During informal play of tennis, especially at tennis clubs in the U.S. (also in other English speaking countries), score announcements are frequently shortened with the use of abbreviations. For example, a score 15 is replaced with "five", or in some cases "fif". "Love" is often substituted to indicate "zero". Similarly, the scores of 30 and 40 may sometimes be spoken as "three" or "four" respectively. A score of 15-all may sometimes be announced as "fives." To further confuse score announcements, a score of 30-all (30–30) may often be called "deuce", and the following point referred to as "ad in" or "ad out" (or "my ad" or "your ad"), depending on which player (or team) won the point. The logic for this is that a 30-all score is effectively the same as deuce (40–40).[34]
Another alternative set format are so called "short sets" where the first to four games to win by two games. In this format a tie-break is played at four games all. The ITF experimented with this format in low level Davis Cup matches, but the experiment was not continued. Nevertheless, this alternative remains as an acceptable alternative in the ITF rules of Tennis.[32]
Muscle strain is one of the most common injuries in tennis.[79] When an isolated large-energy appears during the muscle contraction and at the same time body weight apply huge amount of pressure to the lengthened muscle, muscle strain can occur.[80] Inflammation and bleeding are triggered when muscle strain occurs, which can result in redness, pain and swelling.[80] Overuse is also common in tennis players of all levels. Muscle, cartilage, nerves, bursae, ligaments and tendons may be damaged from overuse. The repetitive use of a particular muscle without time for repair and recovery is the most common cause of injury.[80]
Why is your tennis racquet so important? It gives you an edge when playing if you use a tennis racquet that caters to your skillset. That is why it is so important to know what to look for when you are shopping for a new one. Such things as tennis racquet size should not be overlooked. There simply is no doubt that with the right tennis racquet in your hands it can really help you elevate your game to a much higher level.
Kolkmann says that asphalt courts can also develop low areas over time due to settling of the soil or base under the asphalt surface. "With a post-tensioned slab, this area can be bridged and no settling will occur. In addition, concrete courts can often be installed on unstable soils where it would be cost-prohibitive to do extensive excavating and base work to support an asphalt court," he says.
Racket is the standard spelling of the word. Racquet is an alternative spelling[2][3] used more commonly in certain sports (squash, racquetball, badminton, tennis) and less commonly in others. While some writers, especially those outside North America, prefer the French-influenced racquet, racket is the predominant spelling by a large margin.[1] Similarly, while some believe that racket came about as a misspelling of racquet, racket is in fact the older spelling: it has been in use since the 16th century, with racquet only showing up later in the 19th century as a variant of racket.[1]

