Helater began using snowshoes. Theoriginal tennis courts played on naturalgrass. It originated in Europe in the lateeighteenth century [citation needed]and expanded at first by English-speaking countries, especially amongthe upper classes.

  • 3. Measurements of the trackMeasurements of the tennis court.Tennis is played on a rectangular court. Its exact measurements aredefined in units of the imperial system and vary depending on themode you play (single or double). For individuals is 78 feet (23.78meters) long and 27 feet (8.23 meters) wide. For doubles, the length isthe same and the width is 36 feet (10.97 meters). These limits aremarked by lines, which are considered part of the track. A mesh-shaped track network divided into two halves that correspond to theopponents. The height of the poles network is 3 feet 6 inches (1.06meters), and in the center of 3 feet (0.914 meters). On each side of thenet there are two rectangles, measuring 21 feet (6.40 meters) long and13.5 feet (4.11 meters) wide, which serve only to determine whether aserve is valid or not.
  • 4. ScoreA tennis match is composed of sets (sets in English). The first to win a certain number ofpartial wins. Each part consists of games. In each game there is a player who draws, whichalternates. In turn, the games consist of points.The first to win 4 points with a minimum difference of 2 points compared to its rival is thewinner of a game, in case none of the two players or teams have a two to reach four pointswins the game the first to achieve a difference of 2 points. The account is quite particularpoints: when a player wins his first point, the score is 15, when you win 2 points, 30, andwhen you win 3 points, 40. For example, if the server of that game has won 3 points and 1point receiver, the score is 40-15. Always named first punch punctuation. When bothplayers are tied at 40 is said to be deuce or "equal". The first player or team to win a pointafter deuce achieved an advantage, and if he wins the next point wins the game, otherwiseit is back on deuce until there is the difference of two points.The player takes the part is getting to six games with a difference of two. In case a playerreaches 6 games, but unlike 1 (6-5) will be followed until one gets the appropriatedifference. If the tournament regulations set a limit game, have to play a special gamecalled tie-break or "sudden death", in which the outcome is decided by correlative points(one-zero-two-zero-three-zero, etc..), until someone gets reach 7 points, with difference of2. If you get to 7 points without difference of 2 (eg 7-6), will have to wait for one of the twoplayers get a difference of 2 points, which is the that gets the win in the tie-break and thepartial 7-6. The player who starts taking on a tie-break only has a kick turn (with first andsecond serve from the right side) and from there, will alternate two shifts per player pull upthe completion.
  • 5. TechniqueTennis is a sport that requires players to master techniques such as: strokes, grips, effects, bodypositions and movements, as well as physical stamina needed to endure long rallies.KnockingDuring the game, using many types of shots, each with their techniques, the hits are: theserve, the right, the back, the globe, with it, the left and the top.ServeThe serve is the most important hit of tennis, as this starts the point, and its correct applicationcan allow the person taking be in an advantageous position upon return or achieve one ace orace (earned point without impact the opponent the ball), or the impact of the adversary after theball does not come to pass the network or it will go beyond the limits of the bands (in which caseit is called ace, but off spot). By having good serve, the player learns to finish better shocksmade ​​without the ball touches the ground and make it hard for the opponent can score a pointafter you make a cut.The second serve is usually done seeking safer outcome. This often made topspin serves, cut orkick to cause greater difficulty rival, since those usually dangerous serves to change the directionof the ball or the speed after the bounce. One of the changes as does each serve is that thecut, try to make the ball run across the strings from side to side of the upright bike, and equalstopspin but horizontally.Among the best punches of the Open Era are called Croats Goran Ivanicevic and IvoKarlovic, Americans Pete Sampras, Andy Ruddick and John Isner, Roger Federer and DutchmanRichard Krajicek.
  • 6. DrivePreparation for the drive (left-handed).The drive or right is the basic beat. Is to hit theball after the bounce, directly, on the same side ofthe business arm of the player. For most players isthe ultimate weapon to win a point and the mostcontrol.For proper drive, it should be shaped to the ball,in the case of a right-handed, the stroke begins onthe right side of the body, continuing therethrough to hit the ball and ending at the left sideof the body.The impact should be in the area betweenshoulder and hip, and the movement is frombottom to top. Once the ball hits the racket, thetennis player puts his arm straight before closingthe blow. At the moment the ball comes up, theplayer makes the decision to give a powerful blowor cross somewhere.It is the easiest stroke to learn, being also the mostnatural.
