- Li Xiaodong (former national women's team coach) in the eyes of convergence
convergence VS conversion
for the concept of convergence, I understand, is a cricket and the relationship between the next cricket, it may be gay ball connection, it may be different ball connection. Contains relatively large range of convergence, convergence of rhythm, strength, have convergence, the first play of a heavy plate of our development effort, the second board the person to return the ball quickly, if I still make every effort to play, the ball may be a combination of is not reasonable, as with a plate medium strength, as long as the shot focused, back to the ball was also very effective, very successful convergence, or the head of a board weight, and then pull a board with light forces turn the ball, also known as convergence.
In fact, the concept of conversion have in common with the convergence, but convergence is more macro, and the conversion, I understand that the continuous use of two different technologies, there are certain limitations of its scope. But the content, the conversion is higher than the difficulty of convergence, such as we put up the offense and defense conversion, literally is the first strike defense, but it is more sought after is the first anti-attack, both of which simple, and even more challenging defensive first strike, as it has been and the defensive after the center of gravity *; attack relatively large magnitude of the racket, when defending a lesser extent; attack easy shot centralized, defense susceptible to .
to speed as the core
convergence (conversion) proposal of the concept, and the World Table Tennis increasingly vicious tactics, rapid development trend related. Among them, the speed remains the core strength is also reflected by a certain speed, so long as it comes convergence (conversion), will emphasize the pursuit of speed.
personal feeling, convergence (conversion) embodies the first few cricket, that is, three, five boards and four, six boards (or two,
mac makeup, four, six boards) relationship, to the use of a most frequently, two to change more. To be entered in the stalemate after nearly Taiwan, and perhaps continuous twenty-three cricket speed, strength difference will not be too obvious, and just different means to play offense and defense conversion differ.
women's team arrived at work, I pointed out First launch is the first force, or the first change lines, or the first control; first start, that is, we have a sense of initiative; through the first start, first launched rob time and space,
nhl hockey, may or may not get started when I get started, it can be to exert or not exert force me the ball, variable line of the ball can be the same line I changed line, and hit the ball the other slightly faster than the pace is always one step.
Wang Liqin lies in the conversion
If convergence handled well, the value of a lot of money, for the players forming the play-style can also act as a catalyst. To Wang Liqin, for example, I admit, he played the understanding and awareness, due to the different style of play focus, relatively speaking, than Liu Guoliang, Ma Lin has some gaps, but I personally do not think that he is playing psychological instability. In fact, the key to the ball handling ability to Wang Liqin, including the spot will and self-confidence is stronger than ordinary people, I think the world championship at this level can hit people definitely excels in some ways, the psychological quality will not bad. His key question, in fact, is the conversion.
his entire play is based on strength, speed, strength-based, height 1.86m, certainly larger range of motion, swing from the president of the general population, coupled with another round of shots in rapid So he made fast to restore power and rhythm of the difficulty of grasping each other accordingly more than other people's congresses, layman's terms, that is, the human stem 1.7m 1.86m 1.6m people even live, that conversion is difficult.
I brought him to this problem is considered, so the transition into a very important status. He was a tall, run fast, care range, and therefore the introduction of forehand and backhand the ball is relatively easy, especially the ability to play powerful topspin on stage, but dealing with the perception of the ball inside the station can not be achieved Liu Guoliang, Ma Lin's degree because the focus is not the same, that is fierce, the change to win, this is the strength, speed, strength-based. Therefore, the focus of training is to take the front of the ball and the ball the next board integration, the higher the stability of this part, Wang Liqin will play to their strengths more. Overtime was also trained in most ball and converted the ball inside the station, the desks have the opportunity to choose when to play, no opportunity to write about, or put about, split about the purpose or for the next cricket. Of course, the difficulty of the different balls varies from routine speaking, pick their next board after playing the convergence easier, because in an active state, on the contrary, after a short swing the other challenges we must face the chop play or fast, long after the split The first defense of our board to pass, these can also be said is the interface between both can be said to be converted. Why do some people said that once to play Wang Liqin, so that he was The answer is conversion, the conversion as long as he can be stabilized at a relatively high level, his play on both advanced and fierce. He is a typical example of tall, Youyi play near the table in the main, in theory, if you do not have the appropriate technical conditions and physical conditions, this play is more difficult to design, but it is Because he has this condition, so our training is done around this.
