What is a fake loop ball? How to pull?

First, when pulling the ball, it should be friction plus impact, not just friction and dry friction. Second, always keep an eye on the incoming ball, concentrate on the incoming ball and get ready for pulling it. Third, we should carry out multi-ball training. Fourth, the movement should be slowed down during practice. Only when the movement 100% is completed can we realize the role played by the center of gravity exchange. Fifth, it should be noted that the connection is more important than hitting the ball hard. Sixth, the waist strength is greater than the arm strength. When approaching the stage, the forearm should be the main force to pull the ball, and the arm should follow. If you are far away from the table, your legs should be separated more, and your arm should be driven by your waist to rub more and push forward more, so that the ball will be more solid. Seven, it is suggested that we practice pulling the ball more in the early stage of landing, because we are amateurs and the pace method is not so good. Pulling the ball in the early stage of landing will be of great help to us in the game. Eight, we should practice forehand diagonal pull more. Forehand diagonal pulling has the best feeling for the exchange of center of gravity, and the line length is easy to master. Nine, the current pulling action is more from the back to the front. Ten, backhand pull the ball should pay attention to the rotation of the body more than up and down movements.

The development of modern table tennis technology needs "comprehensive skills and outstanding specialties", and curling is one of the stunts.

1, the grip is correct. When pulling the ball, the thumb is pressed down, the index finger is slightly relaxed, and the racket shape is adjusted according to the rotation of the ball when hitting the ball. The middle finger at the back of the racket must be on the top (Jiang Jialiang naturally bends the ring finger and the little finger to the middle finger, saying that this grip is more sensitive), and the ring finger can also assist in exerting force (Li Furong gently touches the ring finger on the bottom plate, and Xi Enting drops the ring finger on the bottom plate).

Note: Don't hold and clap too hard (the tiger's mouth is too deep), which will affect the flexibility of your wrist; Not too loose (the tiger's mouth moves up to the end of the racket handle), which will affect the stability of the racket pattern.

2. Stand still. The basic posture before forehand pull is that the left foot is slightly in front and the right foot is slightly behind (taking the right hand as an example). Generally, the racket is placed in front of the abdomen, the center of gravity is between the feet, and it leans forward slightly to facilitate the departure. Abdomen, chest, knees slightly bent, but don't squat, keep a high center of gravity.

3. Shift of center of gravity. When the incoming ball approaches the net, the center of gravity begins to move with the movement of the arm. When the center of gravity moves, the waist turns slightly, but don't turn too much. The body has a certain inclination, as long as you feel the center of gravity on your right foot. After the center of gravity moves to the right foot, the right shoulder sinks slightly. The support legs are slightly bent, but not too much, so as not to cause the center of gravity to be too low to exert force. In the process of moving the center of gravity, the waist and abdomen should be closed and a certain tension should be maintained. The position of the center of gravity on the foot is that the whole sole is slightly in front of the outside, which can give full play to the effect of kicking the ground to the left and front.

4. shoot correctly. While the center of gravity moves, the racket moves diagonally to the right and down after passing through the abdomen. In this action, any unnecessary action is useless. Put the racket in the right position by the most economical route in the shortest time. Be natural. The general position of forehand pull is below the waist on the right side of the body and a little behind the middle of the thigh. Keep proper tension on your shoulders. Failure to fully open the shoulders will affect the momentum transfer when pulling the ball. Relax your arms. Forearms and upper arms should not be in an absolute straight line, that is to say, your arms can't be completely straight, which will easily lead to stiffness. However, the elbow angle should generally be between 170, that is, the amplitude of racquet should be large to increase the swing action and radius as much as possible.

In the process of putting, another fatal problem for those who learn to pull the loop ball is to pull the elbow backwards or lift the elbow upwards, which greatly affects the pull. If there is such a problem, we must resolutely get rid of it. ① During the whole racquet process, the elbow joint is almost always in a straight line with the hand. If it exceeds the position of the hand in the front and back direction, it means that there is something wrong with the racquet. The action sequence is that the forearm drives the elbow joint to move, and the elbow joint cannot pull the forearm to move back and forth. (2) In the process of putt, the distance between the upper arm and the body should be naturally pulled apart, and don't pinch the arm, only about one punch away. Putting a ping-pong ball under your arm is to overcome this problem.

