OOAK Table Tennis Forum

so after 3 complete defeats at my local round robin, it turns out I need to work on my loop and make a loop for placement shots instead of forcing my opponent to lose pts.


but how should I change my stroke? If my stroke angle is X and my stroke length is Y, then would I have to increase X and decrease Y?

too much top spin may help u to decrease y.

wow! too much math. its like you are speaking in code. I understand but I feel like my head is gonna explode. It is easier to brush loop slow. The thinner the contact the easier it is to make a slow loop. The thing to consider is balancing how much spin you create. If you want less spin you still have to loop with enough spin to overcome the spin from your opponent so I would say its a balance.

its possible to loop with less spin with a loop that sinks more into the sponge but the speed wont be slow because the sponge will rebound the ball with more force than if you brush.

P = W÷t
W = Fs
F = ma
a = (v - u)÷t Note: This is usually rearranged to v = u at
T = rF
Note: When two letters are next to each other it means multiplication. This is the correct notation. Take the second formula as an example, W = Fs This is expressed as W = F multiplied by s or W = F x s.

Where:
P = Power (The amount of oomph that is applied)
W = Work (The amount of energy that is consumed)
t = Time (Length of time the Power is applied for)
F = Force (Basically the amount of grunt the shot has. Similar to P but subtly different)
s = Displacement (this essentially translates to Distance, except under certain circumstances)
m = Mass (weight of the ball, fixed at 2.7g)
a = Acceleration (change in velocity over a given time period)
v = Velocity (speed of the shot)
u = Initial Velocity (how fast the ball is hit at you)
T = Torque (The amount of Turning Force that is applied)
r = Radius (the length from the middle of a circle, to the perimeter.)

P = W÷t
In order to gain more power in your shots, you have to do more work or take less time in your shots. The time in a shot refers to the time the ball is in contact with the racket which is fixed at approximately 0.003 seconds. Therefore, in order to increase the Work done, the second equation must be examined:

W = Fs
If the amount of Force is increased, then the Work coefficient is increased. The other way is to increase the Displacement, but that cannot be done as the length of the Table is fixed (technically, lobbing or looping the ball will increase the Work done, as the ball has to cover a larger distance than ball that barely clears the net). In order to increase Force, the third equation must be examined.

F = ma
In order to increase the Force, the Mass of the ball needs to be increased which is impossible, or the Acceleration needs to be increased. In order to increase the acceleration, we analyse the fifth equation.

a = (v - u)÷t
The result of the calculation between the brackets must be calculated first (it's a mathematical law). Therefore you want to maximize the acceleration, minimize the initial velocity. In order to maximize the velocity, you have to hit the ball as hard as you can. The initial velocity is something you have no control over, as it is how hard the opposition hits the ball at you. However, as the initial velocity is coming towards you, its value is negative. So it is actually added to your velocity, as subtracting a negative number actually means you add the two terms (another mathematical law). The time remains fixed, for the reason explained above.

Therefore this demonstrates why the harder you hit the ball, the more Power it will have.

But, speed is not everything in Table Tennis. There is spin, which will has to be discussed.

I hope this was helpful or X ( start ) Z up and down Y forward movement * Increase until desired effects take place.

THAT WAS AMAZINGLY FUNNY!

My hats off to your impressive creativity!!!!

No my freind I need to thank Greg Letts for this on ABout.com. His creative warped sense
of table tennis has created this Math brain fart. But think about it. Is math and physics the key to improving one's stroke. If in deed X is the starting point which I believe it is. then it must look like this::

T = table
A = angle
S = speed
X = zero or start
Z = up and down
Y = forward motion

The formular for a perfect loop T=( XZ)+ ( Y ) + ( SA )

I hope that is just as confusing
Peace GIG

I find this very funny!

Just to revive, I slowed down my loop by slowing down on my blade ( from zlc off ++ to spirit medium fast ). My spin slowed down but become more consistent.

Enjoy the game. It is a never ending learning experience once you play and keep the ball on that 45 sq ft of space or should I say half of that space.

I had a similar issue.. I felt when I went for power, my stroke became more horizontal, hitting above the ball which is understandable but I also realized that i couldn't pull it off all the while. To solve it to some extent, now I am trying to take a slower more upward swing.

I have come to realize that if I just concentrate on taking a "slower" swing, I gain a lot of consistency - especially close to the table - and automatically the swing becomes more upward for a high arc loop. If I concentrate of taking a more vertical swing, I end up throwing it long because I didn't adjust for power.

Maths is good to understand but numbers have a funny way of not relating to how a human body works - while numerically, both X and Y are equally important, physiologically its easier for me to think and control swing speed than swing angle.

Away from the table, this holds but the definition changes - if you take a slow swing away from the table, you better have the full swing going else you wouldnt reach the net but if you do that, you will see better consistency and placement.

Also, this is reverse in case of looping underspin. In that case I just try to take a vertical swing and hit behind the ball. But that is probably because of some other concerns in my own game.

Buying equipment is like getting into a relationship. One night stands are great but you get the most out of it when you work at it for a long time.

A quick tip - instead of thinking of "swing angle" think about "where on the ball should I be making contact".
It will yield more consistent results.

My formula would be different I prefer T = (XA) + (ZS) + ( Y )

Like Einstein said (to slightly paraphrase), it really all comes down to E = M*(HHYCS)

where E = Energy, M = Mass, and HHYCS = How Hard You Can Smash (the s**t out of the ball)

From my personal experience near the table esp. against underspin one got to take the ball later and swing longer but with more brush than hit.
I don't really know how about topspin probably use less force and brush more?

Probably emphasizing one's placmeent game will help slow down the loop..

Now could someone help me to translate this to X and Ys?

i understand actually....


the difference between looping underspin vs looping top spin is only in the wrist, your body and arm should move exactly the same....if you find yourself changing the angle of your arm to loop under-spin you might be doing it incorrectly....

this being said.....you want to slow down a loop....move your body and arm slower....and adjust your wrist accordingly....

practice slowly...loop...slower...and a bit more slower...ask your partner to block back slowly, softly...

Listen to the sound of one hand clapping.
