Research from the best minds in the automotive safety industry  all agree, the circumference of the neck changes the way it reacts to forces applied to that area.
The former Congressional appointed Chairman of the Head  and Neck Committee put together a study on concussions and found: " Stronger necks reduce head acceleration, deltaV, and displacement. Even relatively small reductions in deltaV have a large effect on head injury criterion that may reduce concussion risks because changes in deltaV change head injury criterion through the 4th power."
Test dummies are used to simulate a human in a collision whether it is by automobile or playing sports.
spring1

How do they simulate neck strength in humans?

They change the size of the spring on the test dummies. Small to replicate a child’s neck circumference.  Medium size for female adults and large for adult males.
spring2
To simulate an athlete’s neck you have to go one step further.  The athlete’s neck is simulated by the largest and most stiff spring on a crash dummy in order to replicate the kinematics of a collision accurately.
spring3

The replicated athletic neck is more resistant to change than the mock-up normal population neck.  It  deforms less then all the simulated necks.
spring4

This is true for crash test dummies; is it not true for athletes playing sports that include collisions?
By increasing the circumference of our athlete’s necks the same result should occur. Less deformation of the cervical spine.
spring5
If this is good for test dummies, it should be good for America’s athletes risking concussion during sports. It will certainly lowers the subconcussive forces.

Project Neck Case Study Eight Week Results

Project Neck Case Study Eight Week Results

Eight Weeks Of Training On The Pendulum 5 Way Head And Neck Machine
Ralph Cornwell is a Ph.D. candidate in health promotion/human performance at Virginia Polytechnic Institute and State University. Prior to pursuing his Doctoral Degree he was a collegiate strength coach

Ralph finished a pilot study on head and neck training.  The purpose is building a training model for force dissipation by increasing the circumference of the head and neck musculature.  Dissipation of force from contact will lower concussive forces and protect the athlete during play.

Most Improvement in 8 weeks

4 inch circumference increase in upper neck,
3 3/4 inch circumference change in lower neck
53. 5 pound increase in head and  neck extension
49.5 pound increase in flexion
140 lb increase in parallel grip row
261 lb increase in levator scapula/ shoulder girdle elevation barbell movement
describe the image
Least  Improvement in 8 weeks

1.5 inch increase in circumference upper neck
2.5 inch increase in circumference in lower neck
125 pound increase in parallel grip row
47.5 pound increase in neck extension
44 pound increase in head and neck flexion
215 pound increase in levator scapula/ shoulder girdle elevation barbell movement



Keep in mind, the speed of movement used was 3-4 second concentric 4-5 second eccentric, there was a pause in the contracted position of 1 second or the rep was not counted.  Over the weeks of the study the form became better and the weight increases continued steadily without compromising the strictest of technique required.

