Analysis of the performance in the first serve in competitive tennis players under the effect of the induced aerodynamic flow

Abstract

This study analysed the product variables on the tennis serve of 12 experienced players, when constrained by an induced streamlined flow (EAI), delivered by an industrial ventilator. In order to obtain the serve accuracy, we use 2D analysis. Moreover, the ball's speed was measured by radar. The players performed 100 services at maximum speed and to the intersection point between the central and the service lines. The results showed no statistically significant changes in accuracy and precision between the control condition and the four EAI conditions. The results also showed prominent statistical changes in the serve speed for 6 among the 12 players. Concerning to the relation between the serve's speed and the accuracy, the results showed the existence of negative significant correlations for the speeds EA1, EAI3 and for random EAI. Lastly, the players' attempts had narrower accuracy and precision in the depth than in the serve direction.
