5 Reasons Why Self-Directed Golf Fitness Programs Fall Short

Today’s post was taken from the Titleist Performance Institute website.  It was written by Ryan Blackburn, owner of Orlando Golf Performance and TPI certified fitness professional.  I am not going to comment on it that much, but it is interesting to note that 3 out of the 5 reasons that he gives is directly related to the assessment process and individualization of programming.  To put it simply, it matters.  I have not had the opportunity to meet Ryan, but I think he hit the nail on the head with this one.

What Common Physical Characteristics Do Low Handicap Golfers Have?

As presented —> HERE, highly proficient golfers tend to have greater club head speed and increased driving distance.  This is such a desirable goal that researchers looked at how performance in specific low tech tests correlate to club head speed.  As expected, more power in the legs, arms, and trunk equals more CHS and driving distance.  I wrote an entire post on that topic —> HERE.  However, until somewhat recently no research has examined physical performance characteristics and their relationship with handicap differences.

In 2007, Sell et al. examined whether strength, flexibility, and balance in specific areas of the body are common in different groups of handicap. The authors believed that understanding these trends and improving them would facilitate the design of a golf specific strength and conditioning program, and that lower handicap golfers (<0-9 handicap) would have better strength, balance, and flexibility scores overall than higher handicap golfers (10-20).

They evaluated over 250 golfers that were split into 3 groups, <0 handicap, 1-9 handicap, 10-20 handicap, and were put through common strength, flexibility, and balance testing.  Their findings were not shocking, but very interesting in that scientific research is suggesting what we probably should have known all along.

Strength Results

The authors found that “core” strength, especially around the hips, pelvis, and low back is essential to performance in golf because an effective swing requires the golfer to maintain a stable lower body while rotating the torso, upper extremities and head. The faster the torso rotates the greater the strength of the lower quarter needs to be, and golfers with a lower handicap had consistently greater lower body and core strength than the high handicappers. Interestingly, the authors also found low handicappers to have greater shoulder strength (especially in the rotator cuff).  This is important not only in the delivery of the club head, but also in the prevention of injuries.  Check out an article on shoulder injuries in golf —> HERE.

Stable lower body, mobile trunk, stable shoulders....I feel like a broken record.
Stable lower body, mobile trunk, stable shoulders….I feel like a broken record.

Flexibility Results

Range of motion and mobility is obviously important in the golf swing.  The authors discovered that the shoulders, hips, and torso are consistently more flexible in lower handicap golfers.  Specifically, right shoulder external rotation (think back swing), right shoulder extension, left shoulder flexion and abduction (again think backswing).

This is why we perform the Shoulder 90/90 Test —> HERE, and the Lat Test —> HERE.

As for the hips, the most notable was right hip extension (which makes sense because optimal glute function is achieved if you can get into extension), and left hip extension.

This is one reason for why we perform the Bridge with Leg Extension Test —> HERE.

Right torso rotation range of motion was higher in golfers with lower handicaps.

This is a great reason to get screened specifically by the Torso Rotation Test —> HERE, as well as the Seated Trunk Rotation Test —> HERE.

Balance Results

Interestingly, the only difference here is that the golfer’s with better handicaps performed better on the Single Leg Stance Test on their right leg.  There was no statistically different findings on their left leg.  However, other studies have shown otherwise.  In my opinion, it is important to achieve good balance during single leg stance especially due to the fact that the golf swing requires a large weight shift to the right leg on the back swing and left leg for the down swing (for a right handed golfer), as well as occasional requirements to hit from an uneven lie (downhill/uphill/ bunker/ awkward stance/ etc.).  Remember, the average PGA TOUR professional can maintain single leg stance with their eyes closed for 16 seconds.

Hopefully you enjoyed this post and are beginning to realize that major differences in performance are of physical qualities, not just skills.  Just like the difference between NBA players and college players are attributes like speed, ability to jump higher, stronger, bigger, more endurance, more coordination; golf is no different.