VS machine gun cannon
for lack of strength, speed and change-oriented players, convergence may be even more important. Like Kim Taek Soo, Pearson's absolutely great force, and I describe them as artillery - mortars or howitzers, attack machine gun, using its own power, not to give you breathing space, you one or two boards to succeed, I can still score a row three or four plates, the weight you do not fight back. Of course, the
1995 of 43 th World Table Tennis Championships, it was suggested: the requirements of the Chinese team is Kong Linghui average power, rotation in general, lethality is also less prominent, but the speed can be. Today, in retrospect, Linghui has been able to succeed, from a technical point of view is the interface between the board and the board fast. Supplemented with the speed of convergence as the primary means of rotation and can score, Linghui should be the first, walking in the forefront of the anti-plastic players.
Again Tan Rui afternoon, as the male players, so his height is only 1.6m and weighing only 90 kg. Although he is more flexible, but after all, the limited scope of care was the strength in the second team is not strong, but the fancy that he is quite intelligent, courage relatively large, then elected a team. I took him nine months, the most important is to strengthen the link, taking into account the characteristics of his, for he designed to velocity-based play - and asked him to take serve after the completion into a stalemate, or chop to play after the pick inside the station, the time of the first cricket should focus on sudden, hitting the highest point of time earlier than that. Click the ball at the top of the larger forces can effect people, but in the state of the best players, you will find the initiative to attack (except for the opportunity the ball), and the stalemate quickly, the control and anti-control, Best shot time is earlier than the highest point, that the late rise. I just try at this point, to fully tap the afternoon of the sudden Tam Shui, Reiki and change, let him open with a backhand to forehand to create opportunities, and its world ranking has risen to more than twenty, unfortunately, he was the non-technical end reasons not to continue playing.
conversion plate exchange center
horizontal plate: Some people care regardless of forehand backhand, before the station is also the right foot that sent power backhand is good, but when the ball is in hand do not adjust the plate, the one likely to cause Conversely, some players, such as heavy contingent of the South is the original hand, they hit the plate is hand-write some outside the more easily force, but in this era, the loop drive is widely used to write so outer plate more on the
straight: Forehand force should be the thumb, index finger force backhand Tuidang should be. If the index finger is still hard forehand, it is easy to lift the elbow; thumb is still hard to hit a backhand, then adjust the force in the direction of the wrist, only upward, lateral, not down.
personal feeling, whether straight, horizontal plate, fingers, wrists should be converted in the forehand and backhand play a role in every sphere, such as the horizontal plate by the hand back to the backhand is easier, a little downward pressure on the index finger back, while slightly less straight little finger movement. Fingers, wrist auxiliary door effort to convert the diligent practice, because of its small range, the resulting resistance is also small, is conducive to speed, but do not have to stage practice, anytime, anywhere training. Training was also latte beat, I think, as long as attention to relax, this is a good way. If you turn out to be very familiar, coupled with anticipation, a real war would not have too much pressure conversion.
but stressed that the finger wrist secondary conversion, not not pay attention to the center of gravity, and when the ball very fast, as long as the focus of the exchange can be guaranteed, even if too late to back out of high quality ball,
insanity dvd, but also to ensure that the relative ideal ball effect, if the center does not exchange hands might become a regular In fact, if the exchange well, to a smaller exchange, for example, the main sights are in hand to the player, finished his turn after the ball is in hand to attack the exchange well, you can continue without being crushed repeatedly Push-type exchange .
