The invention relates to a novel blade design which does not exceed the permitted stresses for particular loads, especially as a result of the centrifugal force and which at the same time, allows the turbo-machine (3) to function with a high degree of efficiency. To this end, an inventive moving blade (1) for a turbo-machine (3) consists at least partially of a cellular material (5), especially a foamed metal (21). Said cellular material (5) can be provided e.g. in the hollowed-out part (7) of the moving blade (1).
