What is a golf fitness assessment?

We’ve all spent countless hours hacking away on the range looking for a quick fix or band-aid. But for some golfers — and maybe most of them — it’s not their swing that’s holding them back, but their physical limitations.

That’s where fitness assessments come in to play. It tells golfers what they can be doing from a fitness perspective to rid their swing of nasty habits, and it can prevent injuries as well.

How an assessment works

A golf fitness assessment — such as those administered by TPI, an institute created by Dr. Greg Rose and Dave Phillips — is a screening that is based on golf biomechanics and fitness.

A compilation of normative data was created by testing a wide group of PGA and LPGA professionals and measuring their physical capabilities as they relate to the golf swing. The assessment will identify asymmetries, limitations and dysfunctional movement patterns — basically how good or bad you are moving in your golf swing.

From the assessment, an efficient fitness program can be created. It also gives you and your swing coach important information about your strength and flexibility that will help you make more informed decisions about your game. Dr. Rose says it best.

“If you don’t test, it’s just a guess.”

To paint a better picture of how an assessment can help, let’s look at a major swing flaw that most of us understand: coming “over the top” with a driver. This move has been responsible for more golf anguish than I care to quantify, but the problem usually stems from an issue with shoulder mobility, which causes a loss of posture.

There’s a lot of ways to try and fix coming over the top from a mechanical standpoint, but they’re often just band-aids. For long term improvement, you’ll need to get to the source of the problem.

One of the TPI assessments used to look at shoulder mobility is called the 90/90. With better shoulder mobility, golfers are generally more efficient with their longer clubs. It allows them to swing from the inside more easily and shallow their angle of attack.

To perform this test correctly, stand tall and hold your right arm out to your side with 90 degrees of flexion. Now, without letting your upper-body bend backward, try to externally rotate your right hand as far as possible (up and back). Only continue rotating as far as the body will allow with no compromises in your posture and never perform this test to the point of pain or discomfort.

Once the arm is fully externally rotated, grade the degrees of rotation. Your range of motion will fall into one of the following three categories:

  1. Less than Spine Angle: The forearm does not externally rotate past the spine angle (usually less than 90 degrees). This is not good.
  2. Equal to Spine Angle: The forearm is parallel to the spine angle (usually 90 degrees). This is good, but not great.
  3. More than Spine Angle: The forearm externally rotates past the spine angle (usually greater than 90 degrees). This is great.

Repeat the process with the other arm.

The next portion of this test will be to complete the same process with only one change — perform the test while you are in your golfing set-up posture with a 5 iron. Raise your elbow and arm to the 90/90 position and rotate the hand externally. Observe the forearm, spine-angle relationship in the same fashion as during the standing portion of the exam and repeat it on the opposite side.

This test is designed to highlight any limitations in mobility of the glenohumeral joint and/or stability of the scapulo-thoracic junction.

More specifically, the 90/90 test measures range of external rotation in the shoulder and a golfer’s ability to maintain scapular stability in a golf posture. We look at the amount of external rotation in each shoulder from a standing position and then compare that range to how the shoulder rotates in the golf posture.

Many golfers will lose range of motion in their golf posture due to a lack of scapular stability. This will cause them to lose their posture and stand up in their downswing, which can lead to coming over the top with the driver.

Other times the lack of scapular stability or poor posture causes the shoulder blade to elevate or flare, and this changes the orientation of the shoulder joint. This greatly reduce the amount of external rotation in the shoulder joint and causing a steep position in the downswing instead of the sweeping position that is preferred.

If you understand what your body can do (and not do), you can fix your physical limitations and address your swing mechanics with your teaching professional.

    Dave, great job explaining of the most critical tests in the screen and how it effects the swing. All of my students go through a screen, because I need to know what I’m working with. And as for Pat and Bogus, fitness in golf is here to stay and is only going to be a bigger part of it. People want to get better and for most players if they can improve movement and balance they can get better. You are only as strong as your weakest link. TRIAN, PRACTICE, PLAY AND BELIEVE!

    The usual let’s find a way to take money from rich golfers. Better to go to a chiropractor for a few visits. Some will give assessments and initial X-rays free to attract new clients. Even if not, at least you have a doctor, instead of some guy who went to a 3 day seminar.

