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.

 

Hypothesis

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:

  • Zepp Baseball app (to measure Bat Speed, Hand Speed, Time to Impact, & Attack Angle),
  • Backspin batting tee,
  • Two yellow dimple baseballs (feedback markers),
  • Flip camera to record swings, and
  • 33 inch bamboo bat.

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)?

How “Loading & Exploding The Hips” Can Be VERY Dangerous To The Lower Back…

 

 

We’ll get to the above video, but first let me be clear…

I’m not saying the pelvis doesn’t play a role in the swing, because it does.  However, I feel this spot reserved in the swing’s sequence of movements is hyper-focused on by a majority of hitting gurus.  More and more research is saying extreme “hip thrust” or “loading and exploding the hips” can be VERY damaging to the lower back over time.  You’ll see why in a moment, but for now please note that in this podcast episode, former USA Men’s Gymnastics Coach Sommers says the lower back portion of the spine isn’t made for a high degrees of rotation, but the T-Spine is.

Another thing I want to clear up, we don’t teach a 100% pure rotational mechanics here.  We teach a blend of linear-rotational.  Please CLICK HERE to read our thoughts on this.

In this post, we’ll cover:

  • How the spine stacks up (quick anatomy lesson),
  • Does consistent power come from the ground? And,
  • Teaching hitters a safer more effective swing.

Let’s get started…

How the Spine Stacks Up

Photo courtesy: MayfieldClinic.com

Here’s a quick anatomy lesson of the spine:

  • Cervical – the vertebrae in your neck, consists of 7 vertebrae, are allowed to flex, extend, and rotate,
  • Thoracic – the vertebrae in the middle of spine including shoulders, consists of 12 vertebrae, which are also allowed to flex, extend, and rotate, and
  • Lumbar – the vertebrae in lower back, consist of 5 vertebrae, and are allowed to flex and extend ONLY.
  • Sacral & Coccyx – there are 5 fused vertebrae here, and the Coccyx is sometimes referred to as the “tail” bone.

Did you catch that about the Lumbar?  It’s important, so it bares repeating…the vertebrae in the lower back IS NOT built to rotate!  Right now, you may be thinking: “Wait a minute, how’s that?!  I’ve seen millions of swings, and the hitter’s pelvis (and lower back) are rotating!!”

According to Charlie Weingroff, DPT, CSCS, a physical therapist, a trainer in New York City, and is pretty high up on the human performance food chain, says 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.”

Some movement experts (like Thomas Myers, author of the book Anatomy Trains), says the lower back can rotate no more than 7-degrees.  So according to the experts, 7 to 12-degrees is a good rotational range for the Lumbar section of the spine. That’s NOTHING compared to the 40-degrees of rotation – in each direction – of the middle and upper back section of the spine (which includes shoulders).

So what’s happening then?  You see, since the lower back vertebrae are not designed to rotate, it’s the surrounding muscles that are rotating a fixed object (non-rotating Lumbar), and is why you do see rotation.   The T-Spine vertebrae are built to rotate (again, this includes the shoulders), hence is why hitting coaches should put their rotational focus there and NOT the hips, pelvis, or low back.

Is rotating back hip through the zone necessary for power? Not in the way most coaches think.  Consider this quote from Physicist, Electrical Engineer, and author of the book The Spinal Engine, Dr. Serge Gracovetsky:

“The axial rotation of the spine cannot happen unless the spine is flexed by the right amount on the correct side. Coaching an athlete to throw without a proper spinal position is an invitation to severe torsional injuries.”

Dr. Gracovetsky is referring to this “flex” as a side bend with the shoulders.  The point is, USE THE SHOULDERS to accomplish rotational power.  Warning for coaches: if you shrug this information off because of ego or pride, and continue to teach pelvis, hip, or lower back dominant twisting swings, then you’re wearing holes in the low backs of your hitters.  Be careful because the link is there, and one can be held liable.

Don’t worry, I’ll show those coaches doing this unknowingly a safer way, at the end of this post…

Does Consistent Power Come from the Ground?

