More Spin in Table Tennis | Spin Serve & Spin Shots - Duration: 15:33.
Welcome to the channel of coach EmRatThich.
Today, I talk about "How to increase Spin in your table tennis shots: serve, loop, push,
forehand topspin, backhand flip.
Geison asked me "how to generate a lot spin in the services like the chinese
players?
The Chinese philosophy says that there are 3 aspects of a table tennis shot:
spin, speed and power.
Spin is the most important of these 3 terms.
The spiny ball but slow is not powerful.
The fast ball without spin is not powerful.
The powerful ball is the ball loaded of spin and
speed.
LQL always mentioned these aspects as the "quality" of the shot.
Due to the difference in philosophy between Western countries and China, the
approach in table tennis is different (for low level coaching only).
In China, they focus first in spin.
The beginner players are asked to spin the ball
in their first lessons.
These lessons are crucial as the beginner players learn to
develop their stroke and their feeling of the ball.
For the young kids, the ball can land not very far, not very dangerous, but at this
stage you must learn to spin the ball.
As without spin, you can't control the ball.
When you improve your technique and develop a good mechanism of stroke,
you can now focus on the speed and power in next step without sacrifice of the
spin.
Look at the quality of Xu Ruifeng's ball, always very spiny.
He is the top Regional level.
His ball is also very powerful and fast.
The ball lands almost near the end of the table.
And at the word top level, look at the ball of Zhang Jike.
His ball is very very spiny and always land at the borderline of
the table.
It's very difficult to return his ball.
The quality is very good.
Spin, fast and powerful.
In Western countries, the approach is different.
Some amateurs players just look at "pro's table tennis equipment" but don't
focus enough in "how to spin the ball".
At the beginning stage, they already use a fast to very fast blade.
They never have enough time to develop a full mechanism
of the stroke.
They can't hit the ball very hard because if they hit hard the
ball without spin will mostly go out of the table.
Their stroke is short and is not fully developed.
By using a very fast equipment, the training is less efficient.
Remember: in the training stage, feeling of the ball is the most important.
I will show you the best way to improve your spiny strokes by drawing these 2
diagrams.
The first approach is: you must learn how to spin the ball first and then learn how
to increase the speed in the next step.
Focus on spin and how to control the ball.
To increase the speed, you must increase your physical strength (more important).
And then upgrade the equipment (only when you reach the limit in physical
strength).
Your level goes up, now you can hit harder.
The ball is faster, spinner, and land farther on the table.
To upgrade the equipment, upgrade the rubber first: choose faster, harder
rubber.
Don't change the blade first, it can disrupt your playing style.
If the speed is not enough, upgrade progressively the speed of the blade.
That's why the equipment of top Chinese players always end up with a very hard
and tacky rubber, but only OFF- to OFF blade.
The second approach which is preferred in Western countries.
Focus first on the speed by using a very fast blade OFF to OFF++
blade, carbon blade.
But the ball has not enough spin.
Without spin is the same as without control which can lead
to lacks of confidence and many unforced errors.
The player can't hit hard and therefore can't develop a full mechanism of
stroke.
I play table tennis in Europe, so I know clearly this problem.
In some clubs, the coach just say "hey, let's do some drills on the table" but
never ever explain these principles to the new players.
HOW TO SPIN THE BALL ? HOW TO INCREASE SPIN IN
TABLE TENNIS STROKES ? The only and the one key point to
spin the ball is ........ ACCELERATION !
There is a good question on PingSkill: "Speed or Acceleration for more spin".
The coach answered "how much time you have and how long your swing can
be".
It seems to me that this question is not fully explained.
Coach Larry Hodges also discussed "You get more spin if you accelerate into
the ball.The players sink the ball into the sponge,
but not graze the ball enough.
Why?
Why "acceleration" is so much important.
There are 2 main reasons:
1.
Table tennis is not a tennis sport.
The ball weight is only 2.7g.
A young player with a medium physical strength can become a world
champion.
Tomokazu Harimoto is the World Junior Table Tennis Champion at the
age of 13.
His ball is very fast and spiny.
It is not because he hits the ball very strong, but it is because he can accelerate
the ball very fast.
It's not how hard you hit the ball, but it's how fast
you hit the ball in a short amount of time will decide the amount of spin.
2.
The contact occurs only in a fraction of second.
To spin the ball, you must apply force during this moment.
The ball touches the rubber, you continue to apply the force by
acceleration, the rubber is compressed, and release this power to spin
to the ball.
