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)?

Question: Do More Expensive Bats Increase Bat & Ball Exit Speeds?

 

 

In this baseball batting practice Mizuno bat model experiment using the Zepp (Labs) Baseball app & Bushnell radar gun, I wanted to use the Scientific Method to analyze what would happen to Bat and Ball Exit Speeds comparing the performance of two different Mizuno bat models, but the same 34-inch, 31-ounce size:

 

Background Research

MIZUNO MAXCOR ($150-400)

According to the Mizuno website, the focus of this bat is maximizing Ball Exit Speed and backspin.  Some key features are (Mizuno site):

  • Viscoelastic Sleeve: Creates a wider circumferential sweet area.
  • New Variable Wall Thickness Alloy Core: Increases the sweet area across the length of the barrel, using aircraft aluminum alloy used to keep overall weight low.
  • Dynamic Damper: Transition piece from barrel to handle absorbs vibration for better feel.
  • New Improved Synthetic Leather Grip: Provides tack and great feel.
  • Lower more balanced swing weight for increased swing speed.
  • BBCOR certified, approved for NCAA & NFHS play
  • Barrel Diameter: 2 5/8″

MIZUNO GENERATION

According to Mizuno’s site, the Mizuno Generation baseball bat was designed with two things in mind:

  1. A bigger sweet spot, and
  2. Balance – (lighter swing weight, which can result in faster bat speeds).

Key features of the baseball batting practice Mizuno Generation bat (Mizuno site):

  • Patented wall thickness technology varies the wall thickness across the barrel, creating a massive sweet area for ultimate forgiveness
  • Single wall aerospace grade aluminum alloy used for maximum combination of performance and durability
  • Balanced swing weight for increased swing speed and bat control
  • Digi-Grip for great feel and durability
  • BBCOR certified, approved for USSSA
  • Barrel Diameter: 2 5/8″

Another factor in this baseball batting practice Mizuno bat model experiment will be breaking in a non-wood bat.  CLICK HERE for a good YouTube video on how to break-in a composite bat.  Now, both Mizuno bats are not composites, but I’m sure the breaking in process with any alloy, will have an affect on Ball Exit Speeds.

We’ll adjust the data to address breaking in the bat in the Notes section.

 

Hypothesis

Based on the above baseball batting practice Background Research from Mizuno (albeit promotional materials), and the fact the MaxCor is double the price, I’d expect a much better performance in Bat and Ball Exit Speeds using the MaxCor model bat versus the Generation.

 

Baseball Batting Practice: Mizuno Bat Model Experiment

Equipment Used:

Setup:

  • All baseball batting practice swings were taken off the tee.
  • 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 plus two baseballs in front of the back marker.
  • CLICK HERE for the Google Drive excel document with all the Ball Exit Speed (BES) readings.
  • We deleted radar gun mis-reads that registered below 30-mph on the gun.
  • Therefore, we deleted 11 mis-reads from the Mizuno MaxCor bat data, and averaged all MaxCor BES readings to 89 swings.
  • Also, we deleted 7 mis-reads from the Mizuno Generation bat data, and averaged all Generation BES readings to 93 swings.
  • The two tests in the experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  Swinging the “Mizuno MaxCor” were letter ‘A’, and
    “Mizuno Generation” were letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “not being warmed” up factors.

Data Collected (Zepp Baseball App):

Baseball Batting Practice: Mizuno Bat Model Experiment

According to the Zepp app, the Mizuno MaxCor came out supreme in all areas except the Attack Angle…

 

Data Analysis & Conclusion

ZEPP READINGS:

  • Avg. Bat Speed at Impact increased by 3-mph using the Mizuno MaxCor,
  • Avg. Max Hand Speed increased by 2-mph using the Mizuno MaxCor,
  • Avg. Time to Impact decreased by 0.063,
  • Avg. Bat Vertical Angle at Impact decreased by 1-degree using the Mizuno MaxCor, and
  • Avg. Attack Angle decreased by 4-degrees using the Mizuno MaxCor.

BUSHNELL BALL EXIT SPEED READINGS (CLICK HERE for Google Excel Doc):

  • Avg. Ball Exit Speed increased by 4.6-mph using the Mizuno Generation bat,
  • Top out Ball Exit Speed was 95-mph using the Mizuno Generation bat, and
  • Top out Ball Exit Speed was 90-mph using the Mizuno MaxCor bat.

 

Notes

  • Now, we can’t compare apples to apples baseball batting practice data using the Zepp app and Bushnell radar gun.  If I had one more Bushnell radar gun capturing my bat speed readings perpendicular to my chest, then that would’ve been an interesting comparison.
  • I felt much more balance with the Mizuno Generation.  I also felt like I was more consistently hitting the sweet spot, as their marketing suggests.  For some reason it was tough feeling a consistent sweet spot using the MaxCor, maybe because of the “Dynamic Damper: Transition piece from barrel to handle absorbs vibration for better feel”.
  • It takes about 100-200 swings to break in a non-wood bat, at least according to the following YouTube video on How-To Break-in a Composite Bat.  I’m going to share a Zepp app screenshot comparing the first 100 swings using the Mizuno MaxCor (from this experiment), to the first 100 swings using the Mizuno Generation (from the Baseball Swing Tips: Mizuno Bat Size Experiment):
Baseball Batting Practice: Mizuno Bat Model Experiment

Look at the near identical performance Zepp data between the two bats when we compare their first 100 swings…

  • How about comparing the Ball Exit Speeds of the first 100 swings…according to this Google spreadsheet, the Mizuno MaxCor Avg. Ball Exit Speed was: 83.5-mph.  And according to this Google spreadsheet from a couple weeks before, Avg. Ball Exit Speed using the Mizuno Generation 34/31 was:  88.3-mph.

