Happy Memorial Day Weekend All!

It's been a while since I've posted anything on BowlingChat.net but not much has changed since the last time I've posted. I'm still hell bent on understanding how guys generate so many revs with such little effort. I really believe that if I understood how this happened that I might be able to incorporate some of it into my game. With that said, I ran across the following video of Dom Barrett and I was absolutely amazed that he can generate all the rev that he does while appearing to not try at all. Here is the video:



I'm really hoping that one of the coaches here would volunteer to dissect Dom's swing so that I can improve my understanding of what is happening here. In addition, if there are key points that help Dom achieve this release, I'd appreciate hearing about any corresponding drills one could work on to make this happen.

Thanks all for your feedback. It is greatly appreciated.

Without the ability myself per se, I'd say Dom is biomechanically efficient as are most elite bowler's of slight stature.

Have you studied the ETBF videos?
Those videos illustrate why Mark Baker, likens the release to the center piece of a jigsaw puzzle. In essence, your timing, your footwork, your swing etc are the parts and the release is the sum.
Dom does not fight physics. Most of us can't fight physics. One thought might simply be, ride the ball.
Look at the ETBF videos and the additional video analysis with annotations and overlays , the second video as posted on the wiki.

http://wiki.bowlingchat.net/wiki/index. ... hing_Video

Also if you don't have analysis software, look at the free items Jim mentioned.
You can then dissect, slow down etc.

viewtopic.php?f=3&t=11049&hilit=Kinovea

Also SOMETIMES training with a lighter ball and it props can help.

Love to have Juha or Onder comment.
I've certified USBC in the early 2000's . I was hoping to learn and was disappointed with the program at that juncture. The instructors were great, the material was WEAK! What we need is a program that grooms teachers, ETBF looks like it does. We need a program like that here.
Pure and simple the ETBF is flat out SERIOUS about educating bowler's and coaches!!!

Get the software Jim mentioned, download Dom, compare and contrast with data from ETBF and Mohamed Janahi's video. I think that will help.

I find it very interesting that right at the point of release, Dom's wrist is slightly collapsed, but this obviously doesn't affect his power whatsoever.

Here are a few words from Ron Clifton.
Wrist motion and speed drive the release.
Though it is different, propelling a Frisbee, working a yo-yo, turning a doorknob are examples to ponder.

Read Ron's explanations

Thank you for your feedback on my question. I'm getting ready to take a look at the links you've posted...I appreciate those very much.

In response to what has been posted thus far, I just want to mention how far I've gone in trying to understand how this type of release generates power. As a former math major, someone who is admittedly slightly OCD, and someone who excelled in science in both college and high school...I found it a natural fit to try to dissect how Dom so efficiently turns kinetic energy into rotational kinetic energy without wasting much at all. From a mathematical and pure physics perspective, the "less is more" philosophy makes 100% sense. The ball actually has the most potential energy at the top of the backswing when it actually comes to a complete stop...just before falling into the downswing. This is translated into kinetic energy and reaches it highest kinetic energy at the bottom of the swing just before hand manipulation at the foul line. At this point, I see it as 3 things that can happen:

1) Energy is wasted by fighting the stored kinetic energy of the ball. i.e. turned into heat energy by the body applying forces against this energy, thus being turned into heat energy. This is what happens when a bowler tries to "muscle" the ball. In attempting to manipulate the ball, the bowler must fight the kinetic energy already accumulated during the ball falling in the downswing. The more manipulation attempted, the more energy required.
2) Energy retained and projected downlane. Friction from the lane will reduce this energy until, theoretically, the ball comes to a stop. I.e translated into ball speed
3) The zen of great bowlers...the energy is translated into rotational energy causing the ball to rotate

While I realize this is a gross generalization of the physics at work here, in general, it's how I perceive what bowlers do. With that said, I've tried many of the methods that I've found here and other places online. "Turn the door handle", "throw the frisbee", "spiral the football", and "walk the dog with the yo-yo" are among them. None of these have worked for me when it comes to gaining rev rate.

So, I'm still digging for "the holy grail" of power/revs in bowling. It would be interesting if we could measure the amount of force used by Dom to manipulate the ball in the downswing after it had reached its apex at the top...and at exactly what points this energy was expended. I'm guessing it would be close to zero until microseconds before release

My current theory is that higher rev-rate bowlers actually do this in an effort to clear the hand out of the way of the ball on the way down as to not reduce kinetic energy accidentally. With the hand out of the way, the cover of the ball will fall freely onto the finger tips as much as possible thus creating the most efficient transfer of stored kinetic energy into rotational energy. This is another one of those places where some sort of pressure sensor would be useful to understand just how much pressure, if any, the top rev guys actually feel on their hand in terms of down force from the ball.

cspringer, you may have seen this video.

A side view of the bowler would also be beneficial.

While Sean and Dom are different in stature, the points here shed some light on the generation of force.



If and when I log on to a computer, I will add this to the wiki, unless someone beats me to it.

Ron Clifton's articles give insight and Jim Merrell's articles on the wiki explain some of the release techniques.

Jim's article "Pros play the inside of the ball".

http://wiki.bowlingchat.net/wiki/index. ... f_the_ball

Also, I think you can gain some feel experimenting with a light ball.
Part of the impediment is fear and some things in bowling might very well be counter intuitive.
Having a very light ball to experiment with, might make practice at home more practical.

The ultimate whippet release is accomplished with no thumb inserted.

The ETBF videos are very enlightening, well they are to me anyway.

Oh, if this were easy, these folks would not be deemed elite.



How'd she do dat???


Cheers

If you're not familiar with these tools, they may help you develop that yo-yo/effortless motion you're describing.

http://stores.eileensbowlingbuddy.com/release-trainer/
http://stores.eileensbowlingbuddy.com/r ... n-trainer/

There are videos on youTube to view and help understand how they can be useful. I've increased my rev rate a bit (from 325 to 375), but the best releases are when I'm not trying at all. I may never get to where I want to be, but I am slowly moving forward.

Old habits are very hard to break, but drills (foul line, one step, shoulder drop, backup, etc) can help loosen you up and become more fluid, which to me is the key.

Steve I can well relate to your comment about not trying. Juha comments about people trying to make a release. We are for the most part not trained and groomed properly.
Jim's signature line is the secret.
"Simplify the Motion.....Maximize the Results"

With a little improv and creativity, one can craft tools like the Bowling Buddy tools.
An ersatz version of the free swing trainer, is using a vessel like an aluminum water bottle with a similar cap, simply hook your fingers in the handle ,if your force the swing it will let you know. It can teach you to wait.
https://www.amazon.com/Aluminum-Sports- ... ter+bottle

The ETBF methodology is based on biomechanics and observation of many bowler's.

Hi cspringer, attached is a short analysis using the front on view you provided. A side view and rear view would complete the picture, but you will get the idea.

Dom makes it look effortless, but there is actually quite a bit of work going on and if you've ever tried this release, it is still a physical action that needs to be exectued and not everyone will be able to do it.
