Lexi Thompson Swing 2014 – Analysis of Joint Positions and Anatomy

Lexi Thompson Swing 2014 – Analysis of Joint Positions and Anatomy

Even the most talented professional golfers do not make ‘ideal’ swings in terms of how their joints can work best, simply because prior to this no-one has ever thought to consider that aspect.

So, an athlete such as Lexi Thompson can improve too, by positioning, at the top of her backswing, her entire spine (head to tail bone), right shoulder and right thigh closer to the positions of her impact, rather than diametrically opposite of what they are!

For instance, if she needs her spine to be tilted away from target at impact, it should be so at the top of the backswing. If her right shoulder is to be externally rotated at impact it should be so at the top. her right hip should not be so extended backwards at the top, as the ‘close-packed’ position requires some aggressive repositioning to get it into its desired downswing position.

Comments on the ANATOMY of this and that….

Had the honor of speaking with Dr Tom Boers, physiotherapist to the LPGA and PGA Tours. A wonderful quotable quote from him, “The golf swing should be designed around the spine, not the spine around the golf swing”. If only more people in golf understood that.

He has worked with very many injured golfers’ backs, including that of Suzann Pettersen. Scroll down to the previous post to see the video analysis of the anatomy of her swing and understand what might have exacerbated her disc irritation a few months ago. Also, a golfer’s standing posture is rarely analyzed in golf, look at hers below:

Then there is the question of swing efficiency. It seems to be very popular (and this is true for all skill-levels of golfers, all over the world) to make long back- and through-swings for small ‘chip’ shots. Did these originate from the ‘dog must wag the tail’ phrase, requiring shoulder involvement even for short shots such as chipping? Did it originate from people believing the wrists are essential for all shots [see the note at the end of this post regarding wrist involvement]? Whatever its antecedents, the ‘modern’ chip shot involves too many joints being bent/twisted during the backswing for there ever to be enough time to undo it all, in this tiniest of swings.

Look at this big dog. If he had a tiny fly sitting at the end of his tail, should he ‘wag’ his entire body to get rid of it? Would simply wagging his tail not be sufficient? That would be the equivalent to a chip shot being made with the arms acting as two sticks, with no in-swing knee bending, no hip rotation and no shoulder rotation. A simple pendulum-like motion (with a shallower arc than a true pendulum would have), picking the ball off the ground with no dramatic divots.

Look at the size of back- and down-swings of this golfer making a small shot from 15 yards off the green, with 5 yards of green to the pin, OFF an UPHILL LIE! Do not all professional golfers attend ‘Chipping 101’, the basic class that tells one not to have a big arc of swing from an uphill lie, as it reduces the margin within which they can err?

Screen shot 2014-06-20 at 8.11.58 AM

In the above situation, the golfer has to undo all of: 1. neck forward flexion 2. left arm adduction (the ideal lead-arm movement should be more like a flexion – post a question in the forum here if interested in how/why) 3. right shoulder elevation 4. right shoulder internal rotation 5. right wrist extension (backward bending) 6. left trunk lateral flexion

Another golfer made 6-7 practice shots from the same position with a highly lofted club which had lots of bounce, and brushed the grass at different spots each time, to get the feel of what to do. Better sense finally prevailed and she chose to go with her putter. However, even then she made a long swing arc back and through, with the putter-head moving steeply up then down and then up again. Both chip and pitch shots should have a low, shallow arc, especially on an uphill lie, to increase the margin within which to err!

As regards bunker shots. See this green-side bunker top-of-backswing and past-impact positions. At the top there has been wrist bend, right elbow bend, left trunk bend and a lot of spinal rotation – different at each of the spinal levels – the cervical or neck region has remained in place, and the thoracic spine (where the ribs are) has rotated. The lumbar and sacral areas (hip area) are probably being kept in place, if the amount of knee flexion is any indication (players are often told to have a ‘solid base’).

In the downswing she chokes –  as can be seen by her hands, which stop moving during early and late follow-through. Her brain probably makes hers arms decelerate in reaction to feeling either that there will be more-than-required acceleration from the body’s involvement OR that as her shoulders spin open, over-the-top, the club will come too close to the ball (not stay behind the ball as would be the case with an ‘inside’ approach). Another reason for the cessation of her hand and arm movement could be that her head turns during early follow-through.

The Minimalist Golf Swing System works not only for the full-swing, but has excellent heaven-sent solutions for the basic pitch, chip and putt strokes too. [An example of MGSS simplicity – create any steepness required for a slightly high chip shot or what might be termed a pitch-and-run shot, from elbow, NOT wrist, bend, as there is more time for the trail elbow to straighten than for the trail wrist to do so].

Suzann Pettersen

What a phenomenal athlete! Can just imagine how pure her ball striking could be with an anatomically efficient golf swing, where every joint is positioned according to its design-based capabilities.

See her golf swing assessed for where her body is during address, backswing and downswing. Also a picture which shows what could have caused/exacerbated, with overuse, her back injury of a few months ago.

The Common Factor in six MORE top Women’s Backswings

The Common Factor in six MORE top Women’s Backswings

Muscles of downswing rotation:

The abdominal obliques rotate the spine and the gluteal muscles (along with 6 other ‘ladder’ muscles) rotate the hips. They can rotate best when the spine is as upright as possible and rotate less and less efficiently as the spine and hips get more and more flexed forwards.

