A moving blade for a turbomachine with a central portion that is geometrically subdivided into four adjacent pressure-side zones disposed on the pressure side of the blade, and into four adjacent suction-side zones disposed on the suction side of the blade, the pressure-side and suction-side zones being distributed on either side of the skeleton of the blade, and the blade including in its central portion a pressure-side cooling circuit and a suction-side cooling circuit, the pressure-side cooling circuit including three radial cavities occupying three adjacent pressure-side zones, and the suction-side cooling circuit including three radial cavities occupying the four suction-side zones and the remaining pressure-side zone.