The Team Approach to Golf Training

The team approach is something that is at the forefront of healthcare in the United States.  Even in physical therapy school we were encouraged to co-treat with other members of the healthcare team such as nurses, physicians, pharmacists, social workers, etc.  This, in theory, should maximize patient care by employing what I refer to as “division of labor”.  Every member of the healthcare team has a specialty, and should the patient need that specific division of service, the outcomes will be improved. Everyone is happy. Everyone wins.

This same model is the hallmark of the Titleist Performance Institute and is a new wave, cutting edge approach to golf training. No matter how high or low the handicap, I believe that this approach should be part of every golfer’s training regimen.

Before I discuss the modern team approach and what it means for the potential improvement of every golfer, let’s discuss “the old approach” of the 1990’s.  As described by TPI, the PGA of America would teach their instructors that the best way to fully serve their golfer was to have them consult with three professionals:

  1. The Golf Coach/ Instructor
  2. The Sports Psychologist/ Psychiatrist
  3. The Golf Club Manufacturer

Then, in 1996 something happened that would change the game as we know it.  Perhaps a more appropriate phrase is that someone happened.

Love him or hate him, he changed the game.
Love him or hate him, he changed the game.

Tiger’s game was different than anyone had seen before.  Power, strength, flexibility, and a chip on his shoulder.  These attributes began to affect the way competitors were preparing for the game,  and with that, the “team” became larger.  The newest addition was what was termed “physical conditioning” and included improving aspects of the body that influence performance.

The Modern Approach

The Modern Approach to the team has all of the members that were included in the old approach including golf coach, club manufacturer, and sports psych.  Now, several new members are on every tour pro’s team including business manager, strength and conditioning coach, and the medical professional (usually a physio).  This post will detail three of members of the modern team and how the communication between these three professionals can improve the performance of the golfer.  It is also important for each member to understand the “division of labor” and know when to consult another team member.  The three team members that will be detailed include:

  1. The Golf Coach/ Swing Instructor
  2. The Medical Professional (Physiotherapist/ Physical Therapist)
  3. The Fitness Professional (Strength and Conditioning Coach)

The Team

  1. The Golf Coach/ Swing Instructor
    1. It goes without saying how important the swing instructor/ golf coach is to the golfer.  Understanding the swing and implementing drills and exercises with the use of modern technology to optimize the player’s grip, stance, backswing, downswing, spin, launch angle, etc. is paramount.  However, I would like to propose something that many golf instructors may not consider. I believe that optimizing movement (improving flexibility, strength, balance, and other physical characteristics) so that the golfer is capable of performing the tasks that are instructed by the coach and to have durability to endure hours of practice will allow the player to rapidly improve their game.  Likewise, a coach should know if there is a significant flexibility limitation or previous injury so that they can appropriately coach and put the golfer in a position to succeed.  This, in a way, is building a swing around the golfer, not trying to make every golfer perform the “ideal swing”.  These reasons, among others, are why the golf coach should build a team around themselves and their student.
      1. Maybe his swing truly is "ideal."  But, perhaps his flexibility and balance is as well!
        Maybe his swing truly is “flawless.” But, his ideal flexibility, power and balance allow him to have that swing!
  2. The Medical Professional 
    1. The final two are what has adapted from the original “physical conditioning” team member in the 1990’s.  The medical professional obviously would lead the way when the athlete is in pain or recovering from injury. However, they also should take the lead in regards to the functional movement assessment.  The physiotherapist (physical therapist) can offer something that no other team member can – manual therapy and therapeutic exercises.  If the golfer is in pain or needs to correct muscle imbalances that are effecting his/her strength or flexibility, the physical therapist can use specific manual techniques to alleviate the dysfunction.  I may be biased, but PT’s are experts in evaluating and treating human movement, and understand where stretching or strengthening can be added to optimize movements specific to the golf swing.  This can be done with the Selective Functional Movement Assessment – a systematic approach to assess fundamental movement patterns to isolate the specific area of the body causing the limitation.  That does not mean that they should write strength and conditioning programs for the golfer.  That is the job of the fitness professional.  But, if the athlete does not have the competency to perform movements related to golf or training, the physio should be consulted.  There is a second key job of the medical professional.  As stated previously, the best coaches understand their athlete’s strengths and weaknesses and build unique to them.  So, another innovative model by TPI is that the medical professional can assess the golfer using the TPI Golf Specific Screen, then consult with the golf coach to allow them to know where their main deficits reside.  This will allow the coach to understand positions and movements that the golfer will have difficulty performing at that time.
  3. The Fitness Professional
    1. Once the athlete has the competency required to partake in a strength and conditioning program (no pain, no major ROM restriction), the fitness professional will evaluate the golfer and implement a physical conditioning program. Strength, balance, flexibility, power, and endurance are all important characteristics for golf performance and injury prevention, and the fitness professional is the best team member for the job.  With the expert knowledge of performance, strength and conditioning and programming to optimize human movement, the strength and conditioning coach is of utmost importance in the training of a golfer.
    2. Don’t just take my word for it, check out this quote from Brad Faxon in an interview with The Wall Street Journal, “A lot of the old guard still blame equipment for the increased distance on Tour, but so much more of it is the quality of the athletes,” Mr. Faxon said. “You don’t have to work out to play on Tour, but if you don’t, you get passed, because you’re not strong enough. And the stuff we do these days is all full-body, functional movement.” The entire article can be found —> HERE.  I encourage you to read it as it piggy-backs this post.