Students participate in study to lower concussive and subconcussive forces

Every 20 minutes, a different young man enters a small room in Elon University’s Koury Athletic Center looking energetic, and 20 minutes later the same man exits the room dripping and red-faced. These students aren’t shaping their calves on treadmills or curling their biceps – they’re strengthening their necks.
Each Monday, Wednesday and Friday for the past four weeks, 11 students have been visiting this little room, getting their necks measured and pumping iron with the part of the body few incorporate into their exercise routine. The students are subjects of Ralph Cornwell’s study, “Project Neck,” which researches the effects of consistent neck conditioning, with the goal of preventing damage from concussions.
Cornwell, a Ph.D. candidate in health promotion/human performance at Virginia Polytechnic Institute and State University, is conducting what is — as far as anyone knows — the only study aimed at preventing concussions, instead of fixing them after they occur. His research will also create a neck-strengthening protocol to which Cornwell hopes strength and conditioning coaches will have to adhere in the future.
“This will be the culmination of (my) doctoral dissertation,” said Cornwell. He’s performing his research at Elon because he lives in Greensboro and said, “The atmosphere here is very conducive to learning and experimentation. You get better quality.”
For the dissertation, Cornwell said he will apply the laws of physics to his research’s resulting statistics, and construct a mathematical model that will show the different outcomes of concussion-inducing forces on people who followed his protocol, and those who did not. He said this is the only way to measure the differences without hitting his subjects over the head, which he’s not about to do.
The idea is that the muscles of a strengthened neck will disperse the kinetic energy of a hard force. “The stronger your neck is, the more likely it is to dissipate the energy from a blow,” said Matt Kavalek, Cornwell’s lead research assistant and a sophomore at Elon.
Stronger neck and back muscles would mean increased support, decreasing the odds of a blow jarring the brain inside the skull after a hard blow, which causes a concussion. Cornwell likened strengthened neck and back muscles to an organic “cowboy collar” used by football players for neck support.
Cornwell and Kavalek are already four weeks into the study and are seeing results in the 11 students following the strict protocol Cornwell developed. Three devices are used, two of which are still prototypical, for various exercises focusing on the muscles in the neck or back.
Kavalek said Cornwell worked with anatomists at Wake Forest University to make sure each movement of every exercise has a direct effect on a key neck or back muscle. The exercises include the “tilt,” the “nod,” “laterals,” the “shrug,” the “shrug with head turn,” the “Kelso” and the “Hise shrug.”
But before a study participant launches into his first set of head tilts, Kavalek measures the circumference of his neck, which increases as the muscles gain strength. The study uses only male Elon students, since men aged 18-24 create the best test pool for measurable neck gain, said Cornwell. Since women don’t have the same high testosterone levels as men, their necks wouldn’t get thicker if they did the exercises, and Cornwell’s study needed a physical way to measure progress.
After having his neck measured, the study participant sits in the first prototypical device, a five-way neck machine, and rests the back of his head against a cushion. “It’s the only machine where you can train the muscles in the head and the neck,” said Cornwell. The subject performs the “tilt” and tips his head backward just 25 degrees, which works only the capital muscles — the neck muscles connected to the first two vertebra of the spine — and not the back muscles.
“It’s such a subtle movement, but the back of his head will be on fire,” said Cornwell, as Kavalek counted out 12 repetitions. The subject’s neck is burning because he’s literally lifting weights with his neck. At first, every participant starts each exercise with 10 pounds, but Cornwell increases the weight in increments after the student is able to complete a set with 10 pounds, then 15, and so on.
“We needed a baseline everyone could complete,” said Cornwell. “All the movements are slow and patrolled, so no one gets hurt.” He and Kavalek spot the test subject as he moves onto the “nod,” which is a 10-degree movement forward, as if “you’re acknowledging a friend,” said Cornwell. Then the student performs “laterals,” which is the same movement but to the left and right sides instead of forward.
The next movements, also on the five-way neck machine, target the trapezius – the muscle spanning the neck, shoulders and back, and reaching all the way down to the thoracic (twelfth) vertebrae. The subject performs a “shrug,” and then a “shrug with head turn,” turning the uppermost part of the trapezius, which Cornwell explained happens naturally when you pick up something heavy in a shrug position.
Fifteen seconds after the last set of shrugs, the subject moves to the three-way row machine for the “Kelso,” which is a movement pulling the scapula together and works all the muscles in the back. It’s the movement that test subject Thomas Emery, a sophomore majoring in psychology, said is his least favorite. “You feel it everywhere in your back,” he said.
As Emery fights losing his grips on the machine’s handles during his “Kelso” set, Kavalek cheers him on. “You’re almost there. This is your best set ever. You just need to get angry.” Sweat drips from Emery’s chin as Cornwell moves him to his last movement, the “Hise shrug.” Using squat bar equipment, Emery shrugs with the weighted bar across his back, again targeting his trapezius.
At the end of his training session, Emery is out of breath, which Cornwell said is the norm for most participants. He said he thinks many assumed training one’s neck would be easy, but found out after signing up for the study that it’s not. Kavalek compares the exercises to training a bicep: “If you put (your muscles) against a load, they’re going to get stronger.”
Despite the difficulty, Emery plans to continue neck-strengthening exercises even after the study is completed in another four weeks. And it’s Cornwell’s hope that the exercises Emery and the 10 other Elon students are performing will become part of a protocol required by certifying sports organizations, and will eventually trickle down to the high school and middle school level.
“It’s not an easy protocol by any means,” Cornwell said. But, since no other protocols for preventing concussions exist – in the athletic arena or otherwise – he said, “At least (it will) give them something to go on.”

