Davis Cup: 5 Things You Didn’t Know About Tennis

Do you like tennis? Follow tournaments such as the Australian Open, Roland Garros, Wimbledon, and especially the Azzurri in Davis Cup? Here are five facts about the game of tennis that you probably didn’t know.

1. How long can a tennis match last? Tennis, like other sports, has no time limits. To win the match, the player must win a certain number of combos, no matter how long it takes. Most tennis matches last between two and three hours. Some matches extend even further, especially since 1973, when the FIFA introduced the tiebreak rule. But there are exceptions.

2. Why are tennis balls “hairy”? The fluff allows for better control of the shot by the player: if it is not there, the ball will scatter away uncontrollably, thanks to which the strings of the racket hold the ball for a moment, compressing it and allowing the tennis player to set the ball. Ball .. desired and to highlight the effects.

The second function of the hair is to increase the ball’s resistance to the air, reduce its speed, and reduce its bounce. In fact, when worn and now fluff-free balls are used, at the moment of rebound they tend to slide farther onto the playing surface. During the manufacturing stage, the fluff is made of felt that covers the rubber core, thanks to powerful jets of steam.

3. Why do tennis players look at balls before serving? To choose which one to use among those available, and not just, as you might think, the newest. In professional tennis matches after 7 matches (and every 9 matches from the first change onwards), players send out new balls and whoever is playing the racket usually warns the opponent by holding their hand up high and pressing into the punch a still-clean ball.

These changes are to be expected due to recoil and suffering from violent blows from rackets and ground, balls It shrinks quickly, softens and rebound properties vary. As these lose weight, many tennis players take advantage of pitch inversion (available for every two games) to alter their racket, not because the strokes relieve the tension of the strings themselves, but rather to choose the instrument whose strings are calibrated more appropriately to the level of wear that they have reached. Mechanism of balls used at the moment.

4. What plastic pieces do tennis players put on the racket? so called dampers Shock absorbers are small, pin-like pieces of plastic that many tennis players attach to the strings of their racket in the part closest to the handle in order to dampen the vibrations caused by impact with the ball. Known in Italian as rubber ropes or pads, they are very useful for protecting the wrist, elbow and arm joints, especially for tennis players who rely on strength for their game. Some of the most technical athletes, including Roger Federer, believe that with inhibitors they lose sensitivity in the blow, so they prefer not to use them.

Until the 1990s, the function that today’s rubber pads perform was attributed to the common elastic bands that keep tendons in tension by absorbing part of the vibrations, while more recently, some manufacturers have put rackets on the market with “standard vibration dampers”, which are gaskets Elastics placed at the base of the central vertical ropes.

5. Why do tennis courts have red clay? traditional red earth for tennis courts In which some of the most important tournaments in the world such as Roland Garros and Internazionali d’Italia are played, they are obtained from the waste from the production of bricks used in construction. The finer the tearing of the material, the better the quality of the mantle (scattered on the ground and clay).

In addition to the red earth, in some leagues in the United States, a certain green land (called Hawaii) is used, which is obtained from the fracturing of basalt. Then there was the blue ground, artificially colored for sponsorship and television reasons (the yellow ball popped more) and tested at the 2012 Madrid Championship, an experience that was not repeated, anyway, because this ground was very slippery and precarious. for athletes. Finally, there are fields of brown, yellow or gray clay, but not all of these are professionally used.
