Тонкости работы ног при топспине вместе с Фан Джендонгом, идея видеосправочника и теоретики с pingpangwang.com

Сегодня очередная веха в моем постижении топспина (справа). Здесь видеоролики с фрагментами тренировок Фан Джендонга. А предпоследний - для видеосправочника по технике почти всех ударов( Zhang Jike, Ma Long and Fan Zhendong).

Эти видео помогли мне понять, что первоначальный импульс для удара созадется за счет вращения корпуса относительно вертикальной оси. Чтобы обеспечить перемещение ракетки в одной плоскости нужно перед поворотом наклониться вперед (получается переносный эксцентрик)...

А еще я понял роль стоп при создании вращении. К некоторым видео я позволил добавить скудные коментарии...
А в конце Table Tennis three keys - китайские лубочные представления о суперпозиции импульсов.

По этим двум видео вывел простые правила топспина справа.¶

Fan Zhendong forehand loop | Slow motion | practice

1.Удар начинается с разворота бедер !!!

Рука с ракеткой еще остается внизу, а поворот бедер создает первый импульс для удара.
Ноги при этом задают вращение (вокруг вертикальной оси), никакого "шага вперед" !!! Шаг может быть куда угодно... и любой ногой, но потом поворот бедер.

1. Наклон корпуса вперед (в начале разворота) обязателен!!!.

2. Ноги не выпрямлять !!!
   Полагаю, что их все же выпрямляют при контртопспине.

3. Освоить движение ступней "это вам не лезгинка, а твист"!!!

Здесь то самое упражнение, которое мне нужно делать сейчас. Два шага влево и удар.

Это видео с фреймрейтом 60 кадров в секунду можно смотреть в высоком качестве.

Почему он показывает нам свою правую подошву?

Толчок и Топспин с прыжком вперед (левая впереди)¶

А здесь идеальный фреймрейт.

При толчке ракетка именно толкает. При соприкосновении с мячом нет нимкакого "подруба под мяч"... "Чистое" поступательное перемещение над плоскостью стола.

Топспин нетепичный. Фан прыгал вперед, но при этом старался погасить (компенсировать) переносную скорость тела... Поэтому левая нога в воздухе в момент удара.

Это видео может сбивать с толку неокрепшие умы... Надо по нему сделать кинограмму

"Table Tennis three keys" Episode 1: the first key (basic hard)

• 本文出自乒乓网，原文地址：http://www.pingpangwang.com/thread-130841-1-1.html

Здесь с 14-ой минуты видео самый уважаемый тренер наконец доходит до демонстрации форхендов с переносом тяжести на левыю ногу...
А до этого он объяснял, как мог, наложение относительного (ракетка отн. туловища) и переносного (перенос центра тяжести туловища на левую ногу) импульсов... и как это вредно...

Я это объясняю за 2 минуты (только никто не понимает)...

Но приятно то, что китайские тренеры не знакомы с основами теоретической механики... Здесь я впереди!

Гуглоперевод с китайского на русский понять невозможно. Потому переведем вот так:

Three keys to make technical action problems simple . Our grassroots coaches, table tennis enthusiasts, often encounter technical action problems, the three keys is to solve our technical action in the middle of the flaws .

      What is technical action? All the technical actions, whether correct or wrong, are muscular , rather than normative posture, so the three keys are a solution to the pursuit of reasonable muscle force , so if we can master these methods as soon as possible , You can quickly solve all the table tennis technical problems . Here I will specifically introduce, three keys which three.

       Second, the first key: the basis of force (trunk driven limbs)

      We call the reasonable technical action, reasonable muscle force, first of all to meet the human biomechanical force, the body's physiological mechanics force there is a law that is the trunk driven limbs.

      All the movements of the limbs are driven and guided by the trunk to achieve, and our first trunk to drive the limbs of the key is the basis of our batting force, we can hit the ball from the table that hit the net Surface, first of all to use the power of the trunk, then I specifically talk about the trunk of the action, we take the forehand attack as an example:

      Our trunk refers to the limbs and the head of the part , when we forehand attack the ball, we need to shoot, this time should be driven back to the trunk, that is, we said that the waist drive, when we Ready to hit the ball before the time, it should be driven by the trunk swing, that is, driving back swing, which is the trunk driven limbs. Our shot and swing the action determines the direction of my batting, we can make a simple example:



      We put the ball here, right, the ball is now still, my arm does not wield, see my torso can hit the ball to where to shoot, shot, this is the power of the trunk, We do it again, shoot, hit the ball, this time my arm did not move, but the power of my torso has been applied to the ball, which is the basis of the problem , usually we forehand attack prone to the problem.


      Third, the trunk drive the upper limb force of the key point is: swing to touch the ball of this period

      Especially in the enlightenment teaching problems, that we take the time to lead is not driven torso, but the arm pull , we often do this kind of action, racket, ball, so pull the torso arm movements, a racket Put the center of gravity on the right leg, and this time the trunk does not actually turn back, so the center of gravity in the left when you move forward , your strength is not enough forward.



      I do a demonstration, if I now often have problems with the action to teach the forehand attack the ball, is the lead to drive the trunk, the focus shifted to the right leg, and then we then pedal to waist , pedal turn the center of gravity to move the left Legs, in the process we look at this power is where to go. This is not the main forward, and I compare these two actions.




      The first trunk drives the limbs, first to drive the lead, and then drive the swing, the ball just to the diagonal diagonal. If I was all of a sudden move my right leg. Is the swing drive the trunk, then there will be such a situation, I stood in this position did not move, there will be this situation, and then pedal, turn, this is the direction of our hit with the direction of force is inconsistent, because you do not use The power of the upper torso, you just use the power to shift the center of gravity, you transfer the power of gravity, tread it anyway is not possible to move forward, or else to the left, or else on.