The Bottom Line?

Well, according to the baseball batting practice Mizuno bat model experiment data, it looks like the Generation model holds the performance edge when it comes to Ball Exit Speed, almost a 5-mph difference.  That’s about 20-feet of extra distance!  From how the experiment turned out, I’d save the $200 and buy a Mizuno Generation.  Now, this data doesn’t mean EVERY expensive bat will under-perform it’s more economic brethren, it just means you need to tinker and test to find the truth.

Pro XR Dovetail Handle Wood Training Baseball Bat Swing Review: Is It BETTER Than an Axe & Puck?

Learn safety benefits of the Pro XR dovetail handle wood training baseball bats and whether there is improved performance in this swing experiment review. Are Pro XR handled wood bats better than the Axe or Puck handled knob bats?

Does a Modified Bat Handle Increase Bat & Ball Exit Speeds?

 

 

Baseball Hitting Drills for Contact: ProXR Bat Experiment

ProXR bat knobs are similar to an axe handle, but are more rounded…

In this baseball hitting drills for contact bat knob experiment using the Zepp (Labs) Baseball app & Bushnell radar gun, I wanted to use the Scientific Method to analyze what would happen to Bat and Ball Exit Speeds when using the same model and sized wood bat, but the only difference being that one bat has a regular knob, and the other a ProXR knob.

 

Background Research

Baseball Hitting Drills for Contact: ProXR PSI comparison

A Washington University study found there was a 20% to 25% reduction in compression forces in the hands when using a ProXR technology.

My fascination with this all started when Grady Phelan, the Founder and President at ProXR, LLC, wrote this LinkedIn post titled, Baseball’s Broken Hamate Plague.

After I reached out, Grady was open to the idea of doing a Zepp and Ball Exit Speed baseball hitting drills for contact experiment.

Grady shared the following research about his ProXR technology over email…

“One of the experiments we did early on with ProXR, as part of our due diligence before we went to market, was to measure the compression forces in the hands during a swing. I was fortunate enough to be able to work with some researchers at Washington University School of Medicine, Bio-Mechanics lab here in St. Louis. We connected a conventional bat and a ProXR bat to digital pressure sensors and had a batter take some swings. We were able to dial into the area of the hypothenar (the heal of your hand below your pinky) and compare the difference in compression.

What we found was a 20% to 25% reduction in compression forces when using a ProXR technology. The peak compression happens immediately AFTER intended contact when the hands roll over the central axis of the bat and the knob.  The smaller peaks in between the high compression peaks are from the batter getting the bat back into the load position and we took out the time in between swings to condense the chart.”

Around the same time, I saw this USA Today article titled, Dustin Pedroia is on a hot streak with an odd-looking bat designed to help hitters.  I asked Grady if this was his bat, and he replied:

“Pedroia is actually using something called an axe that is being put on a Victus bat. There is some minor confusion in the market given the axe’s similar look with ProXR.

Here’s the top-line difference between ProXR and the Baden product: if you’ve ever swung an actual axe (chopping wood), which the Baden product is based on, you know that the swing path is linear, meaning it drives the hands to the point of contact AND (this is probably the most important point) the swing ends at contact. This is critical. The oval shape of an axe handle and the general configuration of the axe handle evolved over thousands of years specifically to drive the axe head to the point of contact (this also applies to swords, hammers and other linear-path swing implements). The oval shape locks the hands into alignment with the swing path and PREVENTS the hands from deviating from that swing path. In sharp contrast, you know a baseball swing is rotational – meaning the bat must fully rotate around the batters body and the hands MUST roll over the central axis of the bat to compete the swing. This gives hitter the ability to both, make adjustments during the swing and complete the rotational swing path. Putting an oval axe handle on a baseball bat is counter-intuitive to the requirements of a rotational baseball swing. Imagine trying to adjust your swing on a breaking ball or change-up when the shape of the handle is resisting those adjustments.
In contrast, ProXR was designed from the ground-up specifically for a rotational baseball bat swing. It reduces compression in the hands and gives batters improved performance. Additionally, we tested our designs before we went to market and continue to do ongoing research and testing. As a side note, ProXR was accepted into the National Baseball Hall of Fame in 2011 because it is the first angled knob bat ever used in regular season games.”

Hypothesis

Based on the ProXR technology research, I was convinced the bat would alleviate compression forces in the hands, particularly the hitter’s bottom hand.  However, my biggest question was, are we sacrificing performance to be safer?  I think the ProXR technology, although safer, will sacrifice some performance.

The reason I labeled this a “baseball hitting drills for contact” experiment will become clear in the “Notes” section of the post, so stay tuned…

 

Baseball Hitting Drills for Contact: ProXR Bat Knob Experiment

Equipment Used:

  • Zepp Baseball app,
  • Bushnell radar gun,
  • ATEC Single Tuffy Tee,
  • Flip Camera,
  • 33-inch wood bat model 243A with regular knob, and
  • 33-inch wood bat model 243A with ProXR knob

Setup:

  • All swings for the baseball hitting drills for contact experiment were taken off the tee.
  • 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 plus two baseballs in front of the back marker.
  • CLICK HERE for the Google Drive excel document with all the Ball Exit Speed (BES) readings and calculations.
  • We deleted radar gun mis-reads that registered below 30-mph on the gun.
  • Therefore, we deleted 3 mis-reads from the ProXR bat knob data, and averaged all ProXR BES readings to 97 swings.
  • Also, we deleted 2 mis-reads from the regular bat knob data, and averaged all regular bat knob BES readings to 98 swings.
  • The two tests in the baseball hitting drills for contact experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  Swinging the “ProXR Knob” were letter ‘A’, and
    “Regular Knob” were letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “not being warmed” up factors.

