So, what exactly is tennis about? The following information will help you to understand more about tennis and hopefully your interest towards the sport. 1. History of tennis A game very similar to tennis could be dated back to 13 th century in France. Tennis comes from the French Tenez, meaning a competition. The current name tennis was introduced when the sport spread through England and the rules of modern tennis was first established in The first tournament was held in 1877 at the rural area of London, Wimbledon. The modern well known tennis games include The Grand Slam Tournaments, ATP Tour, and Team Matches of Davis Cup (Men), Fed Cup (Women). The Grand Slam Tournaments are the Australian Open, French Open, Wimbledon Championships and US Open. There are ATP tours and WTA matches for professional players. Australian Open (January on hard court) French Open (May-June on clay court) Wimbledon Championships (June-July on grass court) U.S. Open (August-September on hard court) 2. General knowledge 2.1 Code of Conduct In addition to adherence to the standardized tennis rules, the players shall follow the code of conduct formulated by official associations or matches. It aims to maintain fair and reasonable standards of conduct by players and the organizers to protect their respective rights, the rights of the public and the integrity of the Sport of Tennis. Examples of code of conduct: 1

Use best effort during the matches. Maintain high level of safety. Players breaking the code of conduct will be subject to penalty, which will be determined by the respective associations or organizers. 2.2 The 5-minute Warm-up Warm-up is not practice. A player should provide the opponent a five-minute warm-up before the match starts. If a player refuses to warm up the opponent, the player forfeits the right to a warm-up. Some players confuse warm-up and practice. Each player should make a special effort to hit shots directly to the opponent On-court coaching (Team Matches) Player could receive coaching by the Captain sitting on the court, and then only when the player changes ends at the end of a game, but not when changes ends during a tie-break game. 2.4 Hawk-Eye technology The Hawk-Eye tennis system is a ball tracking technology to have passed ITF (International Tennis Federation) testing measures. The technology is now an integral part of the ATP, WTA and ITF tennis tours. It is an electronic line calling service takes the doubt out of close line calls in matches. This technology combines from 8 to 10 ball tracking cameras, four computers and a big screen. Firstly, computers were used to separate court into different areas in unit of centimeter. Next, cameras set from different angles capture the ball track, then transform data into 3D video through computers. Lastly, ball track is show on the big screen to identify whether a ball has bounced in or out. Rule of Challenge 1. Each player have 3 challenges in each set. 2. If player succeeds in challenge, it does not count as used challenge, number of challenges remain unchanged. 3. If player fails to challenge, player lost one challenge. 4. When a set goes into tie-break, each player get an extra challenge. 5. Challenges do not accumulate into a new set. Set Players should win 6 games to win a set, and win 2 sets to win a match in tour. For example, 6:0, 6:4 (Except Men s Grand Slam) If score is 6:5, the 12 th set needs to be play to 7:5. If 6:6, then tie-break will be play In Grand Slam tournaments, the best-of-5 set format is played in men s matches while the best-of-3 set format is played in women s matches. The US Open employs the tie-break set format, meaning that if there is a 6-6 tie in each set, a tie-break game deciding the winner of the set shall be played; the other three Grand Slam tournaments (the Australian Open, the French Open and the Wimbledon) employ the advantage set format, meaning that if there is a 6-6 tie in each set, the match continues until one player wins by two games. 3.

Elite players 5.1 Top Performance Playing pattern, Leg speed and mental speed 5.2 The three fundamental elements Their eyes, which is necessary for perception, anticipation and understanding of the game, of utmost importance to read the game of the opponent more easily Their feet to move at a great speed always following the shortest trajectory of the ball between the player and the ball, to reach and take on the ball in the best way, and finally, The intelligence of the hand to materialize all the ideas of the genius that all these top-level players have. 6. Singles strategy 6.1 Baseliner i) Aggressive baseliner Tries to win the point by hitting winners from the back of the court Attacks with fast penetrating balls that the opponent cannot reach or return effectively to get them back in the point Hits the ball from side to side. Usually, he/she has at least one great groundstroke, forehand or backhand. Representatives: Andre Agassi, Andy Roddick and Maria Sharapova, etc. ii) Defensive baseliner Most of the high-level athletes tend to take a defensive strategy. They return every ball and relies on the opponent making mistakes Has consistent shots, makes few errors of his own Must have speed and agility to cover the court Representatives: Michael Chang, Lleyton Hewitt and Rafael Nadal Parera, etc. 6.2 Serve-and-volley player Has a great net game, is quick around the net and has fine touch for volleys Comes up to the net at every opportunity when serving Are always attackers and can hit many winners with varieties of volleys and drop volleys Representatives: Pete Sampras and John McEnroe, etc. 6.3 All-court player World-class athletes are trained to has a combination of skills used by all tennis styles Usually has an attacking game, mixing groundstrokes and volleys to keep the opponent guessing Is very versatile, when baseline game is not working, he/she may switch to a net game, and vice versa. Player can adjust to different opponents that play different styles easier than pure baseliners or serve-and-volley players. Representatives: Novak Djokovic, Justine Henin and Roger Federer, etc. The major reason of making few errors is that they can focus on the movement of the ball. Nadal (Defensive baseliner) Sampras (Serve-and-volley player) Federer (All-court player) 7. Doubles strategy Though strategy is important in singles, it is even much more important in doubles. Below are three basic doubles strategies: 7.1 Up-and-back strategy The most basic strategy The player at the net with offensive firepower, and a player at the baseline guard against the lob Strength: it is versatile, with both offense and defense in it Weakness: there is a large angular gap between partners, so an opposing net player can easily hit a clean winner through 8 Figure 1

9 7.2 Both-back strategy (defensive) (Figure 2 Player A and B) Both players stand side by side near the baseline It is normally seen when the opponent has a serve with a lot of pressure or the opposing team is both-up They give up the aggressive position at the net, but they may return the most forcing shots till they get a chance to hit a good lob or an offensive shot Figure2 7.3 Both-up strategy (offensive) (Figure 2 Player C and D) The ideal doubles strategy, often called Attacking Doubles Both players stand side by side near the net They must have effective serves and penetrating volleys to prevent good lobs and good overhead shots to kill poor ones 8. Tennis terminology We might sometimes hear some interesting terminology in a tennis match, for example: DROP SHOT Landing of the ball is close to the net FOLLOW THROUGH The movement after hitting the ball GROUND STROKE Hit the ball after one bounce LOVE(French LUFF) Zero (nothing) RALLY Both players hitting the ball around and round SERVE AND VOLLEY Moving towards the net right after serving SWING Movement of the racquet TOP SPIN A ball spinning upward and forward 8.
