Another benefit of post-tensioning is that contractors can build larger slabs using thinner concrete sections, and they don't have to install control joints which can interfere with play. "In order to build a reinforced concrete court that has the same structural capabilities as a post-tensioned court, we would have to install so much steel and concrete that the reinforced court would actually cost more," says Kolkmann. "Also, a reinforced court needs control joints, usually at a spacing of 10 to 15 feet, including in the playing area. Eventually these joints may widen, as well as any cracks that appear."
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". Modern research however, holds this thesis in a highly questionable light. 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".
A tie-break set is played with the same rules as the advantage set, except that when the score is tied at 6–6, a tie-break game (or tiebreaker) is played. Typically, the tie-break game continues until one side has won seven points with a margin of two or more points. However, many tie-break games are played with different tiebreak point requirements, such as 8 or 10 points. Often, a 7-point tie-breaker is played when the set score is tied at 6–6 to determine who wins the set. If the tiebreak score gets to 6-6, then whichever player to win the best of two points wins the set. 
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." Martina Navratilova has included Graf on her list of great players. 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. 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.
Ball boys and girls may be employed to retrieve balls, pass them to the players, and hand players their towels. They have no adjudicative role. In rare events (e.g., if they are hurt or if they have caused a hindrance), the umpire may ask them for a statement of what actually happened. The umpire may consider their statements when making a decision. In some leagues, especially junior leagues, players make their own calls, trusting each other to be honest. This is the case for many school and university level matches. The referee or referee's assistant, however, can be called on court at a player's request, and the referee or assistant may change a player's call. In unofficiated matches, a ball is out only if the player entitled to make the call is sure that the ball is out.

Standard squash rackets are governed by the rules of the game. Traditionally they were made of laminated timber (typically Ash), with a small strung area using natural gut strings. After a rule change in the mid-1980s, they are now almost always made of composite materials such as carbon fiber or metals (graphite, Kevlar, titanium, and/or boron) with synthetic strings. Modern rackets are 70 cm long, with a maximum strung area of 500 square centimetres (approximately 75 square inches) and a mass between 90 and 200 grams (4–7 ounces).
Your swing style is another important factor to consider when shopping for tennis racquets. If you have a fast and long swing, you are likely able to provide all the power you need and may want to consider a racquet with a mid or mid-plus head, which can help you control your shot. If you have a shorter and slower swing, an oversized racquet head may be a better choice as it can increase the power of your shot.
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. 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). The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (0.91 m) high in the center. 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.
Leading juniors are allowed to participate for their nation in the Junior Fed Cup and Davis Cup competitions. To succeed in tennis often means having to begin playing at a young age. To facilitate and nurture a junior's growth in tennis, almost all tennis playing nations have developed a junior development system. Juniors develop their play through a range of tournaments on all surfaces, accommodating all different standards of play. Talented juniors may also receive sponsorships from governing bodies or private institutions.
Balls wear out quickly in serious play and, therefore, in ATP and WTA tournaments, they are changed after every nine games with the first change occurring after only seven games, because the first set of balls is also used for the pre-match warm-up. As a courtesy to the receiver, the server will often signal to the receiver before the first serve of the game in which new balls are used as a reminder that they are using new balls. However, in ITF tournaments like Fed Cup, the balls are changed in a 9–11 style. Continuity of the balls' condition is considered part of the game, so if a re-warm-up is required after an extended break in play (usually due to rain), then the re-warm-up is done using a separate set of balls, and use of the match balls is resumed only when play resumes.
But it’s not all downside, emotionally, a reckoning with limits and failure, that I’m feeling when I’m playing with Kirill. I have improved, and am proud of that. Being able to spend a couple of hours each week playing with a gifted athlete — and a natural teacher — is gratifying in and of itself. There is also, for instance, the patience I feel at times — patience, finally, as I near 60 — when Kirill and I are rallying for 8 or 9 or 12 or 15 shots. He has a way of sensing when I have found a rhythm (he has told me as much) and he will start hitting with more pace, and I will feed off it, and then he will alter his shots — topspin, flat, slice — to make me take the ball in different strike zones, high to low. And as I at once concentrate but do not overthink; move quickly but without restless tension; and am neither consumed with winning the rally nor anxious about losing it, I am as serene in a moment as I have ever been or am likely to be.
