In some early posts I was asked about what core bracing is, In this video it explains why core bracing is so imporant and the key roll it plays in the golf swing.This is video is also describes how club head speed is most efficiently created by releasing or “flinging” the club rather than by the arms through impact zone. And how core brace is a key component in the process of releasing the club
Core Bracing and club release part1

This a question we had from some one it the US regarding Long Driving.
“Some long drivers report slightly higher swing speeds with slightly shorter drivers than the maximum 48” length. My instinct tells me that it has something to do with variances in muscles and joints from one person to another”?

This answer to this question is from founder CW.
In our experience the most likely reason, and we have seen this quite a bit (when we 3-D test for biomechanics), is that the slightly shorter club reduces the lever arm or moment enough to get more release or angular speed which improves distal end linear speed/club head speed. The trick here is that the shorter the club, the smaller the moment to overcome when released, but the shorter length at the same time the less distal end speed for the same angular speed. We have done a bunch of testing with long drive competitors including jason zuback looking at the fine line between club length – increased angular speed and maximum club head speed. Getting it right depends on understanding individual biomechancis, anatomy and physical ability.
In addition to matching club length (and other characteristics) long drive competitors should also work on release dynamics from both a biomechanical and physical perspective. We do a ton of high speed, core brace – club release exercises to help golfers get more release/angular speed through efficiency of movement. From a physical perspective, most think they need to get bigger, stronger faster in the gym to gain club head speed – gym work, no matter how functional and progressive yields minimal results by itself. If the golfer learns to coordinate acceleration better and then learns to core brace/stiffen to release the club, they will gain a tremendous amount of speed quickly, especially when combined with improved gym based physical attribute (strenght, mobility, speed).

G’day mate,

Sorry bit slow on the uptake. Mate, I can full vouch for this, I have used an LDA 50” driver (48.25” traditional) and I have always felt “wrong” swinging these things. It is such a long lever to be trying to release effectively. I can definitely say a number of my technical and biomechanical breakdowns have been caused via this.

At the end of the day mate, I see it as poor science. Yes an inch may produce 2mph of additional clubhead speed, but what are you losing in mechanical efficiency and I can tell you it is a ton harder to get the ball centred with good release angles. So what you pick up on the swings, you lose on the round about…

It is not a case of strength either, Jason Zuback is one insanely strong individual. I am not exactly weak either, I have squatted and deadlifted more than double my body weight in the past. This length though is an external force that no amount of strength seems to overcome.

The only guys I have seen successfully use such long drivers are guys who are generally well over the 6’3 to 6’5 range. Like in any sport there will always be a freakish talent that overcomes the general observations of the masses, but as a general rule, I definitely know my optimum length will be much shorter than I have used in the past. This training period I am starting short and working out slowly rather than racing to the longest and coming in.

The interesting thing I notice is that baseballers create massive impact forces, how long is a baseball bat? 34-35”? Makes sense to be dynamically powerful rather than trying to add external power.

AB,
Great post, Phsyical strength is very important although as we both know you need the coordination patterns or kinetic link to be able to utilise this power and strength gained in our golf swing at the point of impact.
Your 100% right is really to find optimal length is start at standard get your coordination right then add length in small incrimants until it effects the angular speed. You then find maximum length that you can handle with out effecting the power generation process.
In my next post below this video explain how angular speed is created and what core bracing is.

This is review about the X-factor, Chris Welch a biomedical engineer and leadinf research in biomechanics has come forward and explain the myth’s about X-factor this is an article he is referring to
X-Factor

In this review of x-factor online today at Golf Digest/Fitness Friday, I would have gone way further than Ben Shear and Craig Davies did and say that under no circumstance (regardless of playing ability and/or athletic ability) should anyone EVER try to MANUFACTURE x-factor or separation between the pelvis and thoracic during the BACK SWING. It serves absolutely no purpose. The amount of separation created during the back swing is not important, the dynamics of core muscular loading are important. The dynamics of core loading include rate of stretch, line of action, response and rate of shorten and these all happen dynamically during the downswing.

The manufacturing of separation or x-factor during the back swing only serves to do two things, neither of which are good.

1. put the body in a mechanically disadvantaged position – this negatively impacts the ability to change direction, sequence the kinetic link and puts the joints at higher risk of injury.

2. rob the muscles of the ability to create force by exceeding the natural optimal length tension ratio needed to shorten/contract in a ballistic way.

