The number of loads is defined as a step count of a user stepping on the treadmill belt. The step count in a numeric form is outputted on a display panel.
The method of measuring the load exerted on the treadmill is one selected from the collection of a voltage feedback of the motor, a current feedback of the motor and an optical disk installed in the motor.
Therefore, users need not to wear a pedometer while doing exercise, but they can know about the step count directly from the treadmill while jogging on the treadmill. The invention not only provides convenience and avoids discomfort, but also saves the trouble of wearing a pedometer while doing exercises. In the meantime, it is not necessary for users to specially learn how to operate the treadmill or preset the treadmill, and thus the operation is very convenient.

The treadmill body 1 has a base 11, a rail 12 connected to the base 11, and an operating panel 13 connected to the rail 12 (for installing a load detection unit). The base 11 has a motor 2 and a treadmill belt 21. The motor 2 is installed on a side of the base 11, and the base 11 has two tracks 111, and an axle 112 is disposed separately at the front and the rear of the two tracks 111. The treadmill belt 21 is wound circularly between the two tracks 111 of the base 11 and also wound around the axle 112 of the two tracks 111, and the treadmill belt 21 is driven to rotate by the motor 2.
The load detection unit (this embodiment adopts a current detection circuit of the motor as a load detection unit which is not shown in the figure) is provided for detecting a load exerted on the motor 2, and recording the number of instant loads of the motor 2 at the same time.
The display unit 3 is electrically connected to the load detection unit and outputs the number of loads of the motor 2. The display unit 3 of this embodiment is a screen installed at the operating panel 13, and the load of the motor 2 is displayed in a numeric form on the screen.
The load detection unit is one selected from the collection of a voltage feedback detector of the motor, a current feedback detector of the motor, and an optical disk installed at the motor for detecting the load of the motor.

A continuous load is exerted on a motor by a user, such that the motor will be controlled to stop operating, if a load is determined as a continuous load; a discrete load is exerted onto the motor, such that a predetermined discrete time will be used to determine whether or not the user stops moving if a load is determined as a discrete load; the motor will keep on operating if another load shows up in the motor within a discrete time; and the motor will be controlled to stop operating if no more load is in the motor within a discrete time.
If a load is determined as a continuous load, it shows that the user has stopped jogging and stands on the treadmill belt or the treadmill belt gets stuck (by the user's bottom of a trouser leg, a shoelace or the user's body) and thus the motor 2 will stop immediately to prevent accidents.
If a load is determined as a discrete load, it shows that the user is using the treadmill. If the user stops jogging at this point, then there will be no more load within the suspended time and it shows that the user has left the treadmill, and thus preventing children or other people from standing on the treadmill suddenly and also preventing accidents.
