Tennis originated almost a millennium ago. In 1873, Major Walter Clopton Wingfield designed and patented a game which he called sphairistike. This name was later transformed into "lawn tennis". The club founded by Major Harry Gem and Augurio Perera in the Spa region is known as the first tennis club in history. It did not take long for lawn tennis to become popular since it was one of the rare sports which could be played by both sexes. People played tennis not only on grass but also on other surfaces and indoors. Although many countries dropped the word "lawn" during 1970s and began to call the game simply "tennis", the International Tennis Federation (ITF) kept the name until 1977. The national governing body of tennis in Great Britain still calls itself the Lawn Tennis Association (LTF). Spread across the USA and Australia during the 20th century, tennis was introduced to Turkey by the British.
Tennis is one of those rare sports which can be played indoors and outdoors by both sexes, the old and disabled. Each player uses a racket and tries to send a tennis ball over a net into the opponent's court in such a way that his or her opponent cannot return it. Who to serve first is decided with a toss of a coin or spin of a racket. The game starts when the player who has won the right to serve goes to the baseline, tosses the ball into the air and hits it into the diagonally opposite service box without touching the net. A set consists of a sequence of games. Except in special tournaments, men play five-set matches and women play three-set matches.
Tennis is a good fat burner. It energizes the players and makes them more agile. Having to watch the ball all the time keeps players on the move. It strengthens leg muscles and bones. It not only encourages people to get into a habit of regular exercise but also improves their work discipline.
