This episode of teaching Shifu mainly explains the speed issue among the five major elements of table tennis, explains the relationship between strength and speed and rotation, and demonstrates the dialectical relationship between ball speed and reaction speed. If you want to know the details, please pay attention to the teaching content of this episode.
Speed refers to the speed of the ping-pong ball flying. The speed of the ping-pong ball is affected by force. The greater the force, the faster the ball's speed, but the speed of the same force hitting the same ping-pong ball is different.
When the direction of our force directly penetrates the center of the ping-pong ball, the ball's speed is the largest. Under the same force, but the direction of the force deviates from the center of the ball, the ball's speed will be relatively slow, but it will increase the rotation of the ball. Therefore, we can see that during the operation of the ping-pong ball, it is always accompanied by rotation. It is not said that 100% of the ball is penetrated, and 100% of the ball is hit without rotation. As long as your power is not completely passed through the center of the ball, it will produce tangential force, and with the tangential force, the ball will definitely rotate.
We know that strength can increase the speed of the ball and change the rotation of the ball, and rotation and speed are also inseparable, because the ping-pong ball has a higher rate of rotation.
If we want to hit the ball purely by impact, the arc of the ball is relatively dead. Only by creating a certain arc for the ball and giving a certain rotation of the ball can we ensure that we have sufficient speed to let the ball go on the stage. This is why the current front-pull arc ball is not only fast but also strong rotation of the ball.
There is a saying that martial arts in the world are only fast and fast, and the same is true for table tennis. In high-level confrontation, we can see that the speed of the coming ball is very fast. There will be a good round in a second. How can athletes react so quickly at such a fast speed? This is what we call the athlete's prediction ability. The prediction ability is based on the athlete's years of training and practical experience that allows him to react quickly within a few thousandths of a second. This reaction is an instinctive reaction. It does not require much thinking. When the opponent serves the ball, he can immediately determine what rotation the ball is, and when the opponent swings the ball, he immediately knows what landing point the ball is to hit.
So from a physical perspective, the speed of a table tennis ball is just how many meters it flies in a second. From a conscious perspective, it can also refer to the athlete's reaction speed. Although the ball is not fast, your reaction is very slow. Compared with the athlete, he thinks that the ball is very fast. Although the ball is particularly fast, the athlete's reaction speed is very fast, so he will feel that the speed of the ball is not fast either.