    If I’ve insulted anyone I apologise, but it’s how I see it.

      In fairness, I’ve had the assessment done, and it actually shed some light on several things. I suppose I would quibble about the price a little but it wasn’t useless.

      I will say, though, that the “program” that was given was not terribly useful. I would have fixed many of the issues identified much quicker had I been introduced the barbell much sooner.

      Very little that is identified can’t be fixed by a good strength training program.

      Hi Dave

      If you have a look around your local area you will likely find that many of the TPI certfied practioners are actually Physical Therapists or Chiropractors as well. Look for a TPI level 2 or 3 Medical Professional.
      I am personally a golf physiotherapist in Perth Australia. See my website http://www.perthgolfphysio.com if you want more info.

    Dave has been an important partner along with my PGA teaching professional in keeping my swing in tune as I have aged into my late 50’s. Dave understands the limitations of a senior golfer yet trains very successfully Division 1 collegiate athletes not only in golf but also skill position football players and track athletes. I have worked with several trainers since I left college in 1977 and Dave is by far the most professional of any. If you are a golfer live or work in Southeastern Michigan do yourself a favor and contact Dave.

      Noah, your son has incredible hand eye coordination. He also has great mobility and stability. It was amazing to watch. The best thing for him is to let him continue to move natural and not provide him with instructions. We as adults tend to disrupt the natural process of movement with our theories instead of allowing the natural growth process to occur. Continue to let him “enjoy” what he is doing instead of “working” at what he is doing.

    Pat, you are correct in the basic screenings. But for a low handicap golfer, more advance screens are needed by a professional who is trained and has the proper equipment to facilitate. Here is a link that will help those to understand more about all the screens that are available and how to perform them. http://Www.mytpi.com/improve-my-game

      Cara, you hit it right on the nail when you said “functional component needed” people tend to think that you just pick up a club and hit it. Golfers are athletes

  16. Joe

    Dec 11, 2014 at 5:30 pm

    There is a lot more components to fitness for golf just like the the many components to a golf swing. A program should be all encompassing that attack weak areas as well as making strong areas stronger. Golf fitness is a lot more than just hitting th ball further. If you need to hit it farther use a different club. Obviously it can help you hit it off the tee further, hit it out of the rough, and help with club face control to name a couple of things. The main reason golf fitness should be undertaken is to decrease the risk of injury so you can enjoy a lifetime of fun.Look forward to reading more. Great article.

    Although fitness has it’s place in golf, it’s being blown out of proportion lately due to this trend follow society. Without getting into a rant, simply put, for some fitness will help their game to an extent, for some it will do nothing, for some it may even hinder their game (removing focus from the mental aspects and technique of the swing itself). We could name several players, who follow basic fitness routines, are not the most flexible/strong/agile, but they can play lights out. Many of the players before the 2000’s actually had no true fitness regimine, some played other sports. Hell, even Tiger followed unorthodox methods such as running 30 miles a week…but it worked for him! As we get more “science-based” with our training and research when it comes to fitness and even the swing, I won’t even get into launch monitors lol (Faldo played a spinny push cut under the gun in majors that would give horrific launch ratings, but under immense pressure it worked for him). We’re losing the essence that makes golf. I have trained my behind off for tennis and basketball because I had to, but golf fitness to me is a bit of a stretch. The 60 year olds at my golf course kicking the collegiate players a** daily is a testament to how much fitness is worth in golf. Yes you need a functional, pain-free, and somewhat athletic body to perform in golf but let’s not make it bigger than it is.

    • Dave Davis

      Dec 11, 2014 at 10:46 pm

      Bogus, you are correct about the players prior to 2000. But golf fitness is about injury prevention in my program. If a muscle is weak, then compensation takes place and eventually injury follows. On the tour, golf was a 6 month game. Now its 10 months and if players are not in shape, the chance of injury is high. Yes, like any other sport fitness can provide stronger muscles. But if you ask any professional strength and conditioning coach that works with high level athletes like i do, they will tell you that the focus is on strengthening for injury prevention. An athlete can not get better performance if their sidelined with injuries

    • Pat

      Dec 12, 2014 at 1:27 pm

      I don’t think you realize that golf fitness isn’t necessarily going to lower one’s handicap like you are stating. That part of golf is talent and practice based. It’s main purpose is injury prevention and strengthening and activating fast twitch muscle fibers so that everything fires faster hence more distance. My driver swing went from 110mph to 133mph at one point(former Japanese long drive competitor)and now I can still crank it up to 122mph because of my bodybuilding backround and my incorporation of sports fitness in general. What has slowed me down is numerous injuries throughout the years and age.

