Why You SHOULD NOT Use “Forearm” Or “Barrel” Cues In This Way…

Lower Back Explosion Extravaganza

Tweet from a #HittingTwit-ter

We have a lot to cover in this post, so this is what we’ll be discussing:

  • Here’s the problem…
  • Short anatomy lesson of the low back, and
  • What’s the answer?

Most “bad” coaching cues I see out there can work in the right circumstances, for example:

  • “Swing down” – can work for hitters who have an extreme uppercut…
  • “Sit back” – can work for hitters who are too far out front…
  • “Swing up” – can work for hitters who have an extreme down swing…

 

But Here’s the Problem…

I’ve been tracking the above swings cues for some time now, and I’ve found in a majority of cases, they seem to churn out one low back ticking time 💣 swing after another.  When I see one of these swings on Twitter, it’s like listening to grinding teeth, someone’s fat lips smacking while eating, or nails on a chalkboard.

Let me show you what I’m seeing…

Lower Back Exploding Extravaganza

Compilation of low backs exploding…

How do I know the above hitters were instructed with the coaching cues in question?

These were the hitters on proud display via the Twitter page of the above instructor’s name I blurred out!  Now, he’s not alone in this.  Many others like him are following the same blind mouse.

Btw, it wasn’t hard to find ANY of these swings…I found them in a matter of minutes.  And to be fair, not ALL this instructor’s hitters were doing this, but close to a majority.

Here’s one more clear swing example, one of my readers Shawn Bell shared after seeing the video above…

Focus on nothing else but her lower back…OUCH!

Fact: hitting cues have consequences. When we teach a hitter to take focus away from basic locomotion and gait principles, and put it squarely on manipulating the “forearms” or the “barrel”, young hitters will have a higher probability of wearing a hole in their low back than not.

“Unload your barrel not your body”…

AND,

“The forearms swing the bat. The body helps”…

…are misleading at best, and not having a clue as to what drives ALL human movement.  And these instructors routinely call this a High Level Pattern (HLP).  Sad.  All I see are low backs grinding.  To me, this is a Low Level Pattern (LLP), disastrous to young moving bodies, built on a stale straw man argument, losing sight of the forest for the trees, and chasing a sunset running east.

And most importantly, this low back ticking time 💣 IS NOT found in the REAL High Level Pattern.  I challenge you to find me at least one who does this…and if you find one, I’d love to dig into his or her history of injury.

 

Short Anatomy Lesson of the Low Back

Lordosis of the Spine

Photo courtesy: MountSinai.org

Normal lordosis of spine (natural low back curve – “neutral” spine), left hand side image.  And hyperextended lordosis (or arching) of spine, right hand side image.

Arching causes the vertebrae in the spine to push together.  This isn’t damaging by itself especially when done in global extension (think gymnast swinging forward under the bar), but adding in a little rotation over and over and over, and we have a low back ticking time 💣.

The REAL High Level Pattern (RHLP) is driven by the spinal engine.  Basic principles of locomotion and walking gait.  I would feel MUCH better reversing the two quoted coaching cues above to read…

“Unload your body not your barrel”…

AND,

“The body swings the bat. The forearm helps”…

This is a RHLP.  As Dr. Serge Gracovetsky (Physicist and Electrical Engineer), author of The Spinal Engine book says:

“The arms and legs aren’t necessary for locomotion.  They’re an enhancement.

Do you want proof to validate this statement?  Watch this… (Thanks again Shawn Bell for the giphy)

  

…The gentleman in the above video is from one of  Dr. Serge Gracovetsky’s movement experiments.  He was born WITHOUT arms and legs.  The crazy part is, if you block out his black shorts with your hand, and look at the way he moves and locomotes, you’d swear this man has legs.

The low back ticking time 💣 risk hiding in your swing can be found in using “forearm” and “barrel” focused cues.  The proof is in the almost dozen swings I found in the matter of minutes on Hitting Twitter.

And if you still don’t agree, then here’s one of my other favorite quotes from the author of Atlas Shrugged, Ayn Rand…

“You can avoid reality, but you can’t avoid the consequences of avoiding reality”.

 

So, What’s the Answer?

A safe AND effective swing.  If we’re ruining lower backs, then how effective is effective?  Here’s a clue, instead of arching the low back, what happens if we do the opposite (flexing v. extending)?

I’m glad you asked!  Think about flexing the lower back as putting space between the 5 vertebrae located there.  This keeps the body from putting a death squeeze on the squishy and lubricating material between the vertebrae (cartilage and synovial fluid).  It makes the spine SAFE for rotation.  You got it, NO MORE LOW BACK TICKING TIME 💣’s!!!

So how do we protect our hitters and build a SAFE and Effective Swing? 

Think of your pelvis like a bowl of water.  Now, imagine a “Donald Duck” butt, where you’re sticking your butt back (arching low back – Dr. Kelly Starrett in his book Becoming A Supple Leopard refers to this as “Nasty Stripper Pose”).  For the kinesiology nerds out there, this is an anterior pelvic tilt – spilling water on your toes.  This IS NOT a good pelvic position when swinging a bat or throwing a ball.

Now, doing the opposite, imagine that same bowl of pelvis water in a posterior pelvic tilt, or Pink Panther butt, think about spilling water on your heels.

I have some cues you can use with your hitters, and a couple Hitting Performance Lab resource posts to reference…

The Hollow Hold…

If you’re one of those LLP instructors, and still aren’t convinced…PLEASE, PLEASE, PLEASE for the love of God…at least strengthen your hitter’s in the Hollow Hold.  I’m tired of seeing all the low back ticking time 💣’s waiting to go off. You’ve been WARNED.