  • 7. SetbackOne-handed backhand.The reverse is the blow to the side opposite the drive. Despite being a naturalmechanical stroke is usually one of the hardest to master when you start in tennis.It is very important to position the body, which should be placed in profile, usedas a technique for this, lower the shoulder to point towards the network, while theright arm for right-handed and left on the left-handed passes without beingdeflected by under the chin, to settle back before returning to hit the ball, alwaysin front of the body. It is important, as the drive, that the body weight is movedback and forth at the time of ball impactDecades ago, the backhand was taught to hit it taking the racquet with one hand(a great exponents of this technique were Ivan Lendl, Gustavo Kuerten, KenRosewall, Guillermo Vilas, Gaston Gaudio, Stefan Edberg, Pete Sampras and BorisBecker. At present they are Stanislas Wawrinka, Roger Federer, RichardGasquet, Fernando Gonzalez. Nowadays two-handed backhand is gaining moreand more ground, players like David Nalbandian, Rafael Nadal, Juan Martin DelPotro, Novak Djokovic and already retired Marcelo Rios and Andre Agassi makeuse of this coup. would be worth remembering Jimmy Connors and Bjorn Borgwhose strokes inspired two-handed backhand which is currently popularizingthis form of scrimmage.
  • 8. ForehandThe volley or air blow is the stroke that is performed before the ball bounce on theground. It is usually performed near the net to define a point. Because the player closerto the opponent, is a blow that needs to be done with great speed and reflex. The racketmust be at all times in front and high. The coup was carried carrying on foot opposite theside where the ball will hit simultaneously with the shaping of the body, so that theracquet can do a quick backward movement to hit the ball forward and from top tobottom, using the force that brings the ball itself, if possible without using extra energywithout bending the wrist. The blow that is used to reach the network in a play calledapproachLetThe left or drop shot (English drop, drop) is a hit in which power is subtracted from theball with the intention of dropping as close to the network, the other side. It is usuallyperformed to drive, but you can also do reverse. Beat The preparation is similar to thepreparation of the drive (or reverse), and must be made at the last moment, to surprisethe opponent, waiting for a shot at the bottom. Upon impact, instead of realizing thelarge swing, the racquet must fall perpendicular to the ball with a flick of the wrist, toproduce that will trickle down to the ball and have a good network.It is generally used when the opponent player is far behind the strap of the back of thecourt, and not a knock that should be used with great regularity, since the aim is tosurprise the opponent.
  • 9. ContradejadaThe counter is usually left to a left adequate response, which the player comes shortly before thesecond bounce. As the ball is usually very low and close to the net, it is not possible to use a powerfulblow, thus, the player only has the option to perform a soft knock on the merits, i.e., a new leftresponse , this time made from near the net. Contradejada is one word, not two.Attempt or smashThe smash or closing is a blow that is done on the head with a kick like motion. Usually you can hitwith great force relatively safely and is often a defining shot. Most are performed near the net or inthe middle of the track before the bounce of the ball. It is often the answer to a balloon made by theopponent was not high enough. It can also be done from the baseline after the chop, although lessdefining. It is a high punch, made from the top down, before the ball bounces, or after it does, butonly if this takes a parable more vertical than horizontal. To be effective, it is essential to be verypowerful and not given an opportunity to answer the contrary, since it is always a hit in definition. Itis done when the ball is very high, up to the outstretched arm of the player.The coup is prepared outlining the body, bringing the racket back and placing it behind hishead, while his free hand pointing to the top, towards the ball. At the moment of impact, the rearfoot goes forward, while leaving behind the racket body in a movement similar to the serve. Uponball impact, the wrist should be flexed downward, ending the coup similarly to serve. The ball mustbounce before the return instead. Main article: Big Willy. player Guillermo Vilas.
  • 10. Ways to hit the ballIn different strokes the ball may be impactedin different ways, thereby giving impact andimpede the return paths. They are obtainedwith different handles and ball impactshapes.Each of the strokes, with their respectivepaths as the effect applied on the ball andthe respective types of boat against thesurface are explained below.
  • 11. Hit topspinBall dragged from the bottom up, to produce topspin.The topspin shot or top spin (literally in English "effect from above") is a type ofimpact on the ball, by which it is "brushed" from below, "wrapping" with a twist ofthe wrist, imposing an effect forward rotation, which makes the ball bounce when,from flying upward and forward, the opposing player sending back. Notably topspinalso be produced with a rapid acceleration of the elbow, allowing us to print morepower to the ball. This shot requires fast movements, especially of the legs, as itrequires hitting the ball in front of the player, however, if played wrist, can hit frommore points, as it is a safer stroke, although less potent .
