The present invention offers itself as the result of an assembly, in a well defined order, of a multiple number of manufactured items and electronic/electromechanical devices, the latter being in turn governed by hardware and software information technologies, that are in their overall forming an instrument engineered to perform water-related human activities aimed at maintaining an optimum physical and psycho-physical condition. The hydrodynamic pool aims at being an instrument conceived for domestic as well as professional uses making it possible to practice such motory and therapeutic activities as well as relaxing activities identified as "stationary swimming", "massive hydrodynamic massaging" and "relaxing induced by hydrostatic suspension".
