Claim:
1. A method for representing the performance of a tennis player, the method comprising the steps of: a) the tennis player carrying out a series of strokes hitting a ball with a racquet comprising an integrated system for measuring game data, the system for measuring game data comprising sensors configured to measure the game data, the game data measured by the sensors comprising physical quantities including linear acceleration and angular speed of the racquet during the strokes; b) measuring, in each series of the strokes, game data using the system for measuring game data provided in the racquet, wherein the measured game data comprises the physical quantities including linear acceleration and angular speed of the racquet during the strokes; c) calculating, using the game data comprising the physical quantities measured at step b), during a game period comprising one or several game sessions, said each game sessions comprising series of strokes carried at step a), and transferred from the system for measuring game data into a system for calculating of a display device, at least three parameters representing the performance of the player during the game period, said parameters being chosen between at least a parameter representative of the power developed by the player during the game period, a parameter representative of the endurance of the player during the game period and a parameter representative of the technical skills of the player during the game period, d) displaying on the display device, in the form of a diagram comprising one axis for each parameter calculated at step c), with the axes forming a star with several branches, points corresponding to values of the parameters on the axes in such a way as to form a generally polygon-shaped closed contour encompassing or passing through said points, e) alternatively increasing and decreasing a 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.