 

In Memoriam

This post is dedicated to a great friend of mine and fellow baseball coach that we lost to a brain aneurysm on Monday… (my Facebook post):

“Words cannot express my deep sadness today upon hearing of my good friend and fantastic coach Sam Flores’s passing yesterday. He had no idea he was in a fight for his life – and would lose it – driving to the hospital with his family. So young. So tragic. My family and I ran into him at Costco 4 short weeks ago where we had a brief catch up on life and a big hug…you just don’t know when someone’s time is up. Hug your loved ones today, keep them close, and realize God is in control, not us. We love you Sam, and send my BIGGEST thoughts and prayers to your family as they go through the tragic mourning of your passing. The valley lost a wonderful Father, Husband, Friend, and ultimately a brilliant Coach. RIP my good buddy you will be missed (breaks my heart to see that little kiddo of yours) 😢😢😢

Best Swing in Baseball: Here is a Method Helping Mookie Betts – And Many Others – Consistently Crush The Ball

 

In this best swing in baseball video, we’ll discuss:

  • Data and reasoning because personal opinions are seldom useful,
    Best Swing in Baseball: Mookie Betts hitting inside pitch and 'showing numbers'

    Mookie Betts (via my Twitter feed) ‘showing numbers’ at landing on inside pitch…Hitting Guru #57 “should NEVER ‘show numbers’ on inside pitch” objection based on personal opinion with ZERO data to back claim :-/

  • Anatomy Trains, The Spinal Engine, Dynamic Body, WeckMethod, Matt Nokes, Homer Bush, Aaron Miles, and numerous past and present professional hitters agree with CLS,
  • Objection #1: Increases Time to Impact because turning away from impact – twisting balloon analogy,
  • Objection #2: Hitter loses vision and tracking of the pitch – “back eye test
  • Objection #3: Not on inside pitches – hitting “belly button” catcher’s glove,
  • Can eat soup with spoon, fork, knife…but only one way is more effective. Teaching hitting is the same.  Apply human movement principles that are validated by REAL science, NOT “because-I-said-so ‘bro-science'”, and
  • The information is out there, so hitters will find it for themselves, either you will be able to take credit for teaching it or you won’t. Results don’t lie.

Still don’t believe the best ‘show numbers’?  CLICK HERE for a post I did recently titled, “Why I Teach Hitters To ‘Show Numbers’ (And Maybe You Should Too)”.

Don’t be like opinion-based Hitting Guru #57…have solid data and reasoning to back up your “opinions”.

‘Showing Numbers’ to Pitcher is a Quick Way to Solving Consistent Power Problem

 

Question: How does ‘Showing Numbers’ to the Pitcher Effect Bat Speed at Impact versus ‘NOT Showing’ them?

Aaron Judge Showing Numbers to the Pitcher

Aaron Judge (Showing Numbers), unloads a solo home run to center field on 10/17/17 to put the Yankees on the board in the 7th inning.

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze if a hitter showing their numbers to the pitcher at landing adds to or takes away from key swing performance metrics like Bat Speed at Impact, Time To Impact, and Attack Angle.  This swing experiment is revisiting two other experiments done analyzing the same thing.

 

Background Research

Since we’re REVISITING two previous swing experiments on ‘Showing Numbers’ versus NOT, here are the original posts and data to get you up to speed:

In 2016 ‘Show Numbers’ swing experiment, this was what the averaged out Zepp data looked like:

  • 5-mph INCREASE in Bat Speed at Impact with ‘Showing Numbers’,
  • 0.5-mph INCREASE in Hand Speed Max with ‘Showing Numbers’,
  • .003 second DECREASE in Time to Impact with ‘Showing Numbers’,
  • 3* INCREASE in Bat Vertical Angle at Impact with ‘Showing Numbers’, and
  • 1.5* INCREASE in Attack Angle with ‘Showing Numbers.

Now, let’s see how the Ball Exit Speed averages compare:

  • 76.02-mph BES when ‘NOT Showing Numbers’,
  • 77.32-mph BES  when ‘Showing Numbers’,
  • That’s a 1.3-mph average INCREASE when ‘Showing Numbers’, and
  • Translates between 5.2-feet to 7.8-feet of EXTRA batted ball distance – depending on if you calculate using 1-mph BES = 4-feet of distance OR 1-mph BES = 6-feet of distance.

In this experiment, if you look at the ‘NOT Showing Numbers’ swings, they were actually ‘Showing Numbers’.  In other words, the subject in the swing experiment, Preston Scott, already shows his numbers well causing a challenge to not show them.  Therefore on the ‘Showing Numbers’ swings, he showed them more.  I think that’s why we didn’t see as much of a difference in Ball Exit Speeds.

In 2014 ‘Show Numbers’ swing experiment, this was what the averaged out Zepp data looked like:

  • Bat speed for NOT showing numbers at landing: 73-mph,
  • Bat speed for showing numbers at landing: 79-mph (+6-mph),
  • Highest bat speed for NOT showing numbers at landing: 82-mph,
  • Highest bat speed for showing numbers at landing: 88-mph (+6-mph),
  • Hand speed max for NOT showing numbers was: 27-mph, and
  • Hand speed max for showing numbers was: 29-mph (+2-mph).

Between both swing experiments, we saw an average Bat Speed at Impact increase between 5 to 6-mph.  In 2016 we saw a .003 second drop in Time To Impact ‘Showing Numbers’, while in 2014 we saw a .003 increase.

The research on increasing bat or ball exit speed can be seen in the following two books on springy fascia and spinal engine mechanics:

You can also get application of previously mentioned books through the following HPL video blog posts.

  1. Miguel Cabrera and the timing of torque.
  2. Josh Donaldson v. Jose Bautista: how spine engine mechanics are amplified by Gravitational Forces, and
  3. Adrian Gonzalez: how-to naturally spring load the body.

For those versed in Anatomy, for explosive movement on the Transverse Plane (twisting), there must be a protraction of the front scapula (‘showing numbers’), and a retraction of the back Scapula (what’s often referred to as ‘Scap Row’).  Scap Rowing by itself doesn’t engage full range of springy fascia.

 

Hypothesis

Based on the above research, I’m expecting to see a dramatic bump in Bat Speed at Impact, Hand Speed Max, and possibly a reduction in Time To Impact.  I think Attack Angle and Bat Vertical Angle at Impact will remain unchanged.

 

Showing Numbers Swing Experiment Part-3

Equipment Used:

SwingAway Bryce Harper model

This is the SwingAway Bryce Harper model hitting station used for the ‘Showing Numbers’ experiment.

Setup:

  • SwingAway Bryce Harper bungy suspended ball was set equal to the landing foot, and ball height was about knee height.
  • I broke each swing down into three steps: 1) Get to landing, 2) Pause for 2-secs, and 3) Swing.  The reason for this was to better control whether I was showing numbers or not.
  • The two tests in the swing experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘Showing Numbers’ was letter ‘A’, and ‘NOT Showing Numbers’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “warm up” factors.
  • The ‘Showing Numbers’ swing shoulders were set to about 2’o’clock, if pitcher is 12’o’clock.  The ‘NOT Showing Numbers’ swing shoulders were set to about 12’o’clock.

 

Data Collected from Zepp Baseball App:

'Showing' v. 'NOT Showing' Numbers to Pitcher Zepp Numbers

Data Analysis & Conclusion

Zepp data analysis comparing the averages:

  • Bat Speed at Impact INCREASE of 3-mph ‘Showing Numbers’,
  • Hand Speed Max DECREASE of 1-mph ‘Showing Numbers’,
  • Time To Impact INCREASE of 0.014 ‘Showing Numbers’,
  • Bat Vertical Angle At Impact DECREASE of 4-degree ‘Showing Numbers’, and
  • Attack Angle INCREASE of 6-degrees ‘Showing Numbers’.

