Big League Combine – Player Selection

This article is a follow up to my most popular article of all time where I describe the athletic tests that I think should be included into a combine for baseball players.  You can read it here

Since the time I published that article I have had a lot of conversations with coaches (both strength and baseball coaches) from all over the place and I get asked what I would do with the results of these tests in two different situations:

1 – Selection of players:  How can I use these numbers to help scout players and get an idea of their ability to play at the next level

2 – Training current players: What do the results of each test tell us about what this player needs to work on in order to reach the next level.

I am going to try to answer these two questions as best I can without giving away all of my trade secrets in what is looking like a three part series.

Player selection – scouting and tryouts

The first step is to obviously run all of the players through the combine that I described in the first article.  It gives us great deal of information about a bunch of different athletic qualities rather than just straight ahead speed like the 60 yard dash does.  There would be some more tests/assessments that I would do but I will get to those later.  My reason for not including these new tests in the previous article is that they either didn’t fit the criteria of being easy to implement or they are something I didn’t think of until after I wrote that article back in the summer of 2013.  I’ve learnt a lot since then but I do stand behind all of the tests that I picked.

We have all these numbers, now what??

After you run your players through these tests you’re just left with a bunch of numbers.  The good news is that these numbers actually mean something since each test was picked based on the fact that it has some correlation to the kind of athletic ability needed to play baseball, read the original article if you don’t believe me.  While these numbers are great they just really give scouts and coaches the ability to rank players based on their athletic ability.  But since we are trying to put together a baseball team and not a track and field squad we can’t base our entire selection on these performance based tests.  You need some skill to go along with this ability.

What these tests do provide are some quantifiable and objective numbers that can be combined with the scouts subjective assessment of their ability to play baseball in order to make a better decision.  Click here to see some of the quantifiable numbers that player who have been drafted out of high school or who got signed internally can produce.

sub vs ob

Ideally we want to have players with a lot of physical ability (objective) that also have a lot of skill (subjective).  Not everyone is going to have a lot of both but if you want to play baseball at a high level you’re going to need a combination of skill and ability.

To illustrate this point I’ve created this chart to show how a player needs both skill and ability to make it to the major league level, which I have arbitrarily set at the 300 mark. 

pitching chart 2.002

Each player has both skill (green) and ability (blue) but you can’t make it to the show with just one because I have also set a limit of 200 that you can get from either skill or ability.  This means that you need to sure up your weakness in order for you to display your strength.

The two guys in the minors need to work on their respective areas of weakness to make it to the majors.  The AAA “pitcher” knows how to pitch and has a complete arsenal of pitches but just doesn’t throw hard enough to compete.  This guy needs to improve physically with a good weight training program coupled with some better rest, nutrition along with a throwing program that is going to help him throw harder.

The guy in AA needs a change up or something else to go along with the blazing fastball.  The ability to locate this fastball would be helpful too.

So who do you pick??

Do you pick the skilled player or the athlete with lots of physical ability?

Scouts and coaches every year have players that they are high on and like in regards to their make up and how they play the game.  But they are forced to pass on them because they know this player doesn’t have enough power to keep up at the highest levels.  After all you can’t teach speed and you can’t teach size, right?  I think you can.

Historically baseball teams have selected players because they have some raw athletic power and physical ability in hopes that their coaching staff can teach them how to pitch or hit.  These players are then labelled as “projects” and sometimes they work out and sometimes they don’t.

I am going to make an argument that we can go after that skilled player and train them to be better athletes.  You would think that as a strength coach I would want the super athletes but baseball is so highly dependant on skill that I think some of these guys are worth the chance of becoming a project.  Because as tough as it is to teach size and speed its not easy to teach someone how to locate a change up with movement.

This is especially true if a player shows that they have room for improvement from the physical side of things which when coupled with time and effort can allow these changes to occur.

Below is the ideal situation of a highly skilled pitcher that has been through 4 years of executing both a tailored weight training and a throwing program (long toss, weight balls, etc) that suits his needs as an athlete.  This SMART and HARD training has provided him with the ability to throw harder so that he can display his skills in the MLB.   I understand that this idea isn’t anything new but I think that it could happen more often if a player has the room for growth and is given the necessary tools and knowledge to improve.  This is where the initial testing comes into play.

pitching chart 2.001

*Disclaimer:  Even the best strength training in the world won’t turn a non-athlete into a world class baseball player.  We are looking at taking someone from good to great not taking someone from bad to great.  The great news is that a lot of teams might pass on the “good” player leaving him available.

Undersized and Underpowered???