5, the correct force. Generally speaking, the force of pulling the ball is a process of momentum transfer. The basic principle of its transmission is: from large muscle group to small muscle group, from the lower part of the body to the upper part, from the proximal end of the body to the distal end. In the specific operation process, the center of gravity gradually rises from the front side of the right foot, from the calf, thigh, hip joint, waist, shoulder, elbow, wrist and finger (with the feeling of instantaneous force penetrating the fingertips), and finally acts on the moment when the racket hits the ball (to maximize the swing force and speed, and explode at the moment of touching the ball), which is the core of the arc circle and will never change. In this process, the hip joint should be pushed forward appropriately, the waist and abdomen should be tightened, and the strength should be controlled and concentrated. Forearms and wrists should be retracted at the moment of hitting the ball, and fingers should hold the ball board at the moment of hitting the ball. When pulling the ball with a straight board, we should pay attention to the action of the top plate while grasping the ball board, so as to concentrate the force on the ball board.

6. Shape and hitting position. Modern table tennis pays more attention to the combination of "rubbing", so the shape of pulling the ball does not have to lean forward too much, which will easily lead to excessive friction and insufficient forward force of the ball. The common shape is that in the initial stage of pulling the ball, the board surface should be kept perpendicular to the ground. At the moment of hitting the ball, with the wrist adduction, the board leans forward slightly, giving the ball some friction. Friction and impact are simultaneous. When LAC becomes an arc circle, the friction is greater; Pull forward the arc coil, as long as there is a suitable arc to make the ball cross the net, it is necessary to increase the impact ratio to make the ball generate enough forward momentum.

Pull-down topspin and general topspin at the hitting position, and the middle part rubs to the middle and upper part after touching the ball; In order to improve the accuracy of pulling the ball, the contact point can be slightly to the left, but never too many sides, which will cause the ball to be pulled sideways.

7. Strike point and strike time. The hitting point is generally on the right side of the body, about one arm apart. When the direction of the incoming ball is 90 degrees, the middle and upper part of the ball is more suitable. At this time, it is easier to exert the acceleration of arm swing, because the arm is the longest and easy to exert force.

When you pull the racket sideways, you should first move your feet quickly to get a good sideways posture, and you should constantly adjust the hitting posture by jumping during the sideways hitting.

The hitting time of the loop ball is in the early stage of the ball decline, because it is difficult to grasp the high point period, the time is too short, and there are certain problems in borrowing power. The hitting time of laga loop ball is decreasing. At this time, there is a long time to rub and make an arc.

Let me talk about the direction of force. Generally speaking, the direction of pulling the ball is forward and upward. But just remember that it is not comprehensive to exert force from right back down to front up. Judging from the projection of the running track of the continuous pictures taken by biomechanics, the moving track of the arm pulling the ball is a semi-arc inclined inward. In fact, it is a process of exerting force from bottom right to top left. This can be seen from the track of elbow joint movement of elite athletes in practice, which is a small semicircle from inside to outside and then inward. So when learning to pull the ball, remember not to move your elbow back and forth, which will affect the quality of pulling the ball in the future.

8. Go with the flow and restore. After the ball leaves the racket, the arm will continue to swing a certain distance. We call this paragraph "going with the flow". Its function is to relieve the inertia of arm strength movement, which has little effect on increasing the strength of the ball, but it is also an essential link, otherwise the movement is not coherent and natural enough, which will affect coordination.

The reset position should be selected according to the hitting situation of the next cricket. If unilateral continuous pulling is adopted, the center of gravity will be tilted to the right during reduction, saving time for the next attack; If you want to attack on both sides, the center of gravity should be biased to the middle and you can move to both sides at any time. The racket is placed in the starting position-in front of the abdomen.

Shoulders droop, waist force, swing to 45 direction.
