ABSTRACT

The type of the tennis court’s ground surface determines the rebound angle and velocity of the ball, and also influences the displacements of the player (Roetert and Groppel, 2001). Quality of a ground surface may be evaluated by its stiffness and its slipperiness, and these are different between slow surfaces (i.e., clay) and fast surfaces (Le., Greenset®). Slow surfaces, named rugged surfaces, reduce the speed of the ball and induce a higher and slower rebound, in contrast to fast surfaces.