The drop from previous ‘Showing Numbers’ swing experiments was surprising, in addition to a small 1-mph drop in Hand Speed Max.  There was also a slight increase in Time To Impact.  The interesting numbers were the ones that indicate Launch Angles, both Bat Vertical Angle at Impact and Attack Angle.  We hadn’t experienced such a dramatic uptick in those in past experiments.

A couple notes…

  • The past two experiments were done in a cage, off a tee, so I could see ball flight, and maybe that had an effect on the swing metrics.
  • Some hitting coaches speak highly of Time To Impact and want to reduce at all cost, but I disagree. There’s a healthy range for that, you don’t want it too short or too long.  I’m not going to get into why here, maybe in another post.
  • To explain the dramatic increase of the barrel’s upward trajectory in ‘Showing Numbers’, I may have been getting more of a downward shoulder angle at landing.

Controversial Swing Experiment Video: What Happens To Ball Exit Speeds When We Eliminate Use Of Lower Half?

Do you consider yourself an open minded coach?  If not, then this post MAY NOT be for you.

Do you consider yourself a coach willing to try new movements before criticizing them?  If not, then this post MAY NOT be for you.

Fair WARNING…this video will make most feel uneasy because it strikes at the heart of their teaching.  I believe the quality of our lives and the success we experience in it, depends solely on the questions we’re willing to ask our-self.

In this video, the Backspin Tee Gardner Brothers (Taylor & Jarrett Interview here) recently did a small thought provoking swing experiment that looked at how much value the pelvis contributes to the swing.  Most popular hitting instructors treat the pelvis like a JoBu shrine in the movie Major League.  Don’t get me wrong, the pelvis has a role, but I disagree on the importance most put on it.

Using the Scientific Method…

 

Question

Backspin Tee Swing Experiment on Not Using Hips

Taylor Gardner doing a Jumping No Hips Swing

They looked at how much value (measured in Ball Exit Speed) the pelvis contributes to the swing by restricting its movement.

 

Background Research

Taylor read my book The Catapult Loading System: How To Train 100-Pound Hitters To Consistently Drive The Ball 300-Feet, and it got him thinking about how much the pelvis actually contributes to power compared to the shoulders?  Earlier I mentioned how much the movement of the pelvis in the swing is worshiped by so many hitting coaches.  “Fire the hips!” “Hip Thrust baby!” Sadly, the torsional forces are taken to the point of being unhealthy for a young hitter’s low back.

Consider what Charlie Weingroff, DPT, CSCS, a physical therapist and trainer in New York City said this:

“Only your thoracic spine (which consists of the 12 vertebrae in your upper and middle back) is designed to rotate significantly — about 40 degrees in each direction, according to Weingroff — when under compression. The lumbar spine (lower back) should rotate no more than about 12 degrees.”

Let me give a clue, coaches want better separation, torque, lag, etc. in their hitters right?  We see that a high level right handed hitter’s pelvis starts rotating counter-clockwise at the start of the turn, leaving the shoulders temporarily behind, this is the essence of “lag” or “torque”.  But what coaches aren’t seeing is what’s happening before the ‘hips lead the way’?  The compression and tension forces happening in the torso beforehand, to make that move possible.

If hitting coaches would do their homework on basic bio-mechanical locomotion and function of the spinal engine as a whole, then they’d find they’re missing  60-70% of the performance puzzle (as you’ll soon see), and quite possibly wearing a hole in the lower backs of their hitters.

I constantly see well intention coaches posting videos on Twitter of their young hitters savagely twisting the pelvis and low back (lumbar), in addition to the hyper-extension of the lower lumbar.  Quite frankly, it’s painful to watch.  CLICK HERE for an exercise to correct this.

Did you know there’s a much safer way to achieve those high BES numbers and more?  Some books to get you started on the right track:

By the way, Dr. Serge Gracovetsky is a Physicist and Electrical Engineer.  He said the Spinal Engine can operate in space without Gravitational Forces.  His research shows arms and legs aren’t necessary for locomotion, they’re an improvement.  Please read that sentence again because it’s important to understand locomotion.

Can explosive high level athletes perform without the aid of Gravitational Reaction Forces?  Check out the following videos:

Derek Jeter makes jump throw…

Jeter is jumping up and away from his target, taking his momentum in the opposite direction of first base. This should put him at a disadvantage, but it doesn’t hurt him too much, as you can see.

Big air motocross freestyle jumps…

Notice how these athletes use the head to control their body.  No Gravitational Reaction Forces to help here either.  But man can these athletes put a big smile on your face while watching this video!

Don’t seek the footsteps of others, seek the footsteps they sought.

 

Hypothesis

The Gardner brothers thought this mini swing experiment would show more of a minimal role of the pelvis in the swing, compared to the “pelvis worshiping” hitting coaches out there.

 

Experiment Setup Details

  • 4 different hitters (Taylor – High School level hitter College Track & Field athlete, Jarrett – professional pitcher, Rookie in pro ball, home-run record holder at Div-1 college)
  • Took Full Swings prior to experiment swings (the Control group), so they could compare to when the lower half was restricted
  • Backspin Tee used on all swings (I know, shocker!)
  • Chair used to hit ball while falling
  • Pocket Radar to measure BES
  • Used 2 judges for checks and balances
  • Goal was to eliminate use of lower half
  • Every one used the same metal bat, a Copperhead C405 34 inch, 30 ounce (-4)

 

Data Collected

Based on control swings, this graph shows average BES as % of the control swings, Highest BES as %, & Lowest BES as % of each of the four hitters. Photo courtesy: BackSpinTee.com

 

Graph shows top BES per hitter on control swings, when Stationary No Hips, when Jump Float No Hips, Falling Float No Hips, Lead Leg Only No Hips, and Avg. BES. Photo courtesy: BackSpinTee.com

 

Data Analysis & Conclusion

Small sample sizes can cause a lot of problems, so there definitely needs to be more data points to make a conclusive decision.  However, with the data we have, the fact four different hitters participated on all swing experiments, in looking at the last graph, you can see that when the lower half was restricted, Ball Exit Speeds were around two-thirds of top exit velocity of control swings (normal swings).  Think Jeter making his jump throw!  So from this small sample size, we can say the pelvis contributes about one-third to the Exit Speeds of these four hitters.

