The system defines at least one axis of rotation that is to assume a position corresponding to the joint of the operator. A device is carried by the garment and designed to operate so as to compensate the resistive moments that act on the joint during the effort exerted by the operator. A compensation device is provided equipped with a rotational assembly, which has a neutral position and is able to determine a pre-set plot of the assisting torque that is a function of the angle of rotation of the joint. The compensation device may include a tension regulation device to regulate a moment obtained about the joint of the operator.