Any player that isn’t athletic enough to play at the next level is always lacking power since it is the number #1 athletic quality needed to succeed in baseball.  If they are lacking power then they are either not producing enough speed or strength since the basic formula for power is:

FORCE x VELOCITY = POWER

This formula looks pretty cut and dry but there are different combinations of athletic ability and physical features that can produce big league power.  Some athletes rely more on the force side of the equation because they have a lot of strength and body weight.  While other use more of the lean on velocity side of things with their long limbs, big ranges of motion and their reactive strength vis stretch shortening cycles to produce whatever power they can.sanchez storman

If we look at the Blue Jays pitching staff for example two
of their brightest stars are Marcus Stroman and Aaron Sanchez.  Both of whom can throw really hard but go about it in different ways.

From this example we can determine that these two players use very different combinations of strength/force and speed/velocity to produce power in the form of throwing velocity. This means that we can look for these different combinations by studying their athletic profiles which is something that I produce based on all of the tests that I run baseball players through.race car one

This athletic profile is similar to what you would see in a
car racing video game.  These two cars are different in regards to the specific amounts of power, weight and grip they have but both are capable of going fast and winning races.

They just have car 2different strength’s and weakness’ and it really depends on how you drive the car which determines if you can take advantage of the strengths while minimizing the weakness’s.

The athletic profiles that I created below are those of what I imagined both Aaron’s and Marcus’ would have looked like when they were being scouted in high school.

I will get into some of the various tests that I would add like limb length, mobility and elastic energy but for now we can just see that there are many different athletic qualities that need to be observed.  If all we did was measure the 60 yard dash to determine athletic ability we would only really have “speed” and “elastic energy” to go off of.

Aaron Sanchez 

pitching chart 2.003

While this would be a profile of a shorter more athletic Marcus Stroman.  As you can see they are very different from one another but they both work.

Marcus Stroman

pitching chart 2.004

*I know that these profiles aren’t exact and there are many arguments that could be made but my point is to look at players with different combinations of athletic ability and how they can ultimately produce the same end result of throwing really really hard even if they don’t fit the prototypical “profile”

Next I’ll explore explore both force and velocity individually a bit more and provide some examples of further tests to see if an athlete can make some improvements in these areas.

How Big is He Now and How Big Will He Get?? – Taking Testing to the Next Level

What you will find below is a chapter from a rough draft of an e-book that I have been putting together.  The e-book will explore the subject of how we can use various athletic test’s to select and more importantly develop baseball players.   Based on my experience and the stats from my site this is a popular subject and I am very excited to get this e-book finished and out there for everyone to read.

I wanted to give everyone a “sneek peek” plus it has been a while since I have put out a new article.  There will be more previews to come I’m sure.

I hope you enjoy it and find it to be useful.  I welcome any and all feed back so that I can make the best e-book possible.

Thanks,

How Big is He Now & How Big Will He Get??

From a purely athletic point of view the #1 thing that we are looking for when selecting a baseball player is their ability to produce power.  The kind of power that we want for throwing a baseball really hard can be produced in different ways which is why tall skinny guys can throw just as hard as shorter guys with more muscle.  We explored this subject when we discussed the concept of building “Athletic Profiles” based on each athletes results of their tests.

While there are a couple of different ways of producing these high levels of power the best way to increase power in the future is to get bigger and/or stronger.   So we will look at some tests and assessment which will measure specifically how big and strong an athlete is now and how much potential they have to get bigger and/or stronger in the future.

Getting Bigger means you might grow taller and have longer limbs/levers to produce more speed.  Get heavier means you will have more mass which you can use to create more force.  Getting stronger with the right type of training means you can move your mass (body weight) and your limbs faster creating more power which can lead to faster throwing velocities.

Seeing if an athlete has some room for growth or untapped power is huge because scouts and coaches are always trying to look for potential.   If we can get them bigger and/or stronger their ability to produce more power will automatically increase.

I am going to rattle off a bunch of other tests and assessments that I would run a baseball player through when evaluating their athletic ability.  Then I’ll rant about why I think it’s important without going into a ton and ton of detail because each one can be it’s own subject for article.  You will see a full list at the bottom of all the tests which wouldn’t take more than 5 minutes if you know what your doing and have experience.

You might think that this is too many tests but as long as I can get some good information I think they are worth it.  I think that any team that is going to be investing time, energy and/or money in a player would want to get as much valuable and useful information as possible.   

My criteria of knowing if an assessment or test is worth my time and effort is if it can provide me with:

  1. Results that can predict baseball playing ability
  2. Provide clues about how to better train each athlete

Some of these tests require either some equipment or skill in implementing in order to gather the information accurately which leads to the next point.  Because some of these tests are harder to implement the results that one person gets compared to another might be slightly different and as a result these types of tests don’t get used in research which means there isn’t much data out there to compare and rank players against.

That being said these tests are still very valuable.  If you build up your own data base as an organization with some standard protocols of how you do the tests the information that you gather can be used in both selecting a player and also designing them a customized program to improve their athletic ability to play baseball.