      So the first key is to solve your basic hard problem, forehand attack the basis of the force it to move forward, that is to say that you give it a forward force it can over the network , so this is the first key.

      Fourth, hip rotation is the core of the waist

      Usually we are in the teaching process, see some of the children they have a lot of arms of the mess of the problem, then we first have to check his torso action is not right, check the trunk action is correct first check his hard order is Is not correct, is not the trunk to drive the first swing or swing to pull the trunk. If we check that he is driven by the limbs to drive the swing, it is right. But often he can not be driven by the trunk of what is the reason, that is, he turned bad. What is the reason he does not turn around? He was in the time of preparation he put the focus between the feet, this time he can only twist the shoulder, his hip, we usually say that the waist is your hip .





      The hip rotation can not be substantial , as we all know, if you want to turn, then must have only one center, in order to fully rotated , as we say the right to drive the rotation of the trunk limbs should be the focus in the left leg, that is to say to the left leg For the center of the back turn, this time to turn up, when you hit the ball when moving to the right leg, turn forward to turn up, if you put this focus on the legs around it is difficult to turn up, you can only twist twist the shoulders, so often the problem is that he can not do it torso drive racket and swing the reason is that he will not turn back, the reason he does not go back because he could not find a center, no circle is difficult Turn around , so this is the first time we have to solve the problem of the key.

      Five, with the first key (basic hard) to open the forehand attack the core force this lock

      With a simple forehand attack, for example, you first check his hard order is not the trunk first move, whether it is back shot or before the ball, is not the trunk first move, or swing the first move, adjust this The order of time when you look at his torso action can not do, can not turn up, if you can not turn up, then you have to check his center of gravity is not placed on a leg, if his center of gravity put him in the center Also can not turn up, this is the first key.

      Now we use the first key, the trunk to drive the limbs of the force, to explain a complete forehand attack the action of force:

      First of all, we put this forehand attack is divided into three stages.



        The first stage: turn the waist to bring a shot. In order to turn the waist more fully, we should put the body's focus on the left leg,so there is in the left leg for the shaft after the waist, while the right leg can adjust the position to find the ball.

        The second stage: turn the waist drive swing. When your right leg to find the location of the ball when you move the focus to the right leg to the right leg as the fulcrum to support the body center of gravity forward, this process is the force process. The reason why the ball can play in the past or play a strong completely at this stage,this stage is driven by the torso before the swing, often we called the front is also at this stage. The center of gravity to move the right leg to the right leg as the axis forward force, the role of the ball,the power of the torso acting on the ball.

       The third stage, the ball shot, and immediately turn to the left leg, so that the swing inertia to stop here. When the ball has been out of the ballboard, or our strength has been applied to the ball, the ball has been flying out of the time. We should quickly move the center of gravity left leg, so that the inertial action to the left leg,it stopped, if I do not move the left leg will appear to turn to the head, it is not conducive to continuous attack.

      We again to do the first stage again , and then lead the film, back to the waist drive lead.

      Here we ask Guo master to give us a demonstration of forehand attack:





       Guo master welcome the ball before the force he is in the forward , in the forward, we see his hip, is forced to drive the racket forward, forced forward, but after the ball when the ball has been left, His focus turned to his left leg, stopped his action inertia.

      Before the batting you a little stop, before the welcome, this time hit the ball, the ball shot to continue to swing, the shot, back, before the ball hit the ball, this time is the ball, because with the inertia Continue to swing, the focus to the left leg, it stopped the action, or that he infinite inertia down, affecting your continuous attack.

       This is the force of the batting, our first key to drive the limbs is how to use the power of the torso to fight the ball in the past , where the power from it, from the trunk here, the power from the trunk up, right Legs at this time to support the trunk, the trunk forward, welcome forward, this time on the role of the ball, the ball can push in the past, so that the past, this is what we talk about the forehand attack the forward force of this part. When the ball left the hand, this time the center of gravity along the swing inertia to the left leg, this time because the left leg to support the center of gravity, this action on the brake, and can be a second continuous attack, this is the third part.

      Six, with a non-complete action to show the basis of the first key force

      The following with the ball to Guo master to show us before the ball, the ball to fly over the power of the network is how to use out, we do not complete the action, only the second part of the forward force of action.



       This time Guo master action only forward force of the action, we look at his trunk, especially from the back, you see his trunk, look at this part, this power, this time he did not turn the center of gravity, but he has given enough to the The power of the former batting, and this board is very critical.

      At this time he made the action complete, and then hit the ball after he waved inertia, the focus shifted to the left leg, and you see him in the process, the strength of the forward enough, the forward arc is very Well, the most prone to the problem here is that when you focus on the right leg when the waist forward, not hit the ball center of gravity left, to the left to go, it is easy under the net, this time easy Network, because you turn the power of the trunk, the trunk is not enough strength, so it is easy to the next network.

      Seven, with the first key to show forehand with, with the band technology

      Here we use the first key to explain the anti-pull anti-pull fast belt with the forehand action, we have just done is the ordinary forehand attack, and now if we want to pull the opponent pull over the circle of the ball, or Fast attack the ball, then how do we use the power of the trunk?

      Because the opponent pull over is the offensive force of the ball, we are easily out of bounds, so the strength of our torso is generally the first forward, driving the swing, the ball in the past, this is a joint action of the ball, Force of the batting action, but also the trunk driven swing, so we see the forward move ahead of the first, swing in the post, we asked Guo master to do a demonstration, we see, his trunk down first down, The action of the ball, with the torso to suppress the action to drive the swing.