All of these process occurs very fast.
That's why the more you accelerate, the more power is transfered to spin the ball.
Mr. Liu has translated the article "The physics behind a powerful forehand loop" in
Chinese Table Tennis Magazine into English.
I have explained these principles previously: Relax before hitting the ball, body force
rotation from the hip, power from the ground, grip the ball loosely.
You can see that these principles are also confirmed by the Scientific researches.
Kojima also publish an article in the Journal of Sport Science "Kinematics of table
tennis topspin forehands: effects of performance level and ball spin".
Very interesting results ! "The racket speed at impact of the advanced
players and intermediate players are not significantly different.
The ability to accelerate the racket in less time is an important
factor that affects the performance level."
Kojima et al., University of Tokyo
This result is also cited in another research.The ability to accelerate the racket
rapidly during forward swing is an important factor for increasing ball speed
and spin.
VUONG Linh-Son, Master in STAPS, coach sportif, also analysed this aspect.
Dans ce sport, qui privilegie vitesse et anticipation, la rapidit� d'ex�cution du geste et la
capacit� � le reproduire � haute vitesse et � haute fr�quence vont �tre primordiales.
Il semble int�ressant pour le pongiste d'�tre capable a'acc�l�rer.
Le pouvoir d'acc�l�ration de la raquette lors d'un coup est un facteur de performance
important dans ce sport.
car il induit une augmentation de la vitesse et de l'effet de la balle.
It's worth noting that the speed and spin does not come only from the rubber, they come
also from the blade and the technique.
The blade helps you to transfer the force from
your stroke to the rubber.
The technique requires you to make a follow through and
rotate your hip.
The follow through occurs from the moment the ball touches the racket
to the moment before the ball leaves the racket.
The follow through is the main force that makes the ball go forward which contribute
mainly to the speed of the ball.
That means at the moment of contact, you should accelerate to spin the ball, and you
should also rotate your hip to make a follow though to increase the speed.
Rotating your hip is faster than snapping your forearm and
will definitely help you to accelerate at the moment of contact.
Furthermore, the mechanism of this action will "lift" the ball and make the ball go
forward.
The "lift" force also spins the ball.
Fix the position before hitting the ball.
Hit the ball very fast at a short amount of time.
Use the hip to transfer this force.
Continue the follow through to make the ball go
forward.
Now, you understand the best way to improve in table tennis.
You also understand why the Chinese technique is superior: the use
of the hip, power from the ground, relax before hitting, explode at the moment of hitting.
I've explained these tips in the previous videos.
And today, I show you some scientific research about these aspects.
So please remember, "spin" is the key in table tennis.
To make the ball spin, think about "acceleration".
In your training sessions, try to accelerate at the moment of contact in
your shots: top spin, backspin push, flip, backhand topspin, counter loop, aggressive
block, chop.
You will realize that the quality of your shots increase dramatically.
You can also do much more easier now some shots (for example backhand
flip on the table) that struggle you before.
That's it for today.
And the final word, I always say to my players: "In Spin We Trust !"
See you next Sunday.
Coach EmRatThich.

Governor Wolf on Travel Ban Executive Order: "This Is Not Who We Are." - Duration: 1:52.
I'd like to introduce you to Dr. and Mrs. Assali.
They are Pennsylvanians.
They have been living in Allentown for decades.
Mrs. Assali's -- one of her brothers is a 25-year veteran of the U.S. Army.
He fought in Desert Storm.
Dr. Assali's brother and sister-in-law had been working for an immigration visa for the
last 13 years, since 2003
and yesterday, were denied permission to enter the United States here in the airport
in Philadelphia.
This is not who we are.
Pennsylvania is a place of welcome.
The United States was set up to be a place where people could escape oppression.
This is not a place that people come to experience oppression and that's what their
family members experienced.
I for one, as an American, as a Pennsylvanian, I'm outraged.
This family has done great things in Allentown for Pennsylvania and I think it's a dark
day for all of us.
I've been here for many, many years
and I am devastated what happened to our family.
We have done everything by the book and by the rules and what America --
wanted us. We always lived by the rules all our lives and I was saddened and I'm heartbroken because
they had to be sent back to the war zone.
We were so excited to have them, they were only an hour away.
To be put on the same plane and sent back after 18 hours of flying and a long, long road
of traveling.
I'm glad that they are safe at this point and I hope that this doesn't stay because
they don't deserve this and we don't deserve this to happen to us.
