For several decades, paddle tennis has become a mass sport in Spain and Argentina, and in recent years, it has quickly widespread in other European and Latin American countries. While in tennis there is a lot of research on the performance of rackets, there are still no studies on this sport. This work not only analyses the main constructive factors that influence the behaviour of a standard paddle racket, but also goes a step further and proposes the development of a new paddle racket with more sustainable materials, comparing the most significant characteristics of both solutions. To do this, various tests are carried out to characterise the overall stiffness of the paddle racket, determined mainly by the stiffness of the frame structure and to a lesser way by the stiffness of the strike face. In addition, tests are carried out to establish the rebound coefficient of the paddle racket, in order to locate the point where the transmission of forces between the ball and the racket is the lowest. In addition, numerical models are built and correlated with the experimental results to be used as a tool for the design of future paddle racket configurations. Finally, an analysis of the environmental sustainability of both rackets is proposed using the product life cycle analysis methodology and comparing the environmental impact in the carbon footprint.
