The concrete slab should be placed at a thickness of at least 4 inches, or 5 inches if subject to repeated freeze/thaw cycles. Munson's post-tensioned slabs are a minimum of 5 inches thick, with the post-tensioning cables spaced 3 feet apart. Before installing the slab, Munson lays down two layers of 10-mil polyethylene sheeting to reduce drag as the slab shrinks upon curing and to serve as a moisture-vapor barrier.
You and your group of friends just started to play tennis just to have a little fun with it. You do not plan to compete or anything. Your main focus is to have fun and have a good time with your friends. You do not care about whether you have the proper technique or the form, you just want the ball to keep in play and have some long and exciting rallies with your group of friends.
The players (or teams) start on opposite sides of the net. One player is designated the server, and the opposing player is the receiver. The choice to be server or receiver in the first game and the choice of ends is decided by a coin toss before the warm-up starts. Service alternates game by game between the two players (or teams). For each point, the server starts behind the baseline, between the center mark and the sideline. The receiver may start anywhere on their side of the net. When the receiver is ready, the server will serve, although the receiver must play to the pace of the server.
I am one of the least coordinated people on the planet and so going to a municipal court to spend my spare time picking up balls has never really appealed. The whole ‘catching and throwing of balls’ thing is just something that completely passed me by as a kid; if you’re athletic enough, people tend to leave your absolutely chronic lack of motor control.
To begin to learn to play tennis, you need to understand its unusual scoring method. As a tennis beginner, you must understand how to keep score. Scoring doesn’t start with 1 or 0 — it starts with the term “love”, equivalent to zero. The first point is then 15 followed by the next point, 30, and the next point, 40. The following point is the winning point and it’s called game point or set point or match point — depending on which you are playing.
Tennis balls were originally made of cloth strips stitched together with thread and stuffed with feathers.[44] Modern tennis balls are made of hollow vulcanized rubber with a felt coating. Traditionally white, the predominant colour was gradually changed to optic yellow in the latter part of the 20th century to allow for improved visibility. Tennis balls must conform to certain criteria for size, weight, deformation, and bounce to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 65.41–68.58 mm (2.575–2.700 in). Balls must weigh between 56.0 and 59.4 g (1.98 and 2.10 oz).[45] Tennis balls were traditionally manufactured in the United States and Europe. Although the process of producing the balls has remained virtually unchanged for the past 100 years, the majority of manufacturing now takes place in the Far East. The relocation is due to cheaper labour costs and materials in the region.[46] Tournaments that are played under the ITF Rules of Tennis must use balls that are approved by the International Tennis Federation (ITF) and be named on the official ITF list of approved tennis balls.[47]

In the early 1980s, "graphite" (carbon fibre) composites were introduced, and other materials were added to the composite, including ceramics, glass fibre, boron, and titanium. Some of the earliest models typically had 20% or more fiberglass, to make them more flexible. Stiff rackets were typically not preferred by most players because of their familiarity with the comfortable softness of wood. These early models tended to be very flexible and not very powerful, although they were a power upgrade over wood and metal rackets. Wilson created the Jack Kramer Pro Staff, the graphite version of the wood racket of the same name extremely popular in the late 70's and early 80's. This was the origin of the extremely influential Wilson Pro Staff 85. Chris Evert's first graphite racket was this Jack Kramer version, which had 20% fiberglass. It was not a market success and she, along with everyone else, quickly replaced it with the stiffer Pro Staff 85, which had 20% kevlar. It used the same mold and had the same braided graphite, but offered a very noticeable improvement in power. The very popular Prince original graphite, an oversize in its most popular form, was also quite influential and used by many pros, especially as juniors. Jennifer Capriati and Monica Seles, for instance, used the Prince graphite to contest their influential Wimbledon match in 1991 that has often been hailed as the beginning of the power baselining game in the WTA, although that claim is somewhat hyperbolic and is, in large part, due to the mistaken impression that the players were hitting much harder when, in fact, the rackets were more powerful. However, the very large head size, when compared with the midsize and, especially, the old "standard" size, made it easier to produce power. The racket also had an open string pattern. The Prince "original" graphite name is rather a misnomer, as it went through some significant design adjustments over its lifetime. For instance, the truly original model had a reverse teardrop head shape, something no subsequent versions had. Stiffer composite rackets, when compared with the first and second generations of graphite composites, are the contemporary standard. The last wooden racket appearing at Wimbledon appeared in 1987, long after they were abandoned by practically all professionals.[17] Borg tried to stage a comeback with his standard wood racket, after his premature retirement, but it quickly ended in failure, as the standard wood was no match when placed against a stiff midplus graphite. It is also commonly argued that Chris Evert would have been able to beat Martina Navratilova during the latter's most dominant period if she had switched from her wood racket years sooner. Additionally, the last influential wooden racket, the Prince Woodie, had layers of graphite to increase its stiffness and was an oversize. It was used by Tommy Haas, Gabriela Sabatini, and quite a few others. It offered very little power but did offer much more surface area than a standard-size wooden frame. Sabatini found it helpful, as compared with smaller rackets, due to her production of heavy topspin. The only woman to beat Martina Navratilova in 1984, Kathleen Horvath, used the Prince Woodie, one of only six losses Navratilova suffered in a three-year stretch involving 260 matches.[18]
By the 1960s, Budge and others had added Pancho Gonzales and Lew Hoad to the list of contenders. Budge reportedly believed that Gonzales was the greatest player ever.[99] Gonzales said about Hoad, "When Lew's game was at its peak nobody could touch him. ... I think his game was the best game ever. Better than mine. He was capable of making more shots than anybody. His two volleys were great. His overhead was enormous. He had the most natural tennis mind with the most natural tennis physique."[100]

