"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."

This level and the pro level share a lot of similarities simple because things have gotten a lot competitive in recent years. NCAA level players sometimes go pro after graduating college like John Isner. So, they accept nothing but close to perfection from young aspirants. There are NIAA colleges that offer some partial scholarships and they do not have the same rigorous requirements as the NCAA but often times they are very small colleges which are always the second choice for most students.

The modern tennis court owes its design to Major Walter Clopton Wingfield. In 1873, Wingfield patented a court much the same as the current one for his stické tennis (sphairistike). This template was modified in 1875 to the court design that exists today, with markings similar to Wingfield's version, but with the hourglass shape of his court changed to a rectangle.[50]

Modular tile systems are the newest cushioning option on the market and offer the benefits of easy snap-together installation, long service life, and minimal maintenance. These systems feature interlocking, 12-inch square tiles made of high-impact polypropylene. The tiles rest slightly above the base surface to allow for better drainage and eliminate puddling. The downside of this cushioned comfort is the cost, which can run as high as high as $3 per square foot installed (or over $21,000 for a 60 x 120-foot tennis court).
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.
Before heading to a court, make sure that you’ve read our rules and regulations. Follow our permit rules, wear smooth-sole tennis shoes, and use a maximum of six tennis balls on each court. Most courts are open from 8:00 a.m. to dusk, except at Central Park where courts open at 7:00 a.m. and Randall's Island where courts open at 7:00 a.m. and close at 7:00 p.m.
The origin of the term "racket" is unclear. According to a popular belief first published by tennis player Malcolm Whitman in 1932, the expression comes from the Arabic term rahat al-yad, meaning "palm of hand".[4] Modern research however, holds this thesis in a highly questionable light.[5] Instead, the term is more likely to be derived from the Flemish word "raketsen" which is itself derived from Middle French "rachasser", meaning "to strike (the ball) back".[6]
Tennis is played on a rectangular, flat surface. The court is 78 feet (23.77 m) long, and 27 feet (8.2 m) wide for singles matches and 36 ft (11 m) for doubles matches.[48] Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. It is held up by either a metal cable or cord that can be no more than 0.8 cm (1⁄3 in).[49] The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (0.91 m) high in the center.[48] The net posts are 3 feet (0.91 m) outside the doubles court on each side or, for a singles net, 3 feet (0.91 m) outside the singles court on each side.
So, a lot of people are very competitive in everything they try. They want to have the best business if they get into it, they want to be the best at their job when they get it, etc. If you are that sort of person and you look for excellence in your game but do not want to commit professionally to this then it is going to take an upwards of 5-10 years to play at some decent level like club level or USTA sponsored tournaments.

I too began tennis as a retirement activity at age 65. I am now 74 and have found that I can only play with people at my age and level. I get nothing from watching a young, experienced player smash the ball past me and standing in front of every shot I hit, no matter where I aim it. If you would like to correspond and chat and compare notes further, I am at alsal38@me.com. My name is Al Salganick.

Although Kolkmann admits that concrete courts cost substantially more initially than asphalt, an asphalt surface often requires more frequent and costly upkeep over its lifespan to repair cracking and settling. "Through our own recordkeeping, we estimate that an asphalt court will be unavailable for play, due to repairs being made, for about 100 days over a 20-year period," he says. "During this same time, a post-tensioned slab would be down for about 20 days. In our climate in the upper Midwest, repairs can only be done in the summer, when everyone wants to play. For a private court, the downtime may not be as crucial. But for a club, it can be a substantial unknown cost in lost revenue."
Vibration dampeners (also sometimes known as "gummies") may be interlaced in the proximal part of the string array, to reduce the percussive sound of the ball hitting the strings and/or to reduce perceived vibration. They do not, however, reduce impact shock significantly, so they are of no safety value.[13] Some professionals, such as Andrei Agassi, used rubber bands instead of specialized dampeners. Dampeners come in two main types. The first uses the two central main strings to hold it in place. The second is sometimes called a "worm" and it is woven between many of the main strings. Dampeners are nearly always placed very near the bottom of the racket string bed.

Takes All Comers: Since most of the best tennis rackets run in the $200 range, we wanted to give the entry-level buyer something that would give them quality and control without ruining their budget. Prince rackets generally cater to a slightly less affluent clientele, but they still make incredible, versatile stuff for the price. Their original Red is a great place to start. No matter what kind of play style you have, the large sweet spot sunk into the friendly 105 square-inch head is a bargain at twice the price. The 9.9oz weight works well for anyone with tennis elbow or the casual player who needs to adjust to moving a racket around. Whether you are a baseliner needing speed and power or a net player that wants size, the Red is a very solid, if not particularly flashy or sexy choice. [Purchase: $80]

In the U.S. in 1874 Mary Ewing Outerbridge, a young socialite, returned from Bermuda with a sphairistikè set. She became fascinated by the game of tennis after watching British army officers play.[18] She laid out a tennis court at the Staten Island Cricket Club at Camp Washington, Tompkinsville, Staten Island, New York. The first American National championship was played there in September 1880. An Englishman named O.E. Woodhouse won the singles title, and a silver cup worth $100, by defeating Canadian I. F. Hellmuth.[19] There was also a doubles match which was won by a local pair. There were different rules at each club. The ball in Boston was larger than the one normally used in New York.
