How to play tennis table (ping pong)

Table tennis, also known as ping-pong, is a sport in which two or four players hit a lightweight ball back and forth across a table using small rackets. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce one time on their side of the table, and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage.
Table tennis is governed by the worldwide organization International Table Tennis Federation (ITTF), founded in 1926. ITTF currently includes 226 member associations.[3] The table tennis official rules are specified in the ITTF handbook.[4] Table tennis has been an Olympic sport since 1988,[5] with several event categories. From 1988 until 2004, these were men's singles, women's singles, men's doubles and women's doubles. Since 2008, a team event has been played instead of the doubles.

History



The sport originated in Victorian England, where it was played among the upper-class as an after-dinner parlour game.[1][2] It has been suggested that makeshift versions of the game were developed by British military officers in India in around 1860s or 1870s, who brought it back with them.[6] A row of books stood up along the center of the table as a net, two more books served as rackets and were used to continuously hit a golf-ball.[7][8]
The name "ping-pong" was in wide use before British manufacturer J. Jaques & Son Ltd trademarked it in 1901. The name "ping-pong" then came to describe the game played using the rather expensive Jaques's equipment, with other manufacturers calling it table tennis. A similar situation arose in the United States, where Jaques sold the rights to the "ping-pong" name to Parker Brothers. Parker Brothers then enforced its trademark for the term in the 1920s making the various associations change their names to "table tennis" instead of the more common, but trademarked, term.[9]
The next major innovation was by James W. Gibb, a British enthusiast of table tennis, who discovered novelty celluloid balls on a trip to the US in 1901 and found them to be ideal for the game. This was followed by E.C. Goode who, in 1901, invented the modern version of the racket by fixing a sheet of pimpled, or stippled, rubber to the wooden blade. Table tennis was growing in popularity by 1901 to the extent that tournaments were being organized, books being written on the subject,[7] and an unofficial world championship was held in 1902.
In 1921, the Table Tennis Association was founded, and in 1926 renamed the English Table Tennis Association.[10] The International Table Tennis Federation (ITTF) followed in 1926.[1][11] London hosted the first official World Championships in 1926. In 1933, the United States Table Tennis Association, now called USA Table Tennis, was formed.[1][12]
In the 1930s, Edgar Snow commented in Red Star Over China that the Communist forces in the Chinese Civil War had a "passion for the English game of table tennis" which he found "bizarre".[13] On the other hand, the popularity of the sport waned in 1930s Soviet Union, partly because of the promotion of team and military sports, and partly because of a theory that the game had adverse health effects.[14]
In the 1950s, paddles that used a rubber sheet combined with an underlying sponge layer changed the game dramatically,[1] introducing greater spin and speed.[15] These were introduced to Britain by sports goods manufacturer S.W. Hancock Ltd. The use of speed glue increased the spin and speed even further, resulting in changes to the equipment to "slow the game down". Table tennis was introduced as an Olympic sport at the Olympics in 1988.[16]

How to Do Throw In (football)

Throwing in is simple but very important in soccer: throw-in can provide an opportunity to hold possession of the ball, counterattack, or even lose possession of the ball. Therefore, throwing in is one of the important skills in soccer. In fact, many players ignore the throw-in skills so that they throw away the opportunities. However, don't worry because with the help of this article and lots of practice, you can use throw-in like a professional player.

Gambar berjudul Do a Throw in Soccer Step 1
1) Take the ball with both hands. You should hold the ball right to the right and left. If the soccer ball is a clock, your right hand is at 3 o'clock and your left hand is at 9 o'clock. You can move it slightly inward so that your thumb almost touches the back of the ball. This helps you get more leverage when throwing.
Inward throws only occur when the entire ball passes through one side of the field. Throwing in is done at the point where the ball leaves the field. [1]


2 Aim facing the field with the tips of your toes at the edge of the field line. Both feet must be behind the field line and touch the ground so that throw-in is considered valid. Open both legs and point your fingertips to the field, and arrange your body so that you get comfortable horses. If you want to try throwing while running, stand a few meters behind the line so you can run without crossing the field line. Some players choose to close their legs, and some of them move one foot forward.
Remember, your feet should not cross the field line when throwing the ball in. When passing, the throw becomes invalid and possession of the ball will move to the opposing team. [2]











































3Arch your back. Many players who try to throw only use their hands, but some of the power of the throw must come from the shoulders and back, and the momentum from the running start. Think of your body like a slingshot drawn; both feet stand firmly on the ground, but the spine becomes like a spring. Do it just before you throw the ball.
For now, practice arching as comfortably as possible. Try to get the right attitude first before practicing throwing a ball. A little curvature should be enough for now.











































Start from the back of the head, bring the ball up and over the head. In order for the throw to be valid, the ball must "start from behind and over the head." [3] Referees may allow quick throws, but you should at least start with a ball above your head.
You will be given a violation if you start the throw from the forehead or more in the future. Usually this happens on a quick throw.












































Release the ball forward with a wrist flap. Swing your arms up and forward so that the ball moves just above your head. At the same time, resilient the arched back is like a spring, and if you throw a run, drag your back toe on the ground. Align your arms completely and release the ball so you don't just throw the ball to the ground.
The location of the ball release point depends on the desired throw distance. For far throws, release the ball as it passes through the head. For short throws, hold the ball until it is past the forehead.
You cannot twist the ball with one hand. The ball must leave both hands together, even though the referee will usually tolerate it provided you do not twist the ball intentionally. [4]










































Run to the field to play again, but don't touch the ball before it is touched by another player. You cannot touch the ball you are throwing before it is touched by another player (both from your team and your opponent). So, go back to the field to help drain the ball and attack the opponent's goal. On the other hand, if you accidentally throw a ball at your opponent, immediately press your opponent to try to reclaim the ball. Always follow up on your throws by returning to the field, taking positions and getting ready to play again.












































Reread the rules of throw-in to practice perfect and legitimate throws. The rules of throwing in are not too complicated, but you must always remember them in each throw. Even professional players even cross the field line when throwing in, and this situation is quite embarrassing if it occurs during a match. Following are the legal rules for throwing in:
The thrower must face the field
Both feet must be behind the line and at least touch the ground
You use two hands with even pressure (not twisting the ball)
The ball must come from behind and above the head.
You are not allowed to score numbers directly from the throw-in. [5]