Data Collected (Zepp Baseball App):

Baseball Hitting Drills for Contact: ProXR Bat Knob Experiment

A slight baseball hitting drills for contact advantage goes to the ProXR Knob…

 

Data Analysis & Conclusion

ZEPP READINGS:

  • Avg. Bat Speed at Impact increased by 1-mph using the ProXR knob bat,
  • Avg. Max Hand Speed didn’t change,
  • Avg. Time to Impact decreased by 0.004 swinging the ProXR knob bat,
  • Avg. Bat Vertical Angle at Impact decreased by 2 degrees using the ProXR knob bat, and
  • Avg. Attack Angle decreased by 4 degrees using the ProXR knob bat.

BUSHNELL BALL EXIT SPEED READINGS (CLICK HERE for Google Excel Doc):

  • Avg. Ball Exit Speed decreased by 0.4-mph using the ProXR bat knob, and
  • Top out Ball Exit Speed was 93-mph using both the ProXR and conventional bat knob.

Notes

  1. In ProXR founder Grady Phelan’s initial testings of professional players, some of the players recorded a 3 to 10-mph bat speed increase using his ProXR knob.  Now, I have a theory as to why my numbers were much smaller…
  2. For all 208 swings I was playing with two baseball hitting drills for contact mechanical elements in my swing: 1) squeezing the bottom three fingers of my top hand only, from the moment I started my swing (picked up my front foot), through impact.  And 2) having more of a “hunched over” posture at the start of the swing.  I did this for all swings, so as not to “muddy up” the experiment.
  3. The finger pressure may have neutralized the affect of the ProXR knob, since most of the “shock” at impact was taken by my top hand.  Whereas a normal hitter not using top hand finger pressure would absorb the shock in the hamate bone, in their bottom hand, using the regular knob bat.
  4. Playing around with both baseball hitting drills for contact elements of #2 above, I compared the Ball Exit Speed numbers from my previous experiment looking at the difference between the Mizuno Generation ($200 bat) to the Mizuno MaxCor ($400) bat where I wasn’t using the two mechanical changes.  Interestingly, my average Ball Exit Speed with the $400 alloy MaxCore was 83.5-mph and top out exit speed was 90-mph.  With the wood bats, my average Ball Exit Speed was 89 to 90-mph, and my top out exit speed was 93-mph.  That’s a 6.5-mph jump in average & 3-mph boost in top out exit speed using a wood bat over a non-wood!!  That’s 26 more feet on average, and 12 more feet in top out distance added using finger pressure and the “hunch”!
  5. By using the two principles in #2 above, I was able to hit the “high-note” more consistently.  I also had less “mis-reads” in this experiment, using the radar gun (5 total out of 208 swings), versus the Mizuno bat model experiment (18 total out of 200 swings).  This is why I labeled this experiment “baseball hitting drills for contact”.
  6. After about 50 swings in the the ProXR bat knob baseball hitting drills for contact experiment, I could tell you what my Ball Exit Speed readings were going to be after each cut, +/-1 mile per hour.  Crazy!

The Bottom Line?

Well, according to the baseball hitting drills for contact ProXR bat knob experiment data, it looks like the ProXR knob holds a slight edge in performance versus the convention knob. Coupled with the fact that the ProXR knob reduces compression forces on the hands by 20 to 25% has me convinced that ProXR bat knob technology is a can’t lose tool for a hitter’s toolbox.

Alex Gordon Swing Analysis Experiment: Top Out Bat Speed By Striding Closed?

 

Question: Does Striding Front Leg Closed Increase OR Decrease Bat Speed?

I was taught my whole playing career to stride front foot closed.  Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze whether striding with the front leg closed will have a positive or negative effect on bat speed.

Background Research

Here are a couple posts to further your understanding of spinal engine mechanics, as we move to discover what effect striding with a closed front leg will ultimately have on bat speed…

Also, CLICK HERE to watch this video from ZenoLink’s Chris Welch on stride principles.

Hypothesis

Based primarily on my research and study of Dr. Serge Gracovetsky’s book The Spinal Engine, I believe landing with an open front leg – like Alex Gordon – will result in increased bat speed and farther batted ball distance.  Landing closed with the front leg – like Kansas City Royals catcher Salvador Perez (who popped out to end the 2014 World Series) – will result in an inefficiency to hitting inside and high pitches.  And will allow other compensations to occur such as rolling over, pulling the head, and the front shoulder flying open.

Alex Gordon: Striding Open/Closed Experiment

Equipment Used:

  • Zepp Baseball app,
  • ATEC Tuffy Batting Tee,
  • Bownet,
  • Rawlings Official NCAA Baseballs,
  • Two yellow dimple baseballs (feedback markers),
  • Flip Video Camera and Tripod, and
  • 33 inch, 30 ounce Pinnacle Bamboo bat.

