Abstract
An instrument ('artificial athlete') for characterizing, from the biomechanical standpoint, a treading surface, such as natural grass cover or synthetic grass flooring, is configured for: dropping a weight from a given height on the surface, producing the conversion of kinetic energy of falling of the weight into deformation energy of the surface, the deformation energy being able to be restored by the surface to the weight, bringing about its return/bouncing back upwards; and detecting at least one parameter representing the process of restitution of the deformation energy by the surface to the weight, the parameter identifying the characteristics of tread of the surface.
