Abstract
A treadmill with a fan that directs an airflow toward a user is provided. A fan controller receives an input signal corresponding to a belt speed of the treadmill belt and converts the input signal into an output signal to the fan to control the speed of the airflow by adjusting the rotational speed of the fan. The fan controller is calibrated to adjust the fan speed so that the air speed experienced by the user matches the belt speed, thereby accurately simulating the airflow and air resistance that the user would experience when running over ground at the same speed that the treadmill belt is moving.