Setup:

  • Yellow dimple ball feedback markers = my bat length, plus two baseballs
  • Distance from plate = end of the bat touching inside corner of plate, and knob of bat touching my mid-thigh
  • 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 I hit from a 1-2 second pause at landing
  • First 100 baseballs hit I was striding with a CLOSED front leg
  • Last 100 baseballs hit I was striding with an OPEN front leg
  • There was about 15-30 minute break between both Alex Gordon & Salvador Perez Experiments

Data Collected (Zepp Baseball App):

Alex Gordon: Top Out Bat Speed By Striding Open?

First 100 balls (striding CLOSED), last 100 balls (striding OPEN)

Data Analysis & Conclusion

Observations from the Zepp Baseball app screen capture above:

  • Striding OPEN added 1-mph of bat speed on average
  • Interestingly, striding CLOSED added 0.024 “Time To Impact” on average

Not much change there…but the devil’s in the details…

Alex Gordon Closed/Open Stride Experiment

Breakdown of Alex Gordon Striding Closed Experiment (swings & bat speed)

  • Striding CLOSED shifted bat speed downstream into the [< 69] to [70-74-mph] ranges
  • Striding OPEN shifted bat speed upstream into the [75-79] to [80+ mph] ranges
  • Striding CLOSED top out bat speed was 81-mph…80-mph (once) and 81-mph (twice)
  • Striding OPEN top out bat speed was 83-mph…80-mph (6-times), 81-mph (3-times), 82-mph (3-times), & 83-mph (once)

 

Notes

Alex Gordon: Top Out Bat Speed By Striding Closed?

Salvador Perez never had a chance striding closed against Madison Bumgarner photo courtesy: MLB.com

  • Striding open with the front leg definitely increased top out bat speed (83-mph v. 81-mph).
  • There was a better chance to maintain higher bat speeds with striding open.
  • During the Alex Gordon Experiment, when striding front leg open, my front foot was at a 45-70 degree angle.
  • I also felt that I had an easier time accelerating the barrel down (towards catcher’s glove) when my stride leg was open, which helped keep my bat speed more consistent.  I felt like I had to pull across my body (or chop down) striding with a closed front leg, which made my bat speed more erratic during the first part of the Experiment.
  • I purposely eliminated forward momentum from the Experiment because I wanted to isolate how much striding closed took away from bat speed.  In addition, I wanted to preserve accuracy in execution with the two different mechanical scenarios.

 

The Bottom Line?

Spinal engine mechanics drive all human movement, according to Dr. Serge Gracovetsky.  When we do things to hinder efficient spinal engine mechanics, reciprocal inhibition takes over depressing a hitter’s ability to maintain higher bat speeds over longer periods.  In addition, striding with a closed front leg will cause a hitter to be inefficient getting to inside and higher pitches.  A great number of coaches teach hitters to stride with the “front foot closed”.  This is the very reason the following compensations occur that these coaches waste their time trying to correct!!

  • Front shoulder flying open,
  • Head pulling out, and
  • A shorter hand and barrel path to the ball, resulting in the
  • Barrel having limited time on the plane of the pitch, which increases mis-hits and strikeouts.

This is why I think Salvador Perez had a hard time handling Madison Bumgarner.  MadBum kept busting him up and in.  Because Salvador Perez strides closed I believe this stunted his chances of knocking in Alex Gordon from third at the end of the game.

  6. [YOU ARE HERE] Overload Bat Training: Hitter Has To Work Butt Off To Resist “Casting”

Here’s what we discuss in this episode:

  • WHY a hanging FB (located down/away) is more likely to get hit harder than hanging off speed or breaker,
  • How every Major League hitter locks lead arm, may not talk about it, may not practice it, but when they hit their hardest “bolt” – they’re doing it,
  • Overload training: WHY Heavier weight is better, especially end loaded, hitter has to work their butt off with end loaded to keep from “casting”,
  • How changing length of bat and weight helps hitter learn how to adjust timing – training body to be more sensitive to timing,
  • And much more!