I’d love to hear your thoughts in the Comments section below.  Be nice, be respectful.

How To Use Knowledge To Help Hitters Reach Their Full Potential

(Before getting into this post, I have to pre-frame it with the fact that cuing a hitter to ‘swing down’, ‘keep barrel above hands’, and ‘get on top’ can be helpful for hitters whose barrel paths are extreme upper cuts or for non-productive fly ball outcomes.  Other than that, these cues ARE NOT conducive to scoring A LOT of runs for teams)

The objective of this post is to persuade those who disagree with the title, to see hitting through cleaner sharper glasses.

Kudos to Sean T. Plouffe on Twitter for posting the above Tweet…

Seeing this post on my Twitter news feed dang near stopped me in my tracks.

That was actually ME in the above video!

This was a two tee drill video I did a long time ago for my old site SwingSmarter.com, between 2008 and 2010.

Unfortunately for my hitters this was the Dark Ages of my teaching, when I regurgitated swinging down on the ball because it was what I was taught during my playing days.

It felt like looking back at old High School pictures when you were fat and had more craters on your face than the moon 😛 lol

Apparently, I’m not alone in ‘teaching what I was taught’ after my playing days were over…

We’ll discuss:

  • ‘That’s what he was taught’,
  • The journey that led me away from conventional wisdom, and
  • The bottom line… (how to fix)

 

‘That’s What he was Taught’…

Take this email I recently received from one of my readers, Bryan Nugent:

“Good morning,

My predicament is that over the last year or so I have been working with my son using your style  (catapult loading) from your book. My son is like a night and day difference when he doesn’t load like you point out. Some of my cue words I tell him are tuck, hide, see and drive.

  • Tuck – for his shoulder
  • Hide – his hands
  • See – keep his eye on the ball
  • Drive – hit through the baseball

Ok, now to the issue his baseball coach is trying to get him to have a different approach, stance and pretty much a different swing all together. From what we have been working on. How would I or what is the best way to approach the Coach and tell him to leave his swing alone in your opinion?”

And here was Bryan’s response after I emailed him a couple questions…

“Thank you for responding to my email. My son is 10. This past Saturday morning before our first pool play game we went back to the cage and got back to doing what we have learned from you. His results were outstanding including a solo shot that the opposing coach told him he hasn’t ever seen a 10 yr old hit the ball that far before.

The coach is young(23) just graduated from a local college where he played baseball. Not knocking him in any way but when talking to him he states ‘that’s what he was taught’ quite a bit. So maybe since this is his first time to coach young boys he is trying too hard, if that makes sense.

I did talk to him a little bit and told him I would bring him your book so he can see where we are coming from. Hopefully he will see there are 2 ways to skin a cat to get the same result. Which is to be able to get the kids to reach there full potential. Thanks again”

Thank you Bryan for sharing and for your continued support.  And yes, I asked his permission before sharing with you coaches.

 

The Journey that Lead Me Away from Conventional Wisdom

I can honestly say that I was where this young coach is when I first started teaching hitters.  And I know many of you coaches out there, if you’re being honest with yourself, can relate.

I had stopped seeking knowledge about the swing…stopped reading…stopped asking questions.  My mindset was VERY fixed.

Needless to say, I came to the realization that my hitters weren’t getting better.  At the time, my local lessons weren’t growing.  I was teaching what everyone in my area was teaching.  There was zero differentiation.  And you know what Mark Twain once said,

“When you find yourself on the side of the majority, it’s time to pause and reflect”.

It wasn’t till about 2011 that I started asking questions, and bought Jaime Cevallos’s book Positional Hitting (who’s a good friend of mine).

Then met Chas Pippitt of BaseballRebellion.com, and helped him develop an online presence in 2012.

This was a good start, but there were still A LOT of unanswered questions that I had.

You see, I found a passionate curiosity for corrective human movement science back in 2005.  I got educated by gathering a large wicker basket full of alphabet soup certifications.  In a short time, I was training athletes and non-athletes by helping them troubleshoot their mobility and stability issues to improve performance or quality of life.

This led me down a rabbit hole that went pretty deep.

When my son was born at the end of 2012, I had an epiphany after reading a couple highly influential resources.  I digested the following books over and over, using them to reverse engineer the swing from a human movement principles validated by science perspective:

 

The Bottom Line…

If you’re a young coach – or more seasoned – who still teaches swinging down on the ball, squishing the bug, and that the hips are where the power is at…I know how you can feel married to these because you’ve put a lot of time, effort, and emotion into them while coaching and/or playing.

Believe me, I felt the same way.  Looking back now, it was a form of collective wisdom brainwashing that runs rampant in baseball and softball circles.

Here’s what I found teaching young hitters to apply human movement principles that are validated by science to hitting a ball:

  • My hitters see and feel productive outcomes within a reasonably short amount of time (huge for getting them to ‘buy into’ the system),
  • The online and local lesson part of my business has increased 5-fold (the word is getting out!),
  • The coaches that learn this from me are getting the same productive results with their hitters – if not better (and their hitters are raising the eyebrows of other coaches), and
  • The best news is, the knuckleheads on social media have a VERY difficult time arguing the true science of the swing!

My recommendation is this:

  • Educate yourself like I did with previously mentioned books,
  • Question very things you teach by asking, “What don’t I know?”
  • Do swing experiments like I do to see if a hitting mechanic is inferior or superior to its counterpart (CLICK HERE for a post on how to do this), And…
  • Above-all, be big enough to swallow your pride, regardless of how many years coaching or playing, or if you had the privilege to coach or play at the highest level, and admit you may be wrong.  Because let me tell you, many are, so you’re not alone.

Rest assured, if I can change, then so can you.

Believe me, your hitters will THANK YOU.  Learning can start when ignorance admits its ignorant. You don’t know what you don’t know, right?  Well, now you do 😉

Zepp Swing Experiment Attempting To Put Value On Role Of Pelvis In Swing

Question: How Much Does Pelvis Add to Bat Speed at Impact?

According to InnerBody.com, the pelvis is a sturdy ring of bones that protects the delicate organs of the abdomino-pelvic cavity while anchoring the powerful muscles of the hip, thigh, and abdomen. Several bones unite to form the pelvis, including the sacrum, coccyx (tail bone), and the left and right coxal (hip) bones. Photo courtesy: OrthoInfo.aaos.org

Using the Zepp (Labs) Baseball app, I wanted to employ the Scientific Method to analyze how much turning the pelvis (some refer to this as the hips) adds to Bat Speed at Impact.  The ‘Front Facing Swings’ are an attempt to isolate out the role of the pelvis in the swing, so we can analyze how much the pelvis adds to swing performance.