There is not one member of the team that is more important.  They all work in unison to maximize potential by correcting flaws that limit a player’s swing, and improving performance and durability to keep the athlete healthy and strong.

So, if you want yourself, your son/daughter, or your student to reach their full potential in the game of golf, I believe that surrounding him/her with a great team can help to streamline their success.

The Need for Speed (and how to test for it)

Golf performance has become more mainstream with technological advancements and cutting edge research by golf performance companies such as, The Titleist Performance Institute (TPI).  Knowledge of fitness, performance, and technique is essential to anyone in golf who is looking to get an “edge” on their competition.

At the forefront of golf coaching, performance, and rehab!
At the forefront of golf instruction, performance training, and rehab!

As stated earlier —> HERE, it is well established that club head speed (CHS) is a golf specific objective measure that correlates directly with driving distance, lower handicaps, and the enhancement of overall golf performance (Fradkin et al., 2004).

Previously, high tech tests were the only way to test for club head speed.  However, this is very difficult to the majority of golfers because of the requirement for expensive equipment.  Recently, field-based tests have been found to reliably measure golf specific power and correlate to club head speed.

There are several ways to test for power and human performance, but which tests correlate directly to golf and increased club head speed?  The three tests most commonly cited in research are listed below.

And, to the golfer!  That is, if you want lower scores...
And, to the golfer! That is, if you want lower scores…

