HIT THE GOLF BALL FURTHER

LPGA_Driver_SwingI think just about everyone wants to hit the ball farther.  We have covered a lot of topics on how to increase power and speed in your golf swing.  But we haven’t really gotten into the “why”.  Once you understand the why I believe it is much easier to apply those principles into your training.  To understand how power is developed, let’s first look at how muscles work. There are two parts to the activation of a muscle. First, there is the power supply. This is your nervous system. Without the signal from the nervous system, no muscle could contract. The name of the nerve that signals a muscle is called a motor nerve. Second is the muscle itself. A muscle is made up of hundreds of micro-contractile fibers, called myofibrils bundled into muscle fibers, which are bundled into muscles. The combination of the motor nerve and all the muscle fibers it innervates is called a motor unit. One motor nerve can actually supply thousands of muscle fibers.

Power is the combination of speed and force. Force is generated by the muscles. Therefore, one key to power is to recruit more motor units. The more motor units you activate, the more muscle fibers will engage and the more force you can generate. The activation of one motor neuron will result in a weak but distributed muscle contraction. The activation of more motor neurons will result in more muscle fibers being activated, and therefore a stronger muscle contraction.

The size principle states that in order to move a load, motor units are recruited from smallest to largest. In practice, this means that slow, low-force muscle fibers are activated before the fast, high-force muscle fibers. As more force is needed, motor units are recruited in a precise order according to the magnitude of their force output, with small units being recruited first. So what does this have to do with power? It is very simple, if you want to recruit more motor units (which you do for power), then you should focus your training on trying to activate the larger motor units. If you get to the large motor units, because of the size principle, you are also getting the smaller units as well.

How do you recruit larger motor units? Based on the size principle, for an explosive athlete, you want to recruit as many motor units as possible with every exercise you perform. There are two main ways to accomplish this task:

      Lift as heavy as possible

      Lift as fast as possible (100% effort)

With heavy loads, you are engaging all your motor units because of the amount of effort required to perform the lift. With lighter loads, you are engaging all your motor units when you give 100% effort into the movement. That 100% effort is the key to activating all your motor units with lighter loads.

For power and strength training, we want to activate the large motor units as stated earlier. Unfortunately, our large motor units were really designed for safety. In other words, if you were being chased by a tiger, these fibers would kick in to help you save your life. It is called your “fight or flight” system. They can be used to deliver a knockout punch or used to explode into the sprint for your life. Either of those activities can only be sustained for a short period of time. These muscles use a different type of energy system than other activities that we perform in a slow controlled fashion. This is energy that is stored right in the muscle and easy to access. However, since there is only a short supply of this energy, it can only last for 5-15 seconds.

Therefore, when training for power (engaging all your motor units), you literally only have an average of 10 seconds available to do this. This is why typical Olympic lifting training volumes have short numbers of reps and high number of sets. For example, the typical training recommendations that most of us have seen is 3 sets of 8 reps. Those 8 reps will definitely take longer than 10 seconds to perform. If you switch this to 8 sets of 3 reps, you now have a greater chance of developing true power.

Learning how to utilize your motor units is part of the strength training process. In order to increase strength, you can do one of two things: Learn how to recruit more motor units or develop more muscle fibers. In order to create more muscle fibers you need to tear and rebuild muscle. This requires heavy strength training, rest and recovery, plus the hormone testosterone. For many people, this type of strength training is not desirable. It has the risk of injury and inherent soreness associated with it. Kids don’t even have the levels of testosterone to really utilize this method, so it is not an option for the early developing years. The good news is, anyone can learn how to recruit more motor units.   Lift Heavy, Lift Fast.

HydrationHydration on the Course It's finally starting to get warmer and we are seeing the temperatures jump up pretty quickly. These high temperatures can sneak up on us and it’s important to keep up on hydration- especially when playing a round of golf. In order for our bodies to function, we have to replenish its water stores. After all, the body is made up of 70% water! Proper hydration will help you: Make better decisions on the course Minimize muscle soreness after golf or your fitness routine Manage stress on and off the course Maintain your ability to drive the ball...
Mobility MayMobility May In celebration of ‘Mobility May’ it seemed only fitting that we talk about mobility. Mobility and flexibility, or lack of, is one of the most common reasons golfers come to our facility. Most people think that mobility and flexibility are the same, when in fact they are two very different concepts. Flexibility is the ability of a muscle, or muscle group, to lengthen passively through a range of motion. Mobility is the ability of a joint to move actively through a range of motion. Mobility also takes into account the component of motor control with the...

