Post-tensioned concrete is reinforced with a grid of high-strength sheathed steel tendons, or cables. While the concrete is curing, the cables are tensioned in both directions and held permanently under stress by anchoring them in a perimeter beam. This squeezing action keeps the concrete in compression, improving its tensile (or bending) strength. The more the concrete is squeezed together, the less likely it is that shrinkage cracks will develop or open. (See a more complete description of post-tensioning from the Post-Tensioning Institute.)

Sometimes a company will include some extras in with the tennis racquet and these are always nice to have. So if you can get a nice cover to help protect your racquet when not using it or a can of decent tennis balls this is never a bad thing. Don’t make it a point of emphasis in your tennis racquet buying decision but these things are a nice bonus if you can get them.
3. They often take only private lessons and play points when they play on their own – which means that they do not have enough repetitions in situations without pressure where they could automate their technique. In other words, they don’t practice enough – they only get more information in private lessons and do not groove the strokes in practice.
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.

Net Worth: The Radical Pro was what was sitting in Andy Murray’s hand when he rocked Wimbeldon, so it damn sure deserves a place in your bag. At 11.5oz it is a nice mid-weight racket, though thanks to the way its balanced it moves like a much lighter piece of equipment. On power swings you are going to notice some sluggishness, but barely enough to make a difference. This is definitely a control players racket with its 98 square-inch head which allows for decent serve speed but sluggers won’t get the crushing power they desire. For smooth operation when making a net play, it works wonders and allows for sniper-level ball placement. For pure power it’s not a winner. [Purchase: $190]

Tournaments are often organized by gender and number of players. Common tournament configurations include men's singles, women's singles, and doubles, where two players play on each side of the net. Tournaments may be organized for specific age groups, with upper age limits for youth and lower age limits for senior players. Example of this include the Orange Bowl and Les Petits As junior tournaments. There are also tournaments for players with disabilities, such as wheelchair tennis and deaf tennis.[81] In the four Grand Slam tournaments, the singles draws are limited to 128 players for each gender.
During the 19th century the Royal Tennis Court played a variety of different roles. It served as a theatre storeroom, a workshop and storage space, and a studio for the painters Antoine-Jean Gros and then Horace Vernet. It was listed as a national monument in 1848, then became a games room again under the Second Empire. Approaching the centenary of the oath, under the Third Republic, architect Edmond Guillaume was invited to restore it and convert it into a museum of the French Revolution. The architect used original engravings to reconstitute the spirit of the room, which had been modified and had deteriorated over the course of the century. The museum housed the statue of Bailly, busts of the most important signatories of the oath, and a monumental canvas by Luc-Olivier Merson, based on Jacques-Louis David's preparatory drawing. The museum was inaugurated on 20 June 1883 in the presence of Jules Ferry.

It happened again the other afternoon. The thermometer on the side of the tennis house had reached 91 degrees, and there were just a few members playing on the club’s main upper courts. Down on the practice courts, where we were, there may have been a light breeze coming off the nearby westernmost reaches of Long Island Sound, but I couldn’t feel it, and the gray-green Har-Tru clay my sneakers grabbed for was powdery and uncooperative. Kirill was across the net from me, at the T between the service boxes, a wire cart at his side filled with hundreds of tennis balls. I was at the T on my side, already a little winded, trying not to fail.


It was a thought — being a tennis player — that first came to me five years ago when I was months from my 55th birthday. It wasn’t that I imagined I was going to become an athlete. I am a tennis fan, and I turn on ESPN and attend the United States Open each year with the understanding that the men and women I love to watch are, as they were not when I was a boy, a breed apart: selection for size and intense training and competition from early childhood is increasingly creating a sort of warrior class in sports. I wanted to become a very good recreational player. Someday.
In standard play, scoring beyond a "deuce" score, in which both players have scored three points each, requires that one player must get two points ahead in order to win the game. This type of tennis scoring is known as "advantage scoring" (or "ads"). The side which wins the next point after deuce is said to have the advantage. If they lose the next point, the score is again deuce, since the score is tied. If the side with the advantage wins the next point, that side has won the game, since they have a lead of two points. When the server is the player with the advantage, the score may be called as "advantage in". When the server's opponent has the advantage, the score may be called as "advantage out". These phrases are sometimes shortened to "ad in" or "van in" (or "my ad") and "ad out" (or "your ad"). Alternatively, the players' names are used: in professional tournaments the umpire announces the score in this format (e.g. "advantage Nadal" or "advantage Williams").
Very simply, find yourself a certified and reputable teaching professional (“pro”) and take a handful or dozen lessons over the course of a few weeks to jump-start the learning process and help you retain and apply the instructors teachings. Don’t be surprised or alarmed if the pro has you doing some things that feel awkward, or asks you to change the way you’ve been doing things before. He or she may have you doing certain exercises or “drills” that are designed to develop specific skills that, to you, may seem impractical or odd, but which actually work. Be patient, be alert, be attentive, Listen and apply as much as you can. Finally, come prepared to each lesson by having practiced at least once or twice since the previous lesson, and bring water and a towel, sunglasses, sunscreen and a cap to prevent sunburn and heat exhaustion.
Here is an oldie but goody from the very reputable tennis racquet manufacturer prince. They were among the first tennis racquet companies to take the technology used to build them to a whole new level. This is the type of racquet that is preferred by more traditional players that like to make the ball react because of their swing and not because of some fancy tennis racquet design.
Two hands give the player more control, while one hand can generate a slice shot, applying backspin on the ball to produce a low trajectory bounce. Reach is also limited with the two-handed shot. The player long considered to have had the best backhand of all time, Don Budge, had a powerful one-handed stroke in the 1930s and 1940s that imparted topspin onto the ball. Ken Rosewall, another player noted for his one-handed backhand, used a very accurate slice backhand through the 1950s and 1960s. A small number of players, notably Monica Seles, use two hands on both the backhand and forehand sides.
Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
