摘要

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:; <math overflow="scroll"><mrow><mi>P</mi><mo>=</mo><mfrac><mrow><munderover><mo>∑</mo><mrow><mi>i</mi><mo>=</mo><mn>1</mn></mrow><mi>C</mi></munderover><mo></mo><mrow><mi>Zi</mi><mo>×</mo><mi>Ni</mi></mrow></mrow><mrow><munderover><mo>∑</mo><mrow><mi>i</mi><mo>=</mo><mn>1</mn></mrow><mi>C</mi></munderover><mo></mo><mi>Ni</mi></mrow></mfrac></mrow></math> ;where C is the number of stroke types, Zi, with i between 1 and C, is the zone index, and Ni is the number of strokes executed per type of stroke i.