So here are my tests to see if a player can get bigger and stronger.  Let’s start with the bigger part.

How big is he and how big is he gonna get??

If someone is going to get bigger it would be because they got taller and/or heavier.

We know height and weight are important and there’s a lot of research to back that up. But if all we do is look at these two stats then we are missing the out on a lot of information.  Height and weight are just sum totals that we see on the surface but what makes up these totals can help use determine if a player has room for growth and if their height and/or weight can be used for increased throwing velocity.

If we peel back a couple more layers and dig deeper we can get some valuable info and that’s where we get into antropometrics which is just a fancy word that measures body size and portion.  Anytime a scout or coach says someone has a “big league body” or has a “good frame” they are talking about antropometrics from a very subjective point of view.  By measuring more than just height and weight we can get some really valuable and quantifiable information that can tell us exactly where a player is today but more importantly where a player might be in a couple of years.

Let’s look at height first.

How tall are they and how tall are they gonna be??

If you want to throw a baseball really hard it helps to have the right kind of levers and taller players have this advantage.  But be careful because some of the most valuable levers for throwing velocity don’t contribute to standing height so they would be missed if this was the only test.  For example there are some studies that have looked at other throwing sports (waterpolo, handball, cricket, javelin) that have found that specific physical attributes like arm span, forearm length and shoulder width were attributed to increased throwing velocity.

Simply measuring someone’s arm span while also making note of the forearm length and shoulder girth gives you a lot of great info. While your at it you can measure hand size which is another great attribute for throwing hard and creating spin.  Look at the picture below of Pedro Martinez and his disproportionately large hands!!!

pedro's handsSince I am already measuring hand size i might as well look at the length of the individual fingers to get some finger length ratio’s   There is a research about the specific ratio between finger lengths which can indicate natural levels of testosterone.  It has something to do with the amount of testosterone the fetus receives during pregnancy.  You don’t to know anything more than higher levels testosterone are a good thing when it comes to building muscle mass as well as one’s competitiveness.  How wouldn’t want someone that’s both muscular and competitive.

finger-ratio

While we are on the topic of ratio’s there are some other’s that also provide great info.

The arm span to standing height ratio is very important especially when looking at younger athletes.  The reason for this is because the limbs typically grow first so the larger the difference between the two heights (arm span>standing height) means that this player has more room for overall growth.

This ratio along with a seated to standing height ratio gives us an idea of how old this player is biologically rather than chronologically.  Chronological age is just based on how old someone is based purely on a calendar.  Biological age on the other
hand shows us how far along someone is in their maturation process.  Its estimated that up to 45% of adolescents are either “later bloomers” or “early bloomers” compared to their chronological age.  Its also been reported that the biological age can be up to three years different than the chronological age in either direction meaning a 15 year old can look like a kid anywhere between the ages of 12 and 18 based on their development.

seated

Scouts and coaches in the past have always looked at the players parents to subjectively guess what kind of growth potential there is while also making note of things like facial hair to see where a player is in their developmental timeline.  The seated vs standing height has some research to back it up to give it a more quantifiable and educated guess.  If you have that player’s previous height at 3,6 and 12 months ago you can get an even better idea as to where this player is on their growth cycle. 

This is becomes more important as you deal with younger and younger athletes.  Considering that College teams are starting to look at players as young as freshman in high school while MLB teams can sign international players when they are 16.5 years of age this kind of information can help you find those late bloomers.  

How much do they weigh? How much are they gonna weigh?

Taking into consideration how much someone weighs is more important than most people think when it comes to baseball.  Time and time again research has shown that those with higher body weights throw harder.

A lot of young baseball players simply aren’t heavy enough to produce the kind of power needed regardless of how much speed/velocity they can pump out.  There is a point of diminishing return when it comes to increase body weight and throwing velocity and that’s when someone can’t control their mass which usually means that too much of their body weight is composed of fat rather than muscle.

So ideally we want both body weight and body fat to be within a certain range.   To measure body fat and mass you could easily get a scale that does both. 

Here are some averages of pro players that have been published in the past.

Level and/or Age

Measuring body fat with the scale is quick and easy but it’s not that accurate (hydration levels can vary your results) and it doesn’t tell you where this athlete stores their body fat which is where body fat callipers come in to play.

caliper

This is a tool that does take some learning and practice in order to master not to mention the permission to pinch someone’s body fat.  The reason why you might care about where a player stores their body fat is because it might tell you something about their hormonal profile. 