Also, just like the amount of separation during the back swing is not important to performance, its not the amount of separation during the back swing that can contribute to increased loads on the joints of the spine. It is more the fact that in order to manufacture separation the body relinquishes connection to the ground and muscular tension which is necessary to maintain stability. When the muscles “relax” in order to accommodate greater separation, the support structure surrounding the spine is compromised, the joints are less stable… when the body then changes direction in this manufactured relaxed state and applies a significant amount of muscular force through the core the joints are at higher risk for injury.

The thing to focus on is the initiation of the change of direction, NOT back swing separation. Separation and back swing “turn/rotation” will be dictated by your natural physical attributes including range of motion… if you change direction effectively and you will more effectively create power.

In the article referenced above on xfactor – author Ron Kaspriske states “It’s hard to argue that the torque created by restricting your hip turn while allowing your shoulders to turn as far as they can will help generate a lot of speed and power in your swing.”

The primary point of contention I have with this statement is that the body doesn’t coil up like a “big spring” in the back swing.

Let’s use examples that get away from golf swing to hit the point home – if you were trying to teach someone how to jump higher, how much time would you spend on how deep their pre-load squat was? if this was the case then guys who wanted to jump the highest would bounce their butts off their calves before jumping… I don’t see too many NBA athletes or Olympic high jumpers doing that, right? the physiology in the golf swing is no different.

Whether the lower body stays stationary or you allow it to rotate, whether the swing technique is stretched out and long or short and compact… it still boils down to the dynamics of the pre-load – shorten of the muscle or stretch-shorten. The amount of stretch becomes secondary is more a function of the dynamics and not manufactured separation.

That is a great post you have written above there Zen, bang on the money.

What a BS article…. My thoughts (as I have said before)

1. If X factoring was the definition of power EVERY female and junior golfer in the world would outdrive a male golfer. Females especially have a massive flexibility advantage over males, I am sure 90% could create bigger X factors than males. But they don’t hit it further, because muscular loading and contractile speed is the biggest contributor to power.

2. The shoulders are independant! They move independantly, they are not a unit. And the right shoulder will never move more than 30 degrees beyond the right hip.

3. Great first exercise recommendation, strengthen your EXTERNAL hip rotation and play sh*t golf for the rest of your life. Great players rotate internally into their hip joints, not externally to the hip joint. The second exercise has a high degree of awesomeness too, squat like that and you best be putting your name on the waiting list for hip and knee replacement surgury! How the hell do these guys get their positions as fitness gurus???

So not to spoil your thread mate, I will upload some videos to reiterate points 2 and 3 in AB Tees Off….

Zen is Brian ferguson at the sunshine range? I thought I might tale ur advice and go see him for a fitting.

DeepDivot,
Fergy at Sunshine and 3 days a week at MGA, Wednesday, Friday and Saturdays.

Thanks mate should I book in for club fit before or after mizzie demo day?

Hi Zen,

I sat on a table with Ian Triggs and John Senden as he is Johns coach and an absolute legend of golf training the other night at the PGA centenary dinner.

He told me he has been using Bio mechanics since the 80’s!!

Thought you might like to hear that!

Played with someone who tried to get me into the coiled spring. Having played a sport where muscle dynamic was paramount I found it uncomfortable and not easy to replicate accurately.

And not advisable on the backswing.

Don’t ever do today what u can put off till tomorrow.

I’d go before so you know what try out first.

Champions League you’re having a laugh…..

Jetset,
Ian Triggs is a wonderful coach and a true gentleman. I have so much time for Ian. I referred him on of my clients to him and Ian has done wonders for his game. I did some stuff with Ian, he’s pretty switched on guy.

That is a great post you have written above there Zen, bang on the money.

Regards to point two the shoulders aren’t really rotating sure they internal and externally rotate. Really our spine is rotating, the shoulders. The shoulders as a function rotate around the axis of the spine. In our spine we have facets and each facet recruits a small amount of rotation going up the spine from L5 up to T1. If you do the math maximum if you are hyper mobile is around 70 degrees the shoulder rotate.
What they haven’t factored in is connection with the ground and whether or not people are creating an internal hip rotation or external rotation.
If some one has an external rotation of the hip when measuring the rotation of shoulders is going to have more shoulder rotation when measured. This is why the number are so high, they aren’t measuring internal and external hip rotation.
From an anatomical point the hips can not internally rotate any more than 30 degrees.
I’m glad researchers are finally come out and speaking up about the X-factor myth.

