Slap-Hinge Release

Posted: Sat 2:54, 02 Dec 2017

Dariusz,
Nice job on your 3 part blog post about the Slap-Hinge release. Was wondering if you ever considered the idea of closing the clubface by last parallel pre-impact and then opening the face through impact in addition to a pure Slap-Hinge release in the vertical plane described in your blog post (i.e. doing opposite of cross over release in addition to the Slap-Hinge release). I have experimented with this and have seen an ~10% increase in power and it is producing a nice "Hogan" fade. This should help you greatly to get rid of your pushes to the right that you had in 2017 and the loss of distance. I would appreciate any feedback on the merits of this idea of mine of a Twisting Slap-Hinge release. The twist from last parallel pre-impact through impact is implemented with supination of left forearm/pronation of right forearm and ER of left shoulder/IR of right forearm by last parallel pre-impact and the twist through impact is pronation of left forearm/supination of right forearm and IR of left shoulder/ER of right shoulder.
Thanks,
Rock

Thanks, Rock, how are you my friend ? Hope all is OK.

Answering your question -- yes, this is one of variations that I personally use SOMETIMES with wedges. You know I rarely implement something that requires an independent conscious thought and my work is not directed at it. TGM called it vertical hinge action, if I remember it well. I am a bit surprised, however, that you associate it with a visible increase of power unless you suffer from too low trajectories.

Cheers, D.

Dariusz,
Doing well Dariusz and thank you.

It is not something that requires any conscious thought or I wouldn't have shared it with you. My mind can track many of the movements in my body during the swing and this is one that I am feeling when I hit my most powerful and straight shots. Your mind and body is capable of doing many things subconsciously when the basic motion is automated, but it is still useful to think through the whole motion so you know what you actually want to do. As you know, it all starts with the ground forces in your feet and toes as when I try to swing standing on ice, I don't hit it very well. The ROM in your body grows as you move away from the ground from your feet, ankles, knees, hips, spine, shoulders, elbows, wrists, and hands so our mind and bodies are quite special in the variations that are possible as when we tracked all of the joints vs time in your biokinetic golf swing theory.

I do everything counter in my body during the backswing and through transition so this twisting slap hinge happens through impact. It works well for pitches as you say, but it also works well for any shot too.

As for helping to get the ball up, that is a good observation. I am trying to do everything possible to get myself in a position where I need to do the twisting slap hinge to get the ball to go up very powerfully when I need that. For example, if you want to jump up, you have to bend down first. The golf swing is more complicated, but think through what would be the optimum movements you could do to get the ball to go up and then you will understand better what I am doing.
Thanks,
Rock

Rock, interesting observations. While the second one in bold is easier to grasp -- flexion into extension as e.g. approaching the impact zone -- subconscious parametric acceleration, so to speak observed in many great swings, the first one relying on counteraction is more complex. If I understood you well, you sort of provoke the downswing action to happen by acting in a reverse manner during the backswing ?

Cheers, D.

Dariusz,
Yes, I am talking about reverse action in the backswing causing the action you want in transition causing the action that you want in the downswing through impact.

For example, the trail leg goes IR in the backswing which leads to ER in transition which is the reverse action leading to inertial through impact. We can go through that with every section of the body that reverse action leads to the action that you want in the next swing phase.

I have read about your Omne Trium Perfectum theory, and all of your theories as well, describing the three actions in the wrists and forearms (i.e. PF/UD wrists and Supination of the forearm) go together and we know we want that with the lead arm. The dialog I am advancing here is what is the reverse action that a golfer can do in transition and the backswing that would subconsciously lead to that which a golfer needs. The twisting push slap would be DF/RD wrists and Pronation of the lead forearm reverse action in transition of the golf swing leading to the PF/UD wrists and Supination of forearm action that you want through impact with the golf ball. If you concur with that explanation, then you have to make your way tracking these actions and reverse actions through the body down through the feet and into the ground and also outside the body into the golf club. Would be interested if the swing could be explained in these actions and reverse actions including the affect on the golf club which all of these actions and reverse actions are geared toward producing a result of the golf ball finishing at the intended target. I experiment with these reverse actions and actions or chain reactions throughout the body and its impact on the result. In this way, I came up with the idea of the twisting slap hinge. Any further insight that you can provide on the merits of this line of thinking and its application on other parts of the body. I have found it helpful to make incremental improvements in power and dispersion of the golf ball.

In summary at a high level, I am proposing a resolution to your assertion that a slap hinge CANNOT be accomplished subconsciously with a twisting slap hinge that CAN including a detailed explanation of how it is done.
Thanks,
Rock

Rock,
OK, I am with you. The example with rear leg IR and ER as the reverse action is very appealing and true. There is an important factor, however, to differ this from the hand/wrist/arm relationship overally. Namely the shear forces between the shoe sole and the ground and, therefore, pressures. There are no such forces acting in the upper limbs case which makes the whole thing tougher as we have to rely only on subconscious mind action without help of physics. Some help from anatomy is available -- achieving the physical limitations in joints though.
The Omne Trium Perfectum is not a theory, it is a fact and one of the most eviede3nd coupled (or in this case, tripled) motions. BTW, I am very big on this coupling motions in joints and a fan of looking for them in order to ease movements.
Finally, I understand your theory of achieving DF/RD/Pronation as the reverse action. Interestingly, it would be sort of opposite action of the famous Hogan's Life magazine secret when he dorsiflexed and pronated his lead forearm/wrist at transition and obtained UD/supinated one at impact.
The only theoretical objection I can have (before checking this in real motions) is that the classic slap-hinge action as Cotton wanted golfers to do is just DF/RD at and after contact and not approaching contact. Why ? Because it can lead to tops and hitting before the ball in case of weaker players.

Hope my points make sense to you.

Cheers, D.