FIELD-BASED TESTS

  1. Vertical Jump: The vertical jump tests for lower body power.  There are many ways to test for vertical jump, but many of them require extra equipment.  The least expensive and least involved way to test for vertical jump requires only a tape measure, a wall, and chalk.
    1. To perform, the subject marks his/her finger tips with chalk.  Then, they will stand as close to the wall and reach one arm as high on the wall as possible in order to make a chalk mark.  After this mark is established, the subject will then assume an athletic position near the wall and jump as high as possible touching the wall in order to make a second chalk mark.  The distance between the two chalk marks are considered the vertical jump height – measured in inches.  The best of 3 trials is recorded.
      1. Here is a youtube video describing how to perform the test.  Click —> HERE.
      2. The average PGA TOUR professional scores between 18-21 inch vertical jump.
  2. Seated Medicine Ball Chest Pass: This test measures upper body power. This test only requires a few items including a chair (with a back), a medicine ball (4kg for men, 2kg for women and juniors), and a tape measure.
    1. To perform, the subject sits in the chair with their back touching the seat back.  Without losing contact, the subject performs a chest pass and launches the ball as far as possible using his/ her upper body and chest.  The best of 3 trials is recorded.
      1. The average PGA TOUR professional scores between 18-20 feet.
  3. Supine Medicine Ball Sit-Up and Throw: This tests measures core power.  More specifically, it tests the ability of the athlete’s core to transfer force through their upper body to propel an object.  Does that sound familiar?  It should, because that is what the core does in the golf swing! All you need here is a medicine ball (same weight as above) and a tape measure.
    1. To perform, the athlete starts supine (lying on their back), brings the medicine ball overhead and as they sit up launches the ball as far as possible.
      1. The average PGA TOUR professional scores between 18-20 feet.

KEY POINTS

  1. Club head speed is important in terms of golf specific power.  Increasing your club head speed can help to lower handicaps and improve your game.
  2. Power can be trained in the gym by using strength and plyometric exercises.  Find a golf fitness instructor or physio to get you on track and individualize your program!
  3. Field-based tests have been examined and found to correlate to club head speed.  Each of the three test upper body, lower body, and core power.
  4. All three are equally important, so if there is a major imbalance in an area, attempt to improve that score to “balance” the three instead of increasing an already adequate number and creating a larger imbalance.
    1. For example, if a golfer scores the following: 15 inch vertical jump, 19 foot chest pass, and 20 foot sit-up/throw, then a program that focuses on lower body strength, stability and power would be warranted.  A program that has an upper body and core focus would further the imbalance.
  5. Attached is a video from TPI explaining each of the tests in further detail.  To view it click —> HERE.

Elbow, Wrist and Hand Injuries in Golf

elbow pain

As previously presented HERE, injuries of the elbow, wrist, and hand are second most common of all injuries sustained by golfers.  Not surprisingly, these injuries are more common in amateurs versus professional golfers.  The flexor and extensor tendons (muscles in the front and back of forearm) of the elbow are particularly susceptible to injury due to the repetitive demands of the golf swing, and the requirement of those muscles to be active during impact with the ball and the ground.

Two main elbow injuries are seen in golfers, medial epicondylitis (Golfer’s Elbow) and lateral epicondylitis (Tennis Elbow).  Interestingly, tennis elbow is as much as five times more common in amateurs than golfer’s elbow! These injuries are most often caused by repetitive use or a single traumatic event like hitting a “fat shot.”  As stated HERE, overuse injuries are usually seen in professionals and competitive golfers because of large practice times, and amateurs usually suffer from trauma especially with improper form or a bad swing.  It is no surprise that the incidence of elbow injuries increase with an increase in rounds of golf per week (especially if its 2 or more rounds per week).

Currently, limited to no research relates physical qualities of the golfer to factors that predispose them to elbow injuries.  However, as with most situations it is important to have full range of motion and strength.  Normal flexibility and sufficient strength typically allows our bodies to be more resilient especially when repetitive stresses are being applied to the same area.  This is analogous to runners having a strong lower body and core as well as mobile hips to attenuate the ground reaction forces being applied from the ground during each stride.

With that said, below are three quick tests that you can use in order to determine whether you have enough wrist range of motion.  Again, this is not exhaustive, so even if you pass these tests but have some wrist/ forearm or hand pain you should be evaluated by a medical professional.

RANGE OF MOTION

  • Wrist Extension: Click the link —> HERE to perform the screen.
  • Forearm Rotation: Click the link —> HERE to perform the screen.

MUSCLE STRENGTH/STABILITY

It is not within the scope of this post to discuss strength and stability tests of the forearm that would be used in a clinical examination.  Furthermore, there is limited research as to the efficacy behind what is “sufficient strength” and whether or not it reduces the risk of injury.  However, there is some current research that relates decreased shoulder strength/ endurance in individuals with tennis elbow.  View the full abstract —> HERE.