Is Your Neck Killing your GameIs Your Neck Killing Your Game Many golfers have limited range of motion with their golf swing. Limitations during the back swing can be particularly problematic. There can be numerous factors for these limitations. Decreased external rotation with the lead hip, limited internal rotation of the trail hip or limited thoracic rotation are some of the common culprits. One area that is often overlooked with the golf swing is cervical rotation, or turning your head side to side. Many people don’t think that movement will have an impact on your swing but it is actually one of th...
Do you know how to Practice?Do you know how to Practice? Let’s face it, hitting golf balls on the range just isn’t as fun as playing a round with your buddies. But let’s say you go out to the range every once and awhile to work on your game. Did you know that how you practice (how most people I see on the range practicing) could be actually hurting your game? Or at the very least not helping. Blocked vs Random - Let’s talk about the different styles of practice first. There are 2 main styles of practice, Blocked and Random. Blocked practice is when you go out and hit the sam...
Teaching an Old Dog New TricksTeaching an Old Dog New Tricks Have you ever stood over a golf ball with full confidence only to hit a terrible shot and just wonder how in the world you just did that? Have you ever wondered why you need to keep working on the same swing drills over and over? The answer is in how our brain learns skills. There are 2 types of skills, motor and cognitive. Motor skills are like riding a bike or swinging a golf club. Cognitive skills are like learning a new language or mathematics. Our brain stores these skills in 2 completely different ways. For example, if you learned...
The Importance of Sleep in RecoveryThe importance of Sleep in Recovery Golfers ask me all the time, ‘what are the best tools for recovery?’ Everyone wants to know all the new andgreatest gadgets and tools to help with recovery. This list can get lengthy and expensive asthere is no shortage of different “recovery” tools on the market. Foam rollers, trigger point balls, NormaTeccompression boots, MarcPro, massage guns, hyperbaric chambers, saunas, floattanks….I could go on for a while. Weoffer a lot of these tools in the office to help with injury recovery and mostdo have a lot o...
The X Factor - Torso RotationThe X Factor - Torso Rotation One of the first tests we take golfers through during the TPI assessment is the Torso Rotation Test. This test looks at the golfer’s ability to rotate the upper body independently from the lower body, or dissociate. This is an important skill for properly sequencing the backswing and generating a good separation or coil. This is the “X-Factor”, creating the whip-like action in your swing and one of the key factors in power generation. For the test, start in a normal “five-iron posture” and then cross your arms across yo...
Muscle Activation Techniques (MAT)MUSCLE ACTIVATION TECHNIQUES (MAT) Many of you may have become familiar with Muscle Activation Technique (MAT) this past year or so. Although the technique has been around for years and utilized by us on the healthcare side, it has become very popular in the golf world due to the success of Bryson DeChambeau. Bryson is a huge advocate for MAT because it has helped him not only stay healthy but also improve his power and performance. MAT is an exercise method that tests for individual muscle weakness and when found, activates them through a simple technique to restore both t...
Hip Hinge Advanced ProgressionsHip Hinge Advanced Progressions The hip hinge is one of the most fundamental movements for normal activities of daily living but also extremely important for the golf swing. The hip hinge involves a controlled bending at the hips by pushing the butt backwards and keeping the spine straight, followed by extension of the hips (thrusting the butt forward) to come back upright. The most common exercise that involves the hip hinge is the deadlift. Done correctly, the hip hinge is very physically demanding. It involves mobility, flexibility, and strength throughout the entire body....
Single Leg BalanceSINGLE LEG BALANCE The screen that we hear the most groans with during our golf fitness assessments is the single leg balance screen. Almost every golfer knows that they are going to be bad at it. The funny part about it is that it is probably the easiest fitness characteristic to get better at, quickly. The screen measures your overall balance and highlights any proprioceptive imbalances from left to right as well as overall “core” stability. Our bodies use 3 internal control systems to help maintain balance throughout the golf swing: eyes, ears (inner ear), and...
Staring a Strength ProgramStarting a Strength Program Last week we talked about things NOT to do when starting a strength training program. If you avoid making a lot of those common mistakes then you will probably be on a good path with your program. So now that you know what not to do, let’s talk about the easiest way to start a basic strength training program. Assess, Don’t Guess You will always hear me say an assessment is the first step when working towards any goal. Can you start a program without an assessment? Sure. But entering into a fitness program without an a...
What Not to Do when Starting a Golf Fitness ProgramWhat Not to Do when Starting a Golf Fitness Program Guessing, Not Assessing Not assessing your weaknesses and strengths is one of the worst things you can do during a training program. If you are going into a workout without a clear goal for the day, month, or even year then you are not getting the most out of your workouts. There are benefits to exercise for general health but if you really want to improve your golf game then you need to know the areas that need to be worked on. Having a professional take you through a TPI screen is a great place to start. Imprope...
Pull StrengthPull Strength We have spent the last month talking about speed and power production and how to incorporate that into a training program. If you watched the US Open this past weekend, you saw how advantageous strength and power can be. The style of play where you just hit it as far as you can and deal with whatever lie you have hasn’t been very well received by traditional golfers, but we can see that it can clearly be effective. Sure, power is great for hitting the ball farther, but just as important (or more important) was the strength to hit out of that thick rough. Ev...
Elbow-Wrist Release PowerElbow-Wrist Release Power The last power source we like to develop iswrist and elbow power. Wrist releasespeed has been shown to be very important in adding power to the swing. The wrist can actually create power in 3different directions. It can extend,rotate and hinge. The most powerfulgolfers utilize all three planes for speed and power. The elbow can also be used as another link inthe chain of power, and is commonly used by the long drive tour players. To incorporate the elbow link, the playerwill have to bend the elbow at the top of the backswing. This allows th...
Arm Chopping PowerArm Chopping Power The ability to deliver explosive speed withthe arms is one of the most important aspects for power in the golf swing. We call it the Arm-Chopping motion, becausethe arms need to start up over the trail shoulder and explosively fire downacross the body to over the lead hip. Many players tend to eliminate this power source by trying to keep theirarms pinned to their chest during the downswing. This may help improve accuracy but it willdefinitely limit power development. Here are some examples of exercises weincorporate to develop arm-chopping power: χ...
Truck Rotary PowerTrunk Rotary Power The “trunk” refers to the combination of the pelvis and thorax. By monitoring the rotary speeds a player develops in those two body segments we can get a good indicator of what type of power they can ultimately generate in the club. The best way to measure these speeds is by analyzing a kinematic sequence with a 3D motion capture. Not only does the kinematic sequence give us the speeds being produced but it also tells us the order in which they are being utilized during the swing. If that sequence is out of order a lot of power can be lost in...
Vertical Thrust PowerVertical Thrust Power Have you ever noticed that many kids have a large jump during their downswing? The reason is because the jump (vertical thrust) is one of the first power sources developed in kids. The vertical jump is also a technique used by some of the most powerful golfers in the world. Despite vertical thrust power being arguably the greatest source of power it is one that is often neglected by golfers. We utilize some of the following methods to develop strength, speed, and power for vertical thrust: ● Skipping warm-up ●...
Developing Power in the Golf SwingDeveloping Power in the Golf Swing To develop power we first need to understand where power is needed. With any power source, you need to develop strength and speed in all areas. The four power sources that influence the golf game the most are: Vertical Thrust Power Trunk Rotary Power Arm-Chopping Power Elbow-Wrist Release Power Vertical Thrust Power Have you ever noticed that many kids have a large jump during their downswing? The reason you may see a jump is it is one of the first power sources developed in kids. If the other three power sources have not develope...
Low Back PainLow Back Pain Low back pain is the most common injury we see in golfers. It is estimated that more than half of you reading this article will have experienced low back pain that has affected your performance at some point this season. And at least 50% of you have missed 3-6 weeks of participation because of the pain. That is a big deal! The most common cause for low back pain in Tour Pros is overuse. I doubt too many of you are hitting more balls than Touring Pros. The most common cause of LBP in amateurs is mechanics. So here’s the best part, low back pain is very prev...
Golfer's Elbow vs. Tennis ElbowGolfer's Elbow vs. Tennis Elbow When these elbow injuries were being namedGolfer’s and Tennis Elbow there really wasn’t a whole lot of thought put intoit. Golfers actually get Tennis Elbow5-6x more than Golfer’s Elbow. So what’sthe difference? Tennis Elbow (lateralepicondylitis) involves an injury to the extensor muscles (backside of yourforearm and outside of the elbow) and Golfer’s Elbow involves an injury to theflexor muscles (palm side of your forearm and inside of elbow). For a long time these injuries wereconsidered to be “tendinitis&r...
Opposite Speed TrainingOpposite Speed Training One of the most common mistakes I see golfers make with their fitness programs is trying to be too “golf specific” and replicate the golf swing with their exercises. Most of the exercises to increase power and speed have nothing to do with a swinging motion. In fact, when we do include rotary/swinging movements we actually train in the opposite direction more frequently. This is a theory that was given the name “The Big Break Theory” by TPI Advisory Board member, Dr. Tom House. We have noticed that there seems to be a strong...
Upper Body Modifications for PowerUpper Body Modifications for Power The upper body generates the highestrates of speed in the golf swing. Therefore, any modifications that we canperform here will pay off big time in the long run. However, these modifications to greatlyincrease clubhead speed also come with a greater risk of reducingaccuracy. But right now we are justtrying to increase speed and power. Onceyou do that then you learn how to control it. If you go back and read last week’s article on lower body modificationsand thought those tips were completely different from what most teachingprofessionals...
Lower Body Modifications for PowerLower Body Modifications for Power When it comes to modifying swing mechanics for power, let’s begin by stating the obvious - the fastest way to increase your distance is to make solid center face contact on the club! So most players could easily pick up a few yards with just a standard golf lesson and proper fitting. With that said, we will discuss some of the techniques and swing modifications that have been shown to help generate more power. However, none of these will matter without solid contact on the club face. The lower body has the most modifications for power and can...
Shoulder Mobility CorrectivesShoulder Mobility Correctives Last week we went over one of the mobility screens for the shoulder. The ability to obtain adequate external rotation, and maintain it, is crucial for staying in posture during your backswing. We want to be able to externally rotate past your spine angle. If you are unable to reach that position in either posture you may have a mobility problem with your shoulder. If you are able to rotate past your spine angle in the upright position but lose range of motion when in your golf posture you may have a stability issue around your shoulder blade (scapul...
Shoulder Assessment – 90/90 TestShoulder Assessment – 90/90 Test The 90/90 Test is one of the primary assessments we use to look at shoulder mobility, specifically external rotation. More importantly, we test the golfer’s ability to maintain that range of motion while in a golf posture. When we bend forward to get into a golf posture, we can lose range of motion in the shoulder if we don’t maintain a good, stable position of the shoulder blade. Reduced range of motion in the shoulder can lead to a flat shoulder plane or loss of posture, and cause us to get out of position on the ba...
HydrationHydration As the temperature increases, it’s important to keep up on hydration- especially when playing a round of golf. In order for our bodies to function, we have to replenish its water stores. After all, the body is made up of 70% water! By staying hydrated, you will be able to make better decisions on the course, decrease stress levels, and recover better between rounds. Dehydration on the course can happen more quickly than you may believe. It only takes 1-2% loss of body weight to start seeing the effects of dehydration. Think about how much energy you’re exerting...
Protein 1st ThingProtein should always be the first food on your plate Protein should always be the first food on your plate, as the word protein stems from the Greek word proteos , or “of primary importance.” Why is it so important? Protein is made up of twenty-four amino acids, some of which your body isn’t able to produce on its own. The only way your body is able to get these amino acids, is by taking them in through the diet. Amino acids are responsible for many functions of the body such as repairing tissue, boosting energy, improving metabolism, and increasing muscle m...
Sway - The Hip KillerSway - The Hip Killer A sway is any excessive lower body lateral movement away from the target during the backswing. If we aren’t rotating around the hip but moving laterally it will cause the pelvis to side bend and anterior tilt excessively which just loads the hip and dramatically reduces the intra-articular space in the hip. If you do this enough it will most certainly lead to hip complications down the road. Mobility restrictions with hip internal rotation, ankle eversion, thoracic spine extension/rotation, tibial internal rotation, or stability limitations in the hip...