Just a heads up, the “pelvis” and “hips” are not the same thing.  The hips are a small part of the pelvis.  However, most coaches refer to “hips” when instructing the swing, when most likely they mean “pelvis”.

 

Background Research

For those coaches with a Growth Mindset that want to find out more about the science of locomotion.  I’d recommend reading the following technical books:

If working through the weeds isn’t for you, then you can click the following HPL posts that synthesize the information contained in the previously mentioned books:

I’ve done two swing experiments revealing the role of the shoulders in the swing that tested the value of ‘Showing Numbers’ versus ‘NOT’.  These showed an average increase to Bat Speed at Impact – Showing Numbers – of between 5 to 6-mph.  In addition, one of the experiments showed an average increase to Ball Exit Speed of over 9-mph ‘Showing Numbers’! That’s between 38 to 48-feet of ADDED batted ball distance by ‘Showing Numbers’:

This Zepp swing experiment is attempting to put value on the role of the pelvis in the swing.

 

HypothesisThe Science of Hitting by Ted Williams

Ted Williams, in his book The Science Of Hitting, said the ‘hips lead the way’.  This observation is irrefutable when watching slow motion video of elite hitters.  A majority of coaches teach primarily a ‘hips only’ strategy, which I disagree with.  I feel ‘firing the hips’ is over-taught and over-valued, while the role of the shoulders is under-taught and under valued.  The objective of this experiment is to see what benefit the pelvis (or hips) add to swing performance.

I predict ‘Regular Swings’ will have a substantial increase in Bat Speed at Impact than the ‘Front Facing Swings’.

 

Performance Benefit of Pelvis Swing Experiment

Equipment Used:

Setup:

  • Yellow dimple ball feedback markers to keep starting footwork the same = bat length…I used two yellow dimple ball markers to make my stance setup consistent.  One was placed inside my back foot, close to the plate.  The other was placed one bat’s length ahead of the back marker.
  • Tee was set one baseball’s length behind the front feedback marker, and tee height was about mid-thigh
  • We stayed as consistent as we could with keeping the ball height and depth the same for most swings.
  • The two tests in the swing experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘Front Facing Swing’ was letter ‘A’, and ‘Regular Swing’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “warm up” factors.
  • The objective of ‘Front Facing Swings’ was to start the ‘belt buckle’ pointing at the pitcher, and to minimize pelvic movement.
  • Experiment Day-1 on 6/19 we completed 75 total swings (25 ‘Front Facing’ & 50 ‘Regular’).  Experiment Day-2 on 6/26 we completed 125 swings (75 ‘Front Facing’ & 50 ‘Regular’).
  • We had to break the 200 total swings into two days, with the second day coming 1 week later, because of time constraints.

 

Data Collected (Zepp Baseball App):

‘Front Facing Swings’ Days 1 & 2 side by side…

Front Facing Swing Averages

‘Front Facing Swing’ AVERAGES for the following metrics: 77-mph Bat Speed at Impact, 30-mph Hand Speed Max, 0.177-secs Time To Impact, -24.5* Bat Vertical Angle at Impact, & 3* Attack Angle.

‘Regular Swings’ Days 1 & 2 side by side…

‘Regular Swing’ AVERAGES for the following metrics: 81.5-mph Bat Speed at Impact, 33-mph Hand Speed Max, 0.130-secs Time To Impact, -28.5* Bat Vertical Angle at Impact, & 0* Attack Angle.

 

Data Analysis & Conclusion

Zepp data analysis comparing the averages of averages:

  • 4.5-mph INCREASE to Bat Speed at Impact in ‘Regular Swings’,
  • 3-mph INCREASE to Hand Speed Max in ‘Regular Swings’,
  • 0.047 DECREASE to Time To Impact in ‘Regular Swings’,
  • -4-degree DECREASE to Bat Vertical Angle at Impact in ‘Regular Swings’, and
  • -3-degree DECREASE to Attack Angle in ‘Regular Swings’.

 

Notes

  • The increase in Bat Speed at Impact and Hand Speed Max confirmed my hypothesis, and didn’t surprise me since the first piece of The Spinal Engine to interact with Gravitational Forces is the pelvis.
  • It’s also interesting to note, that you can see from the side-by-side video of the swing, that I wasn’t able to keep the “belt buckle” ‘front facing’ as much as I would have liked to on ‘Front Facing Swings’, so possibly the pelvis could have added a bit more.  I was feeling inside right knee tightness when forcing pelvis to stay facing forward.
  • The DECREASE in Time To Impact with ‘Regular Swings’ could have been due to the increased step and/or unfamiliarity with the movement, while doing ‘Front Facing Swings’.
  • In past swing experiments testing ‘Down Shoulders’ and ‘Showing Numbers’ I increased my Attack Angle – in the positive.  I think the 3-degree increase in positive Attack Angle for ‘Front Facing Swings’ was due to better execution of those elements.
  • We were testing Ball Exit Speed in the beginning but had equipment malfunction (batteries went dead).  I was too many swings in when the equipment was fixed, so we threw BES out in this experiment.  I’d love to see BES measured in a future review of this swing experiment.
  • One last thought, because my pelvis inwardly turned toward the catcher – drastically – on ‘Front Facing Swings’, we saw quite a drop-off in production.  Does this give evidence that an inward turn before the swing may be inferior to keeping the pelvis in neutral (or belt bucket facing plate)?

Little Known Way To Optimize Bat & Ball Exit Speeds By Rotating “Under Load” (not what you think)

In today’s video, you’ll learn how to fix your flat feet

…(insert record scratch sound effect)…

“Wait a cotton pickin’ minute, so you’re showing me a video on how to correct ‘flat feet’?!  How is this suppose to help my hitters?”

…Someone somewhere might be saying 😉

The above video will be a game changer for the progress of your hitters.  It may even improve bat and ball exit speeds over time.  It may even fix some of the hitting faults you’re having a challenge correcting right now.  The content in the above video will improve both the rotational effectiveness and efficiency of your hitters.

He’s a locomotion expert, and by the way – he talks really fast!  Here are a couple notes I took while watching the above video:

  1. Naudi talks about how the body doesn’t need lower leg to sprint at the highest level. Don’t believe me, CLICK HERE to watch this video of South African sprinter Oscar Pistorious who won 3 Gold Medals in the 2008 Beijing Olympic Games (about 0:45 minute mark).
  2. Relationship between pecs, lats, and glutes – anterior and posterior oblique slings, highly neglected part of training and carries a bigger influence on efficient movement (about 1:45 minute mark).
  3. Leg and knee should land as close to neutral as possible when running or walking with effective rotation.  If deviation occurs, then most likely there’s a deficiency in either the anterior and/or posterior oblique slings (about 3:05 mark).
  4. The idea of rotating “under load”. Using feedback mechanism – the resistance band – to “feed the mistake”.  Click to get WODFitters Pull Up Assist Bands on Amazon. (about the 4:45 mark).
  5. Practice functional movement patterns, walking, running, or hitting while using the feedback bands (about 8:30 mark).