Water Polo Throw

Water Polo throw photo courtesy: YouTube Egy image from video

You may be thinking, but consistent power comes from the ground…the pelvis is the first to interact with Gravitational Forces, and that’s why you teach “hip thrust”. I agree with Ted Williams that the ‘Hips Lead the Way’, but they don’t contribute as much to consistent power as most think.  I know this may sound earth shattering for some, so please stay with me here.

CLICK the following link to a post I did titled, “The Swing DOES NOT Start From The Ground & Move Up?”

This brings me to the water polo throw video above…

Let me ask you a question, what do you think the “fastest throw in Water Polo” is?  Doing a Google search using those keywords brings up the following statement:

The overhand shot from a Croatian senior men’s national team player is recognized as the fastest shot in the world at 60 MPH (96.5 KPH). The overhand shot is the standard throwing motion in water polo. It is the same arm motion as a pitcher uses in baseball.”

So, let’s think about this.  In water, there are little to no Gravitational Forces, and the best human floating in water, can throw a volleyball-sized ball 60-mph?  What do you think the speed would be if this person was floating in water and threw a baseball-sized ball instead?  75-mph?  80-mph? 90-mph?  Okay, so let’s say this top-of-the-food-chain water polo player throws a baseball floating in water 80-mph.  You’re telling me a top-of-the-food-chain pitcher in the Big Leagues, throwing down a mound, can only throw 20-mph more (assuming 100-mph) than someone throwing the same ball floating in water?!

I dunno, but this begs the question, does the pelvis (and lower Lumbar), OR the shoulders (and T-Spine) contribute the most to pitching velocity AND Ball Exit Speeds?

If you need to see more examples about this, then CLICK HERE for a swing experiment titled, “How Much Ball Exit Speed Does Pelvis Contribute To A High Level Swing?” 

Consider this Tweet from one of my readers…

And I added the following comment…

So what role do I think the pelvis and low back play in the swing, if not power?  Directional force.  Allows the hitter’s swing to convert Centripetal into Centrifugal Force.  In a nutshell, the hitter’s “belt buckle” must point in the direction of the batted ball.

So what’s the answer?

Does Swing Start From The Ground & Move Up?

 

 

Start above video at about the 5:00-minute mark.  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 😉

Are hitting hip rotation lower half loading drills, using the legs, good for beginning baseball or softball swing power and quick hands?  My good friend Matt Nokes shines light on this hitting conundrum…

Matt Nokes: Why Rotating Back Hip Through Zone IS NOT Necessary For Power

 

 

In this Matt Nokes post, I wanted to bust a MYTH that Homer Bush brought up in his interview last week, and that is the MYTH that rotating the back hip through the zone is necessary for power.

This past week, I re-tweeted this from @HyattCraig (who is awesome btw), of one of two Miguel Cabrera homers in a game, and this particular one he hit to CF:

The next day after that Tweet, I found this private message from a follower on Twitter:

“Joey, Honest question. I love most everything you post and It goes with all of the philosophies I teach as an instructor, but this particular post I don’t quite understand. Are you saying a backwards step of sorts and having limited pelvic rotation are positives? I don’t feel like this is practical for anyone that isn’t 6’3 225 when the pitcher is providing the power at 93. If you have time could you please clarify this for me?”

My response:

“Thanks for asking about that. A couple things, we do have to be careful about taking from big slugger analysis. I don’t mind what the back foot does as long as its un-weighting AND not skipping forward too much. Miggy has a great line following the batted ball, it has to do with optimizing centrifugal (center-fleeing) forces. As an example, the belly button should point where the batted ball has exited. Coach Matt Nokes talks quite a bit about full rotation not being an absolute to hitting.”

Which brings me to the above video, where Coach Matt Nokes walks us through numerous examples of elite hitters not fully rotating their back foot (and pelvis) until after impact.  Also, let me define full rotation of the pelvis (or hips as some refer to it as), at least from what I see/hear/watch from other people out there…

Full pelvic rotation is getting the hitter’s belly button to face shortstop (for a righty, or 2B for lefty) on any pitch…inside, middle, and outside.  I’ve found this gospel preached from those who don’t ‘buy into’ or understand the loading of springy fascia in the torso, since to them, the shoulders would be seen as ‘inactive’, before the hitter starts turning.

Therefore the pelvis has to do all the heavy lifting.  This method is far from optimal, and NOT very safe for the lower backs of youth hitters across the nation, and even more disturbing will continue to keep Orthopedic surgeons in business.

