"The biggest drawback of asphalt courts is not that they crack, for even a post-tensioned slab may crack from shrinkage or even develop minor structural cracking, but that the cracks continue to widen year after year," says Kolkmann. "I have seen asphalt courts with cracks as wide as 2 to 3 inches, making them a hazard to the players. The advantage with a post-tensioned slab is that it will not allow the crack to widen, but will keep it compressed to a very thin line."

Tennis also became popular in France, where the French Championships dates to 1891 although until 1925 it was open only to tennis players who were members of French clubs. Thus, Wimbledon, the US Open, the French Open, and the Australian Open (dating to 1905) became and have remained the most prestigious events in tennis. Together these four events are called the Majors or Slams (a term borrowed from bridge rather than baseball).

Good Vibrations: Beginners need not apply with this oddly-shaped modern tennis racket. The 98 square-inch head has the same iconic – which is to say strange – shape that Yonex has been pushing for years, yet this one feels much more normal for intermediate and advanced players. The sweet spot is larger than usual, but still smaller than many choices. It’s a bit weighty at 11.5oz but Yonex seems to have used the extra weight to good effect with their Dual Shut System which uses the grommets near the handle to dampen bad vibrations for cleaner hits. It actually seems to come alive the harder you swing so it works well for playing an aggressive defense. While it shines against power hitters, trying to get the top spin to make a really heavy ball just won’t work. [Purchase: $199]
Weights of a racket also vary between 7 ounces (200 g) unstrung and 12.6 ounces (360 g) strung. Until the 1980s, rackets weighted at "medium" were produced. "Heavy" rackets were produced during the height of the wood era (e.g. the 1960s), very sparingly. The "medium" weight is heavier than any of the rackets produced since it was discontinued by companies. Many professionals added weight to their rackets to improve stability. Many continue to do so. Pete Sampras added lead tape to make his racket have a 14 ounces (400 g) weight and Venus Williams is known for using a frame modified to be quite heavy, in terms of the recent times average. By contrast, Andy Roddick surprised many when he said he used a stock Pro Drive series model, series of racket which was light when compared with the rackets used by most top professionals. In both recreational and professional tennis, the trend has been away from heavy rackets and toward lighter rackets, despite the drawbacks from light rackets, such as increased twisting. Lawn tennis rackets originally flared outward at the bottom of the handle to prevent slippage. The rounded bottom was called a bark bottom after its inventor Matthew Barker. But by 1947, this style became superfluous.[clarification needed] More mass gives rackets "plow through", momentum that continues once the player has managed to get the racket into motion and which is more resistant to stoppage from the ball's momentum. This can give the perception that the racket produces shots with more power, although this is complicated by the typically slower stroke production. Higher mass typically involves a slower swing but more energy to execute the swing. More mass also provides more cushioning against ball impact shock, a source of injuries such as tennis elbow. However, high racket mass can cause fatigue in the shoulder area. Typically, it is safer for the body to have higher mass. More mass, additionally, provides more stability. It makes the racket more resistant to twisting forces and pushback. The drawbacks are that heavier rackets have lower maneuverability (reducing reaction time) and require more energy to move. As a racket gets heavier, the player finds it increasingly difficult to do fast reaction shots such as quick volleys and returns of serve. However, the additional mass can help with return of serve, in particular, by making the racket much more resistant to twist from a high-powered service. Light rackets have the additional drawback of making it easier for beginning players to use inappropriate wrist-dominant strokes, which often leads to injury. This is because poor stroke mechanics can be much easier to produce with a lightweight racket, such as in using one's wrist to mostly swing the racket. An extremely typical mistake beginning players make is to choke up heavily on the racket (to try to compensate for twist from a light racket, as well as too high racket angle upon impact) and use the wrist too much. The only professional well-known player to have had success with a strongly choked-up grip is Zina Garrison.
Historians believe that the game's ancient origin lay in 12th century northern France, where a ball was struck with the palm of the hand. Louis X of France was a keen player of jeu de paume ("game of the palm"), which evolved into real tennis, and became notable as the first person to construct indoor tennis courts in the modern style. Louis was unhappy with playing tennis outdoors and accordingly had indoor, enclosed courts made in Paris "around the end of the 13th century". In due course this design spread across royal palaces all over Europe. In June 1316 at Vincennes, Val-de-Marne and following a particularly exhausting game, Louis drank a large quantity of cooled wine and subsequently died of either pneumonia or pleurisy, although there was also suspicion of poisoning. Because of the contemporary accounts of his death, Louis X is history's first tennis player known by name. Another of the early enthusiasts of the game was King Charles V of France, who had a court set up at the Louvre Palace.