    A TPI screening and exercise program is one of the best things I’ve done for my golf game. Over the last 10 months my swing has improved along with scoring and so has my fitness handicap…+3 at my last re screen down from 19 when I started.

      Dec 11, 2014 at 2:39 pm

      All these golf “fitness” institutes are great, however only people that have money can afford to go to these places. Acquiring enough knowledge to incorporate at the gym is quite simple, yet I’m shocked at how lazy golfers in general are in regards to golf fitness. I’m in the golf and fitness industry(ACE cert.) and have a bodybuilding backround. Started working out since I was 19 years old. I’m in my mid 30’s. Currently 5’7, 160 pounds, 9% bodyfat, very flexible and I my swing speed is 120+mph. I have been 205, 8% bodyfat before in my bodybuilding days. I have learned more reading books, internet and talking to well respected people in the fitness/bodybuilding industry for sports exercise in general compared to anyone I’ve talked to in the golf fitness industry or these golf fitness institutes and seminars I’ve been to. If you people would take a little time out of your day to look up sport specific exercises on the internet and do a little research, it would save a ton of money compared to going to these golf fitness facilities which charge ridiculous amounts of money for their programs.

        Dec 11, 2014 at 10:51 pm

        Pat, there is some great information on the web with great exercises. Yes, golf fitness is expensive just like golf. Thats why its best to at least invest in an assessment to know what to work on. Like Dr. Rose stated “if you don’t test, its just a guess”

        • Pat

          Dec 12, 2014 at 6:25 am

          Dave, you realize that you can perform these flexibility tests on yourself right? No need to pay a fitness instructor or personal trainer for this. I understand you’re trying to help golfers but at the same time, you are also promoting your business(nothing wrong with that).

    This is the most enlightening piece of information I’ve seen in a long, long time (maybe ever) pertaining to an individual’s physical ‘ability’ to accomplish a first-class golf swing. If an amateur golfer really wants to improve his or her golf swing this should be an area that receives their #1 attention from a physical standpoint.

    • Dave Davis

      Dec 11, 2014 at 2:18 pm

      B,you are so correct. If a person is only strengthening the areas that are strong, then you don’t get better overall. Just better in the areas that are strong.

What to look for in a golf instructor: The difference between transformative and transactional coaching

Published

on

Golf instruction comes in all different styles, methods, and formats. With that said, you would think this would be a good thing due to there being so many different types of people in the world. However, it is my opinion that the lack of standardization within the industry makes it confusing for the athlete to determine what kind of golf instruction they should seek out.

Before we can discuss what may or may not be the best type of instruction for yourself, first we need to know what our options are. Whether we are taking a “broad-spectrum approach” to learning or a more personalized approach, it is important to understand that there are differences to each, and some approaches are going to take longer than others to reach goals.

Broad-Spectrum Approach

Welcome to the world of digital golf instruction, where tips from the most famous coaches in the world are a click away. The great thing about the internet and social media for a golfer is there has never been more access to the top minds in the field—and tips and drills are plentiful. With that said, with there being so many choices and differing opinions, it can be very easy to become distracted with the latest tip and can lead to a feeling of being lost.

I would describe “internet coaching”—or YouTube and Instagram surfing—as transactional coaching. You agree to pay, either a monthly fee or provide likes or follows and the professional provides very generalized tips about the golf swing. For athletes that are new to golf or golf instruction, this tends to be the first part of their process.

There are people who prefer a more transactional approach, and there are a ton of people having success working together over the internet with their coach. With that said, for someone who is looking for more of a long-term individualized approach, this may not be the best approach. This broad-spectrum approach also tends to be the slowest in terms of development due to there being a lot of trial and error due to the generalized approach and people having different body types.

