Bluedog I may not have worded it correctly.

I am not talking about technique at all. To me the pushing of the hands and arms is a technique flaw rather than a strength problem.

What I am talking about is during the swing when you are bring the bat into the hitting zone and your hips have started to rotate then you have the bat over the plate. Your top hand is facing up and your bottom hand is facing down. No break in the wrists because as you know that comes after contact and when you are finishing your swing.

If you are taking a swing and when the ball hits the bat the bat will give a little as the ball compresses(two forces moving into each other they bounce away) no matter who you are but with someone who is weaker they will still get the bat through but the power has been taken away.

I am not saying Juniors, Seniors and college players have this problem. I am just saying that kids who are smaller are usually weaker. When you have tryouts and you see a weak kid swing the bat and hit the ball you can sometimes see the bat go backward until he can muscle it back up to finish.

I am not trying to insult the father's kid by saying he is a weakling. I am just saying that when it comes to strength you need core (which I think we all agree with) and arm and hand strength to provide the resistance on contact.

I hope that clears it up as to what I meant.
quote:
.......and arm and hand strength to provide the resistance on contact.


Coach, the ball is on the bat about 1/1,000th of a second.....There is no time for any energy transfer from the hands, resistance or otherwise.........

Practically all (with very few exceptions) amateur hitters push the bat to the ball.......That is why you see what you see.....

Strength in the hands and arms does not matter when swinging a bat.....

One other thing to consider.....The swing is over once the bat contacts the ball.....Nothing matters after that point in time as to the result of the hit.....The finish of the swing is bat/ball contact.....Anything a hitter does after that is meaningless......
With all due respect but you are wrong. I agree the ball is only on the bat for a fraction of a second (if you say it's 1/1,000 then I won't argue that).

Physics will tell you that without something to provide resistence it will give - whether it be compression or giving ground. Plus even with resistence there will be some give (look at a high speed picture of a ball hitting a bat - you will see about 1/3 of the ball compressing and a wooden bat bending. A metal bat is no different it will give). The strength in the arms and hands provide that resistence. The amount of time of resistence is very small but it is there. The older and stronger a player there will be less time on contact but the younger and weaker the player the longer the ball stays in contact with the bat therefore the amount of resistence plays into the type of hit - strong or weak.

And although I feel that this is important what really is important is the core strength. If you can't get your body twisting through the swing quickly enough it doesn't matter.

Look I am not a science teacher but what I am saying is correct. I hope someone else can read what I am saying and help me explain it better.
First - I don't understand half of what that article says. Unless you are working with science on a daily basis I don't think the average person will understand it. What I do get is that it seems that the article is saying it doesn't matter if you have a tight grip or loose grip. I am not arguing that. I tell my guys to get a grip in the middle of tight and loose (like shaking hands).


Second - I am tired of debating. I really doubt I will convince you of my point and I am not going to believe yours either. If I am wrong and someone can prove it in terms I can understand I will stand up and say I was wrong. I know I have been wrong plenty of times and I know I will be wrong many more.

I know I see on TV that ALL players have huge forearms and that goes back to when the old guys played (Gherig, Maris, Musial etc...)

I know that in the Atlanta Braves offseason work out book they give their players they stress core and forearm / hand strength.

If you are right and I am wrong - then so be it. I will have learned something new and will incorporate into my teaching. So far what I teach works.
Coach, this is the important part of the research article.....

"A good part of the reason why this happens is that it takes time for a vibration impulse to travel from the impact location to the handle and back again. Measurements and computer models show that the collision between bat and ball is over before the bat handle has even begin to vibrate and the ball has left the bat before it even knows the handle exists. Finally, experimental evidence comparing the effect of different grip conditions on resulting batted-ball speed conclusively shows that the manner in which the handle is gripped has no affect on the performance of the bat."

More reading.....

OK I can't help it but after reading what you just put on the last post I think I know where we are going here.

Unfortunatley I don't have time to answer right now. I will get back to you close to midnight. I am a high school teacher and football coach as well. We got a pep rally getting ready to start and a game tonight.

I promise I will get back with you.
Dog, Interesting that grip strength (resistance) has no bearing on how the ball comes off the bat. Was this test conducted at various ball/bat speeds as well as different areas of impact on the bat other than the sweet spot?

I guess one way of testing this theory outside of a lab is to literally throw the bat at the ball Big Grin
quote:
I think we would all agree that too tight a grip (taken to the extreme) can inhibit batspeed.