The consequences of no backswing hip rotation, along with steep trunk lateral flexion:

A lot of muscles have to hustle to position several joints into positions from which they can deliver the club to the ball from the inside. Women do not have as much fast-twitch muscle as men, and also have larger hip areas to rotate during the downswing, so will not always be able to time (ie sequence or co-ordinate) all movements in an efficient manner.

See six more top golfers with negligible to no hip rotation during the backswing, and too much trunk lateral flexion. All the various parts of the spine having to torque at different rates and in different directions! OUCH.

The Common Factor in six top Women’s Backswings

If you were asked, “What is the single most common swing position seen during the top of these backswings?’, what would your response be?

The answer is in the ‘backside’. NONE of theirs have rotated!

L to R: Stacy Lewis, Michelle Wie, Paula Creamer, Jessica Korda, Se Ri Pak, Lexi Thompson.

So now, power must come from only an unwinding trunk, when women have so much more in the hip and gluteal-muscle area.  A lot of women are then excessively torquing their spines, and so having to unwind lumbar, thoracic and cervical areas of the spine at different paces and times, as they all have different sizes and roles and the spine is not in position to unwind as a single column.

The result? In-efficiency of ball-striking, potential for injury.

The ENTIRE SPINE – from neck to tail-bone NEEDS to be rotated back as a single column!

Anatomy of the swings of some participants –

similar or different to what the male pros of last week were doing?

Anyone care to comment on these backswings – in terms of how many separate joints are being moved and potential consequences to both ball-striking efficiency and injury potential?

What seem to be the common factors?

Please post your comments here.

Anatomy of new Golf Swing Trends from US Open 2014, Pinehurst No. 2

Anatomy of new Golf Swing Trends from US Open 2014, Pinehurst No. 2

The new trends that all the pros seem to be following are:

1. Full swing: a big spine forward flexion and a steep lead shoulder tilt during backswing and an equally steep shoulder tilt during downswing.

The result? A huge, deep divot.(see Martin Kaymer below)

Screen shot 2014-06-14 at 6.11.02 PM

Screen shot 2014-06-15 at 2.46.17 PM

Effect of ball-striking efficiency – with such a deep divot, a lot of the intended power goes into the ground – a simple vector summation of forces drawing will show that. Its great when the players are young and supremely athletic and they have so much force production to spare that they do not even realize that they could get much more distance with a shallower divot.

However, the main problem is direction. The ‘upright pendulum’ which seems to be the latest version of the golf swing,  means that there is a very narrow margin within which direction can be good. Also, as the club rides inside such a deep divot, it could be prone to being twisted in the hands, as it digs through a large quantity of our planet!

All this excessive effort for not enough result probably comes from the new concept of making a squat-jump type move during the downswing to enhance ground-reaction-force (GRF). As the lead upper body ‘jumps up’, it apparently allows the golfer to decelerate correctly. No-one, however, has quantified how much ‘jumping-up’ to create GRF is optimal. The Minimalist Golf Swing creates ‘just enough’ GRF, by not requiring any up-and-down motion, but simply from the natural straightening of the trail arm! Does the full-swing need, and can it afford, all this excessive movement?

2. Chipping: What a big back-and-through motion (see Rory McIlroy below). Why are chip shots involving so much shoulder rock, ever since some famous pro told the world ‘The dog must wag the tail”. All it needs is an arms back-and-through movement, a much lower clubhead trajectory in both directions, and a ball which has the bare minimum air-time for it to just carry the lip of the green, then roll, like a putt (the simplest, least error-prone stroke) the rest of the way home. With a lower trajectory, the extra joint-movements of the shoulders gets reduced, and intentional shoulder-movement is a much more complex movement than that of just the arms.

Does the chip shot need, and can it afford, all this excessive movement? [And, on that subject, did Martin Kaymer win because he always used his putter from off the green, making a much simpler stroke?]

Screen shot 2014-06-15 at 2.42.58 PM

3. Putting: Open shoulders and a right (trail)-arm-back-and-through movement (see Martin Kaymer below). This makes both elbows bend to differing amounts during back-and-through swings and differing amounts of shoulder rotation too, resulting in inconsistency. Does the putting stroke need, and can it afford, all this movement?

Screen shot 2014-06-15 at 2.43.50 PM

Consider the human joints, folks, they are sadly (so far) not designed to move in all directions with equal ease, and require everything that’s done to them during the backswing to be un-done – in correct sequence – in the fraction of a second that the downswing lasts!

Review – Tom Watson’s Lessons of a Lifetime – an Anatomical Perspective

A review of Tom Watson’s newly released ‘Lessons of a Lifetime’ DVD series.

See the new section ‘reviews’ in this blog to read all about these 3 DVDs. You’ll see the collective wisdom of the best players and teachers of the 70s, 80s and 90s.

Also discussed is how some of the instruction imparted is quite scientific, while some is not, especially from an anatomical perspective.

Why does science matter? Why does anatomy matter?

The answer to the first question is that this IS the 21st Century – why should we settle for subjective, when advances in research have made it possible to be extremely objective about everything we do during the golf swing? When every other sport is basing their movements more and more on what research says?

The answer to the second is that no matter whether we’re old or young, large or small, male or female, we all have the same skeletal structure, the same muscles and ligaments and joints and they are not capable, as we often believe them to be, of movement in any old direction – regardless of how flexible and strong our muscles are!