Pitchfork writer Lindsay Zoladz applauded the song's narrative for "exposing irony and even hypocrisy without coming off as preachy or moralistic".[50] On behalf of Consequence of Sound, Jon Hadusek selected the song as an "essential" track of Pure Heroine regarding its narrative lyrics portraying Lorde's songwriting that was "beyond her years".[46] Time Out editor Nick Levine similarly lauded Lorde's "compelling" songwriting ability despite her young age at the time and praised the song's composition as "glorious".[45] AllMusic's Stephen Thomas Erlewine and The Independent's Andy Gill also picked "Tennis Court" as a standout track of Pure Heroine,[51][52] while John Murphy from musicOMH complimented the track as "impossible not to sing along to".[53] In a less enthusiastic review, Evan Sawdey of PopMatters considered the song a "drawback" that does not "[suit] her well".[54]
Head size plays a very key role in a racket's performance characteristics. A larger head size very generally means more power and a larger "sweet spot". This is an area in the string bed that is partially more forgiving on off-center hits and which produces more ball-reflective power from string deformation, known as the trampoline effect. However, large head sizes can increase twisting, which makes off-center hits more difficult to control and can reduce a player's overall power production due to the playing compensating for the extra inherent power, typically with stiffer strings to reduce the increased string deformation of large heads. A smaller head size generally offers more control for many shots, particularly the service and groundstrokes aimed near the lines, but can lead to more shanks (wild misses, from hitting the frame or missing the sweet spot). This drawback is most common for professional players using single-handed topspin backhands, as well as for recreational and aged players at net. Shanking due to small racket head size is typically exacerbated by racket weight, which slows the reaction time, as well as, to a lesser degree, the racket's balance point. In professional tennis, currently-used racket head sizes vary between 95–115 square inches (610–740 cm2), with most players adopting one from 98–108 square inches (630–700 cm2). Rackets with smaller and larger head sizes, 85 and 120–137 square inches (550 and 770–880 cm2), are still produced but are not used by professionals currently. A very small number of professionals, such as Monica Seles, used 125 square inches (810 cm2) rackets during some point in their careers. Rackets with smaller heads than 85 square inches (550 cm2) have not been in production since the 1980s and rackets with larger head sizes than 137 square inches (880 cm2) are not currently legal for the sport, even though only elderly players typically choose to use rackets beyond 115 square inches (740 cm2) and it is nearly unheard-of for a serious player who is not elderly to choose a racket over 125 square inches (810 cm2). The WEED company, founded by Tad Weed, specializes in producing very large rackets, primarily for the elderly market. Rackets that are moderately higher in power production, moderately lower in weight, moderately larger in size, and which typically possess a slightly head-heavy balance are often called "tweener rackets."[11] Rackets that have the smallest heads in current use, the highest weights in current use, and headlight or even balance are referred to as "players' rackets". Oversize rackets, typically 110 square inches (710 cm2) in size, were once pejoratively referred to as "granny sticks" but resistance to them being seen as illegitimate rackets for younger players decreased dramatically with the successful use of these rackets by a small number professionals such as Andre Agassi and Pam Shriver. Originally, even midsize frames (85 square inches (550 cm2)) were considered jumbo, and some top players, such as Martina Navratilova and Rod Laver said they should be banned for making the sport too easy. Later, these same professionals, including John McEnroe, signed a letter supporting a switch back to wood frames, or a limitation to the original standard size of approximately 65 square inches (420 cm2). Perhaps the last professional to use a standard-size racket in professional tennis was Aaron Krickstein, known for the strongly-contested match against Connors at the 1991 US Open. He used a Wilson Ultra-II standard-size graphite racket also used in the 1980s by the hard-hitting teen Andrea Jaeger. The first oversize, the fiberglass Bentley Fortissimo from Germany, was praised by racket designers but was considered too large to be taken seriously by the small number of players who were exposed to it.
Both color coatings and cushioned surfacing systems come in an array of colors, allowing you to branch out from the traditional green court surface and use nearly any color or combination of colors you choose on your backyard tennis court. While there is no "regulation" color scheme for tennis courts, some colors work better under certain conditions.
I spent a year having lessons with one pro, then another. It wasn’t working out. I realized I wanted not just instruction but a relationship — someone I was not only going to learn from but also talk with, or talk at, anyway, about all this stuff that might have been about tennis but was probably about a lot of other things. I was about to give up.

Moving, always moving, and all the time thinking and checking off: Maintain the continental grip, the base knuckle of the index finger of my left hand resting on the bevel one notch counterclockwise from the racket handle’s high noon. (Check.) Keep the racket in front and the racket head up. (Check.) Knees slightly bent. (Check.) Turn sideways quickly, and punch with your shoulder, don’t swing; and tighten your grip at the moment the ball is about to hit the strings.

The first year with Kirill was brutal. The prescribed continental grip felt awkward when I first began to serve. I thought I was turning my shoulder, properly, to prepare to hit a backhand, but wasn’t. I thought I was, properly, following through on my forehand, and wasn’t. It was the strangest thing. I had no sense at times of what my body was doing. And that, to some extent — a frustrating and at times embarrassing extent — continues. And it continues despite the incessant midplay appeals from Kirill to correct this, correct that. One of the things about having a coach is that no one has watched how I move more intently since I was a toddler.
Experienced players strive to master the conventional overhand serve to maximize its power and placement. The server may employ different types of serve including flat serve, topspin serve, slice serve, and kick (American twist) serve. A reverse type of spin serve is hit in a manner that spins the ball opposite the natural spin of the server, the spin direction depending upon right- or left-handedness. If the ball is spinning counterclockwise, it will curve right from the hitter's point of view and curve left if spinning clockwise.[75]
In 1926, promoter C. C. Pyle established the first professional tennis tour with a group of American and French tennis players playing exhibition matches to paying audiences.[26][37] The most notable of these early professionals were the American Vinnie Richards and the Frenchwoman Suzanne Lenglen.[26][38] Once a player turned pro he or she was no longer permitted to compete in the major (amateur) tournaments.[26]