This information is based on a lot more anecdotal rather than peer-reviewed research however there are a couple of papers that back this theory.   I’ve learnt about it from Charles Poliquin who refers to your fat distribution as your bio-signature.

bio sig

Higher levels of fat on your chest and triceps for example it is thought to indicate a suboptimal ratio of estrogen to testosterone since these are two locations where women tend to have more fat then men.  Fat around your belly button is also thought to indicate higher levels of the stress hormone cortisol.  The ratio of testosterone to cortisol is one of the best markers of performance and recovery is the exercise science world.

sites

Hormone analysis through either blood or saliva is the traditional way and is a lot more accurate and expensive.

Getting a player that has a bad hormone profile could mean that there is some area for improvement because if they can sort this out they will undoubtedly add muscle mass. Players that aren’t genetically gifted to have great hormone profiles in the first place will benefit from programs that are specially tailored to their unique needs which if your team can provide them with you would see an immediate return on your investment with a  better athlete.

Better training when combined with the right mixture of sleep, nutrition, mind set and supplements (legal ones) can help shift your body from a muscle burning and fat producing machine into fat burning muscle producing machine.  Click here to learn more about testosterone, growth hormone, cortisol and insulin.

Putting it all together:

So when it comes to physical characteristics I would measure following which shouldn’t take more than 5 minutes.

  1. Standing Height
  2. Seated Height
  3. Arm Span
  4. Shoulder Width
  5. Forearm Length
  6. Hand Size
  7. Ring Finger
  8. Middle Finger
  9. Index Finger
  10. Weight
  11. Body Fat Percentage (electronic Scale)

Body Fat Distribution

  • Triceps
  • Chest
  • Abdominal (belly button)
  • Supra Illica (love handle)
  • Subscap (bottom tip of shoulder blade)
  • Thigh

Grunting Increases Velocity by 5%!!!!!!

Just a couple of days ago I was flipping back and forth between channels watching a samardcouple of great match ups of high level athletes going pricehead to head.  On one channel David Price and Jeff Samardzija where trading punches with 95+ mph fastball’s while on the other channel Rafel Nadel and David Ferrer were on centre court in Monte Carlo going toe to toe.

tennis

What I found interesting was that all four of these elite level athletes grunted when every time they either threw or hit the ball.

Grunting isn’t something that you see/hear in baseball all the time but the fact that both of these flame throwers grunted on every pitch made me think that there must be something to it.  In tennis grunting is part of the game and is the sport most people associated with grunting.

Tennis just like baseball relies heavily on velocity created through rotational power which made me think that there is something that we in the baseball world can learn and apply to our sport.

Being the baseball and exercise science nerd that I am it made me curious to see if grunting could in fact increase throwing velocity.  So I fired up the computer and starting to look on Pub Med for some academic research papers on this subject.  While I couldn’t find anything related to baseball and grunting I did find one on tennis.

The Effects of “Grunting” on Serve and Forehand Velocities in Collegiate Tennis Players – O’Connell et al. (2014) 

When I quickly read through the abstract the final sentence had me hooked with this quote:

“The velocity, force, and peak muscle activity during the tennis serve and forehand strokes are significantly enhanced when athletes are allowed to grunt”

This study had players hit forehands and serves with or without a “grunt”.  The results below clearly showed that grunting increased velocity by about 5%.

Serve Velocity (km/h) Forehand Velocity (km/h)
Grunt 160.56 136.59
Nongrunt 153.05 129.6
Difference 7.52km/h, 4.91% 6.98km/h, 5.39%

What’s interesting is that some of the subjects, who were all NCAA tennis players, didn’t actually grunt when they played tennis but still displayed a velocity increase when they were asked to grunt during the study.

What is a grunt?

In this study they described a grunt as a force full expiration of air.  In some martial arts it is known as a “kiap” or “kiai” which has been shown to increase handgrip force by 7% (Welch and Tschampl).

grip

Be sure to grunt if you have to test your grip strength for an increase of 7%!!!

This forceful expiration is thought to provide some core stability with this bracing method.  There is another method of bracing the core through forceful inhalation known as the Valsalva maneuver.  This however but has been shown to increase blood pressure and mean arterial pressure and could lead to what’s known as “weight-lifter’s” blackout, probably something you want to stay away from.  The fact that grunting allows air to escape makes it much safer.

How does grunting help?

The exact mechanisms that explains how grunting allows us to create more force is actually a little complicated and I am working on trying to understand it a little better myself.  Because of this I will directly quote the authors here for the reason why the pectoralis major and the external oblique muscles were able to create more force when grunting:

“the parallel pathways from the central command feedforward effects of the motor cortex passing through the medullary respiratory neurons, which help recruit thoracic trunk musculature.”

Sounds complicated I know.  It is basically saying that a by-product of forceful expiration (the medullary respiratory neurons part) causes more muscles in the core (thoracic trunk) to be stimulated.  There were a couple of other theories that were equally as complicated but we will just stick to this one for now.

How exactly does grunting help increase velocity?

