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 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.

The ITF's Play and Stay campaign promotes playing on smaller courts with slower red, orange and green balls for younger children. This gives children more time and control so they can serve, rally, and score from the first lesson on courts that are sized to fit their bodies. The ITF has mandated that official competition for children under 10 years of age should be played on "Orange" courts 18 m (59 ft) long by 6.4 m (21 ft) wide. Competition for children under 8 years is played on "Red" courts that are 11 m (36 ft) long and 5.5 m (18 ft) wide. The net is always 0.8 m high in the center.[4]
There is nothing that says you cannot look good when you play the game of tennis and that includes having a stylish tennis racquet that accentuates your attire. It is probably not something that you want to be a major factor in your purchasing decision but if you have narrowed your choices down to 2 or 3 similar racquets it can be used as the deciding factor.

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 serve (or, more formally, a "service") in tennis is a shot to start a point. The serve is initiated by tossing the ball into the air and hitting it (usually near the apex of its trajectory) into the diagonally opposite service box without touching the net. The serve may be hit under- or overhand although underhand serving remains a rarity.[73] If the ball hits the net on the first serve and bounces over into the correct diagonal box then it is called a "let" and the server gets two more additional serves to get it in. There can also be a let if the server serves the ball and the receiver isn't prepared.[74] If the server misses his or her first serve and gets a let on the second serve, then they get one more try to get the serve in the box.
Then Kirill, to mix things up, lobbed one over my head. Move, think: I turned sideways, began running back using a crossover step, stopped, pointed up with my free right hand toward the descending ball, brought my racket back over my shoulder, contacted the ball with a wrist snap — and watched my overhead smash hook, decidedly, a long yard off the court.
If you find reading boring then you can try watching free instructional videos on the internet. The best part about these videos is that it is made by tennis pros who are passionate about teaching tennis, so you won’t find the videos hard to understand. Between reading and watching the instructional videos, you will pick up important details about tennis on your own.

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.


To promote her works to American audiences, Lorde held her first US show at Le Poisson Rouge in New York on 6 August 2013 and performed "Tennis Court" among songs from The Love Club EP.[75] She subsequently included the song on the set list for her debut concert Pure Heroine Tour, which ran from late 2013 throughout 2014 in support of her debut studio album.[76][77] On 13 November 2013, Lorde performed "Tennis Court" among five other songs from The Love Club and Pure Heroine on Live on Letterman.[78] Six days later, Lorde held her first UK concert at Soho, London, where she performed several tracks from Pure Heroine including "Tennis Court".[79] She also performed the track during the "Almost Acoustic Christmas" event on KROQ-FM radio station on 9 December.[80]

A legal service starts a rally, in which the players alternate hitting the ball across the net. A legal return consists of the player or team hitting the ball before it has bounced twice or hit any fixtures except the net, provided that it still falls in the server's court. A player or team cannot hit the ball twice in a row. The ball must travel past the net into the other players' court. A ball that hits the net during a rally is still considered a legal return as long as it crosses into the opposite side of the court. The first player or team to fail to make a legal return loses the point. The server then moves to the other side of the service line at the start of a new point.[54]
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]
