Introduction to Neural Training for Athletics: Focus on Baseball


I've been sitting here for about an hour racking my brain thinking about baseball.  It is THE season now and it's all over ESPN, so like the flu, I was bound to catch BASEBALL FEVER sooner or later.

Anyway, as I move through my studies of the body, I have made my way through the field of biomechanics and now have landed at HOME BASE (pardon the pun) of THE NERVOUS SYSTEM.

Thanks for a pioneering group of PT's at SOMA SIMPLE, I have been truly enlightened. My realization:

THE BRAIN RUNS EVERYTHING IN THE BODY. You can live without many body parts and organs but life will cease instantly with no brain. 



As I look at the field of baseball, I see that most to all of the focus is on the strengthening and conditioning of muscles and joints.  Some coaches have even focused on the now very popular FASCIA and it's many wonderments. Anatomy trains has a foothold on many trainers and coaches now. It's fine to be interested in it but guess what....THE BRAIN RUNS EVERYTHING. No matter how well you understand fascia, if you don't have the brain to facilitate the task, you are dead in the water. Sorry to break it to you!

Anyway, I was reading a great article on a Belgian soccer coach by the name of Michel Bruyninckx entitled "Cracking Coaching's final frontier". In this article, the coach describes using "brain centered learning" as a way to train his players and its effects on his players.  "When Germinal Beerschot and Belgian international midfielder Faris Haroun came to work with Bruyninckx, he could not kick the ball with his left foot. Two years later his former club Racing Genk thought he was left-footed"


According to the article "His drills start off simply but become increasingly more complicated to challenge players' focus and maintain their concentration. Sometimes players train in bare feet to make them more "sensorially" aware; at other times they would play simple maths games while doing physical conditioning work."
Wow! A sports coach who is having success with focusing his training on the brain. I HAD to learn more. 

WHAT DOES THIS HAVE TO DO WITH BASEBALL? 
Well, it has everything to do with baseball or any other sport for that matter. As I mentioned before, the brain runs the show and when we take a complicated action like pitching, we MUST figure that into the equation. Its not just muscles, fascia and bones! 
Current USC baseball pitching coach Tom House has written a great book on pitching called " Arm Action, Arm Path, and the Perfect Pitch: Building a million dollar arm"
 and in the first chapter of the book, he discusses what he calls "Timing of the RDRBI Mechanics Variables with the Progression of Critical Events in a Pitchers Delivery". He cites 3 functions of optimal kinematic/kinetic efficiency in a pitchers delivery being: 
A. Timing
B. The RDRBI Bio-mechanical variables with
C. The proper sequencing of critical events. 





I'd like to focus on TIMING. I realize that there some disagreements with Coach House's sequencing but  I will leave that for another time. Any comments to that can be directed to him. :)


TIMING AND PERCEPTION IN BASEBALL:


As we look towards the skill of baseball, it is easy to break down component parts of the full movement from Set-up to the Follow-through. According to Coach House, there are particular points in time WITHIN the sequence of events that need to occur in a very narrow window of time. These numbers are for elite baseball players and will probably modulate given age and competitive level but they will most not likely deviate too much. However, our sense of "time" and "timing" in sports is integral to our success. In a complex action, like pitching, our brain and body have to be tuned into time or COORDINATED. This "time sense" of course is subconscious, but this should not downplay its importance. 


In a task, there is an inherent rhythm to the movements kept in step by our brain. If that sense of timing is off, then no matter what sequencing we use, it will not be as efficient and more than likely not as effective. This matter of timing is critical in both learning and performing. 


NEUROSCIENCE MEETS SPORTS


Science is now telling us that there are neurons devoted to the sensing of time which are located in the prefrontal cortex and striatum. In an article entitled "Time Keeping Brain Neurons Discovered"  based on the journal paper "Neural representation of time in cortico-basal ganglia circuits" , it suggests that part of the brain actually time stamps tasks that didn't require a specific time requirement; and that the task had dominant peaks in latencies at 100 milliseconds, 110 miliseconds, 150 milliseconds, etc after the initiation of a "go" signal. Interestingly, the neurons that are located in the prefrontal cortex and striatum also play important roles in movement, thought control and learning. 


WHAT!??!?!?!? Is is possible there are subtle peaks times in the brain for optimal learning, thought control and movement??????


BUT WAIT...THERE'S MORE.....