This line from the research paper helps sum up the reason why velocity can be increased with grunting:

“Increased dynamic and static force production occurs when the trunk is in a more stable position”

When your trunk/core is more stable it allows other muscles to produce more force both dynamically (moving) or statically (stationary).  This is vital for throwing hard because we need some muscles to produce movement while others provide stationary stability to allow those moving parts to move faster.

Sometimes we need muscles to play both roles at different times of the throwing action and this quote from Kovacs et al. (2008) backs this up, in the tennis world anyways:

“Abdominal muscles accelerate and stabilize the trunk during serves.”

The muscles of the trunk for example need to fire to produce rotational power through movement (dynamic) but they also need to fire in order to produce stability (static) to allow optimal transfer of energy.  It’s this “stiffening up” of the trunk that passes the energy we have already produced from the legs, hips and trunk onto the shoulders and arms.

It seems that grunting helps provide a bit more stability.

In this study the stable trunk allowed the pectoralis major to produce more force.  The pectoralis major is as the authors put it “the primary accelerator” during the serve and forehand.  When we throw a baseball the pectoralis major is the primary muscle responsible for internal rotation of the shoulder so it’s pretty important for baseball too.  Please don’t read this and go bench press to build better “pecs”, it’s more complicated than that.

serve with grunt

Is being stiff a good thing?

Just like anything else in pitching it really comes down to timing.  There are times when you want your muscles to be stiff and strong but there are times when you want your muscles to be fast and relaxed.  If you try grunting the whole time and try to “muscle” the ball to the plate the radar gun will show a decrease in velocity.  Below is a quick little chart about the characteristics of muscles when they are contracted (aka turned on) and relaxed (aka turned off).

Contracted Relaxed
Strength Strong Weak
Speed Slow Fast
Fatigue Fast Slow

One of the real secrets to enhanced athletic performance is the ability to quickly switch between contracting and relaxing your muscles.  In fact elite level athletes can relax muscles up to 8x faster (Matveyev – 1981).  Going back and forth from contracted to relaxed muscles has been coined as the double impulse theory.

This double impulse theory has been shown to take place in sports like MMA and golf (McGill 2014&2010).  Two sports that are completely different from one another yet they share the importance of having the ability to both contract and relax muscles quickly, especially the muscles of the core.

In both cases when they look at the pattern of muscle contraction and relaxation researchers could clearly see muscles being activated at the start of the swing or punch followed by a relaxation of the muscles followed by another activation of the muscles upon impact.

IMG_0365

McGill et al. (2014) – Muscles of the core when throwing a Jab. 

The first peak is when they initiate the punch and the second peak happens upon impact.  Its that valley between the two peaks that allows for hand to move quickly.

The relaxation between muscles contractions as you can see from the chart above is what allows the muscles (and the bones they are attached too) to move quickly.  Try tensing and flexing your arm through the entire punching motion and you will see how slow your arm moves.

Another important part of the relaxation is that it is going to reduce fatigue.  Contracting your muscles takes energy and as a result causes a lot of fatigue quickly which means that you get tired in a hurry.

How it works in throwing (in my opinion)

Once the back leg has initiated the momentum towards home plate it’s time for hips and trunk to produce some rotational power.  This is when we would see the initial contraction from some of the muscles in the trunk and core.  In order to get a lot of rotational speed in the trunk we need relaxation like we discussed above but we also need some range of motion.  The importance of having some range of motion is that speed takes time to develop and if you are limited in your range of motion then you will limit your ability to produce trunk rotation speed.  We see this when you look at shoulder mobility.  We need lots of external rotation in order to build up lots of internal rotation velocity.

force for long toss

If the range is small you have less time to build up speed

This range of motion in the trunk is basically describing hip and shoulder separation.  And in this case a lack of hip mobility (abduction and internal rotation) would be your limiting factor in not giving our trunk enough time to build up world class speed.  Thoracic spine (t-spine) mobility would also be a limiting factor.

hipir RigasIHRbefore

Two ways of measuring hip internal rotation – seated and prone

*side note: too much mobility can be a bad thing too since it makes it harder to harness this power – for more info check out this great research paper from Dr. Andrew Robb*

Once your trunk has built up that speed and is now facing home plate it is time to transfer this speed and energy to the shoulder and throwing arm.  This is again where we need these muscles to contract and stiffen up so that as much energy as possible to help whip the relaxed throwing arm as fast as possible.

By the way this is when you grunt.

Hopefully you have found this information to be useful.  I know that is has made me think about more questions but my conclusion would be that grunting would definitely provide some benefit. Better yet a quieter form of exhalation so that baseball doesn’t go down this same road as tennis where I have to watch the game on mute.

The main part is making sure that the athlete knows and understands the importance of the roles that both muscle strength and muscle relaxation play in throwing.

And if you are going to implement grunting make sure you do it on every pitch so that you don’t tip off when you are throwing something off-speed.

