Strings (tennis)
In tennis, the strings are the part of a tennis racquet which make contact with the ball. The strings form a woven network inside the head (or "hoop") of the racquet. Strings have been made with a variety of materials and possess varying properties that have been measured, such as dynamic stiffness, tension retention, thickness (gauge), string texture (shape of the string), and rebound efficiency.
Turbo Tennis
Unlike regular tennis, games are set to a 30-minute time limit with a klaxon on the fifteenth minute to signify a change of ends from the next game onwards. If games are level after 30 minutes the winner is decided by a sudden death point, but there have been some changes and you have to win 2 out of 3 sudden death points to win the match. Other main differences include a 15-second maximum time limit for serves which, if exceeded, results in the player losing the point automatically; lets on serves are also played.
