Virginia Tech Researcher is making Noise in the Sports Industry

 He has developed a very specific program that he says strengthens rarely used muscles in the neck and back of the head. Muscles that can be developed and keep the brain from being tossed around while playing nearly any sport.

 Dr. Cornwell has developed a very specific program that he says strengthens rarely used muscles in the neck and back of the head. Muscles that can be developed and keep the brain from being tossed around while playing nearly any sport.

Dr. Cornwell's Protocol is the only researched and evidence based contingency available to prepare athletes for the rigors of their sport.

Let's Spring Into Action And Protect Athletes

The Ralph Cornwell Files

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- The Female Study

Project Neck- The Female Study
According to a study published in the Journal of Athletic Training in 2007, female high school athletes suffered almost 40 percent more concussions than males did. It estimated that female players suffer about 29,000 concussions annually with boys suffering 21,000.

A new study to be published in the Journal of Athletic Training found that in high school soccer, girls sustained this type of head trauma 68 percent more often than boys. Female concussion rates in high school basketball were almost three times higher then boys and the girls took longer to return to play.

When there is an Epidemic in The United States we don’t just inoculate one section of the population we give the antidote to all that need it. In light of research and just common sense our female athletes need to be protected.

Because of physiological differences, women do not have to worry about getting ‘huge’ necks, but they can become very strong. The physics of kinetic energy dissipation applies to females as well as men. The female athlete can protect herself by strengthening the musculature around the cervical spine.







Their  training is not dissimilar then the men who train theirs. They train  the flexor, extensors and trapezius muscles that allow for increased neck stiffness and high performance moves on the playing field.




Project Neck- The female Study examines the changes both anatomically and morphologically, when resistance training is introduced.








The female subjects will follow the same protocol of their male counterparts used in Project Neck earlier this year.

Wrap Your Head Around This

Yesterday I posted a blog touching on the topic of “mental training”. As I read it this morning, I wanted to follow up with a quick reminder about a serious scenario athletes deal with every day. And one that needs our sincere attention now! I am happy to get the feedback from STT nation yesterday. I appreciate you asking for more info about the following topic and presentations. So here it is…
Concussions are a HUGE topic of late. Not only in Football, so let’s talk off the grid iron for a bit. Last week a women’s lacrosse player had to sit out of a playoff game because of what was reported as “concussion like symptoms.” A softball player missed a tournament because of a “concussion.” A pro baseball player came back from a lengthy time away from the game after sustaining a “concussion.” I am sure if I looked a bit further than what was right there on the TV, on the internet, or in the paper, I could find more non-Football related stories about how head trauma, concussion like symptoms, and concussions themselves are effecting teams, players, and their health. And that was just in the past week! It is time to get serious about this issue now. PLEASE!
Dr. Kevin Crutchfield, Mike Gittleson, and Ralph Cornwell have been assembled to present on this topic from several angles. As a neurologist, and former soccer player with a history of concussions, Dr. Crutchfield will be breaking down the ramifications of what actually is happening to our brains. Coach Gittleson will be demonstrating an approach and techniques that you can implement into your program to help reduce the risks associated with head, neck, and upper back traumas. Ralph Cornwell will be putting the two together as he showcases his current research before anyone else can read his results.
Interested in the inside scoop? Yes, Mr. Cornwell gave me a little information that is certainly worth sharing about his research. And here’s our quick conversation…
STT: What was the rep tempo of your testing protocol?
Mr. Cornwell: 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.
STT: How strict were the reps in regard to form? How did you progress the athletes in the study?
Mr. Cornwell: Over the weeks of the study the form became better and the weight increases continued steadily without compromising the strictest of technique required.
STT: So tell me what you saw as a max improvement? And I have to ask, what was the minimum?