 

In Application…

About point #1 above, as most of you know, I’ve been promoting a spine driven swing for the past 4+ years.  If you read Dr. Serge Gracovetsky’s book The Spinal Engine and Thomas Myers’s Anatomy Trains, then you’ll discover that the legs aren’t necessary for locomotion, they’re an enhancement.  CLICK HERE for a post on this titled, “The Swing Does Not Start From The Ground And Move Up?”

About points #2 & #3 above, some experts call this the “Serape Effect”, “Power Slings”, or Thomas Myers labels these a combination of Spiral, Functional, and Lateral fascia lines.  Hitters, both young men and women, will have a deficiency here. Since a majority of hitters DO NOT take the same amount of swings and throws from the opposite side, there will be an imbalance created that MUST be addressed.  Diversifying in other sports does help, but most likely, there MUST be correction.

About point #4 above, Naudi Aguilar uses a band that’s much longer than the one I use at home, so you may not need to wind it around the mid-section as much as he does in the above video.  For me (I’m a right handed hitter/thrower), to correct dysfunction in rotational locomotion, I wrap my band over my left shoulder, then around my middle back, and then loop the end around my left leg.  You’d do the reverse to enhance rotation for a lefty.  I put this on at least 5 days per week, and wear it for about an hour while doing my morning routine.  I’ve found the tightness in my right foot, Achilles, and inside part of my right knee almost vanished within 3-4 weeks of doing this.

Also, CLICK HERE to learn where I talk a little more about “feeding the mistake” using Reactive Neuromuscular Training, or RNT to correct ‘stepping in the bucket’.

About point #5 above, Naudi mentions rotating “under load”.  Coaches, I’d advise having hitters experiment using the feedback bands while hitting, and recommend they wear it at home too, as a recovery tool.

These bands are a great way to counter-balance the imbalanced movements baseball and softball inherently promote.  If your hitters move better, they’re perform better.  Swinging smarter by moving better.

David Weck & the WeckMethod are Turning Rotational Power Training on its Head

 

David Weck: WeckMethod RMT Club

You asked for it!

I had quite a few of my readers ask me about the WeckMethod of training by David Weck.  Btw, David is the inventor of the Bosu Ball, for those that train athletes for a living.  And the readers who kept bringing up his training referred to his new product the RMT Club (CLICK HERE to get it on Amazon), which you’ll learn more about in the above interview.

If you’ve never heard about the WeckMethod of training, and want to know what sets it apart, please CLICK HERE to view the following 35-min video.

If you’re short on time, then here’s a brief introduction to the WeckMethod of training from David Weck:

“What I do is more fundamental foundational work than specific hitting instruction.  My focus is improving systemic strength and power concentrating on Tensional Balance and Rotational Power – as well as non-dominant side training to provide a stronger foundation for sport specific skill.”

I feel like he’s onto something that most trainers ARE NOT. And it’s because he understands the foundation of locomotion.  He has a fantastic understanding of the human movement “rules”.

In my research, I fell into the following David Weck Carpool Tunnel fix video that helped get rid of the pinching in my right wrist, at the bottom of a push-up position, in about a week (I haven’t been good lately with my gymnastics wrist stretches 🙁:

Another great article I ran into in my research – and posted to social media – was an interview that Chris Holder did at BreakingMuscle.com with David Weck titled, “The Key To Speed Is In Your Spine”  There are great nuggets in there along with a few training videos.  It’s definitely worth your time.

The main video above is a Skype interview I did with David Weck that’s about 45-minutes.  A lot of great information in there that translates to hitters and HOW TO train power.  What follows are some of those talking points…

The Show Notes

  • How would you explain to a complete stranger what it is that you do? (1-min, 22-seconds)
  • DW explains Tensional Balance – relationship between suspension and transmission throughout your body, requires perfect alignment of skeleton, muscles, and connective tissue (1-min, 48-secs)
  •  When tensional balance & rotational power are dialed in, you can express more speed, control, power, etc. with LESS wear and tear on the body (3-mins, 10-secs)
  • Where did DW’s passionate curiosity into this realm of training come from? (4-mins, 20-secs)
  • DW discovered slow motion analysis while playing D3 college football – you cannot understand human movement with that slow frame by frame motion analysis, the eye in the sky does not lie…clock doesn’t lie…measuring tape doesn’t lie (6-mins, 0-secs)
  • Unmatched degree of intensity to enhancing human locomotion because of Bosu Ball success…was able to devote entire focus to seeking and finding answers. (7-mins, 23-secs)
  • Deep appreciate that locomotion is the key, developing straight ahead speed, is the key to developing the greatest rotational power (9-mins, 0-secs)
  • Human movement industry is about to be flipped on its head because of this breakthrough understand of “core” strength…the “Bracing Core” (weight room and picking up heavy objects) versus the “Coiling Core” (engaging in lateral movement – side bending and head over foot) (9-mins, 40-secs)
  • Real versus Feel coaching, “My athletes are doing something that I’m not coaching them to do”, high level athletes have an innate sense of speed and power, but coaches are trying to coach it out of them, elite athletes (like Olympic Gold Medal winning sprinter Michael Johnson) saying to do the exact opposite of what they’re doing on film!  Experts are teaching on a faulty foundation (11-mins, 40-secs)
  • DW is meeting with Marlon Byrd on getting specific with the WeckMethod exercises (14-mins, 7-secs)
  • Quick movement experiment…stand up right now and going through a throwing motion WITHOUT any side bending…how did that feel? Without side bend you’ll destroy your spine. You can train side bend. Locomotion is your foundation. (17-mins, 50-secs)
  • DW responds to the reader comment, “Is it logical to say that average kids can perform at a tier-1 level?” In context, the reader comment was to the claim that my 100-lb hitters consistently driving the ball 300-feet are standouts athletically.  Also, what makes a kid athletic? (20-mins, 10-secs)
  • DW explains how to train ipsilaterally (right shoulder-right hip) to get the “Serape Effect” or I like to call the “Springy X Pattern” (right shoulder-left hip) optimized for performance. Tighten the coil, time the sequence, and keep center of gravity to be neutral. Take clunky and make them fluid. (22-mins, 20-secs)
  • DW discusses the curse of moving the center of gravity during rotation.  Learning the axis of rotation, front/back, and side. Central control. Create a late rotate, like a whip. (25-mins, 0-secs)
  • The evolution of the spine, side bending is crucial to an S-shaped spine curve. (27-mins, 30-secs)
  • DW responds to the question, “Does sprinting, throwing, hitting start from the ground up?  Why or why not”. CLICK HERE for the HPL link I referred to in the video (33-mins, 30-secs)
  • DW talks about harmonizing the muscles with the connective tissue.  Least muscular contraction compared to the connective tissue. Muscles that are bound up, cannot relax.  Transmission of force, power equals speed.  Muscle acts like a circuit breaker. (34-mins, 0-secs)
  • DW discusses having tensional integrity between the muscles on the inside, and fascia on the outside. How integrity and connected the fascia is to muscles.  Bonds never lost body-weight transmission when he bulked up.  Strong is great, but not at a sacrifice of speed.  (37-mins, 0-secs)
  • We discuss Thomas Myers, Anatomy Trains, “finger flick” test to demonstrate the power of connective tissue over muscle contraction (38-mins, 44-secs)
  • DW responds to the question, “If you were going to prescribe 2 of your top RMT Club exercises to a baseball or softball player, what would they be?” Coiling Head Over Foot movement. Pulse of power. (39-mins, 30-secs)
  • DW top gifted books: Thomas Myers book Anatomy Trains, Jim Piersall book Fear Strikes Out: The Jim Piersall Story (44-mins, 0-secs)