You’ll need a racquet with its own case. For a beginner, all you really need to do is check to make sure your hand fits comfortably around the handle. The racquet shouldn't feel like it's too heavy to move, but it also shouldn't feel like it weighs nothing. There are also men's and women's racquets, but you should prioritize fit over gender in most cases.

Van Alen called his innovation a "tiebreaker", and he actually proposed two different kinds or versions of it: best-five-of-nine-points tiebreaker and best-seven-of-12-points tiebreaker.[23] The first lasts a maximum of 9 points, and awards victory in the set to whichever player or team first reaches 5 points – even if the other player or team already has 4; the margin of victory can be a single point. Because this "9-point" tiebreaker must end after a maximum of 9 points, even if neither player or team has a 2-point (or greater) margin, Van Alen also called it a "sudden-death tiebreaker" (If and when the score reached four points all, both players faced simultaneous set point and/or match point.). This type of tiebreaker had its Grand Slam debut at 1970 US Open and was employed there until 1974. Apart from being used for 5 years at US Open it was also used 1 year at Wimbledon and for a while on the Virginia Slims circuit and in American Colleges.
The line dividing the service line in two is called the center line or center service line. The boxes this center line creates are called the service boxes; depending on a player's position, he or she will have to hit the ball into one of these when serving.[53] A ball is out only if none of it has hit the line or the area inside the lines upon its first bounce. All lines are required to be between 1 and 2 inches (25 and 51 mm) in width, with the exception of the baseline which can be up to 4 inches (100 mm) wide (although in practice it is often created the same width as the rest).[52]

A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the center. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.

The track opens with Lorde questioning "Don't you think that is boring how people talk?" with her, in the words of Lester, "sweet, sultry and sour" voice, which suggests "a frictional relationship with the high life".[37] This line also summarises Pure Heroine's central theme of Lorde's observations and critiques of mainstream culture.[39][40] Lorde repeats the tongue-in-cheek word "Yeah" after each verse.[41] The refrain contains the lyrics "Baby be the class clown / I'll be the beauty queen in tears", which feature "class clown" and "beauty queen" stereotypes of high school students[25][42] and express underlying sorrow behind superficial beauty.[43][44] Follow-up lines "It's a new art form showing people how little we care / We're so happy even when we're smilin' out of fear" illustrate Lorde feigning disinterest when facing fame and adolescence.[25][42] In the second verse, Lorde wonders about her future music career, therefrom expecting inevitable nostalgia of her non-celebrity lifestyle, "But my head's filling up with the wicked games, up in flames / How can I fuck with the fun again, when I'm known?"[28][45][46][47] At the bridge, Lorde sings "I fall apart, with all my heart / And you can watch from your window", which HuffPost interpreted as a commentary on the breakdowns of teenage celebrities.[32]