Fixed Versus Mobile

Fixed Versus Mobile


Part of activating muscle is having it.
describe the imageThe Pashby Sports Safety Award is an award presented in Canada to recognize and honor people who make sports and recreational activities safer from catastrophic injuries, which typically involve the eyes, spine or brain.  Dr. Karen Johnston MD, PHD was given the Safety Award for her outstanding work to prevent injuries, most specifically concussions.
She is also Director of the Concussion Program at the McGill Sports Medicine Clinic.
Dr. Karen Johnston says that, “The force required to concuss a fixed head is almost twice that required to concuss a mobile head”.
Mouthguard companies understand that by activating head and neck muscles at the time of impact rotation will be decreased, which will lead to less harmful movement of the brain inside the skull.
By being able to clench down hard on a mouthguard activates the head and neck muscles and stabilizes the head.
describe the imageRalph Cornwell is taking this one step further,  building bigger stronger cylinders by developing the musculature around the head, neck and thoracic spine. The developed muscles dissipate more force and ‘clenching’ on the mouthguard with a stronger head, neck and jaw augments the value of dissipation by stabilizing movement.  This further reduces the subconcussive forces involved in causing a concussion.

Strength Train for Performance and Injury Protection

Strength Train for Performance and Injury Protection
By Dan Riley, M.S.

As the science of strength training has evolved over the past 20 years, unfortunately weight room equipment has not kept pace. Most available machines are great for training a weight lifting team, or to improve athletic performance – but sports athletes need more.
Strong muscles are good shock absorbers. A strength regimen that strategically builds muscle strength in key areas of the body can provide an extra measure of injury protection on the field.
Strong neck muscles protect against concussion
Injury protection should be a priority, especially at the high school level. The place to start is adding a neck strengthening program into the exercise regimen.
When I was an NFL strength coach, neck machines and shoulder shrugging stations were available, and players were required to train these muscles at the beginning of their workout. Over time, neck “stingers” were nearly eliminated when neck development became the priority.
And with recent news of the dangers of concussion and its long-term cognitive effects, athletes should be encouraged to do all they can to protect themselves from injury.
Strong, shock-absorbing neck muscles help to minimize concussive forces, especially on the football field. Neck strength also protects soccer and baseball athletes from cumulative concussion problems, such as the repetitive impact force of heading the ball.
Thinking long term, machines should be purchased to develop total body strength in all five major body sections:
  1. Neck and traps (trapezius)
  2. Hips and legs
  3. Midsection
  4. Torso and shoulder capsule
  5. Arms
Strong shoulder muscles protect joints, tendons and ligaments
In a five-year study with Colorado Rockies baseball pitchers, the strength of the smaller muscles surrounding the shoulder capsule was tested at the beginning of each season. It was determined that if the external rotators of the rotator cuff were weak, or if there was a significant imbalance between the internal and external rotators, the incidence of a shoulder injury was extremely high during the season.
The smaller muscles surrounding the shoulder capsule are designed to protect joint integrity. These muscles include:
  • Anterior head (frontal deltoid) – front raise
  • Medial head (middle deltoid) – lateral raise
  • Posterior head (rear deltoid) – bent-over raise
  • Rotator cuff - internal rotation
  • Rotator cuff - external rotation
The rear deltoid muscle is designed to decelerate the arm in any throwing motion. Quarterbacks, softball and baseball players, javelin throwers, etc., often complain of soreness or injury in this area.
A well-designed strength program should target each of these muscle groups. Multi-joint movement will not generate maximum strength gains in each of these muscles. An isolation exercise for each of these muscles must be performed if maximum strength and protection of the shoulder capsule is the goal.
When I worked with NFL athletes, I found many who had ignored these areas of the body. Some had already been injured and many were extremely deficient in strength in the muscles surrounding the shoulder. Once these muscles groups were targeted, players responded almost immediately.
There is great value in balancing your strength program between protection and performance, but keep in mind:  The dangers aren’t just from a catastrophic injury or sudden episode. They may also be the accumulative affect of the repetitive impact forces over time.

