Abstract:
1. An electric treadmill comprising a tread base, a handrail, an electric console, a motor, a running belt and a rear support, said motor bringing a drive belt into rotation which drives a front roller, said running belt being placed around said front and rear rollers, thereby creating an endless rotation by means of the operation of said motor; wherein, based upon a central reference point, said tread base neighboring upon said running belt is provided with sensing lines for acceleration, sensing lines for deceleration both of which are arranged one after the other, and wherein, when the runner touches one of the sensing lines by altering a light wave or an acoustic wave from a sensing element, a CPU located within said electric console gives a command according to the sensing line touched to accelerate or decelerate said motor so that an immediate control of the rotational speed of said running belt is achieved, wherein said sensing lines for acceleration are divided into at least one additional accelerating sensing line and a basic accelerating sensing line and said sensing lines for deceleration are divided into at least one additional decelerating sensing line and a basic decelerating sensing line.