in my opinion, which is a basic category, but some young athletes may be less emphasis on this. Certainly higher than the non-exchange swap hard, playing up points late, and certainly higher than the highest point drop point play early is difficult, but not because of hard, because you do not think the trouble, the good thing is certainly more difficult, or not fair to a statement. In line with the premise of their own play needs to strive to regulate, the pursuit of the best things since childhood, difficult yes, but if the refined theory, do you think it is advanced, it is feasible, is your ability to withstand , and you do it, once you do, you will walk in front of others.
is anti-Delta Delta VS
from Taiwan for the ball into the stalemate, many people immediately go back, pull a pair of claws look like after going to hit a stalemate with others In fact, often because the other side to the ball faster, before the momentum is stronger, causing the ball to you, So, I have a reference training: hands on the table, hands in front of the body, hands in front of the elbow, so I hit the ball position and ball distance is more comfortable.
back and forth for this rapid convergence in the (conversion), you can also use the The people form a triangle with the ball, more accurate way, the human body should be the center of the triangle from the center to the left and right before the top of the swing, so I was in the can guarantee the batting front, regardless of force, leveraging all easy. If the ball into the center of the triangle to extend to both sides of the ball as a starting point, labeled as an anti-triangle, unlimited expansion of both sides after the ball on the big difficulty.
reasonable shot power concentrated
I came to the national team before the men's team in Beijing working for a dozen years, the master is the CEN Huaiguang coach, he holds some of the phase. It is said that the Beijing team strength, is not particularly large number of practice rounds? In fact, we have no intention to pursue training in the swing speed to the number plate, but the research was more on the force, the force is divided into several. For example: Kazunari force, that is, points. We encourage moderate forces and the leveraging of force, and to promote the late hit on the rise, at this point, the rotation of the ball is not completely out, as they are made with the highest power of a good time, and speed, hidden strong , if you wait until the highest point and then shot, slow down, pull big, batting also exposed to more obvious intent. As long as the force is reasonable, turn more naturally to it? Furthermore, the shot should be concentrated, so only guarantee they can fully reflect the sudden explosive. I can not get back the Queen Mother, and will not ward off panic, you could not move me, I borrowed on the strength of two into your service three strong, back to the past, like the power is not small, nor from the scene under the terms of the wind. Find a good place to find a good distance, to create a more comfortable batting conditions, which the conversion is relatively useful.
prominent means of a comprehensive specialty
cohesion or to refined. Such as the Loop in the rally or defensive to offensive, when you near the table station, if the ball's arc is relatively high, relatively strong rotation, the rhythm is slower, with more difficult to deal with anti-tear, a board may wish to use the backhand shells hit - the ball was invented by Jan-Ove Waldner, and later Ma Wenge, Linghui with more than, if the arc is relatively low, more normal rotation, it may be faster with a plate, fast pull (termed anti-tear) to founding the better.
backhand, in particular the anti-plastic players backhand, in the end what convergence means for good? Today's table tennis, not only prominent characteristics, but also stressed that comprehensive technical, backhand in stalemate, offense and defense conversion, only to fight against tearing or shells are not enough, the rotation is very strong, the arc may also be using a very low level gear, system because of the ball should be. Of course, three or four instruments can not be evenly distributed, or to form their own strengths: strong if the anti-tear, anti-tear larger than the important, if the ball overwhelmingly to tear, you can anti-tear, friction can be struck You may use more friction, and vice versa, a strong ability to impact people, hit ratio to a little more. From the trend, now is the era of speed and rotation, I personally think that the threat and rotation of the ball bigger. For example, Liu Guoliang beat creating a straight horizontal precedent, the original can not pull down the spin backhand, he can pull the original block are flat backhand rally, he can beat, but because of the relationship between age and style of play, his backhand friction capacity is relatively weaker, and Wang Hao, Ma Lin, Yan Sen now only knock on the slow rhythm of a board, stand-in is less knock, and are based on a combination of rotation and speed of methods, such as each other after we pull loop to anti-tear, the other soon after we pull flat block or quick tear.
