The Release w/Brian Manzella & Michael Jacobs

The amount of shaft bend at 1:20......strongly suggests there must be some ATS or throwing action going on....!!!!...?????

Retief puts a tremendous load on the shaft on the DS (according to Flightscope), however I believe MJ was referring to the FATS at Impact.
 
Can one assume that a bent left arm at the top would now be desirable? Like in the old days of hickory shafts.

He does the Goosen move (pulls the hands "in") in the downswing! Oho.
 
Hey Dariusz,

I like your posts and find you are much more knowledgeable than many on the forum think. Just because your English isn't perfect many think you must be talking shite. I bet their Polish isn't too hot...

I agree with wulsy, big time. Dariusz, keep up the good work!

Old hickory era golfers used tight jackets that make it impossible to straighten their arms without destroying the sleeves LOL; this is why Vardon's lead arm looks excessively bent in elbow; nevertheless, the elbow joint is a tricky one; while the arm is straightened the rotational RoM is almost double bigger than in case of where it is some flexion in the joint; moreover, arms are "coming out" of shoulders that are widely apart from each other. Now judge if it is possible or necessary to straighten the arm to the limit.

The best swing motion EVER from a biokinetical point of view.

I agree with wulsy, big time. Dariusz, keep up the good work!

Thank you very much.

Cheers
 
thanks lindsey, i notice jamie sadlowski does the same. what would be the prefered way of getting the hands to go from lowpoint to a more upwards direction

Seriously? How can you use your arms to make the hands go "up" sooner when the right arm is straightening well past impact??
And most exhibit a "stable" axis of the torso rotation through the zone. So FORGET that.
That leaves ONE thing.....The rotation of your shoulders/torso. Gosh, it's SO obvious.

If you held clasped your hands together, held your arms out in front of your body, inclined downward some from horizontal, and ONLY rotated your shoulders about a fixed axis at the upper sternum, to rotate your hands and arms around your torso, guess where your hands would reach their lowest point? Of course, in-line with the upper sternum, the center of the torso rotation! That's like Mechanics 101.

It's suddendly a "discovery" that the low point of the hands is often in-line with the upper sternum?

Question.....Did Homer Kelley even OWN a video camera?

Very good video with all these greats. I bet a lot of watchers sit down and think - wait, their releases look almost exactly as mine before I started to try to correct it which makes me now play bigger scores and spend thousands of hours on the range in frustration (instead playing and enjoying golf) LOL.
BTW, not that long time ago I presented pictures of Bill Mehlhorn and his slap-hinge release (even more blashphemous for TGM "experts" ROFL) and a lot shook heads in disbelief here.
The case is simple - if the wrists do not break after impact there is no natural proper release of the whole kinetic chain. Wrists are hinges and mechanical attribute of a hinge is to hinge.

Cheers

I guess I have to get in here too, slap hinge release and a flip, the difference is? to my uneducated eye they look similar, but Ive noticed this if a great player who slap hinge releases its called that a slap hinge release, if a weekend golfer does that its a flip, am I missing somethng?

In On Golf, Jones wrote about Vardon's swing, he attributed Vardon's extreme bent left arm to aging. At that, Jones wanted an extended left arm but not ramrod straight. Jones' view is that on the downswing, when the hip turn stretches the left side, the left arm becomes straight and remains straight until after the ball is struck. This is seen in Vardon's swing so the extreme bent left arm is, in Jones' words "by no means fatal if the succeeding movements are performed correctly".

And its ALSO a revelation that the shaft is unhinging CONTINUALLY at the wrists through the impact zone in the swing of countless greats?

No, seriously.............Homer never even LOOKED at a video of a great player, right?

Todd: I am no longer sure with whom you are arguing. No one here is criticizing Homer directly or trying to suggest that all his teaching was for naught. But look around at golf instruction today and you will see a HUGE amount of effort put into trying to drag the handle, trying to have lots of FATS at impact, and trying to hit an aiming point on the plane line well in front of the ball. Before this thread a TON of people DID think that you should try to keep moving your hands down way past impact and that nothing was more important than dragging the handle.

If what MJ reports is all old news to you, then that is fine. But for many of us it really does change the way we think about making a good swing. You might think we are idiots then, and that is ok too. But stop trying to defend something that isn't really under attack anyway. It is getting in the way of the rest of us learning.

Todd, it is very unsavory for you to make people feel dumb for being excited about information that is helping them because its soooo obvious to you.

It wasn't always so obvious to me. I've applied myself over many years to learn the answers to questions like "how and what mechanical and human biomechanical factors are responsible for the low point of the arc of the hands?" I'm just passing the information. You don't have to thank me for it. Just don't hate me for it.

Bending the left elbow through impact, which is clearly what Westwood, Goosen, and Sadlowski are doing. It's right there plain as day. I don't think anyone is suggesting that they consciously do this to control low point though.




Oosthuizen does it too, and Angel Cabrera, Ben Hogan, and more do something very similar with their left elbows.

It took me and the thread a couple days but I'm starting to get what will be useful to me...

The concept of moving the club away from the target to start the downswing did nothing for me except sting my hands on some thin shots and embarrass me on some fat ones. I think I always had this move in my swing and overdoing it didn't do anything overly good to my ball flight. What really led to some better shots was to just imaging hitting up on the ball with every full swing. Obviously the feel isn't real. I am a player who fights being underplane, hits a low ball and my hips cleared sometime last week....but when I only think of hitting up on it I am now hitting longer shots that are going much higher and straighter than before...and the sound, oh how I love the sound of this new impact.

Big thanks to Mike Jacobs and Brian Manzella (and the rest of the crew) for taking a long hard look at the science and reporting back to us golf addicts the information they found out.
Keep taking the game from misinformation and random hypothesis back to the physics playground that it is.
 
Wow... look at how much this guy pulls the shaft in TOWARDS him at impact. Swinging it that fast there would be no other way to square the face.