In a study in the Journal of Neuroscience, the researchers found that PERCEPTION has 'on' and 'off' periods where attention is a at its greatest. According to the article, "Timewarp: How your brain creates the 4th Dimension"  "[Prof] VanRullen examined another neural function, called near-threshold luminance detection. He exposed his subjects to flashes of light barely bright enough to see, and found that the likelihood of them noticing the light depended on the phase of another wave in the front of the brain, which rises and falls about 7 times per second. It turned out that subjects were more likely to detect the flash when the wave was near its trough, and miss it when the wave was near its peak."


WHERE IS THIS GOING....


Ok, I know some of the above info was a little dense BUT I am getting to what it has to do with baseball and sports in general. 



As we teach our athletes, students and musicians a skill, it is important for us to recognize that we can access the brain directly to accelerate learning. For instance, Dr. Luke Jones from the University of Manchester discovered that performance of certain tasks could be improved up to 20 percent by causing the internal clock of the brain to speed up artificially by using 10 seconds of clicks (about 5 clicks per second) to stimulate neurons in the brain. TWENTY PERCENT!?!?!?

The theory behind it is that if you accelerate peoples subjective time, "they really seem to have more time to process things," according to Dr. John Wearden, a mentor of Dr. Jones. That's the feeling of the ZONE when everything slows down and you can see things almost moving in slow motion. 

The implications in both learning skills and performance are enormous with the knowledge that we can directly affect the brain through something as simple as clicks on a metronome to improve performance. 

ARE THERE OTHER WAYS TO TWEAK THE BRAIN TO IMPROVE PERFORMANCE? 

Of course! The "Timewarp" article says that  "Edward Large, a neuroscientist at Florida Atlantic University at Boca Raton, has found that rhythmic sounds (like that found in music) can entrain gamma brain waves, causing the beginning of each sound to be accompanied by a burst of several especially strong wave peaks. The click train may entrain other types of brain waves too - perhaps those that correspond to the discrete snapshots in our perceptions. 

VanRullen and Jones agree that this may be the answer. "When you have faster oscillations, you have more snapshots per second," says VanRullen. "You may be more efficient at particular cognitive tasks, and because there are more snapshots in a given time, it may seem to last for longer.  If this theory is correct, the click train is literally resetting the brain's frame-capture rate.



SHOTGUN TECHNIQUE: 


1) Find an online metronome or download something to your smart phone. I have an app called Tempo on my iphone.
2) Set the metronome to about 250 beats per minute (bpm) in 4/4 time using the quarter note as the beat.
3) Try not to have any distractions on music. The rhythm and tempo of the music will affect the experiment. 
4) Compose of 2 sets of of 10 arithmetic problems. They should be all addition, subtraction, multiplication, division, etc. Try not to mix. 
5) Time yourself on how long it takes you to complete the first set
6) With a stopwatch listen to your metronome for 10 seconds at 250 bpm. 
5) Immediately time yourself doing set #2 of the arithmetic problems. 


Where you better on the second set? 


Could this be used when you doing other skill builidng? 


CONCLUSION


Myelination of a neuron
We know that the brain controls everything, so when we can start to understand and accept that, it opens up a whole new world to training like Coach Bruyninckx did. With the "brain centered training" we know that all skills are learned in a progression. When one step of that progression is weak, we will see a breakdown at SOME point of the complete skill. As we begin skills, we learn them in a slower approach and then begin to tweak variables like speed, distance and time. As the brain becomes comfortable with the one step of the skill, an athlete, or whoever, can start to layer and fine tune that step ("myelination")  which will create a natural transition to the next step. Until all steps are learned in an integrated fashion to produce something like an effective and efficient baseball pitch.  


OBVIOUSLY, we cannot stop focusing on the biomechanics, muscle strengthening, fascial connections, etc that is associated with sports. They have their place. Knowing joint positions and muscular eccentric and concentric movements helps us to understand the the positions and snap shots of the task; however, what is important is what is "controlling the puppet strings". 

THE BRAIN. THE BRAIN. THE BRAIN. 


If team, skills and strength coaches recognize this, their results could improve 10-20 percent! Hmmm....I wonder if that's the difference between winning and losing a championship game? You tell me!!!


Thoughts? I'd love to hear them!


Have a great day!