Now Your Hitters Can Have Power Without Starting The Kinetic Chain At The Feet


I briefly viewed a hitting instructional video on YouTube the other day that one of my readers sent me (Thanks Joe),

…I won’t share who did the video, so as not to cause any embarrassment.

Like what was being illustrated in the video, I would say a majority of hitting instructors both online and off swear that the swing starts from the ground up.

This IS NOT what the current research shows as validated by human movement science.

Yes, Gravitational and Gravitational Reaction Forces do have their place (and we’ll get to that)…my point is, ALL human movement DOES NOT start from the ground, and work it’s way up the Kinetic Chain.

Consider this Tweet from one of my readers…

And I added the following comment…

What I have for you above, is a snippet of video about 5-minutes long, explaining where the swing starts as explained by Dr. Serge Gracovetsky, Physicist, Electrical Engineer, and founder of The Spinal Engine.

Here are some talking points that Dr. Gracovetsky mentions in the video (please WATCH video at the 2:00 minute mark to about the 7:00 minute mark):

  • There’s a lack of agreement in literature at what the function of the spine is.
  • Spine is generally believed to be a supporting column linking shoulders to pelvis…as we walk the trunk is thought to be carried passively by the legs.  Problem with this: WHY is shape of spine in form of an “S” instead of being straight? – straight column would support compressive loads better than a curved one right?
  • Consider 20-year-old male subject who has reduced arms and no legs…moves on his Ischium.
  • If it was true that legs are necessary for human locomotion, then a person with such an anatomy would not be able to walk.
  • With the bottom of the screen hidden [while the subject “walks” across the floor], it is impossible to tell that this man has no legs.
  • Locomotion was first achieved by movement of the spine, and the legs came after as an improvement, not a substitute.
  • When providing a lateral bend to a curved spine (lordosis), an axial torque is induced. The rotation of the pelvis and shoulders is driven by the spine.

And this is the basis for my The Catapult Loading System book on sale at Amazon.

So does the swing, or any human movement for that matter, start from the ground up?  In other words, are Gravitational Forces a necessity to move the Spinal Engine or merely an enhancement?

In an email conversation I had with Dr. Serge Gracovetsky a few years back, he said this about the relationship between gravity and spine engine mechanics:

The coupled motion has nothing to do with gravity. It works in space as well. It is a property of the spine or any flexible rod for that matter.  But the interaction with gravity makes interesting results which are exploited by every sport.”

Okay, since we’ve determined human movement DOES NOT start from the ground and go up the Kinetic Chain, I want to share a couple snippets from Dr. Gracovetsky about what role Gravitational Forces do play in dynamic movement…

Here’s a note about the importance of the heel strike in locomotion from Dr. Serge Gracovetsky in his book, The Spinal Engine (p. 168):

“…the compressive pulse generated at heel-strike is essential to the locomotion process.  The shape of this pulse must be very specific if maximum energy is to be transferred from the earth’s gravitational field to the rotating pelvis.”

According to Dr. Gracovetsky, while running, our heel hits the ground creating a compressive force that is equaled to NINE-times our body weight.  Gravity pulls our body down, and at heel strike, the ground pushes back in a compressive force.

This is why it has been demonstrated by Speed Coach Barry Ross that runners who dead-lift heavy weights with a low time under tension, get faster!  They’re able to push into the ground with more force, which in turn, the ground pushes back with equal and opposite force.

It’s also worth noting about the Spinal Engine while walking on sand versus solid ground…

Dr. Serge Gracovetsky offers this example in his book (pgs. 168-169),

“Running or walking on soft sand is not easy and is very tiring,  In this particular case, the energy leaks into the sand, the impact force is reduced, and the compressive pulse through the spine is attenuated [disabled] as the total energy recovered is reduced.”

The compressive force is softened by the sand, which doesn’t allow the pelvis to turn using efficient spine engine mechanics.  To maneuver, the brain has to recruit big muscles to do the work.  This is why you get a workout walking on sand…it’s powerless effort, rather than effortless power.

Does current research, that’s validated by science, say human movement starts from the ground, and travel up the Kinetic Chain?

No.

The trunk isn’t just a passive structure that is carried by the legs.  Legs are not a necessity to human movement – evidenced by the legless subject in the video – they’re an enhancement.  The Spinal Engine can work in space!  I say the legs and arms amplify the movement of the Spinal Engine.

Do Gravitational Forces play a role in human movement?

Yes!

Like Dr. Gracovetsky says, “…the interaction with gravity makes interesting results which are exploited by every sport.”

That my friends is a human movement principle that is validated by science.  Not philosophy or theory.  This is why my new book The Catapult Loading System is so powerful to hundreds of coaches and tens of thousands of hitters across the US… (just check the reviews 😉

Here is a Method That is Helping Nelson Cruz ADD Ridiculous Batted Ball Distance

 

Nelson Cruz: 'Showing Numbers'

(‘Showing Numbers’ Experiment REVISITED) 

Question: Is Increased Bat & Ball Exit Speed ALL in the Hips?