each other One World
I have a point - and more focused, nothing more than pro-active, fierce change. We all like to go to Beijing, my approach may well point, be considered to go from Shanghai, I went, he walked from Hainan, though slowly, but it is also in the walk, the final destination is still relatively consistent. We are in each other, why Waldner on the world table tennis a relatively large contribution because of his attack part, the backhand loop missile hit, receiving Akira are written so widely used, and similarly, Chinese players are also many things to learn from European players.
example, Samsonov is tall, the overall strength of the strong to my personal observation, he is also in solving the problem of convergence. He used the method, first used more long-ball open, for in the last rotation of the convergence of (conversion), try to avoid near and far, the desks and the introduction of this kind before and after the distance transformation, so that in the original position choose to play, write, and then the formation of Long ball spin exchange that is easier, which is similar to Wang Liqin; Secondly, Samsonov pay more attention to each of the technical quality of cricket, such as splitting long cut very deep, shot fast, relatively strong rotation, or rally make each other feel the ball in the very Of course, the conversion is relatively easy to backhand resolved, but he is still among the more obvious a weakness, which is the center of gravity, the shift has a very high demand for tall people who are difficult to resolve.
I had done a rough statistics, taller players, the woman taller than 1.7m, men more than 1.8m, and is generally considered to be more soft and slow. But Wang Liqin still retain the advantages of normal height, so good foundation for developmental players, at a young age must strengthen the physical training, and now you may feel in your body can use, but may not be maintained in future , particularly girls, after development, the body fat, if guts and then a small point, It will be physical insufficient. In other words, in small, even when the body can use, but also to reinforce to advance more, because they wanted to convincing.

Li Xiaodong - coordination of the six key words < p> Li Xiaodong - coordination of the six key words
of: Li Xiaodong
the beauty of sports are sports, athletics have practical needs, how the two combined? In my view, the wealth of table tennis tips and techniques for movement, coordination is the answer: just action hit rate is not high, it can not be called coordination. - Coordination, a symbol of ornamental achieve a high degree of external unity. Table tennis is the body movement, the number from the bottom up, ankle, knee, hip, waist, shoulder, arm, forearm, wrist, fingers ... .... Are indispensable, legs, hips, waist and more of the coordination of large muscle groups force, while the table tennis ball of light, fast, feeling fine, so the feeling is also very important nerve endings, the ultimate strength of large muscle groups to be reflected by the small muscle groups? This is the test of coordination.
the basis of a child playing well coordinated, twelve, three years into the professional from the sports school when there is hope for change, such as wait until the fourth, five years into the national team, to change the action in the often deeply embedded and with little success. Therefore coordination is good or bad, it means that your wide or narrow space for development. Moreover, the coordination is good, you can afford will increase the relative intensity of the exercise load and help reduce the incidence of injury, for example, stands to reason that the shooting side of the ball in the shoulder hold is usually calm, But some lack of coordination actions, play, play pretty on the outside shoulder first, unreasonable use of the shoulder, resulting in excessive force, there sick, in fact, of the point should not be there in the shoulder.
to strengthen the coordination, there are six key words that can not fail to mention:
moderate grip both homeopathic order
the body and the racket grip convergence point, where a difference of anything, your actions shape, the feeling of the hands will have a huge hit and even decisive influence. If the grip is unreasonable, it is easy to make the action tight, direct impact on actual performance. Take Japanese straight, its grip in the back three fingers straight withstand, so fight back in hand to exert a stronger ability to put the ball, very smooth, but to the backhand, the desks, will be limited, hair stiff, uncoordinated.
regardless of grip, must pay attention to homeopathy, order. Such as the candy bar's grip, the index finger. Middle finger,
vibram five fingers, jaws of death three-point, three of its two index and middle fingers, the ball is in hand to attack the role of very large, if Talia hard on the same line at the same time, it will produce resistance to each other, undermining the coordination of movements, At this point, if it helps with the thumb turn, the effect will be better.
