How to serve and play the table tennis arc ball?

1. Forehand plus turn arc circle ball: (take right hand as an example) left foot is in front, right foot is slightly behind, both knees are slightly bent, the center of gravity is about the right foot. Arms naturally down straight, racket shape slightly forward, when the ball bounced from the table, the right foot stomped on the ground, waist to the upper left rotation, the upper arm to drive the forearm to the left front of the upper accelerated swing, the moment of striking the ball, the momentum of the entire body transferred to the wrist, the acceleration reached its maximum. At the beginning of the descent of the incoming ball friction ball in the middle or upper middle.

The center of gravity shifts to the left foot after the stroke.

2. Forehand Forward Curve: The stance is basically the same as that of a spinning curve. The arm's lead is a little higher than in the case of a spin ball, and the racket forms an angle of about 80 degrees with the ground. When the ball bounces off the table, the legs, waist, upper arm and forearm transfer momentum sequentially, and at the moment of hitting the ball, the wrist turns inward and forward slightly, the acceleration reaches the maximum, and rubs the upper middle of the ball in the late rise or high point period. After hitting the ball, the center of gravity shifts to the left foot.

3. Straight plate positive rubber forehand arc ball (commonly known as small topspin): basically similar to the reverse rubber arc action, but because of the positive rubber particles raised, the friction coefficient of the rubber is less than the reverse rubber, the lack of viscosity, the touch area is not as large as the reverse rubber, if the friction is too thin, it will be easy to "slip", so in the batting to strengthen the wrist rotation, to expand the racket to contact the area of the ball, which is the biggest difference between the positive rubber arc circle and reverse rubber arc circle. This is the biggest difference between the positive rubber and the negative rubber. In addition, the positive rubber arc circle movement is smaller, the forearm force is mainly, the arc of the ball is lower.

4. Forehand Side Spin: The preparation posture and the whole body force method is similar to the spinning arc ball, but when hitting the ball, the friction ball on the right side, the beat shape is slightly tilted forward, and the arm from the outside of the right side of the left side of the upper left front (approximate to the arc) force. When pulling the side spin ball, if the ball hit the right center or the right upper center, the ball is pulled out of the side topspin; if the ball hit the lower center, mainly inward and forward to the main force, often pulled out of the side of the downspin arc ball. In practice, some excellent athletes often use.

5. Non-rotation arc ball (also known as false arc): Beginners can master the action of the arc ball on the basis of a plus-rotation arc ball, the shape of the beat a little bit back, touch the ball in the middle of the lower part of the arm, arm tense a little bit of the forward upward push and pull the ball can be pulled out of the non-rotation arc ball.

6. Cross-court backhand: Stand with your feet parallel to each other or with your left foot slightly behind you, knees slightly bent. Before hitting the ball, draw the racket under the abdomen. When the ball bounces off the table, take the elbow joint as the axis, swing the forearm upward quickly, combined with the power of the wrist turning upward, rubbing the middle or upper middle of the ball in the descending period. During the hitting process, both legs are stomped upward.

7. Straight racket backhand: Because the straight racket backhand is hindered by the body, the arm strength is limited, so it is difficult to pull out a high-quality arc ball like the horizontal racket. With the development of table tennis and the strengthening of Chinese straight racket athletes' sense of innovation, in order to make up for the shortcomings of the straight racket backhand technique, many athletes have begun to utilize the new technique of pulling the arc circle ball on the reverse side of the straight racket backhand by taking reference from the characteristics of pulling the arc circle ball on the backhand side of the horizontal racket. It may be difficult for beginners to master this technique, so we only introduce it to beginners as a kind of technological innovation in the Chinese table tennis world, and hope that more and more beginners will try this new technique so that it can be popularized. The method of action is as follows: stand with both feet parallel or with the left foot slightly behind, both knees slightly bent and the center of gravity is low. Before hitting the ball, the racket is led to the bottom of the abdomen, the elbow is slightly convex forward, the wrist is down and inward, and the racket is tilted forward. When the ball bounces up from the table, take the elbow joint as the axis, the forearm swings forward and upward rapidly, the wrist turns to the right front and top at the moment of hitting the ball, and rubs the middle or upper middle of the ball with the opposite side of the racket in the early or late stage of descending. After hitting the ball, the center of gravity is placed in the middle of both feet.

(2) Q: What are the problems of pulling the arc ball? How to correct it?

Answer:1. In the process of pulling the racket, the angle between the forearm and the upper arm at the elbow joint is not open, but pulling the elbow back to pull the racket, which affects the power of pulling the ball. In training, consciously put the forearm down, with the rotation of the foot and center of gravity movement, the effect of the lead will be better.

2. Before hitting the ball, the waist rotates backward too much, forming a discus-type preparation posture, which affects the forward power. In practice, as long as you feel the center of gravity of the body can be shifted to the foot on the side of the ball, you can.

3. When hitting the ball, the racket is too forward, the friction ball is too thin, so that the power of the ball to reduce the accuracy of the reduction, easy to hit the edge of the racket, the phenomenon is often referred to as "flying saucer". When hitting the ball, the racket should not lean forward too much, and pay attention to the wrist inward and forward rotation, so that you can pull out a high-quality arc circle ball.

4, pull the ball process, the arm from the back of the direct forward swing, into a nearly straight line, it is difficult to create the arc of the ball. The correct swinging method is to swing the arm from the right back to the lower part of the elbow joint as an axis, to the left front above the swinging trajectory is similar to a "small arc", which also partly reflects the connotation of the technical term of the arc ball.

5. Shoulder tension and stiffness. Because the action of the arc ball is slightly larger than the general attacking action, it is necessary to do after pulling the arm, especially the shoulder should be quickly relaxed and restored, in order to facilitate the continuous pull and improve the hit rate of the pull after the kill.

(3) Q: How to practice pulling the arc ball?

Answer:1, unarmed imitation of the action of pulling the arc ball; 2. a person sent to the center of the introduction of the downward spiral ball, another person to practice pulling the arc ball; 3. a person to push, another person to practice the arc ball; 4. a person's forehand attack on the ball, the other person to pull continuously; 5. the two against the rub, fixed a rub in the turn to pull; 6. a person to peel the ball, the other person to pull continuously; 7. the above exercises, the first pull a fixed point, and then pull a non-fixed point; 8. the first time to pull a fixed point, then pull a non-fixed point; 8. the first time to pull a fixed point, then pull a fixed point, then pull a fixed point; 9. the first time to pull a fixed point, then pull a fixed point. Fixed point; 8. On the stage continuous pull topspin ball, gradually transition to 2/3 stage; 9, two points to a point of push and pull exercises; 10. Different landing points to a point of push, pull, attack exercises; 11. Pulling exercises; 12. Serve to grab the pull exercises; 13. Receive the ball to grab the pull exercises; 14, pull, buckle combination of exercises.