A set consists of a sequence of games played with service alternating between games, ending when the count of games won meets certain criteria. Typically, a player wins a set by winning at least six games and at least two games more than the opponent. If one player has won six games and the opponent five, an additional game is played. If the leading player wins that game, the player wins the set 7–5. If the trailing player wins the game (tying the set 6–6) a tie-break is played. A tie-break, played under a separate set of rules, allows one player to win one more game and thus the set, to give a final set score of 7–6. A "love" set means that the loser of the set won zero games, colloquially termed a 'jam donut' in the USA. In tournament play, the chair umpire announces the winner of the set and the overall score. The final score in sets is always read with the winning player's score first, e.g. "6–2, 4–6, 6–0, 7–5".
SportMaster tennis court surfaces are technically advanced, 100% acrylic sports surfaces. Many people refer to tennis court surfaces as “tennis court paint”, but SportMaster systems are designed to provide consistent speed of play, texture, and vibrant color to any indoor or outdoor facility. SportMaster tennis court surfaces are formulated to resist fading and withstand a variety of weather conditions from ice and snow to intense heat and ultra-violet rays.
This is a great question because it is so important to playing the game well. A grip size that is too small will cause your hand to slip on your racquet a little and a grip size that is too big will restrict your wrist movement and make it hard to adjust your grip as you play.To measure your grip you need to take out a measuring tape. Place your fingers on your hand extended out and together and then turn your palm up. With the measuring tape take a measurement from the very end of your ring finger down to the bottom crease in your palm (usually adjacent to where your thumb attaches to your palm). That will be the size grip you need to look for. It usually will fall between 4 inches and 4 ¾ inches on most people.Keep in mind that you may want to add a layer of grip tape to your new racquet like many people do. If you are one of those people then it is best to get a grip size that is one size smaller than what you measured your hand to be. This will allow for the extra grip tape without making the grip too big for your hand.
Premier events for women form the most prestigious level of events on the Women's Tennis Association Tour after the Grand Slam tournaments. These events offer the largest rewards in terms of points and prize money. Within the Premier category are Premier Mandatory, Premier 5, and Premier tournaments. The Premier events were introduced in 2009 replacing the previous Tier I and II tournament categories. Currently four tournaments are Premier Mandatory, five tournaments are Premier 5, and twelve tournaments are Premier. The first tiering system in women's tennis was introduced in 1988. At the time of its creation, only two tournaments, the Lipton International Players Championships in Florida and the German Open in Berlin, comprised the Tier I category.
Play all your practice games in sets. Tennis is played in sets--you don’t just play one game and then go home! Sets consist of at least six games. The set doesn’t end until one player wins six games and has a margin of two wins over their opponent. For example, if one player has won six games and the other has won five, they’ll have to keep playing until the winner has two more wins than the loser.
"Tennis Court" is written in the key of A minor and has a moderate tempo of 92 beats per minute. Lorde's vocal range on the song spans one octave, from G3 to G4. As with Lorde's early releases, the song features a minimalist production, employing simple and sparse instrumentation. It utilises reverbed synthesisers and an electronic pulse. "Tennis Court" combines alternative pop, art pop and downtempo genres over hip hop-influenced beats. Billboard editor Jason Lipshutz commented that "Tennis Court" conveys a darker aspect of pop music. Nick Messtite from Forbes wrote that the track was reminiscent of The Postal Service's 2003 song "The District Sleeps Alone Tonight", while Siân Rowe from NME compared the song to works by Lana Del Rey. Clash's Joe Zadeh likened the electronic composition of "Tennis Court" to that of The xx's song "Together" from The Great Gatsby soundtrack (2013).
Tie-break sets are now nearly universal in all levels of play, for all sets in a match; however, the tie-break is not a compulsory element in any set, and the actual formatting of sets and tie-breaks depends on the tournament director in tournaments, and, in private matches, on the players' agreement before play begins. Tie-breaks are not used in the final set in the Australian Open for singles before 2019, the French Open for singles, Wimbledon before 2019, or the Fed Cup, nor were they used for final sets in Davis Cup play or the Olympics before 2016. The US Open now uses a tiebreak in the final set, both in singles and in doubles, and was the only major tournament to use a tiebreak in the final set for singles before 2019, but the Australian Open and French Open do use a final set tiebreak in both men's and women's doubles.

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.
The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye.