most controversial, or on the forehand and backhand shots shape the need for exchange. My personal view is to moderate, balanced and reasonable. Back and forth in quick, you said not the slightest changes in grip, but also take into account both sides, I do not think it possible, still need some exchange; Conversely, if both sides of the exchange too, I am afraid it is too late. Or as straight as an example, Forehand role when the thumb relatively large file if the backhand push, the ball backhand attack relied on the thumb in the thumb, it will hid the ball, the result, many people go to the backhand when the index finger force , thumb stuck up, not knowing, thumb Alice was high, in exchange for the forehand will be affected and, therefore, unreasonable. The same people who pay attention to push the files in the file index finger to push hard, no question, the question is, if Forehand Shihai play a decisive role to the index finger and middle finger, with the tiger's mouth is difficult, and likely to cause behind the ball, carrying the elbow, shaking. Horizontal plate, too, if the grip is very deep, with Japanese style candy bar similar to the attack could put the ball in hand, Loop relatively stable, but the chop was rotated, the ball was handled inside the station will be stiff; if the grip is very shallow, a good control of the ball inside the station, but hit back the ball put the power of qualitative issues are also easy to produce. Therefore, when the grip, and comprehensive consideration to the relationship between the forehand and backhand, basic grip will not be much change, but the actual application of certain requirements in the fine adjustment, especially the fingers, wrist to play a role.
to find a proper grip is not easy, but the grip on the minor improvements to the overall technological level of exchange may have great potential for high yields, some effort is worth it to spend more .
the same time and same upper limb to the
p> table tennis ball hard, basically a power transmission from the bottom-up process, to put it mysterious point where some describe as the martial arts, the power from the legs through to the wrists, fingers, and this runs through the must have skills, should be barrier-free, and can exert both a regulator. Many girls do not play hard when the bottom, arms wide *, * upper body, back to the ball easily made air, hair floating. Therefore, we promote from the lower body began to mobilize, because the greater lower body strength. With the upper and lower extremities, to promote the coordination of movement is essential, and I classified them into two identity - upper and lower limbs at the same time, development effort in the same direction. Thus, the use of force is more economic and reasonable. Some people, the first leg hard, upper limb after the hard, easy go often appear poor footwork, and is likely behind the ball.
application of this
find someone with the body and hands; hand problems, I first consider the shoulder, as if a stiff shoulder, arm, forearm, wrist, fingers will be stiff; If the shoulder is not stiff, stiff arm You following forearm, wrist, fingers will be stiff; forearm stiff shoulder, the arm is not stiff, your wrists, fingers will be stiff. Some people have stiff shoulders, and he succeeded to speak, stiff, does not.
relatively uniform local fine-tune the trajectory
regardless of which projects, no matter how complex the representation, the principle derives from it, should be simple, clean and clear. In table tennis, no matter what action, body and hands should be running basically the same trajectory, especially in the arm trajectory, I think running in the air, half-way may not be reasonable to change, likely to cause actions to take shape, and occasionally may be able to play one or two good shots, but if things continue in this way as their main action is very unstable.
, of course, the overall trajectory of the relatively consistent, does not negate the need for local regulation, but this regulation should be left to the fingers, wrists to complete. For example, the ball under the net, and my fingers (mainly the middle finger) is more friction up some finger friction is not enough, the center of gravity to exert some upward direction to the center of gravity and friction are not enough fingers, shape might a bit more, but my trajectory is constant. Whether attacking topspin or backspin, whether to exert more or leveraging more, if your action is relatively small differences in shape, integrates more closely with each other, the convergence of your conversion will be of great benefit, action will be more coordinated.
more help focus development effort to help restore
center of gravity and is basically one hand, and by no means isolated. Therefore, the premise does not clip arm, I think hands away from the body if recently, the focus will be able to better utilize the power of the combination will be a little easier, action will be more coordinated. The center of gravity to help force, we are better understood, but in fact much more than the role of center of gravity, both forehand and backhand convergence, serve, chop ... the center of gravity of the shadow at all times. Marin serve well, he said, , the focus point is about the same time in the same direction. , as long as the direction of gravity force down, hitting the time to master, it will not take flight, with only * if the hand of anti-recoil force, shape down to 180 degrees, it may not be useful skid, including Latvia control the arc ... * - focus all your lung power, it can liberate your hand, so that the pressure of the hands of a small number, but also more stable.