Without further adieu, here’s Hitting Jam Session #6…

Show Notes

  • At about the 2-minute mark, Perry and I discuss putting together a subscription based coaching program for coaches which would have access to our courses and have weekly coaching calls to mentor coaches, Twitter bantar…pitching philosophy used to be 70% fastballs, mixed up/down & inside/outside, then moved to away/away and down/down because hitting was hard to lift far away, then hitters started lifting those pitches – Moneyball & analytics, hitters focus now on swinging up and everyone on the field can go oppo bomb, teams will start elevating fastballs which will set in motion more stuff, odds of “up swings” getting to high heat will be more challenging, is the idea of throwing fastballs down “stupid”?  Perry did micro study…MLB – RHP v. RHH: FB up/in = 84.6-mph BES, SL down/away = 82.2-mph BES, CB down/away = 80.1-mph BES, & CH down/in = 86.5-mph BES (chose pitches that would be in that FB tunnel), a hanging FB (located down/away) is more likely to get hit harder than any other hanging off speed or breaker because every hitter is focused on the FB.
  • At about 12-minute mark, Perry study comparing middle three, upper three, and above three part of the zone with off speed and breaking (hanging stuff) versus the bottom three parts of the zone with fastballs…he counted number of hitters that averaged 90-mph BES…12 to 1 hitters favoring fastball down versus changeup up (12X more likely to avg. 90-mph BES), not a fair study, just a ballpark, today more likely to hit a fastball down than a hanging changeup up,
  • At about 14-minute mark, locked lead arm follow up, reader saying not many hitters using locked lead arm…Williams and Choo both lock lead arm and pull the ball – can locked lead arm help going to opposite field, every Major League hitter locks lead arm, may not talk about it, may not practice it, but when they hit their hardest bolt – they’re doing it, Perry talks about one of elite Fastpitch Softball hitters in the country Todd Budke locked lead arm (YouTube video of him hitting oppo dinger) – facing guys that made Randy Johnson look like a thumber 80-86-mph velo from 46-feet, bent front arm results in more balls fouled back, evidence of what happens when guys hit up/in pitch – they’re doing it with bent lead arm, can we do better than that with locked lead arm?  What happens when all fastballs go away EXCEPT the up/in fastball?  The “adjustable” hitting mindset isn’t going to work anymore when pitchers get more EV efficient
  • At about 23-minute mark, do young hitters from High School on down learn how to “hunt” pitches or wait till pitchers get better? Thank God pitchers still make mistakes, but what pitchers are being taught right now is to stay down with fastballs, sliders, etc.  It’s predictable.  When pitchers TRY to be EV efficient, things will be troublesome for hitters, the basic hitting approach of today is like a 2-strike approach (the “adjustable” swing), the adjustment will be much harder for hitters when EV tunnels are enforced, will happen at Big League level first, Greinke example using certain pitches to take hitter’s attention away from where hitter’s strength is, creating shiny objects, get swing down right, then figure out how to apply it,
  • At about 33-minute mark, I ask Perry his advice on how to teach 6-8yo to get more on time, Inner Game of Tennis book drills – 100% on-time 100% effective with swing mechanics (not about swinging as hard as you can), take and control “A” swing – best swing, being on-time to that pitch,

No.  Is it effective? Yes, but it doesn’t go far enough, would you get stronger with light weight in gym?  Heavier weight is better, especially end loaded, hitter has to work their butt off with end loaded +10 and control line drives, hitters will “cast” with an end loaded bat – but hitter MUST keep that from happening, Perry over/under load study +10 and -10 results were astounding looking at video of players and data – consistency numbers went up and recruitment of lower half, fastpitch softball Frosh case study 6-weeks no change in mechanics went from 55-mph to 62 or 63-mph BES, Reactive Neuromuscular Training (RNT) – this is what overload training is doing, feeding the “mistake”, Cook bands, TheStartingLineupStore.com Anchor Bat +4 to +6 and -5 wood bats over/under load system, locked lead arm, end loaded bat, and releasing barrel into “belly button” catcher’s glove,

Buster Posey Swing Breakdown Experiment: ADD 6-mph To Bat Speed Not ALL In The Hips?

 

 

Buster Posey VIDEO: Not ALL In The Hips [Experiment]

Question: Is Increased Bat Speed ALL in the Hips?

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze whether Buster Posey’s hips OR spinal mechanics is what increases bat speed.

Background Research

Most elite hitting instructors, pros, and Hall of Famers think it’s ALL in the hips.  The “it” is a mystery even to them.  It shouldn’t be this way.  When we look at proven human movement science, we find that just firing the hips isn’t good enough.  My question to those people is, what about the piece of hardware above the pelvis, attaching it to the shoulders – the spine?

Before getting into the experiment and analyzing Buster Posey’s swing, we need to lay ground work first.  Watch this THREE videos first:

  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

Based primarily on my research and study of Dr. Serge Gracovetsky’s book The Spinal Engine, and Thomas Myers’s book Anatomy Trains, I believe a hitter like Buster Posey, that shows the pitcher their numbers – while keeping the hips in neutral – creates the separation (or spinal torque) needed before landing to produce natural friction-free repeatable power.

Rather than just focusing on the hips to go first, and the front shoulder to stay on the pitcher.  In the experiment, for the sake of brevity, I’ll differentiate between the two with “showing numbers” or “NOT showing numbers”.

Buster Posey: Not ALL in the Hips Experiment

Equipment Used:

  • Zepp Baseball app,
  • ATEC Tuffy Batting Tee,
  • Rawlings Official NCAA Baseballs,
  • Two yellow dimple baseballs (feedback markers),
  • Flip Video Camera and Tripod, and
  • 33 inch, 30 ounce Pinnacle Bamboo bat.

Setup:

  • Yellow dimple ball feedback markers = my bat length, plus two baseballs
  • Distance from plate = end of the bat touching inside corner of plate, and knob of bat touching my mid-thigh
  • 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 I hit from a 1-2 second pause at landing
  • First 100 baseballs hit was “NOT showing numbers”, focusing on hips first, and front shoulder pointing at the pitcher at landing
  • Second 100 baseballs hit was “showing numbers”, focusing on showing numbers, slight down shoulder angle, and hiding the hands
  • There was about 30-45 minute break between both Buster Posey Experiments

Data Collected (Zepp Baseball App):

Buster Posey Experiment: Zepp Baseball App comparison

Difference after 100 swings…

 

Data Analysis & Conclusion

  • Average bat speed for NOT showing numbers at landing: 73-mph
  • Average 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
  • Hand speed max for showing numbers was: 29-mph (+2-mph)

As you can clearly see, “NOT showing numbers” puts a hitter at a clear repeatable power DISADVANTAGE.