Played with someone who tried to get me into the coiled spring. Having played a sport where muscle dynamic was paramount I found it uncomfortable and not easy to replicate accurately.

don’t like lies, young people using golf carts when they are fit, abusive posts.

Tom,
In most cases when people try to coil on their back swing in any sport swinging a club, bat or racquet what we have found is people start creating an external rotation of the lower body and loss good connection with the ground. This then puts the athlete in a mechanical disadvantage to commence the downs swing. They start either spinning their hips or sliding the hips or do both. This causes all sorts of other break downs in your movement patterns.
The short/ stretch cycle occurs in the downswing. It’s not about how much separation we create between the lower and upper body, it’s about how much torque we apply to the muscles being stretched. In golf it’s hip rotational speed. On the downswing the hips accelerate first, the higher the rotation speed the more torque applied to the muscle.( Hence all we need is 5 degrees on the rotation to achieve this). Whats crucial is as soon as the torque is applied by the hips, our hips need to decelerate straight away so the muscles can contract.
Why this is very important is when a muscles is stretched rapidly we create an elastic energy. (We call this the preload effect). This elastic energy make the muscle contract rapidly which increase the accelerating of the muscle which increase the speed of that body segment. The longer we keep a muscle stretch the more elastic energy we lose to contract and accelerate the muscle. This is why it’s crucial to decelerate the lower body.
I hope this makes sense it’s pretty hard to explain this stuff in simple terms in writing.

It makes sense to me – now!

Hi Iseek readers,
Of late been flat out around the globe, we have signed up another 3 top 100 coaches to use ZenoLink product/service. I’ve been busy get the new 3D gym going at tower hill on golf links rd just of the highway and finally finished, we are now in full operation.

Below is a video expalining the theoretical model of the kinetic link in how the human body facilitates and coordinates move, speed and power. Not only does this apply to golf also any other bat and ball sports. This is how the human body facilitates and coordinates movement. In this video I put forward the graph measuring a US tour player supporting the theoretical model using 3D biomechanics. To prove the theory was right they also used Force plate and EMG data which measures muscular activity.

Over the years our company has tested and worked wiht more female and male tours players than any one on the planet. It’s funny we are always banging our head against the wall trying to educate the golf industry, what is it with golf and why do people think the swing is some mystery. When it’s not at all. The club is connected to the human body and there is a certain way our body is structured to move and function anatomically. The golf swing has to move with in these confinements or golfers get injured and also can’t swing a golf club very well at all.
Anyway my turn to have a little rant LOL.

Hope you enjoy this video
Kinetic link theory and practical graphs match

Nice trophy PnB!!!

And yes Scott …....... I too appreciate your advice re course management …... its starting to pay off.

Hope all is going well for you at your new digs.

Hi GP,
We are slowing getting up and running, once I am, I’ll send an email in your direction to come and do a grand tour, Long Island Golf Club.
Glad the course management tips helped, I found a 3 wood that works for me now and pump about 230 including role.
The driver is staying in the bag around Kingsy no need for it.
I sort of played driver because I had no 3 wood and is a real low percentage club to use around there.
I got my data back as well, no wonder I was hitting it sides ways,I improved although my arm and club was out of sink with the upper body, surprised I keep it on the golf course at all.

Gp,
This is for you mate, everything is explained right handed.
This is a video analysis explaining the 3d data of the biomechanical breakdowns of a left handed golfer.
A big thank you to our client Jamie Heffernan who gave us consent to post his clients information to the public.
3D analysis video of a left handed golfer

Hi Scott, thanks for sharing the video analysis …. it’s nice to see a lefty going through his paces, and also, to have the charts explained once again.

I think seeing the video and charts combined like that, could only help for the “penny to drop” and it makes both aspects of the analysis much more relatable to each other. Some very good work going on there!!

As for your 3 wood …....... I reckon they are almost as hard to find as the right driver, and finding a decent one can be worth plenty to your golf game. (I’ve been through a few of them too)

No doubt you’ll be giving it quite a workout around Kingswood, as I figure the course was built “of an era” where drivers of the day ….... would go about as far as your modern day 3 wood. (It should also be good for keeping them on the short suff at Long Island)

I’ll look forward to taking the “grand tour” .... but for now, get back to doing your exercises buddy!!!
