A method of processing data representing the performance of a tennis player in a display device includes: a) calculating, using data including physical quantities measured during a game period including one or several game sessions and transferred into a system for calculating of the display device, at least three parameters representing the player's performance during this game period, b) displaying, in the form of a diagram including one axis for each parameter, with the axes forming a star with several branches, points corresponding to the values of the parameters on the axes so as to form a generally polygon-shaped closed contour encompassing or passing through the points, and c) alternatively increasing and decreasing the surface area delimited by the closed contour according to a frequency of the variation calculated according to the effective game time of the player measured during the last game session of the game period.

Method for processing data representative of performances of a tennis player

Method for calculating a parameter (P) representing a tennis player's technical level during a series of strokes includes: a) determining, for each executed stroke, an impact zone of the stroke on the stringed zone of a tennis racquet used by the player; b) determining, for each executed stroke, the type of stroke, with the type being chosen from a list including at least two type of strokes; c) using the impact zones determined in step a) and types of strokes determined in step b) for the series of strokes, determining a zone index for each type of stroke; d) using the zone indexes calculated in step c), calculating the parameter value, using the following formula:
