Robert Goldman, Chairman of the Board, A4M and Director of WAAAM Dr Ron Klatz What I would like to share with you is an an extraordinary new approach to looking at the human body that can spur breakthroughs in medicine, fitness and overall health. It is an entirely new approach that helps us understand the mysteries to why the body breaks down, doesn’t heal and degenerates into chronic state of suffering. It also provides many secrets to restoring human performance and preserving the health of the human body. Not long ago, I began to see the human form through a whole new lens. The lessons taught in medical schools, medical books and scientific papers about how the body works and how it breaks down, though based on modern medical constructs, just didn't add up. I felt that current teachings in the medical and fitness industries were missing something big. There were just too many unexplained mysteries that perplexed doctors and scientists and left patients feeling hopeless, frustrated and in a chronic state of pain and suffering.
There is a gap in the way doctors think and do and what athletes and patients require for top performance Athletes and coaches are trained with jumping and bounding yet doctors never recommend this for patients if something doesn’t make sense, keep asking questions until you find the answers. I felt these answers would provide us with the secrets to the best approach to allow us to reach the true potential of our human body. I took off my white coat and considered the human form from different logical points of view: a mechanical engineer, an anatomist and a physicist. I then combined this new perspective with my years of experience interviewing, treating and training hundreds elite athletes in many sports from around the world. What I found was fascinating to me, doctors around the world and I’m excited to share it with you! How does a man 5’10 jump over a barrior 7’4” while some of us cannot run, cant walk or even get out of a chair without pain There are explanations for these mysteries which are based on science on the laws of physics engineering and the laws of nature Why is impact training such as plyometric the secret to high level performance yet this is considered unhealthy by the medical profession? There is a gap between what coaches require to keep their athletes at top performance and what doctors can deliver for treatment This happens at the highest level and obvious at the local level as well I m going to describe a new model of looking at the human body based on the concept that the body is a giant human spring that may make understanding why this happens. Iʼm going to talk about a new model of looking at the human body that will change the way you will look at the body forever. I guarantee this presentation will give you a better understanding of how your body works, how it breaks down and what to do when it does. What I teach is based on the laws of engineering, physics, nature and common sense. After studying the lessons in this presentation you will begin to look at everything related to health and fitness differently -- from the approach you take with your patients as a doctor in examining and treating them, to advice on prevention. You will think differently about the approach you use in advising patients on diet and exercise. You will change the way you think all the way down to the shoes you wear and recommend for your patients. Bold statements? Yes, but the reason Iʼm so confident is because much conventional wisdom about the way the body works, completely disregards a vital component of how we are designed and how we function. That is the amazing human spring. After years studying biomechanics I discovered that the healthy and balanced human body acts like a giant spring. From the ground up, where your feet absorb 3,600,000 collisions with the earth annually, the joints of the human body are protected by a spring mechanism. The spring system plays a vital roll in human movement, allowing you to be more efficient by recycling energy through spring energy rather than through muscular work. Filling in this gap goes much of the way to explaining some central health mysteries including: *why we have a growing propensity for injuries *why we donʼt heal from simple injuries *why we are so tired *why our joints wear out leading to replacement surgeries *why treatment approaches simply donʼt work. As youʼll see later in this presentation, most chronic pain and many conditions from misdiagnosed fibromyalgia, chronic fatigue, arthritis, chronic injuries and chronic levels of inflammation -- even aging diseases related to chronically high levels of inflammation as well as weight management challenges -- can be successfully negated by correcting, strengthening, even supercharging the spring mechanism.
It is the human spring theory
Every movement you make is powered by a miraculous spring mechanism. Once you learn how it works, the important functions it serves, how it breaks down and locks, and how it effects so many aspects of your health, you will see why so many suffer and are misdiagnosed. Then when I teach you my new approach to releasing, strengthening and supercharging your human spring, you will understand why my patients recover when other approaches have failed. Understanding the human spring will help you understand how certain athletes can high jump seven feet over a bar or run fifty miles without stopping, while other people can't jog, walk, lift weights of even get up out of a chair without pain. The efficiency of your body's motion has everything to do with the integrity of your human spring. It is A Painful Misunderstanding of Human Engineering Unfortunately, the world doesn’t regard the body as a living spring. Consequently, they are missing out on the most important aspects of how the human body moves, protects itself, recycles energy and functions in a world governed by the laws of nature, physics, engineering and common sense. Today's current medical practices and exercise approaches defy the laws of nature, physics and engineering. Which means they'll never work. Period. Medical experts can't treat your body to the near perfect level that the Human Spring Approach � can. All current standard-of-care treatments including adjustments, mobilizations stretching, rehab exercises, injections, medications and surgeries are destined to fail to achieve true maximum medical improvement because the entire human spring is not considered. What does this mean to you? A lot. I'm certain that right now you, or someone you know, experiences some level of pain, whether it's during your workout or simply by bending over to tie your shoes. Am I hitting a nerve here? I thought so. Chronic pain and fatigue affect millions of people from every walk of life and every part of the world. What you are about to learn is that you are suffering needlessly and it's all because you follow the advice of professionals who embrace an approach to medicine that, in reality, isn't treating the root cause of your pain. In fact, they may be causing you to get worse! I know, that's some pretty strong language but after you read this book you will know it to be the truth.

HUMAN SPRING THEORY The human spring stores mechanical potential energy therefore it is an efficiency mechanism. The human spring absorbs forces of landings therefore it is a protective mechanism. The human spring allows the foot to land on uneven surfaces adjusting the body mechanics to the terrain. The human spring is integrated into the biomechanics therefore it is essential for stress/strain free motion Weakness or locking of the spring can lead to fatigue, increased risk for acute injury, inability to heal and accelerated aging of the body’s systems.
HUMAN SPRING So the arch of the foot is actually a leaf spring possessing spring energy in the engineering of the structure of the bones and ligaments that create the arch spring-like structure. This leaf spring of the foot is further loaded and unloaded with spring energy with the tendons that support it from above in a muscular cuff I call the " pronator-supinator cuff " or the " spring suspension system muscles " When we look at a very close view of the foot landing, we can see the tendons of the tibialis posterior stretching to lower the arch through spring loading. You can see the arch load. It becomes a spring configuration loading up the stretch energy of the tibialis posterior tendon and other cuff muscular tendons as other springs. In other words, the human foot is a marvel of engineering.

Stoxen Approach - Spring Mechanics - Hookes Law Hookes Law - The deeper the spring is depressed the more energy it recycles back into the walk, run, jump or spring Vital to Sports Vital to Activities of your patients daily life We want to train more spring into our patients musculoskelital systems 51 year old woman asked to jump Doctors tell patients not to jump Trainers tell athletes to jump more in fact do plyometrics The deeper the jump or the deeper the spring is depressed eccentricly the more energy it will return This means asking the 51 year old woman to jump from higher We tell them not to jump and wear cushioned shoes Cushioned shoes actually reduce the spring training to the spring Less adaptation and weaker over time This advances the aging, sarcopenia and osteopenia
ELASTIC DEFORMITY THE ABILITY OF THE SPRING TO DEFORM, STORE ENERGY, REFORM TO ITS EXACT ORIGINAL SHAPE, RELEASING ENERGY The ability of the spring to bend and return to its original shape Energy is developed when the spring loads in kinetic or potential energy Energy is released when the spring unloads at toe off releasing this energy This happens 2 ways Loading of the leaf spring of the arch of the foot Loading of the elastic muscle tendon mechanism of the pronator supinator cuff and achilles tendon
PLASTIC DEFORMITY THE HUMAN SPRING DEFORMS, STORES ENERGY, DOES NOT RETURN TO ITS EXACT ORIGINAL SHAPE, RELEASES LESS ENERGY The spring bends but does not completely return to its original shape Bunions Degeneration of the Meniscus Degeneration of the hip socket Herniated disc Cervical cranial headaches
Gait analysis No books on it We do a lot of walking! In one year we take 3,650,000 steps and 36,500,000 steps in 10 years So by doing the math, by our 30 th birthday we have taken 109,500,000 and by our 70 th birthday we have taken 255,500,000 steps. Now you can see how even subtle abnormal movement in the joints can add up to enough wear and tear of the cartilage to force you into a knee or hip joint replacement surgery. Walking is a learned activity - Walking is something we should never take for granted. First of all, walking is a skill that is learned. We’re not born with the skill to walk. We require the coordination of over 300 muscles to walk Examination Functional Kinematic Chain Tests :Locked Arch Check hold fingers in ears and walk duck walk Painful conditions calf jiggle pounding walk Foot Twist Dead Feel Stiff Man Syndrome
Step one: Evaluate the landing position of the spring Step two: Evaluate the spring and roll from supination to pronation Step three: Evaluation of the foot position under the center of gravity Step four: Evaluate for internal forces or stress on the spring
Running Injuries Most important is the ability of the spring suspension system to handle the force of the landings
Yield or maximum training force The maximum force allowed before Plastic Deformity Training principles are developed around this force For some they cannot even stand without exceding the yield For some the imacts of walking exceeds the yield For some the impacts of running exceeds the yield If I cannot run then when can I run We need a scientific way to answer this question or we will make a mistake that will lead to accelerated aging, condition or injury It is our responsibility to determine the capability of the patient - athlete Inform them where they stand Put a plan together to help them to reach their goals This is the
Pain and accelerated aging Silent and painful Inflammation Wear and Tear Stress and strain Abnormal motion Foundation Spring Mechanism Weakness I 致 e discovered that if we trace down arthritis and chronic pain, that accelerated aging comes from what I call 壮 i lent arthritic inflammation � and 叢 a inful arthritic inflammation � , this comes from locking or stiffening of regions of the human spring. We don 稚 always know our spring or springs are locked or restricted because the change lays silently undetected much of the time in the form of Silent Arthritic Inflammation and at times its painful in the form of Painful Arthritic Inflammation.We qualify the different types of inflammation in the human body - the musculoskeletal system in two different ways. Painful Arthritic Inflammation - is inflammation that you can feel; the inflammation levels are high enough to register in the brain. � Silent musculoskeletal inflammation is the inflammation exists dormant in the body, that is only felt with pressure or strain. You might refer to them as trigger points, knots or spasms.Wear and tear that causes the inflammation: which is caused by the stress and strain on the body or the physical structure, the joints, the actual springs: Abnormal motion creates the stress and strain. I have found that most of the root cause of all this is from a defect in the spring mechanisms.We now have a two major epidemics that drastically effect spring mechanisms as well as our overall health. These epidemics cause a cascading spiral effect of deteriorating health or acceleration of the aging process. 1.We have an obesity epidemic. Poor diet can lead to excess in silent systemic inflammation. 2.When we are overweight or obese this places a load the spring mechanisms cannot balance leading to a drop and lock and multi-joint strain on every spring mechanism and inflammation of the flooring system of the human body. The painful arthritis inflammation and silent arthritis inflammation condition is an epidemic because over 70,000,000 people in the United States alone take some form of drug for chronic pain.The combination of the two creates what I call a toxic soup effect and healing more difficult, we are tired all the time, in the state of brain fog, depressed and lacking the desire to get out of this rut we live in every day. We have acceleration of the diseases of aging associated with higher than normal levels of inflammation such as heart disease inflammatory, auto immune diseases and other diseases connected to high levels of inflammation.
HUMAN SPRING SUSPENSION SYSTEM Cuff Muscles – Tibialis Posterior, Tibialis Anterior, Peroneals, Spring Off 1 st two toes hold all the weight toes 3 – 5 balance Where Spring Breaks down metatarsal cuneiform joints
Remembering to keep your second toe pointing towards the target will allow you to accomplish many important positive changes in your gait. 1. It will allow you to have an alignment that will keep your knee hinging at the angle it was designed to hinge at reducing stress on the knee. 2. It will align your leg to allow the calf muscles to be aligned for the maximal contraction up the middle. This will maximize the venous return via the contraction of the calf to squeeze the blood back to fill the heart. 3. It will allow you to get maximum spring from your muscles. 4. It keeps your bodyweight from rolling over the inside edge of your big toe. This forces the big toe laterally and squeezes the rest of the toes together causing bunions and mortons neuromas.

Failure of Prevention Medicine
Causes of Weakness in the Human Spring Suspension System
Modern society has changed forcing us to wear shoes causing weakness Modern conveniences have taken the hunt out of our daily routine causing weakness
Plastic Deformity After running barefoot over 300 miles my shoe size went from an 8.5 to a 9.5 Why did the size change Did my foot enlarge from muscle size?
The foot deforms to the shoe shape This is plastic deformity Loss of ability to absorb forces of impact Loss in the ability to recycle energy Loss in the alignment We call this reduced performance Increase risk for injury Balance problems Aging
Why is a shoe helpful when we get older? Shoes cause the weakness in the spring mechanism and the plastic deformity that makes a supportive shoe necessary’

When does the spring mechanism begin to breakdown Breakdown of the spring mechanism is happening sooner due to obesity in children and a lack of exercise to counteract the forces overloading the spring mechanism This means accelerated aging of the musculoskeletal system and the sequela in the other bodies systems is happening sooner than previous generations Aging happens at every age Children must have a gait evaluation, spring check, diet, exercise and footwear advise to begin their anti-aging medical preventive approach

ANALYSIS OF HOW THE HUMAN SPRING HANDLES GREATER LANDING FORCES TAKING A LEAP FORWARD WITH THIS NEW APPROACH I AM ABOUT TO EXPOSE YOU TO - Performance running demands the combination of two types of strength defined as ‘absolute’ and ‘spring’ strength. A loss of either, makes running more risky, more stressful and damaging to the joints rather than more healthy. In short without both training regimes running becomes another tool to accelerate aging by way of a breakdown of the spring mechanism leading to abnormal movement patterns, the stress and strain, wear and tear, inflammation and every disease linked with inflammation aside from the pain. Absolute strength has been addressed in studies and in clinical practice. We educate and coach our patients in the practice of resistance exercises to increase absolute strength of the weight bearing joints, thus improving general running ability. The development of spring strength is of paramount concern for athletes and their coaches to improve performance in running as it impacts speed, quickness, balance, agility and coordination, and is essential for safe directional changes, stopping and starting. Spring strength training is called plyometrics and it’s required for safe and effective running biomechanics. However few physicians understand the concepts of spring strength and plyometric training. In fact physicians commonly advise against this form of exercise as they feel it creates too much shock to the skeleton. Some fear it may even contribute to premature aging through the wear and tear theory. But running and spring training performed with a properly prepared spring mechanism and sound biomechanics do not damage joints. (Note also: research shows that people who run regularly and those who don’t run at all have the same risks of developing osteoarthritis). Spring strength improves the efficiency of walking and running. Having a finely-tuned spring mechanism acts as a shock absorber to better protect the skeleton from stress and strain and potential wear and tear, inflammation and pain. It is estimated a healthy spring mechanism can recycle from 25 – 70 percent more natural energy back into the walking and running effort.

Elastic recoil Demonstration: paper spring suspension system cuff
STEP ONE UNLOCK THE HUMAN SPRING
You can do this to your patients or You can teach them how to do it and advise them to do this every night before they go to bed and in the morning Done while watching TV or at computer Important for ladies especially
Stretch the feet for additional width for improved balance Great for neuroma Important for the ladies with high heel shoes or the men with cowboy boots
Release: Ankle Joint #1 Spring (Subtalar)
Arch Spring happens at the metatarsal cunieform joint
Release: Calf and Arch Spring
Gait evaluation at different speeds because forces become exponential from walking to running The spring may stay in tact and function fine under forces of walking but breakdown during running
STEP TWO STRENGTHEN THE HUMAN SPRING SUSPENSION SYSTEM There is no training equipment in the gym for this area Bodybuilders and their gurus ignore it Top trainers and coaches ignore it These are the landing muscles Footwear weakens this area every day
Weakness is easy to see
In most cases we will need to start with a support that keeps the heel in the safe range between supination and pronation Why am I recommending a support? Because we cannot build the muscles in this area strong enough to keep the foot in the safe range fast enough to keep them from abnormal twisting motion The foot was not meant to be in one static posture too long fatigue sets in the spring suspension system weakens and the whole process starts over again How long do they have to wear the shoes lifetime
Spring Suspension System Strength Training Move the body in directions other than front to back
Spring Suspension System Strength Training Move the body in directions other than front to back
Resistance exercises in multiple directions
Step Three SUPERCHARGE THE HUMAN SPRING PLOMETRICS RUNNING & BAREFOOT RUNNING
The forces on the human foot in running are 3 - 5 times body weight So we must train the landing muscles in these forces A gradual progression is recommended and this is best determined logically With increased speeds
STRENGTHEN THE HUMAN SPRING SUSPENSION SYSTEM What is recommended is the barefoot to bedridden approach The human spring approach is the bedridden to barefoot approach We advise our athletes to apply more force to enhance spring energy Absolute Strength Training Spring Strength Training (Plyometrics) Refraining from Spring Training leads to weakening of the spring mechanisms of the body and acceleration of the aging process
Think about running or training with a restrictive mechanism logically
Natural motion is preserved when training without restriction
TRAINING PATTERNS RUNNING FORM & TECHNIQUE POSITIVE NEUROMOTOR PATTERNS NEGATIVE NEUROMOTOR PATTERNS GENERALIZED MOVEMENT PATTERNS SPECIFIC MOVEMENT PATTERNS TRAINING INVOLVES REPEATED MOVEMENTS TO STORE PATTERNS You must reteach healthy walking You must reteach healthy running Use it or loose it
Scientists have found that people who run barefoot, or in minimal footwear, tend to avoid He el-striking, and instead land on the ball of the foot or the middle of the foot. In so doing, these runners use the architecture of the foot and leg and some clever Newtonian physics to avoid hurtful and potentially damaging impacts, equivalent to two to three times body weight, that shod heel-strikers repeatedly experience. Pe ople who don’t wear shoes when they run have an astonishingly different strike. By landing on the middle or front of the foot, barefoot runners have almost no impact collision, much less than most shod runners generate when they heel-strike. Mo st people today think barefoot running is dangerous and hurts, but actually you can run barefoot on the world’s hardest surfaces without the slightest discomfort and pain. All you need is a few calluses to avoid roughing up the skin of the foot. Further, it might be less injurious than the way some people run in shoes. Daniel E Lieberman, a professor in Harvard's new department of human evolutionary biology Our research asked how and why humans can and did run comfortably without modern running shoes. We tested and confirmed what many people knew already: that most experienced, habitually barefoot runners tend to avoid landing on the heel and instead land with a forefoot or midfoot strike. The bulk of our published research explores the collisional mechanics of different kinds of foot strikes. We show that most forefoot and some midfoot strikes (shod or barefoot) do not generate the sudden, large impact transients that occur when you heel strike (shod or barefoot). Consequently, runners who forefoot or midfoot strike do not need shoes with elevated cushioned heels to cope with these sudden, high transient forces that occur when you land on the ground. Therefore, barefoot and minimally shod people can run easily on the hardest surfaces in the world without discomfort from landing. If impact transient forces contribute to some forms of injury, then this style of running (shod or barefoot) might have some benefits, but that hypothesis remains to be tested.
The researchers from the Harvard study found that even on hard surfaces such as a steel force plate runners who forefoot strike have impact forces that are 7 times lower than shod runners who heel strike.
My experience Michael Sandler
Exercies barefoot Exercise without the spring mechanism restricted by a leather or rubber binding device Abebe Bikila Study in India with children
BANG AND TWIST WALKING VS SPRING AND ROLL WALKING
Decelerated landings Increased forces According to the Harvard University study shod landings with heel strike lead to a rapid , high imact transient about 1.5 and as much as 3 times your bodyweight depending on the speed within 50 miliseconds of striking the ground
Neutral landing Bounce forces
Accelerated landings without footwear or barefoot This kind of collision produces a very slow rise in force with no distinct impact transient. There is essentially no impact transient in a midfoot or forefoot strike The faster you run the more your strike moves from midfoot to forefoot Redommended for walking mechanics as well Keep the leg totally lose to allow the forces of the landing to be distributed equally among the 33 joints of the foot and also to allow the forces to be loaded into the spring suspension system muscles
Walking mechanics must be second toe as the axis and points towards the target Maximum force from achilles Proper rolling effect around 2nd toe axis Maximum venous return from the pumping action of the calf muscles
Gait Evaluation I have listed 10 common gait abnormalities to look for to determine if the spring mechanism is not working
85 year old patient Has a 35 year Thank Dr Goldman, Dr Klatz, Dr _____ and the team of organizers for allowing me to share with you the discoveries I have made with the amazing human spring Id like to thank you, the audience and the hard working ladies in the back who translated this lecture for the audience Gracias!