 

Notes

Andrew McCutchen showing his numbers like Buster Posey

  • I don’t go out and take 200 swings in a given day, so I was getting fatigued by the time I got to the last hundred swings (“showing numbers”) part of the experiment.  Goes to show this isn’t about muscles, but connective tissue.
  • Remember, I purposely eliminated forward momentum from the Buster Posey Experiment because I wanted to reveal how “showing the numbers” can effect a hitter’s bat speed.  CLICK HERE to see the results of a Forward Momentum Experiment I did using the Zepp Baseball App.
  • “Showing the numbers” IS NOT adding more rotational ground to make up during the Final Turn.  It’s a natural way of super-charging connective tissue over muscles.
  • A slight bend at the waist (hip hinge) towards the plate – before landing – improves efficiency, not detracts from it.  Just look at Posey, McCutchen, and Pujols pictured hitting home-runs in this post.  This is how an athlete takes the slack out of the posterior chain (calves, hamstrings, butt, and back).  ALL shapes and sizes use it.
  • During NOT showing the numbers, I felt like I had to guide my hands more.  It took more effort to extend through the ball instead of rotating off (rolling over), than with showing the numbers.
  • Make sure when “showing the numbers”, the hitter isn’t losing sight of the incoming pitch with the back eye.
  • Also, make sure when using a slight down shoulder angle that the head stays in-line with the spine.  The angle is slight, about five to ten-degrees.

 

The Bottom Line?

When we analyze hitters like Buster Posey, we NEED to hold our analysis to a higher standard.  Proven human movement science.  We have to go away from mechanical fixes based on “feelings”.  The “Oh, I’ve been working on this and it seems to work”, isn’t good enough.  Neither is, “Ted Williams said so!”  Or, “I watch 25-hours of high level hitting footage in a day, so listen to me.”  That stuff DOES NOT matter.  Science does.  I want to see the data, NOT listen to feelings.  The heavy lifting has been done for us.  It’s up to us to apply it.

Why I Teach Hitters To ‘Show Numbers’ (And Maybe You Should Too)

 

 

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.

  • Zepp Baseball app (to measure Bat Speed, Hand Speed, Time to Impact, & Attack Angle),
  • SwingAway Bryce Harper model hitting station,
  • GS6 android phone to record swings, and
  • 33 inch bamboo bat.

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.

Baseball Batting Cage Drills: Here’s A Quick Way To Hit Less Ground-balls

 

 

Question: Does The BackSpin Batting Tee Help Hitters Elevate The Ball?

In this baseball batting cage drills experiment using the Backspin batting tee, I wanted to use the Scientific Method to analyze what would happen to a hitter’s spray chart (ME!!) by taking:

  • 100 swings using a conventional tee (ATEC Single Tuffy Tee), versus
  • Taking another 100 swing using Taylor and Jarrett Gardner’s BackSpin batting tee.

I’ve done a couple posts promoting what Taylor and Jarrett are doing with the Backspin Tee because I really believe in their product and what it can do for young hitters in getting the batted ball off the ground.  Whether we’re talking baseball, fast pitch softball, and slow pitch softball…

And to let you know, this experiment has been brewing in my head since the summer of 2015, but the stars just didn’t align…until NOW!

Background Research

Here are two baseball batting cage drills posts mentioned earlier, to give some background on the research for The Backspin batting tee:

Hypothesis

Baseball Batting Cage Drills: ATEC Tuffy Single Batting Tee

Okay, so I cheated a little bit…

Before the OFFICIAL baseball batting cage drills swing experiment, I’ve been using the Backspin batting tee with my local hitters and the results have been positive.

And now, I’m making my Hypothesis official…

I think by using the Backspin batting tee, it will allow the hitter to cut down on ground-balls, and will empower them to get more effective at putting the ball in the air (line drives primarily).

In addition, I think that not only will the tee reduce a hitter’s ground-balls, but will contribute to above average line drive launch angles.  Average line drives would be within the reach of a fielder.

 

Baseball Batting Cage Drills: Backspin Batting Tee Experiment

Equipment Used:

  • Backspin Batting Tee,
  • ATEC Single Tuffy Tee,
  • Flip Camera,
  • Baseballs, and
  •  33-inch ProXR wood bat

Setup:

  • I had two of the same laminated images of the batting cage I was hitting in (Hitting Spray Chart images below).
  • After each swing, I’d use a Sharpy pen to mark where the batted ball hit first (on the ground or the location on the batting cage netting), right after coming off the bat.
  • All swings for the baseball batting cage drills experiment were taken off either a Backspin or ATEC Tuffy Single tee.
  • I used the Backspin batting tee rubber cone for baseballs (they have one for softballs as well).
  • I stayed as consistent as I could with keeping the ball height and depth the same for both tees.
  • 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 plus two baseballs in front of the back marker.
  • The two tests in the baseball batting cage drills experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  Hitting off the “Backspin Tee” was letter ‘A’, and off the “Conventional Tee” was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “not being sufficiently warmed up” factors.

Data Collected (Hitting Spray Charts)

Backspin Batting Tee Spray Chart:

Baseball Batting Cage Drills: BackSpin Tee Spray Chart

The Backspin tee spray chart is cleaner and resembles a bit of a tornado

Conventional Tee Spray Chart:

Baseball Batting Cage Drills: Conventional (Regular) Tee

As you can see, the spray chart is a bit messy…

 

Data Analysis & Conclusion

  •  The Backspin batting tee spray chart looks much more tidy than the “regular” tee chart (the former looks like a tornado),
  • You can see when using the conventional tee, I tended to pull the ball to left side of the cage.
  • There are definitely a higher concentration of batted balls in the above average line drive spots (not within reach of the fielders), using the Backspin batting tee, and
  • There were more balls hitting the ground or bottom of the cage when using a conventional tee.