Also, a quick golf specific screen to consider shoulder impairments can be viewed —> HERE.

Again, prevalence and mechanism of upper extremity injuries in golf is relatively well understood; however, there is limited research as to predisposing factors for injury and injury prevention other than improvements in technique in the golf swing.  Hopefully, more research will be performed in the near future.

 

 

 

Golf Injuries: An Overview

golf injuries

The following is an overview of golf injuries including how, why, and who they occur to including comparisons between professional, amateur and the aging golfer.  Furthermore, a brief discussion on risk factors, swing considerations, and injury prevention strategies will be presented.  More detail of each will be presented in future articles, but this general overview serves to develop a background knowledge base for the athlete, parent, coach, fitness and medical professional.  It is quite long, so sit back, grab and Arnold Palmer and hopefully it will expand your knowledge base about injuries in golf.

Introduction

Over the last decade, an increase in the popularity of golf has been well documented.  An estimated 55 million people worldwide participate in the great game of golf!  With that, the number of courses in the USA, Europe, and Asia has increased tremendously.  With this increased accessibility and participation (among other things), an increase in injuries has also occurred.  Golf is usually described as a game that requires mild to moderate activity level; however, injuries in golf should not be underestimated or undervalued.  Additionally, many mechanisms and characteristics of injuries appear to be consistent with different skill and age groups who participate in the game.  Having an understanding of these consistent occurrences should facilitate the decision making process on developing strategies for prevention, rehabilitation, and enhancement of golf performance.

Golf Injuries in General

In general, golf injuries originate from either over-use or from a single traumatic event, and primarily affect the low back and upper extremity.  Amateur golfers have an annual prevalence of between 25.2-62% (1.19-1.3 per golfer per year), and the main risk factors appear to be low handicap and age over 50 years old.  On the other hand, in the professional golfer, it is closer to 88% or 2.0 injuries per golfer per year.  The higher prevalence in pro golfers is likely due to the increase practice times and repetitive nature of the game.

There are slight differences in regards to body parts affected, but in general the most common sites for injury are: Low Back (28-35%), Elbow (25-30%), Hand/ Wrist (15%), Shoulder (10%) followed by the lower extremity equally (hip, knee, ankle).

Who is at Risk for Golf Injuries?

Two primary groups of golfers are at risk for injuries: amateur golfers comprising of recreational and occasional, as well as professional golfers.  Occasional golfers are documented to be prone to injuries related to a poor knowledge of execution of golfing skills, resulting in traumatic injuries (usually at impact) or injuries related to badly executed golf swings.  In addition, amateurs in general are prone to overuse injuries due to various behaviors such as lack of warm-up, reduced mobility/ flexibility, limited strength, lack of physical conditioning, etc.

Competitive golfers (professionals and highly skilled amateurs) usually report soft tissue and musculoskeletal injuries associate with overuse.  This is usually due to the repetitive nature of the golf swing with intense or long practice sessions that cause imbalances in strength and range of motion predisposing these players to overuse syndromes.

Additionally, older golfers are considered “higher than normal risk” for injuries not only due to the nature of the game but also physiological factors associated with aging.

Injuries by Anatomical Location

Low Back and Trunk: As stated previously, the most commonly injured area is the low back.  However, reduction in participation was no more than one month for any episode of low back pain, and the most common injuries were minor which resulted in only one week of practice lost. Furthermore, the number of golfers with a history of LBP may be as high as 55% but it is unclear as to whether it is due to golf practice alone. Author’s note: This is consistent with orthopedic research regarding low back pain, which is said to be self limiting and resolving on its own in the majority of cases in 4-6 weeks.  Interestingly, the area of the body that has the largest practice time lost due to injury is the thoracic spine and not the lumbar spine.