Individual Transactional Coaching

Most people who are new to golf instruction will normally seek out their local pro for help. Depending on where you live in the country, what your local pro provides will vary greatly. However, due to it being local and convenient, most golfers will accept this to be the standard golf lesson.

What makes this type of instruction transactional is that there tends to be less long-term planning and it is more of a sick patient-doctor relationship. Lessons are taken when needed and there isn’t any benchmarking or periodization being done. There also tends to be less of a relationship between the coach and player in this type of coaching and it is more of a take it or leave it style to the coaching.

For most recreational or club-level players, this type of coaching works well and is widely available. Assuming that the method or philosophies of the coach align with your body type and goals athletes can have great success with this approach. However, due to less of a relationship, this form of coaching can still take quite some time to reach its goals.

Individual Transformative Coaching

Some people are very lucky, and they live close to a transformative coach, and others, less lucky, have had to search and travel to find a coach that could help them reach their goals. Essentially, when you hire a transformative coach, you are being assigned a golf partner.

Transformative coaching begins with a solid rapport that develops into an all-encompassing relationship centered around helping you become your very best. Technology alone doesn’t make a coach transformative, but it can help when it comes to creating periodization of your development. Benchmarks and goals are agreed upon by both parties and both parties share the responsibility for putting in the work.

Due to transformative coaching tending to have larger goals, the development process tends to take some time, however, the process is more about attainment than achievement. While improved performance is the goal, the periods for both performance and development are defined.

Which One is Right for You?

It really depends on how much you are willing to invest in your development. If you are looking for a quick tip and are just out enjoying the weather with your friends, then maybe finding a drill or two on Instagram to add to your practice might be the ticket. If you are looking to really see some improvement and put together a plan for long-term development, then you are going to have to start looking into what is available in your area and beyond.

Some things to consider when selecting a coach

  • Do they use technology?
  • What are their qualifications when it comes to teaching?
  • Do they make you a priority?

As a golf coach who has access to the most state-of-the-art technology in the industry, I am always going to be biased towards a data-driven approach. That doesn’t mean that you should only consider a golf coach with technology, however, I believe that by having data present, you are able to have a better conversation about the facts with less importance placed on personal preference. Technology also tends to be quite expensive in golf, so be prepared if you go looking for a more high-tech coaching experience, as it is going to cost more than the low-tech alternative.

The general assumption is that if the person you are seeking advice from is a better player than you are, then they know more about the golf swing than you do. This is not always the case, while the better player may understand their swing better than you do yours, that does not make them an expert at your golf swing. That is why it is so important that you consider the qualifications of your coach. Where did they train to coach? Do they have success with all of their players? Do their players develop over a period of time? Do their players get injured? All things to consider.

The most important trait to look for in a transformative coach is that they make you a priority. That is the biggest difference between transactional and transformative coaches, they are with you during the good and bad, and always have your best interest top of mind. Bringing in other experts isn’t that uncommon and continuing education is paramount for the transformative coach, as it is their duty to be able to meet and exceed the needs of every athlete.

The importance of arm structure

Published

on

How the arms hang at address plays a vital role in the golf swing. Often overlooked, the structure in which we place the arms can dictate one’s swing pattern. As mentioned in the article How Posture influences your swing, if you start in an efficient position, impact is much easier to find making, the golf swing more repeatable and powerful.

To start, I opt to have a player’s trail arm bent and tucked in front of them with angle in the trail wrist. While doing so, the trail shoulder can drop below the lead with a slight bend from the pelvis. This mirrors an efficient impact position.

I always prefer plays to have soft and slightly bent arms. This promotes arm speed in the golf swing. No other sports are played with straight arms, neither should golf.

From this position, it’s easier to get the clubhead traveling first, sequencing the backswing into a dynamic direction of turn.

@peterthomson

When a player addresses the ball with straight arms, they will often tilt with their upper body in the backswing. This requires more recovery in the downswing to find their impact position with the body.

A great drill to get the feeling of a soft-bent trail arm is to practice pushing a wall with your trail arm. Start in your golf set-up, placing your trail hand against the wall. You will instinctively start with a bent trail arm.