A game consists of a sequence of points played with the same player serving, and is won by the first side to have won at least four points with a margin of two points or more over their opponent. Normally the server's score is always called first and the receiver's score second. Score calling in tennis is unusual in that (except in tie-breaks) each point has a corresponding call that is different from its point value. The current point score is announced orally before each point by the judge, or by the server if there is no judge.
Steffi Graf is considered by some to be the greatest female player. Billie Jean King said in 1999, "Steffi is definitely the greatest women's tennis player of all time."[123] Martina Navratilova has included Graf on her list of great players.[123] In December 1999, Graf was named the greatest female tennis player of the 20th century by a panel of experts assembled by the Associated Press.[124] Tennis writer Steve Flink, in his book The Greatest Tennis Matches of the Twentieth Century, named her as the best female player of the 20th century, directly followed by Martina Navratilova.[125]
This is a pretty serious level of tennis. The NCAA colleges have a very high skill ceiling for their tennis programs. They are looking for players who preferably have an ITF ranking and pretty proficient at their craft. To achieve this level of tennis you have to get your child in training from a very young age, like at 7-9 years old. They should have a dedicated plan for what they are going to do in their formative years because you have to maintain a balance of study and great tennis to get accepted into NCAA colleges on a sports scholarship. If your kid shows the talent then they can learn all the fundamentals in less than two years and they can keep practicing to perfect them.
The best marks for this racquet were awarded to the services on which the racquet split the air with power on contact to allow them to reach their targets. However, the EZONE 98 (305 g) will not suit everyone. Some players will enjoy the more damped feel of the DR, while others will prefer the firmer, more powerful response offered by this new version.
Badminton rackets are light, with top quality rackets weighing between about 70 and 95  grams (with guts ). Modern rackets are composed of carbon fiber composite (graphite reinforced plastic), which may be augmented by a variety of materials. Carbon fiber has an excellent strength to weight ratio, is stiff, and gives excellent kinetic energy transfer. Before the adoption of carbon fiber composite, rackets were made of wood to their excessive weight and cost.
A game point occurs in tennis whenever the player who is in the lead in the game needs only one more point to win the game. The terminology is extended to sets (set point), matches (match point), and even championships (championship point). For example, if the player who is serving has a score of 40-love, the player has a triple game point (triple set point, etc.) as the player has three consecutive chances to win the game. Game points, set points, and match points are not part of official scoring and are not announced by the chair umpire in tournament play.
Outside Australasia, the single achieved modest commercial success. It peaked at number 78 on the Canadian Hot 100 and remained for five weeks on the chart.[61] The track earned platinum certification from Music Canada, which denotes shipments of 80,000 copies in the country.[62] The single had the similar position on the UK Singles Chart and was certified silver by the British Phonographic Industry for track-equivalent sales of 200,000 units, based on sales and streams.[63][64] It also entered the top 100 of the German Singles Chart, where it reached number 83.[65] Despite not entering the record chart of Norway, the song was certified platinum by IFPI Norway for exceeding sales of 10,000 units in the country.[66] In the US, "Tennis Court" debuted at number 71, which was also its highest placement, on the Billboard Hot 100 chart dated 19 October 2013.[67] The single spent 18 weeks on the chart and had sold 355,000 copies in the US by April 2014.[68][18] It also reached number nine on the Hot Rock Songs, a Billboard auxiliary chart.[69]
The track at Astoria Park is currently closed for reconstruction as part of our Anchor Parks initiative to improve the quality of major parks across the city. While the track is under construction, we encourage you to join the New York Road Runners’ free weekly NYRR Open Run, which meets for walks and runs on Saturdays at 9:00 a.m. north of the parking lot, by the pool. You can also look for NYRR Mile Markers to track your distance along a measured course in the park. Please visit our Capital Projects Tracker for the latest on our construction progress.
Between 1859 and 1865 Harry Gem, a solicitor and his friend Augurio Perera developed a game that combined elements of racquets and the Basque ball game pelota, which they played on Perera's croquet lawn in Birmingham, England, United Kingdom.[10][11] In 1872, along with two local doctors, they founded the world's first tennis club on Avenue Road, Leamington Spa.[12] This is where "lawn tennis" is used as a name of activity by a club for the first time. After Leamington, the second club to take up the game of lawn tennis appears to have been the Edgbaston Archery and Croquet Society, also in Birmingham.