Upper Extremity: Elbow injuries are the second most common, and moreso in amateur golfers than professional.  Medial epicondylitis (Golfer’s Elbow) occurs most in the right arm (for right handed golfers) usually due to repetitive resisted forces or from a single traumatic event like striking the ground and taking too large of a divot.  Lateral epicondylitis (Tennis Elbow) also affects amateurs more than pros, and occurs in the leading elbow.  The incidence of both conditions increases when the frequency of golf is increased (i.e. >2-3 rounds per week).  Interestingly, in amateurs Tennis Elbow is more prevalent than Golfers elbow!

Shoulder injuries are the third most common across the board, and most often related to overuse injuries due to excessive shoulder rotation at the top of the back swing and in the follow through.  In all reports, the leading shoulder was more commonly injured resulting in AC joint problems, impingement, rotator cuff tendonitis/ tears, instability, or arthritis.  Finally, wrist and hand injuries occur especially during forceful swings with high impact on the ground.

Lower Extremity: Lower limb injuries are no very prevalent in golfers, but it should be noted that the literature on the occurrence and mechanisms is limited.

Injury Distribution by Age

The average age for occasional golfers in the USA is 45 years old and one third of all American golfers are 50 years of age or older.  Not surprisingly, golfers 50-65 years old have the highest injury prevalence.  The reason for this is due to physiological changes that occur with aging such as changed in the musculoskeletal, cardiovascular, and neural systems.  Decline in strength, flexibility, coordination, bone and tendon resiliency and ability to deal with stress may increase rate of injury.  Author’s Note: This is another area of importance for the benefit of exercise in golf, but it is not the scope of this review and will be discussed later.  However, it should be noted that many of these declines in the aging adult can be mitigated with consistent resistance training due to the fact that type II muscle fiber (fast twitch) declines with age.  It is well documented that reduction of power and strength occur with normal aging, and with that a reduction in club head speed (golf’s demonstration of power) occurs between ages 40-59.

Mechanisms of Golf Injury

In amateurs that play an average of 2 rounds per week were most often injured by overuse, striking the ground with the club (hitting it “fat”), and poor swing mechanics.  Over-swinging, poor or incomplete warm-up, twisting of the trunk during the swing, and gripping too tight are other potential causes.  In professionals, overuse accounts for 80%, hitting it fat was 12%, and twisting of the trunk was 5%.  Professional golfers have almost negligable injuries due to poor swing mechanics, over-swinging, poor warm-up, or grip/swing changes.

Injury Versus Handicap

As mentioned several times, there are differences between professional and amateur golfers.  Professionals partake in regular competition and follow intense organized schedules of practice.  However, they are also usually engaged in carefully structured conditioning programs, and have better strength and flexibility indicators than recreational golfers.  Authors note: It is well documented that skill and fitness enhancement can reduce the risk of injury in other sports, why is it so hard to believe that golf would be any different? Spoiler alert…there is no difference!

Okay back the the details.  This next sentence is music to my ears!  Many problems detected in the amateur player  would probably disappear if a new and improved technique were adopted.  At the peak of the backswing, pro players were shown to exhibit significantly higher left shoulder horizontal adduction and right shoulder external rotation.  Professionals also have more trunk rotation at the height of the backswing and at the moment of ball contact.  How can you tell if you have enough trunk rotation? Click —> HERE.

Furthermore, low-handicap golfers who suffer LBP tend to demonstrate reduced erector spinae activity at the top of the backswing and impact, yet greater external oblique activity throughout the swing.  These findings are consistent with the “reverse spine angle” and “inverted-C” patterns.  More detail on these patterns are discussed —> HERE.  To piggy-back this idea, it is thought that this increased side-bending and early lumbar extension is a compensation from limited trunk rotation and frequently observed in recreational players.

Overall, low handicap golfers are injured more frequently than high handicappers, but the mechanisms and types of injuries are different.

