Is table tennis a big arm or a small arm? A problem that has plagued amateur golfers for many years.

The debate about "big arm with small arm or small arm with big arm" has never stopped. This topic really bothers many people. Some people have this question because they are deeply influenced by China's traditional fast-break style. The swing is out of order. In the past, the coach of the near-table fast break was forbidden to use the big arm, so the loop ball had to be replaced by the big arm. This is the reason why the order of swinging and hitting the ball is chaotic. Let's briefly analyze the swing order of fast break and loop ball, and then compare it should be clear at a glance.

First, fast break

Turn the waist and lead the racket (small amplitude), swing the forearm (mainly forearm contraction) to the lower left eye (tiger's mouth). This process begins with turning the waist to lead the racket and then turning the waist, and the arm is controlled by the waist, but the arm begins to exert its strength, but it is far from the maximum. The big arm is responsible for bringing the small arm down to the left eye. Here, the position of forearm contraction is the key to determine forearm strength. When the forearm contracts below the left eye in the fast break, the speed of the forearm is emphasized and the ultimate strength of the forearm is ignored.

That's why the former coach banned the use of big arms and fast breaks. Only speed has no power. It is also realized that the forearm is in charge of speed and the arm is in charge of strength; From here, we can further think that if the forearm is retracted above the left eye, won't there be speed and strength? Therefore, judging from the current technical trend, the fast-break play at that time was really backward, and it is not surprising that coaches have this limitation (not to mention amateurs). Let's look at the loop ball again.

2. Loop ball

Turn the waist and lead the racket (with a large amplitude), and swing the forearm to the top of the left eye (tiger's mouth). This process starts with turning the waist to lead the racket, and then turns the waist to control the arm. The arm begins to exert its strength, but it is far from the maximum. In order to give full play to the arm, the key is to get to the position where the forearm can fully release the arm strength, that is, above the left eye (the tiger's mouth holds the palm). In this way, the big arm can be brought up, and the speed and strength can be exerted. This is a necessary action for modern coaches to emphasize the loop ball, and then there is the rotation of the wrist supervisor.

To sort out the wrist friction, we have to start from the beginning. At this time, the arm drives the forearm to exert its strength (the strength is far from the maximum, but it has just begun). However, this force is a process of gradual acceleration from slow to fast. When the racket touches the ball, the wrist can be fully rubbed to complete the key technology to improve the quality of the loop ball from horizontal grip to vertical grip. Only when this link is completed can we talk about retracting the forearm and releasing the arm.

Three. abstract

Whether it's fast break or loop ball, it's all about the cooperation of all parts. Remember: only big joints have small joints, and there is absolutely no saying that small joints have big joints. For example, the short ball near the net is mainly the wrist, and the forearm of the big arm belt extends into the table and is completed by the wrist. The wrist has no forearm, let alone a big arm, only one finger; The proximal table mainly relies on the big arm to drive the small arm to retract (the small arm is used more than the big arm); Cosco Taiwan is dominated by the big arm, supplemented by the big arm driving the small arm.

Finally, a careful reader may ask: Didn't you say that there are small joints in the big joints? Why does it say that the forearm should be retracted above the left eye and the arm should be brought? Isn't this a contradiction?

This problem can be analyzed in this way. No forearm retracts above the left eye, which is said on the big arm. This is because people are limited by the past fast attack technology, and the correct technology that the forearm should be driven by the big arm to swing to the top of the left eye has been obliterated. The coach limited his swing to above his left eye, not below it. In order to clarify the problems left by the fast break, I have to do this, I hope readers can understand. As long as you know what's going on, in short, the newcomers will not go back to learn fast break, but learn loop ball technology. This issue will not be involved in the future.