 

Notes

  1. Addressing the excessive of pulled balls using the conventional tee, I thought maybe my tee was moving on me (getting too far out front).  I even tried pushing the regular tee slightly deeper than the position I started it in for a couple swings, to counter this, but that wasn’t the issue.
  2. Now, here’s where it gets interesting…remember in the “Setup” section above, I hit on the Backspin Tee (‘A’) FIRST.  I started to notice a pattern after switching tees…I didn’t have an issue getting the ball in the air with the Backspin tee, sometimes getting into the pop-fly territory.  But what I found was after taking a Backspin tee 25-swing chunk, the first 10-15 swing launch angles off the conventional tee mimicked what I was getting with the Backspin Tee.  As the conventional tee round approached the last 10-15 swings, the launch angle slowly creeped downwards into the average line drive arena.  So when I repeated TWO conventional tee 25-swing chunks (the BB in the ABBA pattern), by the time I got to the end I was having a hard time getting the ball back up again using the conventional tee.  And on the last BAAB 25-swing chunk pattern (last 100 swings), I noticed the same thing emerge.
  3. It was like the “magic” of the Backspin tee wore off after 10 swings into hitting on the conventional tee. My Hypothesis?  If I took 100 STRAIGHT swings on a conventional tee, then 100 STRAIGHT on a Backspin tee, I’m willing to bet there would be WAY more ground-balls and average line drives using the conventional tee than I got in this baseball batting cage drills experiment.
  4. The other weird thing (in a good way) I noticed hitting off the Backspin batting tee, was that it trimmed up my spray chart (making it look more like a tornado rather than a cinder block).  I rarely pulled the ball towards the left side of the cage hitting off the Backspin tee.  And the ones I did pull that way, I’d be willing to bet it was after hitting off the conventional tee. CRAZY!

The Bottom Line?

Well, the baseball batting cage drills experiment data showed that not only did the Backspin tee elevate ball launch angles, but it also cleaned up horizontal outcomes.  Meaning, I didn’t hit the ball to the left side of the cage as frequently when using the Backspin tee than I did with the conventional tee when the ball is located virtually in the same position every swing.  Also, the “Backspin tee effect” lasted a good 10-15 swings into switching over and using the conventional tee!

Hitting May Be Dangerous To Your Spine [Swing Experiment]

 

 

Question: Does Having a ‘Hollowed Posture’ Boost Bat Speed Over NOT?

In this baseball hitting drills off tee experiment using the Backspin batting tee, I wanted to use the Scientific Method to analyze the benefits of swinging with a ‘hollow posture’ versus ‘NO hollow’, by taking:

  • 100 swings with a ‘hollow posture’ (Global Spinal Flexion) – think Hunter Pence, and
  • 100 swings with ‘NO hollow’ (Spinal Lordosis) – think Derek Jeter…

 

Background Research

First I wanted to start off with the application of what a ‘hollow posture’ looks like in the MLB.  Look at the following hitters/pitcher, and note the similarities in the shape of their backs (or spine) before they begin rotation:

There are many more, especially in the 1960’s and ’70’s.  These hitters/pitcher either start with the ‘hollow’ or move into it before they start turning.

For the science, I recommend you read Dr. Serge Gracovetsky’s book The Spinal Engine.  I will go over a few talking points about the Posterior Ligamentous System (or PLS).  Think of the PLS as a connective tissue harness you’d use to scale down a large building.

In Dr. Gracovetsky’s aforementioned book, I’d like you to read under the subheading “Lifting While Lordosis Is Maintained” p. 82., and nd “Lifting While Lordosis Is Reduced” on p. 83.

I’m paraphrasing, but Dr. Gracovetsky says when the bend in the lower back is maintained (NO hollow), then we’re using a “muscle-predominant strategy”, and when the lower lumbar curve is taken out (hollow), then we’re tapping into the “muscle relaxation response”.

What Dr. Gracovetsky found in his research and study was that when a person picks something up from the ground that is heavier than we’re used to picking up, the back will round (hollow), muscles will turn off, and the PLS system will kick in.

You can experience the two systems (muscle v. ligament) by trying to see how long you can sit up straight in your seat…once your muscles get tired, then you’ll take on the hollow posture, letting the PLS take over.  This is why it’s so comfortable to sit slouched, and hard work to ‘keep your back straight’.

The reason for this ‘spinal safety net’ as Dr. Serge Gracovetsky alludes to, is to put the vertebrae of the spine into a safer position, also known as decompression.

My friend D @SelfDecompress on Twitter is doing just this with his clients.

One last note on the research…

CLICK HERE and read under the sub-heading “The Hitting ‘Governor'” in this HPL article about how our brain puts a limit on performance because of movement dysfunction.

Hypothesis

Based on Dr. Serge Gracovetsky’s research and study,  it is my forecast that taking on a ‘hollow posture’ before the turn, will increase average bat speed over not hollow.

I also add the same results is because of the information I included under ‘The Hitting Governor’ sub-heading in the aforementioned HPL article.

In other words, by hollowing the lower back, thereby decompressing the vertebrae of the spine, we remove ‘The Hitting Governor’ Effect, and allow the body to optimize turning speed.

Not to mention we make the swing safer for our rotating athletes’ bodies.