Swing Phases and the Incidence of Injuries

With the understanding of how high club head velocities need to be reached in a short amount of time, it is easy to see that high stresses are applied to the body which can cause overuse or traumatic injuries.  Most articles separate the swing into several phases: (1) Ball Address, (2) Back-swing, (3) Down-swing, (4) Impact, (5) Follow-through.

Note the extreme ranges needed in the hips, shoulders and trunk!
Note the extreme ranges needed in the hips, shoulders and trunk!

With that said, most injuries occur at the end of the down-swing (18%) and follow-through (42%).  Many authors credit this to the high forces when the club is contacted with the ground and place emphasis on forearm muscle strength to maintain control of the club.  However, injuries may occur in any phase of the swing.

(1) Ball Address and (2) Back-swing: Ball address is characterized by adopting an optimal pre-stroke posture which may be different for some golfers but is generally an athletic stance with a neutral spine (flat back).  This posture will allow the golfer to generate maximal potential energy.  Structures may be stressed due to compromised starting position including: excessive loading of the spine through hyper-extension.  During the back-swing, shoulder injuries can occur through compression of the rotator cuff or sub-acromial bursa, or from instability of the lead shoulder.  Likewise, over-rotation of the trunk during the back-swing can cause injury.

(3) Down-swing and (4) Impact: It has already been established what forces occur during impact and the effects on the wrist/hand/elbow, yet the downswing has not been discussed.  Injuries during the downswing (and even impact) occur in the range of movement of greatest muscle activity.  Players who are less skilled have up to 50% less trunk rotational capacity than younger more skilled players.  This means that to compensate and be able to hit the ball as far, a higher muscle activity will be demonstrated.  Thus, higher loading of the spine is a result due to reduction in flexibility, strength and stabilization of the trunk/ spine.  This is another important reason for optimizing mobility and stability (i.e. strength and conditioning).

(5) Follow-through: During the follow through there is a rotary motion of the hip and shoulders so that the body faces the target.  With this, the lumbar spine is at risk for injury if the deceleration stops too briskly or if the final motion is too pronounced (ex. reversed “C” or over rotation).  To minimize excessive spinal load the spine should be vertical at the end of the follow through.

As for the shoulder musculature and rotator cuff in particular, the supraspinatus and infraspinatus of the lead arm are activated primarily during follow through, while the subscapularis remains active during the forward swing and ball impact.  Thus, these muscles are not only important for stabilizing the shoulders during the swing, but also during the follow through.

Summary

  • The general nature of the golf swing and subsequent injuries is quite similar among golfers.
  • Recreational golfers are more likely to suffer traumatic injuries from bad technique, insufficient warm-up and poor physical fitness.
  • Competitive and professionals are usually affected by overuse injuries which stem from strength and range of motion imbalances.
  • Low back pain is the most common complaint but its not clear if it is related to golf practice.  Find out more here.
  • Shoulder problems are also common, with the lead shoulder being more often reported.
  • Elbow injuries are second most common, with tennis elbow being more prevalent than golfer’s elbow.
  • Traumatic and impact injuries are more common in young or old players, and players with low skill levels.

Shoulder Injuries in Golf

golf-shoulder-pain

Shoulder pain and injury is consistently cited as the third most common injury among golfers.  This statistic has lead many researchers to conduct studies and formulate correlations between shoulder injuries, physical characteristics of the golfer and swing faults. Furthermore, it is not within the scope of this post to review the anatomy and pathophysiology behind different medical diagnoses (ex. rotator cuff tear, sub-acromial impingement, etc.) in regards to shoulder pain.  However, it has been well documented that treatment should not performed with only the medical diagnosis in mind and that each individual should be evaluated. The following is a summary of different mechanisms that have been found to contribute to shoulder pain in golfers.