CLICK HERE for a post I did explaining how the swing isn’t rotational OR linear, but that’s it’s actually linear, rotational, then linear again.  The purpose of this post, is to open up discussion about whether rotating the back hip through the zone is necessary for power IS or IS NOT a myth…

Lastly,

I wanted to share one of my favorite Coach Matt Nokes drills for practicing what he preaches.  It’s his “Around the Zone” soft toss (coaches please be careful with this):

We won’t spend a lot of time rehashing last week’s post, BUT I do want to bring up an important point that was talked about in the above Diamond Demo segment.  And it has to do with best hitters baseball barrel path…

Starting at about the 2-min, 15-second video mark, and continuing to the end, they talk about this idea of Khris Davis getting his barrel in the zone early, and keeping barrel in the zone late.  And this is where I’ve lied to you for the last 5-years!  I used to teach my hitters this same one-size-fits-all SUPER deep barrel path.  But what I found was this IS NOT true of the best hitters baseball bat paths…

 

 

WHY Hitters Baseball Current One-Size-Fits-All SUPER Deep Barrel Path Approaches are Losing

Let me tell you a story of how I stumbled onto this principle…

In January of 2018, I was working with one of my hitters, who has been working with me since he was 7 years old.  He’s 15 years old now, in the 8th grade, and consistently hits with a low to mid 80’s Ball Exit Speed off the Backspin Tee, using a wood bat.

His mechanics are pretty clean compared to my other hitters.  At the time, I was teaching my hitters the same one-size-fits-all SUPER deep barrel acceleration path, as many of you are now.  One day, we were working on hunting pitch zones, inner third pitches specifically, and he responded,

“Coach, I don’t feel like I can get to that inside pitch effectively.  Am I showing my numbers too much?”

This got me thinking, so I jumped on Twitter to look at the best hitters baseball bat paths.  Specifically, I was looking for hitters, like the ones on the split screen images above, crushing 94-mph+ on the inner third of the plate, and guess what I saw??

The ones who demonstrated the Catapult Loading System principles well (namely ‘showing numbers’), still did so at stride landing on inside heat! Did you catch that?!  ‘Showing numbers’ was irrelevant to crushing the inside pitch.  CLICK HERE for a post I did debunking that.  So what were they doing different on the inner third?

It had to do with what we call hitting a different “catcher’s glove”.  I won’t go into the details of that here because I already did at the following post titled: “Accelerate Barrel Rearward Like Mike Trout”.  The best hitters baseball barrel path isn’t about a one-size-fits-all approach to all pitches and timing.

Here’s the DANGER for hitters using a one-size-fits-all SUPER deep barrel acceleration approach…

Signs that pitcher’s are smartening up to countering this seemingly effective low in the zone barrel approach?  Pitchers are now using this, which Perry Husband calls Effective Velocity (EV), to exploit hitters with longer barrel paths.

In short, 2018 homers are down, in addition to having a few months in the season where overall offensive strikeouts outweigh hits in the Big Leagues.  This is troubling.  To give a clue, check out Perry’s video explaining why Chris Davis (Orioles) is having issues with this one-size-fits-all barrel path…

 

If hitting coaches don’t smarten up to this soon, then they’ll be rendered obsolete, irrelevant to the hitting community, and ultimately out of a job.  That’s not an exaggeration, and is where the puck is going, believe me.  Now, let’s look at the behavior of different “catcher’s glove” approaches on inner, middle, and outer third of the plate pitches…

How Much Ball Exit Speed Does Lower Body Contribute To A High Level Swing?

 

In this baseball and softball video post, we’ll be looking at whether preloading upper body hitting torque or using lower half hip rotation contributes for more power.  Check out this swing drills over rotating experiment…

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) did a small thought provoking swing experiment that looked at how much value the lower half contributes to the swing.  Most popular hitting instructors treat the lower half like a JoBu shrine in the movie Major League.  Don’t get me wrong, the lower half has a role, but I disagree on the importance most put on it.

Using the Scientific Method…

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 lower half 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 lower half in the swing, compared to the “lower half 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 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 lower half contributes about one-third to the Exit Speeds of these four hitters.
