    wherein, the modulation unit comprises a DC/AC inverter, a current sensing element, an inductor and a semiconductor switch with a controller, the current sensing element is configured to sense an armature current outputted from the electricity generating unit and output a signal to the controller, and the controller is configured to control the duty ratio of the semiconductor switch to control the armature current, so that a counter torque of the electricity generating unit is adjusted when the armature current is adjusted according to the sensing signal for controlling the rotation speed of the endless belt.