RANGE OF MOTION

  • Shoulder Elevation: Optimal shoulder elevation is 170-180 degrees.
    • Many compensations will be viewed if this is less than optimal.  A basic screen is —> HERE.
    • Note: Do not let the name of the screen fool you.  If you are find a deficit in this test, it does not always because of tight lats.
  • Shoulder Horizontal Adduction: Optimal shoulder horizontal adduction is 135 degrees.
    • A good demonstration of horizontal adduction is located —> HERE.  The elbow of the moving arm (left arm of the subject in the video) should be able to at least cross midline.  However, be aware of hyper-mobility and its implications with instability.
  • Shoulder External Rotation: Optimal shoulder external rotation is 90 degrees.
    • Here is a great golf specific screen for shoulder rotation —> HERE.
  • Trunk Rotation: Optimal trunk rotation is 50 degrees in each direction.  It is necessary to understand that optimal trunk mobility is important in shoulder health because of the intimate relationship between the trunk and the shoulder blade.
    • Want to test your own trunk rotation? Click —> HERE.

MUSCLE STRENGTH/ACTIVATION

No isolated tests have been researched that correlate to reduction of shoulder injuries in golf.  However, understanding muscle activity during the golf swing can serve as a basis for training and improvement of the swing mechanics, so that selective strengthening and rehabilitation of shoulder musculature can take place.  This is important not only to optimize function and protection of the joints, but to reduce imbalances from the repetitive nature of the golf swing.

  • Rotator Cuff Muscles: FYI, several clinical studies have found that there is no difference in the activation of these muscles in men and women.  This is most likely due to the consistent nature and demands of the golf swing.
    • Supraspinatus and Infraspinatus of the Lead Shoulder: demonstrate low activity during the swing with peak activity occurring at take away and follow-through.  These muscles act as abductors and external rotators to help stabilize the shoulder joint.
    • Subscapularis: The most active of the rotator cuff muscles showing activity during most of the swing especially during the acceleration phase of the down-swing.

  • Scapular Stabilizers: These muscles are also very important in the health of the shoulder in golfers.
    • Latissimus Dorsi and Pectoralis Major: Most active of all shoulder muscles, with the lat acting maximally in the down swing and acceleration phase.
    • Deltoid: Interestingly non-active except for the anterior deltoid during the follow through to help with shoulder flexion.
    • Trapezius: helped to retract the lead shoulder during the down-swing and acceleration phases, whereas it was active in the trailing arm during the back-swing.
    • Rhomboid and Levator Scapulae: were active for retraction during the backswing and control of protracting during the down swing (especially on the right).
    • Serratus Anterior: acted as a scapular protractor and demonstrated peak activity during the downswing and follow through phases of the trailing arm.  In the lead arm, it demonstrated low synchronized activity throughout the swing which may explain why it is susceptible to fatigue in some golfers.

The lead shoulder (left shoulder in right handed golfer) has been found to be injured 3x more than the trail shoulder, and more recently, it has been reported that more than 90% of shoulder problems in golfers occur on the lead side.  During the backswing, the lead shoulder undergoes internal rotation, flexion, and horizontal adduction which can exacerbate certain types of conditions.  Conversely, during the down swing it undergoes abduction and external rotation.  A thorough history, clinical evaluation and symptom response are of utmost importance for isolating the shoulder dysfunction that is causing pain.  However, in simple terms it is important to optimize mobility/ flexibility and stability/ strength to protect the shoulder and torso against such high demands of motion and force.

As discussed —> HERE, low back pain and range of motion deficits (especially on one side) correlate to improper function during the golf swing.  Similarly, shoulder range of motion and strength deficits may be found on one side of the body versus the other.  This is due to the repetitive one sided nature of the golf swing.  Furthermore, the above information (especially in terms of range of motion) would be optimal on both sides of the body; however, emphasis should be placed on one side versus the other depending on the handedness of the golfer.  Likewise, an understanding of the above information can facilitate the evaluation of muscle imbalances in golfers which may lead to decreased performance and even injuries.