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze whether ‘Showing the Numbers’ to the pitcher is more effective than ‘NOT Showing’ them when it comes to measuring Bat and Ball Exit Speeds.

In this swing experiment, I had professional hitter of mine that I’ve been working with for a few months, Preston Scott, do the hitting.

 

Background Research

I’m revisiting an earlier experiment I did, looking into whether power was ALL in the hips.  You can CLICK HERE to read and watch the experiment findings.

Not to beat the springy fascia horse, but you can get more background information on why this swing experiment turned out like it did by reading through the following video blog posts.

  1. Miguel Cabrera and the timing of torque.
  2. Josh Donaldson v. Jose Bautista: how spine engine mechanics are amplified by Gravitational Forces, and
  3. Adrian Gonzalez: how-to naturally spring load the body.

 

Hypothesis

From the research into Anatomy Trains (Thomas Myers), The Spinal Engine (Dr. Serge Gracovetsky), and from my past swing experiment, I expect to see similar results…maybe even slightly lower numbers favoring ‘Showing Numbers’.

I say slightly lower numbers because in the first experiment I didn’t counter-balance the swings.  In other words, I took 100 consecutive swings ‘NOT Showing Numbers’ first, then took another 100 consecutive swings ‘Showing Numbers’.  This may have caused a “getting tired” or “not warmed up yet” effect, therefore biasing the experiment results.

The big UPDATES to the experiment will be:

  • Adding the measure of Ball Exit Speed,
  • Counter-balancing the swings, and
  • Professional Preston Scott taking the swings, not me.

I’m interested to see how this experiment turns out…

 

ADD Ball Exit Speed Swing Experiment

Equipment Used:

  • Zepp Baseball app (to measure Bat Speed, Hand Speed, Time to Impact, & Attack Angle),
  • Bushnell Radar Gun (to measure Ball Exit Speed, or BES),
  • Backspin batting tee,
  • Two yellow dimple baseballs (feedback markers),
  • Android GS6 video camera and Tripod, and
  • 34 inch wood bat.

Setup:

Preston Scott: Showing versus NOT Showing Numbers

Preston Scott: ‘NOT Showing’ versus ‘Showing Numbers’

  • Yellow dimple ball feedback markers to keep starting footwork the same = bat length
  • Tee was set one baseball’s length behind the front feedback marker, and tee height was about mid-thigh
  • Forward momentum was eliminated in this experiment, and Preston hit from a 1-2 second pause at landing
  • We stayed as consistent as we could with keeping the ball height and depth the same for most swings.
  • I used two yellow dimple ball markers to make my stance setup consistent…one was placed inside my back foot, close to the plate.  The other was placed one bat’s length ahead of the back marker.
  • The two tests in the swing experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘NOT Showing Numbers’ was letter ‘A’, and ‘Showing Numbers’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “warm up” factors.
  • On ‘NOT Showing Numbers’ swings, Preston kept his shoulders in line with the blue band on the ground in front of him (towards the pitcher).  And on ‘Showing Numbers’ swings, he kept his shoulders in line with the red band that was set at about a 30-degree angle from the blue band.
  • Preston Scott was sipping a protein shake throughout the length of the experiment to aid in recovery.
  • On both experiment days, Preston had finished “leg day” at the gym, so our warm-up was brief, followed by about 15-20 swings off the tee.
  • We had to break the 200 total swings (4 sets of 25 swing chunks each day) into two days, with the second day coming 1 week later because of time constraints.
  • It’s important to note, Preston and I were working on improving his mechanics slightly different both days (having nothing to do with ‘showing numbers’), but even though Day 1 (November 7, 2016), and a week later, Day 2 (November 14, 2016) swings may look a bit different, the slightly differing mechanics were used for BOTH ‘NOT Showing Numbers’ and ‘Showing Numbers’ tests, so as not to muddy the experiment results.

 

Data Collected (Zepp Baseball App):

‘NOT Showing Numbers’ Day 1 & 2 side by side comparison…

NOT Showing Numbers Day 1 & 2 (100 swings total)

‘NOT Showing Numbers’ Averages of averages: 71-mph Bat Speed at Impact, 27.5-mph Hand Speed Max, 0.165 Time To Impact, -25* Bat Vertical Angle at Impact, & 4.5* Attack Angle

‘Showing Numbers’ Day 1 & 2 side by side comparison…

Showing Numbers Day 1 & 2

‘Showing Numbers’ Averages of Averages: 76-mph Bat Speed at Impact, 28-mph Hand Speed Max, 0.162 Time to Impact, 28* Bat Vertical Angle at Impact, & 6* Attack Angle

Also, CLICK HERE to access the Google Drive spreadsheet with all Ball Exit Speed (BES) readings from the experiment.

 

Data Analysis & Conclusion

Starting with Zepp data analysis comparing the averages of averages:

  • 5-mph INCREASE in Bat Speed at Impact with ‘Showing Numbers’
  • 0.5-mph INCREASE in Hand Speed Max with ‘Showing Numbers’
  • .003 second DECREASE in Time to Impact with ‘Showing Numbers’
  • 3* INCREASE in Bat Vertical Angle at Impact with ‘Showing Numbers’
  • 1.5* INCREASE in Attack Angle with ‘Showing Numbers

Now, let’s see how the Ball Exit Speed averages compare between the two mechanics:

  • 76.02-mph BES when ‘NOT Showing Numbers’
  • 77.32-mph BES  when ‘Showing Numbers’
  • That’s a 1.3-mph average INCREASE when ‘Showing Numbers’
  • Translates between 5.2-feet to 7.8-feet of EXTRA batted ball distance – depending on if you calculate using 1-mph BES = 4-feet of distance OR 1-mph BES = 6-feet of distance.

 

Notes

  • In this experiment, if you look at the ‘NOT Showing Numbers’ swings, they were actually ‘Showing Numbers’.  In other words, Preston already shows his number to the pitcher well causing him a challenge to not show them.  Therefore on the ‘Showing Numbers’ swings, he showed them more.  I think that’s why we didn’t see as much of a difference in Ball Exit Speeds.
  • One of the big objections from some is that ‘Showing Numbers’ causes an increase in Time To Impact.  These results show it doesn’t – it actually decreases Time To Impact.  WHY is this? It has to do with ‘taking slack out of the system’ as it relates to compression/tension forces acting within the body.
  • Preston Scott generally does a great job of ‘Showing Numbers’, even before I started working with him, so he felt like he really had to try and keep from pulling the ball too much when ‘NOT Showing Numbers’. And as you can see in the video, he was still ‘Showing Numbers’ somewhat, even when he wasn’t suppose to!