Practice applying slight pressure to the wall to get the feeling of a pushing motion through impact?. When trying the drill with a straight trail alarm, you will notice the difference between the two? arm structures.

What is ground force in the golf swing?

Published

on

There is no doubt about it, the guys and gals on tour have found something in the ground—and that something is power and speed. I’m sure by now you have heard of “ground reaction forces”—and I’m not talking about how you “shift your weight” during the golf swing.

Ground force in the golf swing: Pressure and force are not equal

With respect to ground force in the golf swing, it’s important to understand the difference between pressure and force. Pressure is your perception of how your weight is being balanced by the structure, in this case, the human body. Your body has a center of mass which is located roughly one inch behind the belt buckle for men and about one inch lower in women. When we shift (translate and/or torque) the center of mass, we create a pressure shift as the body has to “rebalance” the mass or body. This pressure shift can help us understand some aspects of the golf swing, but when it comes to producing power, force and torque are where it’s at.

Pressure can only be expressed in relation to the mass or weight of the body. Therefore, if you weigh 150 pounds, you can only create 150 pounds of pressure at one time. However, when we direct that mass at a larger object than our mass, all of a sudden that larger mass directs an opposite and equal reactionary force. So now, when a human being “pushes” their legs against the ground and “feels” 150 pounds of pressure, they now get 150 pounds of force directed back towards them from the ground, creating a total of 300 pounds of force that allows them to jump off the ground in this scenario.

If ground reaction forces don’t have anything to do with the “weight shift,” then what do they affect? Everything!

Most people use the same basic ingredients to make chocolate chip cookies. However, almost everyone has chocolate chip cookies that taste slightly different. Why is that? That is because people are variable and use the ingredients in different amounts and orders. When we create a golf swing, whether we are aware of it or not, we are using the same basic ingredients as everyone else: lateral force, vertical torque, and vertical force. We use these same three forces every time we move in space, and how much and when we use each force changes the outcome quite a bit.

Welcome to the world of 3D!

Understanding how to adjust the sequencing and magnitude of these forces is critical when it comes to truly owning and understand your golf swing. The good news is that most of our adjustments come before the swing and have to do with how we set up to the ball. For example, if an athlete is having a hard time controlling low point due to having too much lateral force in the golf swing (fats and thins), then we narrow up the stance width to reduce the amount of lateral force that can be produced in the swing. If an athlete is late with their vertical force, then we can square up the lead foot to promote the lead leg straightening sooner and causing the vertical force to happen sooner.

While we all will need to use the ground differently to play our best golf, two things need to happen to use the ground effectively. The forces have to exist in the correct kinetic sequence (lateral, vertical torque, vertical force), and the peaks of those forces need to be created within the correct windows (sequencing).

  • Lateral force – Peak occurs between top-of-swing and lead arm at 45 degrees
  • Vertical torque – Peak occurs between lead arm being 45 degrees and the lead arm being parallel to the ground.
  • Vertical force – Peak occurs between lead arm being parallel to the ground the club shaft being parallel to the ground.

While it may seem obvious, it’s important to remember ground reaction forces are invisible and can only be measured using force plates. With that said, their tends to be apprehension about discussing how we use the ground as most people do not have access to 3D dual force plates. However, using the screening process designed by Mike Adams, Terry Rowles, and the BioSwing Dynamics team, we can determine what the primary forces used for power production are and can align the body in a way to where the athlete can access his/her full potential and deliver the club to the ball in the most effective and efficient way based off their predispositions and anatomy.

In addition to gaining speed, we can help athletes create a better motion for their anatomy. As golfers continue to swing faster, it is imperative that they do so in a manner that doesn’t break down their body and cause injury. If the body is moving how it is designed, and the forces acting on the joints of the body are in the correct sequence and magnitude, not only do we know they are getting the most out of their swing, but we know that it will hold up and not cause an unforeseen injury down the road.

I truly believe that force plates and ground reaction forces will be as common as launch monitors in the near future. Essentially, a launch monitor measures the effect and the force plates measure the cause, so I believe we need both for the full picture. The force plate technology is still very expensive, and there is an educational barrier for people seeking to start measuring ground reaction forces and understanding how to change forces, magnitudes, and sequences, but I’m expecting a paradigm shift soon.