Wanna Get Drafted Out of College? Here are the physical stats of players that did. How do you compare??

This is a follow up to an article I wrote well over a year ago called “Wanna get drafted out of high school?”.  Its purpose was to show young aspiring baseball players the kind of athletic ability that professional players between below the age of 20 have displayed in the past.

Using numbers from the same study I am going to look at the athletic ability of the players that are between the ages of 20 and 22.  This is a common age range for those players at the collegiate level who are wanting to make the next jump to professional baseball.  These numbers will provide a bench mark to compare yourself against to see if you have the kind of athletic ability that these guys are looking for.

How Fast and Strong do you need to be to grab their attention?

If you fall short send me an e-mail (Graeme.lehman@gmail.com) and we can see what kind of training program you need in order to put up these kinds of numbers.

Below you will see how athletic profile of players of all between the ages of 20 and 22 in either Cincinnati Reds, Detroit Tigers, New York Mets or Texas Rangers organizations between 2005-2010.  Its even broken down into position players and pitchers.  See below for the actual reference.

So perform these same tests and see how your performance ranks compared to these athletes that have reached the same goal you are trying to achieve.

Body Weight and Body Fat: stepping on a scale to see how heavy you are is easy enough but it would be nice to know how much of that weight is fat and how much of it is lean muscle mass.   Having a lot of body weight is a good thing because it allows you to generate more energy which you can transfer into the ball when you throw or hit.  But if that body weight is high because of fat you can’t generate the kind of speed needed to succeed in the game of baseball.

Try to find someone who is skilled using body fat calipers.  You can get them to measure your thigh, stomach and chest for body fat then plug into in the Jackson-Pollack 3 body fat formula which is the formula used in the study where I got these numbers.

10 Yard Dash: Due to the short amount of time and distance is does make it a bite harder to accurately time the 10 yard dash.  If you have access to laser gate timers then go for it.  If not use a stop watch.  If coaches can accurately measure a catcher’s pop time they can get a 10 yard dash time.  If your wondering why a 10 yard dash and not a 60 yard dash then click here to read about why acceleration is so important. https://lehmansbaseball.wordpress.com/2012/06/17/accelerate-your-game-how-to-improve-your-game-speed/

By looking at the combination of your 10 yard dash time and your body weight we can easily figure out how much energy you are creating.  Remember how I mentioned above how important body weight was in creating momentum?  If you are big and can run well then you create a lot of energy that can be used with a either a bat or ball in your hand.  Pitchers for whatever reason didn’t perform the 10 yard dash.

To calculate your speed and the amount of energy you create follow the these calculations

  1. To get Speed in terms of meters per second take the number 9.41 and divide by your 10 yard dash time.  (10 yards = 9.41 meters)
  2. Divide your body weight by 2.
  3. Take your speed number (step 1) and square it.
  4. Multiply the numbers you got from step 2 and 3 together to get your final kinetic energy factor number in Joules.

Pro-Agility: Again this test places an emphasis on short burst of acceleration, 3 of them to be exact.  The athlete must also show how well they can decelerate which takes a lot of strength and coordination.  If we apply the same the equation that we did for the ten yard dash then we can get reading on how much power is being produced with the momentum that each athete creates based on their speed and mass.  The only difference is that take the number 18.82 and have to divided the number of seconds it took you to complete the test.

pro agility

Vertical Jump: Once you get your vertical jump score in centimeters we can plug that into a formula along with your body weight in kilograms to calculate the amount of power you produce.  You will get two different scores both of which are measured in Watts which is a unit of power.  The “Peak Power” score tells you how much power you created during the take off while the “Average Mean” score is how much power you averaged for the entire jump.  They are different but both important because they have been shown to predict power numbers for hitters such as home runs and slugging percentage.

Peak Power Equation = (61.9*cm)+(36*kg)+1822

Mean Average Power = (21.2*cm)+(23*kg)-1393

300 yard shuttle: Pretty easy to set up but not much fun to do.  Set up two cones 25 yards apart.  Run to one cone and then back to the first cone to complete one round of 50 yards.  Repeat that five more times for a total of 6 in order to run 300 yards.  Rest for 5 minutes then run it again.  Take the average of the two as your score.

Hand Grip:  For this test you need to get your hands on a hand grip dynamometer.  Pun intended.  Ideally it is made from the good people at Jamar because that is the brand they used in this study.

Long Toss – Part 3 – How Stressful is Long-Toss on the Arm???

This article is going to focus on what’s known as the kinetics which looks at how fast body parts are moving and how much force is being produced whereas part 2 focused on the kinematics.  Studies that look at the kinetics are important because they give us some great information that is hard to get.  Almost anyone with a camera can look at their own unique kinematics but we know that throwing a baseball is a lot more than just what someone looks like in these freeze frames.