The Ralph Cornwell Files

Three Ways To Innervate The Lower Trapezius


describe the imageRalph Cornwell is a Ph.D. candidate in health promotion/human performance at Virginia Polytechnic Institute and State University. Prior to pursuing his Doctoral Degree he was a collegiate strength coach.

Although it is one continuous muscle, the trapezius has three distinct sections: the upper, middle, and lower trapezius. It has a diamond shape, with the triangle of the upper trapezius attaching to the occipital bone at the base of the skull and spreading outward to the top of either scapula.

dip2

Beneath the middle portion is the inverted triangle of the lower trapezius, which runs diagonally on either side of the spine from the spinous processes of the middle-to-lower thoracic vertebra to the lower inside edges of the of the scapula.

The lower trapezius is positioned to pull downward and inward on the scapula toward the spine.

describe the image

It works in opposition to the upper trapezius which is the division of the muscle whose job is to elevate the scapula, or shrug the shoulders.

A strong lower trapezius is critical in the positioning of the scapula for developing a base for power in the upper torso. And is one of the areas of our anatomy that is a dissipater of kinetic energy during head collisions.

Lower Trapezius

Three Ways to innervate the lower traps

1. Scapular depression

describe the imageOn a dip bar, keep the arms straight and let the entire body lower in the direction of the force of gravity. In this phase of the movement the scapula actually elevates.

Now the arms are fixed and the lower fibers of the trapezius will have to raise the weight of your whole body.

describe the imageThis is a lot of effort for a small amount of muscle fiber to perform this movement.

2. One arm dumbbell seated overhead press

The dumbbell must be directly over the trapezius. This produces a rotary movement of the scapula; moving the inferior angle of scapula laterally and upward.

3. Use a seated row machine, such as the Pendulum 3-way row. The lifter does one set of rows with a neutral or parallel grip. This should be performed for period of 60 seconds or less to momentary concentric failure or until a repetition cannot be performed with good form. The athlete will pause at the top of each repetition retracting the scapula. This is to fatigue the larger muscles such as the rhomboids.

describe the image

With minimal rest the load is reduced by at least 40 percent, more if needed. With an underhand and wide grip, the arms are pointing at a slightly downward angle approximately 10 degrees.

This exercise has two movements. The first is similar to a Kelso Shrug. The arms do not bend and all the movement is done by scapular retraction. Once the scapula is fully contracted the athlete flexes the elbows and pulls the weight 10 to 12 inches and pauses for a second. At that moment the athlete should be envisioning depressing the scapula.

dip

The weight is then lowered under control and another repetition is then performed. The exercise is terminated when form is compromised. This movement innervates the lower most fibers of the lower trapezius.

Examination of Chris Henry's Brain

Chris Henry Had CTE Before Death, And Why That Matters So Much

There are no mentions of Iowa sports in this post, but rest assured it will affect all of football very soon.--AJ

As the football world has come to better understand the causes and effects of brain damage in its sport, three general assumptions about Chronic Traumatic Encephalopathy (CTE) started to take hold:

  • It is a result of concussions, particularly multiple concussions
  • It happens to people with long, contact-filled careers
  • Its onset happens later in life

Basically, the general consensus was that Mike Webster was the poster child for CTE.

And then Chris Henry died, and now there's evidence that blows up all three of those assumptions. And that is just about the worst news possible for the sport of football.

Star-divide

In fact, not only does Henry satisfy none of those three conditions, he doesn't even come close. Down the line:

It is a result of concussions, especially multiple concussions: If Henry ever suffered a concussion, it was news to his teams; Henry never missed a game to head injury during his career at West Virginia or Cincinnati.

It happens to people with long, contact-filled careers Chris Henry spent four years at West Virginia, then five in the NFL. But even those numbers are both somewhat inflated; Henry redshirted one of those four years at WVU, declaring for the draft after his junior year. Once in the NFL, Henry was suspended for half a year due to arrests--some of which included erratic, violent behavior. So of those nine seasons after high school, Henry was actually playing for just 7 and a half.