I don't agree.......I believe the hands are for holding on to the bat....This all providing we are discussing a high level siwng.....

In a low level swing, the grip pressure may matter....Since, the hands and arms are producing power.....
Take a death grip on the bat. You will find that wrist action is somewhat inhibited. Anyone can find this out for themselves by picking up a bat and swinging it.

I am a firm believer in getting the hips into the swing. Yet each part of the "chain" (as some like to call it) is important.

Again, this is all painfully obvious. Trying swinging with the world's best hip rotation but without moving the arms. See how far the ball goes. Try using the greatest possible arm exertion without hip rotation. That won't cut it either. Use the best mechanics in the world, but lock the wrists. You won't be hitting very far.

The wrists have a role to play, something to contribute, regardless of what swing philosophy is used.

And before anyone - especially you, dawg - argues. Pick up a bat and swing it.
Notice the bat holding a 90 degree angle to the back forearm from load to ball contact....The wrists do not break.....Inhibiting the wrists (holding the hinge angle) is a good thing....It's good mechanics, grip pressure has no effect on it....

More has never meant better. You can swing the wrong way a million times and will have proven nothing.

If you had swung a bat, then you would not say that the wrists can stayed locked.

Anyone reading this thread can try it for themselves. Then the truth will be evident to them.

Now hush until you get out there & try some swings with your wrists locked. Don't show your face on this thread again until you do. If you won't go out & try it, then just slink on back into the dog house & be a good doggie.

No more discussion until you have gone out & tried it. We will know when you have tried it, because you will come back & admit you have exaggerated.

A way to think of drills that encourage hitting oppo is similar to the preferred way of correcting the golf slice.Ask a pro about this if you do not play yourself. if you do play, you have probably learned that the root casue of the slice is the over the top/interruted/"rushed" tempo or rhythm of how the body coils.

You need to learn how to not "rush" and let the winding and unwinding get timed right.

Yu don;t try to fix the slice in golf by changing grip or twisting the arms/forearms/etc. You need to learn to transition the swing plane from outside in to more inside out.

If hitting oppo, you need to distinguish learning to do this by focussing on better rhythm and timing of the coil/core, not doing it by pushing the handpath.

Pushing the handpath is fine for placment or situational hitting/hitting behind the runner/etc.
Feel free to ignore, or run this by your local pro.

The old Bobby Jones hips and hands swing is the closest to hitting (that and Jim Furyk's swing, moreso Furyk's high school/college swing).

Read BOBBY JONES ON GOLF Especially cause and effect of slice/hook and how to fix them-

-shift weight forward,club still going back
-THEN turn hips open
-drop hands away from target to start down from top
-keep wrists coked until well into downswing


As compared to golf, the reaction time requirement and the adjust to location on fly requirement of hitting result in some differences to shorten and quicken the swing and make it adjustable.

The Jones swing was optimized for timing accuracy (same with hitting) while retaining adequate distance by turning the hips back and forth a lot and accentuating the arm load. Separation of torso muscles between shoulders and hips was minimal compared to modern swing (same with hitting,must avoid excessive separation).

As compared to this basic golf swing, the shortening is produced by minimizing hip turn on back swing and by folding arms up so lead arm forms short swing radius.The backswing is shortened by having the head turned to look out at the pitcher and by the hip cok action that quickly folows the minimal backturn of the hips.

Arm load is then accentuated much more than in golf. In both swings, the backswing consists first of the hip turn followed by the arm lift which are blended. Hitting timing benefits from maxing out the armlift part of loading.

This lift is to the point of elevating the back scap/lowering the front so the scaps can then be part of the necessary on the fly location adjustment.

Rocking the shoulders or scap tilt is minimal in golf but essential in hitting as a way of quick/lae plane matching adjustent.

The other big differences in hitting come from the arm action which is similar to overhand throw - hands break in a way that rpidly stops backturn of hips and quickly causes hip ****,then the big arm lift/back scap pinch/elevation.

How to quicken the swing to follow if interested.
Learned more about my son's swing tonight. The root of his problem may be that he's sliding his hips forward during the beginning of his swing which appears to cause his hands to lag behind his body, therefore making it hard to hit anywhere but to the opposite field. Does anyone have any drills for him to help him stay back and rotate his hips rather the sliding them toward the pitcher?
Sliding hips forward is not a bad thing and you don't want him to stay back and rotate.
Ideally you want him to transfer his weight forward into rotation / foot plant with the shoulders/arms/hands whipping around his front side....Without seeing video it's difficult to assess but sounds like he's not using his front leg/foot properly based on his weight still moving forward during his swing. JMHO
NCMtnBBDad - I was actually being a smart alec on my comment. Sorry about that.

