The effect of natural preferences on serving biomechanics: a new approach to the motor skills of tennis players

Research has demonstrated the existence of two 'natural preference' profiles in running. The objective of this study was to determine the influence of the natural preferences of ground (with a "posterior and flexion" movement) and air (with an "anterior and extension" movement) on the ball speed and impact position during the service of 19 professional players. The results allow to propose a new reading grid of the service technique to consider the preferential motricity of each player while respecting the biomechanical principles