 

Baseball Hitting Drills Off Tee: ‘Hollow Posture’ Experiment

Equipment Used:

  • Backspin Batting Tee,
  • Zepp Labs Baseball app
  • Flip Camera,
  • My Android GS6 phone camera,
  • Baseballs, and
  •  33-inch BBB Bamboo wood bat

Setup:

  • We used the Zepp Labs Baseball app to gain swing data.  Our concern is for an apples to apples comparison between the two sets of 100 swings.
  • All swings for the baseball hitting drills off tee ‘hollow posture’ experiment were taken off a Backspin batting tee.
  • I stayed as consistent as I 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 plus two baseballs in front of the back marker.
  • The two tests in the baseball hitting drills off tee ‘hollow posture’ experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘Hollow posture’ was letter ‘A’, and ‘NO hunch’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “not being sufficiently warmed up” factors.
  • Throughout the baseball hitting drills off tee swing experiment, I was drinking a Strawberry Lemonade Gatorade (because I like it!) and a chocolate milk to replenish my body’s protein, sugars, and electrolytes during the 2-hour experiment.
  • I did an 8 exercise dynamic warm up before taking about 15-20 practice swings off the tee.

 

Data Collected (Zepp App Screenshot)

Baseball Hitting Drills Off Tee: Low Back Bend Zepp Swing Experiment

Please pay particular attention to the differences in Time To Impact & Attack Angle from the Zepp metrics…

 

Data Analysis & Conclusion

As you can see from the baseball hitting drills off tee Zepp screenshot and metrics above, the big differences between the two groups of 100 swings were the average:

  • Time To Impact: the ‘hollow posture’ was .004 seconds less than ‘NO hollow’, AND
  • Attack Angle: the ‘hollow posture’ was 4-degrees more positive than ‘NO hollow’

It looks like my baseball hitting drills off tee swing experiment Hypothesis was wrong in thinking there would be a boost to average bat speed with the ‘hollow posture’ swings.  However, there were three MAJOR benefits to swinging ‘hollow’:

  • According to Dr. Gracovetsky’s research, we can conclude it’s safer on the spine,
  • A DECREASE in Time To Impact, which buys a hitter more time to make a decision to swing, and
  • A more POSITIVE barrel Attack Angle, which puts a hitter into a better position to hit more consistent line drives.

Troy Tulowitzki Swing Breakdown: Stride Killing Bat Speed?

 

 

Question: Does Stride Length Kill Bat Speed?

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze whether Troy Tulowitzki’s longer stride increases or decreases bat speed.  Not just a longer stride, but I want to see the torso moving forward as well.

Background Research

Troy Tulowitzki had a wider stance in 2013.  In 2014, he’s adopted more of a narrow stance and a longer stride length.

Forward Momentum may be a new concept to hitting, but not to other explosive rotational athletes.  It’s also known as the Conservation of Linear Momentum and the Un-Weighting Principal.  The idea is that the hitter is getting a “head start”.  Other high level athletes using Forward Momentum:

  • Olympic Throwers (Discus, Javelin, and Hammer)

Hypothesis

I think the addition of forward momentum, or a longer stride length, will contribute to more bat speed because this gives the hitter a “head start”, making the body feel lighter while moving.  This allows the body to turn harder, and ultimately increase bat speed.

Troy Tulowitzki Experiment

Equipment:

  • Zepp Baseball app,
  • ATEC Tuffy Batting Tee,
  • Rawlings Official NCAA Baseballs,
  • Two yellow dimple baseballs,
  • Galaxy S3 phone camera, and
  • 33 inch, 30 ounce Pinnacle Bamboo bat.

Setup:

  • Feedback markers = my bat length, plus two baseballs
  • Distance from plate = end of the bat touching inside corner of plate, and knob of bat touching my mid-thigh
  • NO-stride stance was width of feedback markers
  • Forward movement stance was open, and feet set a little wider than shoulder width
  • Tee was set a baseball or two behind the front feedback marker, and tee height was about mid-thigh
  • 101 baseballs were hit using both the NO-stride and longer stride sessions

Data Analysis & Conclusion

Last 6 Swing Zepp Baseball app

NO-stride: last 6 batted balls (Zepp Baseball app)

  • 0.624 mph average bat speed increase with a longer stride.
  • Apex of bell curve for NO-stride swings ranged from 77 mph to 83 mph*.
  • With a longer stride, you’ll see the bell curve shifted, 81 mph to 85 mph*.
  • Three more 90 mph+ swings using a longer stride, in addition to increasing my Personal Record 2 mph.

*Based on six or more batted balls repeated in specific mph (bold typeface in the chart above)

 

Notes

Longer Stride: last 6 batted balls (Zepp Baseball app)

Longer Stride: last 6 batted balls (Zepp Baseball app)

  • Before the experiment I did a 7 minute Dynamic Warm-up.
  • I didn’t just increase my stride length, I moved my whole torso forward.
  • I began the experiment with the NO-stride swings.
  • I took a 20-30 minute break between the two sessions.
  • During the last twenty swings of the longer stride session, I hit five-of-eight 90 mph+ balls.

From the Zepp Baseball screenshots to the right, it’s interesting to note, my bat speed kept up, even increased with forward momentum and a longer stride.  In other words, I wasn’t as tired at the end of hitting over 200 baseballs.

Now that Troy Tulowitzki is using a more narrow stance and generating forward momentum with a longer stride, he’s able to increase his bat speed.  This may explain the surge in opposite field home-runs in 2014.