Seeing how fast you’re moving and how much force you’re both producing and absorbing is a little more complicated.  Its a lot more expensive too.  That’s why we rely on the exercise science labs of the world which have both the expertise and the equipment.  They can measure things like rotational velocity of a joint or the amount of torque being applied at the shoulder.

The two labs were I am drawing my information from for this article are associatedjobe
with either Dr. Frank Jobe and Dr. James Andrews.  Baseball’s two most famous surgeons.  Since these studies come from these labs it’s easy to understand why they are mostly focused on exploring long-toss from an injury prevention and rehabilitation scopes rather than the performance enhancement.  Pretty much every study on long-toss out there is focused rehabilitation which is where we got this whole 120 feet max distance stuff from.  

As a performance enhancement coach this kind of information is worth its weight in gold even if its focus is looking at injuries.  Any time I select an exercise I have to look at it from a Risk vs. Reward point of view.  These studies won’t tell us much about the kind of reward (mph’s on the mound) we can get but they can let us know how much torque and force is happening at the elbow and shoulder (risk).

Before get going I want to point put that I have been learning a lot lately from Kyle Boddy’s Driveline’s blog with Dr. Buffi’s guest post’s.  Dr. Buffi discusses the short comings of inverse dynamics which is how this and most studies have computed kinetics.  It’s some pretty complicated stuff and I look forward to understanding it better in the future.  For now I am going to go with the numbers and stats from these published studies.  The good news is that even if the numbers aren’t completely accurate it is the method that they used for both long toss and pitching so at least we are comparing apples to apples here.

What’s Faster?  Pitching or Long-Toss?

I’m not talking ball velocity here but rather the velocities that happen at various joints of the body.

There are plenty of studies that show a direct correlation between how fast body parts (trunk & shoulder rotation) are moving and the velocity of the ball.  However the correlation however is not 100%. You don’t have to be moving as fast if you have a lot of body weight behind you creating momentum. 

The way they measure speed however is not in MPH’s but rather ˚/s (degrees per second).  Rotating your hips from facing third base to home plate would be 90˚ and if it took your 2 seconds you would be rotating your hips at a rate of 45 degrees per second.  This isn’t very fast at all but it paints a nice picture.

The table below again is from the Fleisig and Andrews study that I went into great detail with in part 2. Everything is measured ˚/s and the the column on the far right that’s labelled (% of pitch) looks at the ˚/s  compared to pitching.  So anything above 100 would mean that the joint is moving faster during max distance long-toss than it was when pitching.

While everything is faster when long-tossing the only one that was not seen as being significantly different between pitching and long-toss was shoulder internal rotation speed. 

Let’s look at each one in more detail.

Pelvis and trunk rotational angular velocity:  This describes how fast these two segments rotate.  They would place a marker on both hips and connect them to make an imaginary line.  This allows them to calculate how fast the hips rotate and they would do the same with the shoulders.

As you can see the shoulders rotate a lot faster than the hips do but that is how pitching works.  The legs and hips do the heavy lifting to get the momentum going so that things can move faster and faster as we move up the chain.  They didn’t say exactly at which point of the delivery the hips and trunk reached their peak velocity but if you want any hope of throwing hard you better make sure the hips go before the shoulders.

Shoulder internal rotation: this is the bio-mechanical stat we hear the most about because it is the fastest movement in any sport on earth.  The arm bone (humerus) rotates internally within the shoulder socket (glenoid fossa of the scapula) at an alarming rate.  Having the ability to really externally rotate your arm gives you a bigger range of motion that is needed to build up to this kind of speed.

Elbow extension velocity: as you rotate your entire body around your elbow goes from being bent at around 90˚ when the front foot hits the ground and then starts to straighten out as you release the ball and being your follow through. Pretend you’re doing a really, really fast triceps press down.  This rapid extension places a lot of stress on the biceps muscle since its job is to help control this rapid extension so that your elbow doesn’t come apart every time you throw.  

How much force/torque????

When studies look at the amount of force (aka torque) that happens when we throw a baseball they normally focus on the elbow and the shoulder since these are the two most injury prone areas.  

The point in the delivery that produces the highest level of force/torque is when the arm is cocked back which occurs when the shoulder is maximally externally rotated.  Its this position that is hardest on both the ulnar collateral ligament (UCL) which can lean to Tommy John surgery as well as the anterior capsule of the shoulder which can lead to a superior labral anterior-to-posterior (SLAP) tear.