Mr. Cornwell: Here it is for you. Plain and simple.
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
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

Weight Room Charts Send The Wrong Message To Athletes

5 pounds x 10= 75 pounds
225 pounds + 75 pounds = 300 pound max
Once a value is assigned to the repetition based upon the study, in this case 0.0333,  a ‘Weight Lifting Percentage Chart’ is constructed for the general population.
chart
To use the chart a weightlifter simply finds his or her maximum along the left side.  The weight to workout with is taken from the chart based on the percentage and repetitions they are asked to utilize in their workout plan.
Sample of an athletes instructions from the Coach…
Today we are going to use 75% of our maximum for 10 reps, then 85% of our maximum for 6 reps and 90% for 4 on the bench press.  The above chart tells you the weight you should be working out with based on your individual max to Get Strong.
The athlete with a 270 max chooses…
75% – 205 x 10
85% – 230 x 6
90% – 245 x 4
Exactly what these percentages really mean to the muscle tissue is a huge question.  Weight Charts can be used as guides, yet to be accurate and take into account individual differences you need to make a chart for every exercise and every individual.
Try this to explore the reasoning of many charts…
Find your one repetition maximum in a multi-joint exercise such as a free weight barbell squat or bench press.  Select a percentage such as 65%, 75% or 85% of that maximum and do as many repetitions as possible with that percentage and record your repetitions.
describe the image
Now select a ‘single-joint‘ exercise such as barbell curl and repeat the test.  Whether trained or untrained you will find you achieve fewer repetitions at the same percentage of 1RM with a single-joint movement and more repetitions with a multi-joint movement.   In other-words multi -joint and single-joint exercises have different values of a repetition.  The amount of muscle mass involved in a multi-joint exercise and the neural system alter the outcome.
If this same test is done with a large group of athletes, say a team, you will get a similar result.  You will also find a great deal of variability from athlete to athlete in the data.
bp
Try this also……
Take all your athletes who’s maximum is the same in a particular exercise.  Let’s say their maximum is 270 pounds on the bench press.  Using 75% of their max in the above chart (205), test the maximum amount of repetitions they can do.
In general, most may achieve 10 reps as indicated on the chart, but you may find an athlete who can only do 6 reps or another who can do 15.  Very normal stuff, as we all have different neurological efficiencies.
describe the imageCharts are charts, they set a course.  They give direction. Understand that they are not based on the scientific method and each athlete will be effected differently with the recommended weights and repetitions.
The best chart to hang in your weight room is the ‘Effort Chart’.  When you go to it, it says…. give a 100%  effort to any weight you choose to….. Get Strong.

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.

Project Neck Expands to Elon University

Ralph Cornwell, Jr. PhD. Candidate from Virginia Tech announced today of the expansion of his research study looking at lowering concussive and subconcussive forces with anatomical changes to the  neck, trapezius and upper back , accomplished through resistance training.

Cornwell’s research appropriately named Project Neck,  is charged with creating a protocol that an athlete can use to lower concussive and subconcussive forces. Cornwell is using state of the art Pendulum equipment from Rogers Athletic.                                                                                                                                                                                      
Project Neck expanded it’s research from Virginia Tech to Elon University, located in North Carolina. Cornwell is working in conjunction with Elon professors Dr. Eric Hall and Dr. Paul Miller of the Neuroscience Department at Elon University.




Dr. Eric Hall       Dr. Paul Miller
Project Neck is the only study looking at preventative sports medicine. Addressing the concussive and subconcussive forces before the athlete concusses. A great amount of research is  ongoing at several universities in the United States involving concussion treatment and cause and effect. Project Neck, to the best of my knowledge, is the only proactive research study examining  the effects of anatomical and morphological changes in the human body and how these changes lower those forces.

The 8 week research study will use a protocol that involves hypertrophy of the muscles of the head and neck. The protocol also addresses the trapezius and the muscles of the upper back. Cornwell is also looking for circumference changes in the upper and lower regions of the neck. Baseline measurements taken at the beginning of the research will be compared to measurements  at the completion of the study.  Strength increases in the head and neck region will also be recorded each training session. The adaptations to the head and neck will increase the stiffness level of that area making for a more resilient athlete.
Lead Research Assistant Matt Kavalek takes baseline measurements
Cornwell’s hope is to create a basic protocol that  coaches of athletes or even  parents could use to help combat what The Center of Disease Control and Prevention calls a National Concussion Epidemic. Cornwell explains, “the only way to stop concussions in athletes is to stop playing their particular sport. If we can not stop concussions then we must prepare our athletes,youth to professional, for the rigors of their sport.” The process is really a combination of the best helmets, mouth pieces and coaching technique. The variable that I believe we are overlooking is the head and neck. An athlete can still sustain a concussion even while wearing a helmet.

