You can develop a base setup by training straight in shots with draw, stun and follow. This will make you better at those shots in a practice setting and hopefully transfer to matches. The nice part of the shots where you hit in the vertical center of the ball is that you don't have to judge...

As long as you know what movements that's involved and how they sequence I don't see any reason to categorize the pool stroke either as a pull motion or throw just as you do with the basketball example above. This is the stretch shorten cycle and that is present in all forceful muscle actions...

I think that it encourages a straighter stroke where you try to have your hand movement pushing in the direction of the COM of the cue in the froward stroke. I don't know if it makes a player better but I think that a coach has to understand it in order to choose which stroke pattern he or she...

If I don't have any extending or flexing of the elbow just have a steady arm and move from the shoulder I would consider that a pushing motion. And its pretty much what I do when i break. But I don't understand what makes a stroke a "simple throw" and why all throws are pulls. Shot put and...

Yeah pretty but I still don't understand what you mean or how do you define the pronated grip. You have the capacity to use a more detailed language but you don't and then you complain that others are not using the terms correctly. Can you define the following questions? How many degrees from...

One more Fran vs Wobbly nonsense discussion. This will help so many players understand our game better!!!!!!!!!! Maybe you two should talk in PMs until you solved your dispute instead of destroying every thread in here.

You could do both pulling and pushing motions in order to apply force to an object. If you throw a ball to the ground you would extend your elbow (push) and extend and or adduct your shoulder (pull). But that's from a human movement perspective. If you change the frame of reference to the cue...

Nice, then I'm going to stop answering your questions :)

Any force thats not in line with the COM wants to rotate the cue. I haven't said it will rotate, only that I would avoid forcing the cue in that way.

Not really, I use shoulder motion through the back and forward stroke in order to keep the cue more level. More like a piston with a little bit of J-stroke, but in a bigger arch than a pure pendulum. When you pull on something it wants to line up with the direction the force. But if you would...

Just trying to minimize vertical motion of the cue through impact and after. On some long strokes the cue is raised a bit just in the end of the backstroke but i would like to see the cue go toward the point of contact as soon as possible after that.

For example: If you're trying to use a true pendulum motion your forcing the cue upwards through impact in order to undo the downwards motion you put into the cue in the early stroke forward. The geometrical modell shows a straight part through the ball put the force you put into the cue has a...

A classic pendulum has its weight on the end of the rod or string then you can apply the force directly to the weight without producing any torque. With the weight in front of the hand the cue will want to rotate around its COM. A lot of the force you apply to the cue will not result in any cue...

Thats not the distinction to focus on. I think that in cue sports coaching in general theres not a lot of focus that the cue is being pushed or has weight. When you see the classic diagram of the motion of a pendulum stroke only the geometric of the stroke is considered not how the player has to...

As said earlier in the thread its not the fact that the player is pushing or pulling. It's the fact that the cue is being pushed that matters. In my view it has a lot of implications on the strokes that I would like to teach and what mechanics I like my players to use.

Physics. It matters because it explains what happens to the cue when you apply force to it.

So if we only focus on the cue and the force the body applies to it, not how the body applies it, its pretty obvious that the cue is being pushed. This is important because any force applied to the cue thats not in line with the mass center will result in a torque around the cues mass center...

I personally tend to think about the stroke as a stroke. The cue has its center of mass between my two hands and my back hand is the point where i apply force. So if the back hand is leading the center of mass of the cue that is a pull (backstroke) and if the center of mass is leading the hand...

Maybe off topic, but how do you pull a cue through the shot?

In sport biomechanics theres a concept called kinematic sequencing often it occurs in a proximal (close to body) to distal (far from body) way. Think about a javelin thrower where the hand its the last segment to flick away the already fast moving javelin. I think cue speed is very important in...