I really don't know of a drill that would stop that. When I picture hips sliding foreward I visualize a hitter who's hips lead the swing. That is the first thing to move after the stride.

I agree with what NYdad said about a little shift not being bad but you don't want them to lead the swing.

I tell my guys to imagine a flexible pole that runs through the top of the head and out through the crotch into the ground (like a horse on a merry go round). They want the pole to be bent backward (not that much) away from the pitcher. As they swing the pole will shift foreward - hips start to open, bring the hands coming down into the zone, front shoulder opening up - when they finish the swing the pole should be slightly bent foreward.

If they lead with the hips they will push the pole too far and break it.

I know this sounds crazy but if I could work with your son one on one it would make MUCH more sense.
Coach2709, weight-shift momentum enhances rotation and believe you'd have a difficult time producing much power without it. I find the merry-go-round theory produces spinners which will generally result in a loss of power and pulling off the ball. The "pole" should be your front side/leg which is established via weight shift and posture which sets swing path will also determine lean i.e. "pole" position.

That is not your son's problem in all probability. You need to replace what you think is wrong with a better initiating move.

His hands are lagging because they are dead at initiation. Your hips are sliding BECAUSE the bat is dragging from a lead shoulder linkage that is not the leverage point to turn the barrel around. Harder hip turns will not catch the bat up they will make it worse until the arm and hand action at initition is right.


Just because the kinetic chain is stated to be hips , torso, shoulders arms , wrist hands doesn't mean that is how the swing gets going. It doesn't. After proper loading the reactive phase all starts at once...at go.

The hips and hands coil and a negative sense
( load) and they start at the same time. The key is that the rotation of the bat barrel at swing initiation is what keeps the shoulders loaded , segments the swing and allows the hips to power the barrel without screwing with the hips.

Even though the hips do go first you fix it by concentrating on making the barrel rotate at the GO! The barrel rotates around the hands AS the hips go. The players will get it in no time if you do this and the hips will be a no teach. The hips are working like heck to do somehing they just cannot do at swing initiation

You will never fix lower body problems if the upper body loading / unloading action is not done properly.

While it is intuitive to try to establish a great lower body move it must be remembered that the bat is moving via the shoulder box and forearm action at launch .

Learning how to load the forearms and rotate the barrel aroung the hands at swing initiation ( instead of pulling with the front shoulder) will allow the hips to support the rotational upper body move.

Until you get that concept( and it takes some work), your son will struggle until eternity .

Lets stop the madness.... I know the hips rotate with power but until they interface with the proper upper body action they will NOT BE THE ANSWER.

That is why so many people fail at this( I was one of them ).

Kidding about.

1. it is not a sister site but a similar site?

2. Kidding that,as a moderator, that you might not allow a reference to another site to provide a comprehensive progressive illumination of an important topic even if both are free sites for the advancement of the game?

3. Kidding that rotation of the barrel at swing initiation " really works well" IMO?

4. Kidding that you mistake that I mean that is a better site...no...just a good thread.

5. Kidding that the post is OK but the reference is not/

6. Kidding that the post stinks based on content but the reference is OK?

7. Kidding that I broke rules of the board manners stated?

I am intuitive but not psychic...

My son was one that was failing also...He is an undersized (5'8") 15 yr old still growing. He has a great looking swing but has always had something missing. I really appreciate the pointer to the thread above...it has opened my eyes to some other possibilties (not sold yet but experimenting). HSBBW has pointed me in many directions over the years (I think it's been 5-6 since "Teacherman" pointed me to Mankin)...without it I would have never started the journey that has "progressed" thru Mankin..Epstein..Set*** and SE. I have not always been a convert but I have been helped by all of these... the approach referenced in the thread above is very interesting... Thanks again

Everyone needs to come to their own conclusions


The poster gave a conclusion that hip slide was the problem causing his son to leave the bat behind.

I offered another conclusion based on doing this probably longer than the poster.

I offered a different approach that we can try.

I hope he will study it, try it, and give us the results to see if he still believes his original theory