The stronger athlete will be better prepared for contact or collision. Subcocussive forces are also a health problem that must be addressed. The low level bumps and dings an athlete receives in any given season can be a cause for concern later in life. Research has shown that subcocussive forces can cause long term brain injuries well after the athlete stops playing competitive sports. Concussions can be caused by the accumulation of these small hits too. When we watch sporting events on television it would make sense that the extremely hard collisions  we view would be the culprit of the concussion crisis. This not the case, as further research is conducted, scientists are finding the subconcussive forces to be just as damaging as the violent collisions. The problem with subconcussive forces is this; you don’t always notice them as an athlete playing a sport or as a coach observing a practice or game.

The Centers for Disease Control and Prevention along with the National Institute of Health agree that America has a National Concussion Epidemic. These two goverment agencies are only called upon when there is a health crisis or problem with our food supply on a national level. If there were a Flu Epidemic, scientists would work towards a vaccine and begin inoculating the population with a cure. The Concussion Epidemic has been dealt with in a different manner. Researcher observe the cause of concussions and study how to best treat a concussion after the person has injured his or her brain.

Cornwell’s research takes a different approach towards the concussion epidemic. He believes we should inoculate our youth playing sports and their college and professional counterparts. Cornwell explains, ” I do not believe we are curing the concussion problem in America with any protocol designed to give the athlete the ability to lower  concussive forces. What I do believe is this, if we do nothing we are not giving our athletes any means of  resistance to concussive or subconcussive forces. If  my study helps to lower concussive forces  by 1 percent, it is a step in the right direction. If we raise the level by which subconcussive  forces can not harm the brain, this is also a step in the right direction.”

Project Neck’s protocol is time efficient, purposeful and presumed effective. The protocol can be performed in under 20 minutes twice a week. This is not a large amount of time out of an athletes day when we are concerned with brain injury.  I want this simple study to be the genius of larger research studies looking at protecting the athlete first and foremost. Researchers, athletic trainers and coaches will tell you we can do nothing to protect our athletes. If my research proves nothing at all but spurs on further research, then what harm was done? That’s what science is all about, the search for the truth.
I would like to thanks Dr. Hall and Dr. Miller for their support. I would also like to thank Elon University for allowing me to use their facilities and their generous hospitality.

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.
Dan Riley, M.S., is a strength and conditioning educator for the Memorial Hermann Sports Medicine Institute with 27 years experience as a strength trainer in the National Football League.

Brace Yourself

Brace Yourself


Brace yourself to get ready.
Only at a velocity of zero can a muscle produce its maximal force, yet its length does not change.   In training this is called an isometric contraction and techniques such as pushing or pulling on an immovable bar or against a given load on an exercise machine at a particular angle are used to Get Stronger.
contact
If you brace, tensing your musculature as hard as possible to protect yourself from a collision, the velocity of the muscle fibers is  zero as impact occurs.
As the load increases during the brace due to a force applied by another object extrinsic to the muscle, the muscle will not yield appreciably up to about 30% of the change in the load.
isometric
In other words, a muscles ability to protect itself is about 30% higher than the force it can produce isometrically. This is natures built in cellular servomechanism. When the muscle is forced to lengthen against a load it is still able to resist the movement without accelerating at a velocity that will cause injury up to a inherit point.
This value or point is about a 2% velocity increase of a muscles V max or 2 % of how a muscle could voluntarily contract as fast as possible when it is unloaded.
In humans the built in servomechanism is important. If you are jumping or walking downstairs it enables a person to withstand a sudden load quite well.  This protects the musculotendon system from being improperly stretched and injured as the initial load is raised above the maximal isometric level.
When the load is above 40-50% of the muscle strength it will elongate the musculature at a fast rate and the forces and velocity begin to rise rapidly and often dangerously. Check out the above chart.
describe the imageOne of the many advantages of neck training is once the head and neck muscles  are strong the ability to slow down the acceleration of the head by bracing during contact is enhanced dramatically. As your strength rises so does the built in cellular mechanism of force protection against sudden loads.
A great reason to Get Strong.

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
