When pulling the loop ball, you are ready to exert force from the beginning of finding a position, leading the racket, and turning your hips. At this time, the arm starts to move from back to front under the drive of the shoulder. The next step is for the forearm to contract and touch the ball to hit the ball. After sending the ball, it starts to recover, completes one shot, and prepares for the next shot.

One of the mistakes that table tennis enthusiasts are prone to make is to close the forearm prematurely, that is, the racket starts to contract before it touches the ball, and there is almost no contraction after contact with the ball, thus losing the acceleration of the forearm contraction to the ball Action, the circle ball that is pulled out will not turn. Of course, the force of the human waist is also very important when pulling the arc ball. Let’s talk about the forearm action here.

1. Retracting the forearm is equivalent to the secondary acceleration of the racket. It is to give the table tennis ball a greater acceleration, not the most direct impact force. If the impact force is large, it only transmits a certain momentum, but there is no acceleration. If there are too many hits, it will become an attacking ball. If the rotation of the ball is lost, it cannot be called a looping ball.

2. The correct forearm retraction is after the body’s center of gravity is transferred to the foot on the side of the clap hand, and after judging the hitting point, it begins to push back and turn, and the center of gravity begins to shift. At this time, the arms are very relaxed, and the legs and waist are tightened and relaxed. Driven by the shoulders, the arm swings forward with a certain speed. When the forearm is about to contact the ball, the forearm starts to accelerate and contract, rubbing the ball and moving forward until the racket is swayed in front of the forehead, relaxed and restored.

3. The degree of rotation of the pull-out ball mainly depends on whether the forearm is quickly retracted after touching the ball, so if the arc ball we pull does not turn, we can find more reasons in this regard, because most people retract their arms in advance. , instead of starting to close the arm at the moment of contact with the ball.

If the forearm is not well received, it is recommended to practice more forehand attacks, move the forearm as little as possible, and use the strength of the waist and forearm to hit the ball. This action can be used for the arc ball, but the impact is The main becomes friction-based.