Further, Henry played wide receiver, one of the least contact-intensive positions in sport. Yes, Colin Sandeman can surely attest to how violent the worst hits can be for wideouts. But the repetitious, incessant helmet contact that we've been led to believe (and not unfairly) causes CTE and that linemen, linebackers, and safeties face just isn't there.

Its onset happens later in life Henry died at 26. And not only did he exhibit classic signs of CTE, his brain was already in advanced stages of decay:

Finding CTE in a current pro football player wouldn't surprise Robert Cantu, whose Boston University research group has received funding from the NFL.

"It also wouldn't surprise me that somebody as young as 26 would have it, either," Dr. Cantu said of Mr. Henry. "What would be a big surprise is if the amount of Tau protein. ... would be as excessive as it is in people who had much more lengthy careers and died at a much later age."

"It didn't look like the brain of a 26-year-old," said Dr. Omalu, a former Allegheny County pathologist who first found CTE in an autopsy of Mr. Long in September 2005.

A picture of the tissue study of Henry's frontal cortex, compared to that of a normal brain, is here. As one researcher put it, "you should never see" the red stainings evident in Henry's brain. One would expect them in an Alzheimer's patient.

The absolute worst thing that could happen to the NFL is if multiple players routinely died as a direct result of their play--that the sport had become too brutal for humanity. And not even in a sense of shortened lifespans by 10-20 years, but Jack Trice situations happening left and right. The sport would surely collapse quickly, because human life trumps all.

The next step down from life itself is quality of life, and by that we don't mean how nice your house is or how often you smile. It's how close to "normal" your body and mind are. The lasting physical tolls of football on that quality of life are as well-known as they are devastating. Gnarled fingers and fused joints abound. Earl Campbell can barely walk. The life expectancy of an NFL veteran is currently under 60. Again, well-known, and more or less accepted by everyone involved. Would you accelerate the degenerative effects of aging for a few years of glory and fortune in the league? Many men would.

Mental degeneration, however, is a different beast altogether. When the brain goes, everything goes. The stories of Webster, Terry Long, and Justin Strzelzcyk were all characterized by CTE, depression, substance abuse, violent and erratic behavior, and early, awful deaths. And those were just three guys from one franchise.

It's hard to tell right now what lasting effect a substantial football career has on today's NFL and collegiate players, mainly because CTE can only be conclusively identified during an autopsy. The former athletes who are dying today are primarily in their 60s, 70s, and 80s; they mostly played in an era that didn't involve such violent and repetitive blows to the head. This is not to say that football was ever not a nasty sport, but the players are larger and faster now than they used to be a generation or more ago. Yes, that goes the same for both hitters and hittees (new word alert), but the one thing that hasn't gotten any more suited to contact on either side is the brain.

The NFL has been getting more proactive about concussions recently, but this news puts basically every player in the league--punters and kickers can probably sleep well at night--at substantial risk for serious mental health problems down the road, regardless of whether they've ever actually suffered a concussion. That's not to definitively say that every player's brain is self-destructing, but there's really no way to tell if any of them are suffering from those disastrous effects until the symptoms begin. And by then, frankly it's too late.

The worst case scenario is eradication of the sport as we know it. That likely won't happen, although rules of contact may change substantially. To put it coldly, it depends on whether it's worth it for everyone involved. Money talks--especially when billions are on the table. What's more likely is that the NFL will be more explicit to its entering players about the significant dangers to quality of life if one pursues a life on the gridiron. How much farther they go than that will have to depend on the results of ongoing research. From what we know right now, it's not terribly inspiring.

There's an old phrase about Bernese Mountain Dogs: "3 years a young dog, 3 years a good dog, 3 years an old dog; the rest is a gift from God." This news about Chris Henry might mean career football players are something close to the same: "20 years a young man, 20 years an athletic man, 20 years an old man; the rest is a gift from God." As an avowed and diehard football fan, I hope so much that, in the face of the evidence unfolding in fron
