Tennis is the best known racquet sport in which two or four players compete on a court divided by a net. It is considered a complete, harmonious sport that gives great benefits to health, physical and psychological well-being. The aim of the game is to throw the ball in the opposite field, in specific areas delimited by lines (the position of the lines is based on the type of match). The score counts when the ball ball touches the ground in the opponent’s field and when the opponent cannot respond.