The force that we are most concerned with are elbow varus torque and shoulder internal rotation torque which we can see below.

varus force

This doctor above is performing an elbow varus force test which is used to check the UCL integrity.

shoulder ir

This doctor here is applying some torque shoulder internal rotation torque by pulling his right arm and the players right wrist towards the doctor’s body causing more internal rotation. This is a position can be risky since your throwing arm has less internal rotation compared to your non-throwing arm.  If you have ever done the sleeper stretch then you know what shoulder internal rotation torque feels like. THis risky position plus too much force is the reason why some experts don’t like this stretch and if you do perform this stretch it is done with very little force.

sleeper

Pushing too hard with your left hand in this case would be increasing the “force” which in turn would be increasing the “torque” shown in this nice diagram below.

Efficient vs. Inefficient Throwing

The point of having “good” mechanics is that it allows you to produce the kind of force and torque needed to throw a baseball really hard.  And the harder you throw the more force you’re going to need to both produce and absorb.  This is just the cost of doing business.

The thing we don’t want to have happen is when we have more torque on the arm without seeing any increases in velocity.  This is a bad trade off and this type of throwing would be labeled as inefficient.  If you could throw harder while having less torque on the arm that would be called efficient throwing.

The throwing velocities between long-toss and pitching weren’t significantly different from one another and the chart below is going to show how much force is happening at the elbow (varus torque) and shoulder (internal rotation torque) when the arm is cocked back.

long toss kinetics.004

I haven’t touched on the throws from other distances (120 &180 ft) but I wanted to add them here to give more context.  All of the throws allowed for a crow hop except for the mound.

Since velocity was pretty much the same at all of the distances the most efficient throwing is the one that has the least amount of stress.  And in this study it was that magical 120 foot distance that so many MLB teams are fans of restricting their players to going.

What about the mound and the crow hop?

The two biggest differences between long-toss and pitching are how they create momentum.  Pitching uses the mound and long-toss uses the crow hop. In order to get a better idea of how each of these contributes to the kinetics of the arm and shoulder we need to look at them separately.

This is where I wanted to touch on this other study from Slenker et al. (2014) because they measured throwing from 60 feet 6 inches with and without a mound.

They also threw from 90,120 & 150 but not max distance which is why I didn’t look at this study as much.  They were only allowed to crow hop on the 120&150 foot throws and were instructed to throw “hard, on a horizontal line”.

This gives us one throw from a mound, two throws from flat ground without a crow hop (60’6″ & 90′) and finally two flat ground throws with a crow hop (120’&150′).

The subjects in this study were on average 23 years old, 6 feet tall and weighed 183lbs.  Of the 29 subjects there was one player from minor’s (A ball) , 3 players from a local club team and 25 college players from 3 different colleges.  The main thing here is that even with a pro ball guy the average velocity off the mound was only 33 m/s which is about 74mph.

Even with this lower velocity there are still some good take aways from this study. The main one being throwing efficiency which we can see with the following three charts.

long toss kinetics 2.003

long toss kinetics 2.004 long toss kinetics 2.002

Again that 120 foot mark is the safest but when you take velocity into account it is not the most efficient.

In fact the loads on the elbow and shoulder were not significantly different between mound pitching and any of the distances from flat ground. Interestingly flat ground throwing from 60’6″ was one of the most inefficient.

The authors went so far as to say:

This illustrates the mechanical advantage and increased efficiency of throwing from a mound, implying that it might be protective for players to start throwing from a mound or incline earlier on during the rehabilitation process.

This is a huge statement since we have always been blaming the mound and its slope for arm problems.  Maybe we need to be going back to higher mounds in order to reduce the stress on the arm?

Could this be the reason why we didn’t see as many arm injuries before 1969 when they changed the mound height to restrict it to 10 inches.  The previous rule was that it was limited to a height of 15 inches but there are reports of some mounds being as high as 20 inches.

We have this guy to thank for lowering the mound after arguably the most dominating season ever in 1968.

I think the use of mounds of varying slopes could be used as a form of training much like under and over weight baseballs.  Over speed training at its best – more of this to follow in the final part of this series.

When looking at the velocities the throws with the crow hop were also slower compared to throwing from the mound which wasn’t the case in the Fleisig study. Compared to the results from throwing off the mound the throws at 120 feet were 79% of the mound velocity while the stress at the elbow and shoulder were both 82% of what was seen on the mound.  At 150 feet the velocity was only 70% on the mound velocity while the elbow and shoulder stress was 88 and 91% respectively.

Of the two distances in this study the 120 ft throws were more efficient.

Here is what the authors had to say about the use of a crow hop:

The use of the entire body, or kinetic chain, with a crow hop while throwing on flat ground appears to be less stressful on the upper extremity and should be emphasized of even the shortest rehabilitation throws.

We are getting closer and closer to bottom of this long-toss subject.  But every time I find an answer it leads to a couple of more questions.

The next part will look at some distance and velocity correlations to see if throwing farther actually means you can throw faster.  This will then be followed up by an article where I try to sum everything up and provide some useful tips on how and when to apply long-toss.

Thanks for reading.