Dermoneuromodulation - based Training Introduction and Short Video


Recently, I have become quite enamored with the NERVOUS SYSTEM. I mean, let's face it: IT'S THE CONTROL CENTER OF THE BODY.

The brain controls everything and is supplied with information via the nerves. It controls everything from our heart rate to cell proliferation to movement. When we consider working with the body in either a rehabilitative or training setting, considering the power of the nervous system would benefit both the client/patient and the trainer/therapist. Yes, we can still look at biomechanics, fascial manipulation, joint mobilization/manipulation, muscle action, etc; however, let's not lose track of what rules what. After all, the brain is king.

A fantastic Physical Therapist by the name of Diane Jacobs in Canada has created an amazing technique called Dermoneuromodulation. Here's a short excerpt from her manual:


The DNM system takes into account cutaneous nerves. The treatment rationale includes providing the nervous system with novel stimuli to assist it to function more easily and economically. Ordinary mechanical pain (from movement deficiency) becomes decreased, usually markedly. Follow up homework includes movement suggestions, but not usually any “exercise” as such. This approach is consistent with neurodynamic theory and pain theory.

Working with DNM and Applied Functional Science based functional training has provided me with an even more effective tool bag to work from. Below is a short video demonstrating the union of DNM and AFS Functional Training

I'd love to hear your thoughts. Send comments and questions to will@3doptimalperformance.com

All the best!

How to save your throwing arm from injury




Recently, I have had to deal with a few injuries related to throwing with my athletes that has also been concurrent with a rise of throwing injuries of a few professional athletes like Stephen Strasburg and Brett Favre.

Some of these injuries are not serious and the athlete can continue playing but others, like Strasburg, unfortunately, ended their seasons prematurely.

What do all of these have in common?

The short answer was that there was more than likely a breakdown somewhere in the kinetic chain that caused the body's tissues to be overexerted in a compensation that lead to the injury. That's the easy answer. The bigger question is WHERE in the kinetic chain was there a breakdown?


THROWING BASICS 101

When we look at throwing in any sport, we see a VERY complex skill. It requires the full body to be completely coordinated to achieve a efficient and injury free motion. This means that the from the big toe up to the top of the head, everything must be in working order and orderly working.

Proper joint motion must occur at the right time, place and speed so that the muscles and connective tissue that are attached can ECCENTRICALLY LOAD so that they can create the CONCENTRIC UNLOAD/EXPLODE which results in the throw.

When there a glitch in the process somewhere, we get an overloaded compensation somwhere else in the body that leads to an injury. For Straburg and Favre, it's focusing in on their elbows. For other throwers, it can go into places like the shoulder and lower back. It just depends on the person.


The question is now HOW DO WE TRAIN AND CONDITION FOR THE SKILL OF THROWING FOR POWER AND ACCURACY AS WELL AS FOR INJURY PREVENTION?

The process lies within Applied Functional Athletic Development design. In my other post 5 WAYS TO PREPARE YOUR ATHLETE FOR SUCCESS, I outlined the process focusing on the foot and ankle, but the same process applies for skill of throwing to develop an proficient injury free motion. It is:

1) Functional Prep
2) Fundamental Movement
3) Complex Movement
4) Skill (Throwing, in this case)

A lot of times, people tend to skip the one step or another and when that happens, we can get SOME results but not as comprehensive as is possible using the 4 step process.

In the next blog post, we will go over the Fundamental Preparation that everyone who is starting to throw, throwing or maybe post rehab should do. We'll also do some investigations into some of the elbow injuries that throwers suffer from. There are already posts on Rotator Cuff impingement  and Shoulder Instability.

Please send any questions or comments to Will@3doptimalperformance.com.

Thanks,

Introduction to 3-D Foot/Ankle Complex

PLEASE SIGN UP FOR MY NEWSLETTER "MOVEMENT MATTERS" AS WELL!!!


Since I started this blog, I have wanted to write about the miracle of the Foot/Ankle Complex but hesitated every time as it is such a complex part of the body that deserves a lot of attention. I will admit that I spent over a year of intense study on the foot and ankle and still am at the beginning stages of understanding the comnplexity of the foot. However, there is a simplicity to the foot that makes it very understandable and approachable.

In this post, I will go into the SIMPLE SIDE of the 3-D Functional  Anatomy of the Foot and Ankle as well as the Chain Reaction Biomechanics.
