Sports Cold Knowledge Issue 4 | Why is the size of table tennis getting bigger and bigger?

November 23,2022.
Q: Do you know how table tennis came about?
A: Table tennis originated in England in the late nineteenth century.
At the end of the 19th century, tennis was popular in Europe. However, due to the limitations of venues and weather, the British brought tennis indoors, using wooden boards as rackets and corks as balls on the table, forming the prototype of table tennis. Early stage table tennis is made by cork, rubber.

Q: Changes in the size of table tennis balls?
A: The celluloid ball that has been used for a long time has a diameter of 38 mm and a weight of 2.5 grams. It has the advantages of light weight, good elasticity, and durability. However, its biggest disadvantage is that it is flammable and the burning gas is poisonous. Since October 1, 2000, large balls with a diameter of 40 mm and a weight of 2.7 grams have been used, and small balls with a diameter of 38 mm have been discarded. Since then, table tennis has entered the era of big ball.
From July 1, 2014, the International Table Tennis Federation stipulated that the diameter standard of the new ball was raised from the original 39.5 to 40.50 mm to 40.00 to 40.60 mm, and major international competitions including the ITTF Open and Finals must adopt A new type of safe and environmentally friendly non-celluloid material. Table tennis has entered the 40+ era.
From July 1, 2016, the ITTF no longer recognizes celluloid balls, and celluloid balls with a history of more than 120 years have completely withdrawn from the stage of history.


Q: Why do table tennis balls need to be bigger in size?
A: The first is to replace the original small ball with a large ball to reduce the spin and speed of the ball and increase the rounds of the game, because the big ball makes the ball speed drop and at the same time, the spin is weaker and the elasticity is lower, and the confrontation between players will be relatively Be more intense, not obviously one-sided; the second is to allow the audience to see the details of the ball and the game more clearly, and improve the viewing experience of the game.


Q: How does the increase in table tennis size affect athletes?
A: The weight of the big ball increases, the rotation speed decreases, and the difficulty of catching the ball decreases, which means that the duel of table tennis players will gradually shift from skill to strength confrontation.
The researchers of the Scientific Committee of the Table Tennis Association conducted an experiment on "the influence of table tennis balls with different diameters on the hitting speed and rotation". The research data shows that: the ball with large diameter is slower than the ball with small diameter, and the rotation is weaker than the ball with small diameter. Therefore, at the same time that the big ball reduces the ball speed, the Magnus effect will be stronger, the spin will be weaker, and the elasticity will be lower. This will have a greater impact on players who tend to be good at spinning the ball.

The size of the table tennis ball becomes larger, and the physical requirements of a pair of players are higher. Second, when changing from a small ball to a large ball, it may take a while for veterans to adapt, and the adaptability of novices will be better.