my focus to discuss arms reduction is the focus drive. Assumed only to restore the main arm, the arm ball forward rate of attack may be more than two feet or three feet, if the reduction is such a great distance, each playing a cricket, need to work hand to six feet, back and forth quickly after a few board , because the frequency is too high, the hand has been stiff, no feeling. If you can help restore the center of gravity, almost in quick succession was the racket can not fight back, so hand to give greater freedom to use the time saved, you can relax your hand, you can calmly go to compare to find the sweet spot, to get the benefits of digital ... endless.
practice, there is one point often overlooked is that people who pay no attention to the right hand grip with the left half-length, left hand grip the right side of people pay no attention to the cooperation, coordination around weakened. To brake, for example, if the right player finished his force, the left half-length is not room and board power, let the swing with the coherence across the midline of the body, the further reduction of back, too large margin. If the action moving to the center line near the left brake bust a little help, your body will be much easier to restore the right rear, from the forehand backhand return to a similar reason. The human body has many symmetry: the left shoulder back, you can hit the right hand go in front if the top left hand does not move, get out all right; access loop, the left shoulder after the look up left, right hand it is natural to bottom left; including attack the ball, Tuidang ... all need attention.
racket loose but not tight but not stiff Huang
racket with the racket skills. In the process forward after a lot of people blindly to force, starting from the handle, the hand has been in a state of high tension, resulting in the course of the swing, no ability to accelerate, it looks great exert oneself , but in reality thankless, the ball is very stiff, the feeling of the hands, back to the ball results would be poor.
In fact, if the process is divided into two feet in front of welcome, the first - feet, you make two or three nearly fresh enough, the ideal state of Thus, in order to win power for the real shot to win time. The final shot in the foot which will, we must put one foot out the essence of the full show - including the shots hit, rub, turn, create an arc, regulation, all completed in the foot. If you master this, and for improving the sense of space and rhythm are good.
a lot of people on low ball spot, pull the red has to care about a golf experience, even if the bin arm a whirl. But Deng is not, she played any cricket on the arc have requested, which contains a very large fine is small, always strive to put the the ball through their own index finger, press down to send the tiger's mouth, so that arc can be walked from top to bottom, so the hit rate, this is what she jumped to the Department. The more people, highlighting that a foot can not explosive, technical details are not deep thought.
fill the gap consistent pull dry onions
people who play table tennis, extreme point of view, two categories -
a class of people, not the racket, in situ contraction, or a lot of racket in advance, took aim at the lead end, waiting, almost every kick will pause for a board, easy to take the original ground, running staggered start method, is neither smooth and very laborious, a action of the inertia, seems comfortable coordination, which we call
which you want to belong to - class? I'm afraid no one would choose to I understand it, decide whether you can In the course of the ball, the center of gravity should be non-stop exchange, Chung-hing out of a small olive (or date pit-shaped) path is endless, so as to strengthen coordination and improve the ball's objective quality. Of course, the speed of each ball, this continuity in the rhythm a little adjustment to j, do not let it stop: for example, slower ball, your center of gravity can slow down the exchange, the racket can slow down the action slightly larger point, click the ball from the big points, big points to use force, but that does not stop slower, slightly faster than the ball on the line; If the ball is faster, and I motivate to hurry up, range of motion small point initiative to attack, in the distance, center of gravity
to note that this coherence, mainly by the back to front, rather than up and down. High-level players, I say a joke, he played at the height of the body are similar-inch, basically the whole person in a horizontal line uninterrupted motion, so smooth coordination. On the contrary, if the
six keywords discussed in the final analysis, what kind of action be considered a good coordination of actions? So. . . . . . How to do? How to do? What is the reason? .
