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)
  • Olympic Shot Put
  • 4 X 100 meter relay sprinters
  • Circus Trapeze Artists
  • Lacrosse Players
  • Hockey Players

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 Collected:

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.

Baseball Swing Load: If You Can Bend Sideways You Can Gain 4-MPH Bat Speed

 

 

Question: Does a Slight “Downhill” Shoulder Angle Before Landing Boost Baseball Swing Load & Bat Speed?

In this baseball swing load “shoulder” angle experiment using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze what would happen to Bat & Hand Speed when we took 100 swings with a slight “Downhill” shoulder angle (about 8-10-degrees) versus another 100 swings with level shoulders.

The Feedback Lab parent testimonial about his 14 year old daughter Mia:

“Hey Coach,

It has been way too long but I wanted to share some information that happened yesterday. We are heading up to Chattanooga, Tennessee, the largest showcase in the southeast today. Yesterday was our last day to hit before the showcase and Mia was struggling with her power. We hit about 60-70 balls and Mia was hitting about 10% over the fence (she is usually 40%+). I was looking to make sure she was showing her number, which she was, hiding her hands, which she was, landing with a bent knee, which she was and etc., etc. It was getting late and we had to go and I told Mia she had only 6 balls left. I told her to show me her stance and I noticed that her front shoulder was equal to her back shoulder. I then told her to lower her front shoulder and raise her back one. That was the only change we made to her swing, Mia then hit the next 6 balls over the fence and 2 of them were bombs. I cannot believe the difference this one small change made.

Thanks,
Primo”

Baseball Swing Load: Miguel Cabrera WSJ Info-Graphic

Wall Street Journal Info-Graphic at: http://gohpl.com/1NFi8qi

The best resource for getting educated on spinal engine mechanics is to pick up Dr. Serge Gracovetsky’s book The Spinal Engine.  For a teased out version of this,

CLICK HERE for a post I did that compared the pitching delivery, hitting, and an overhead tennis serve using this “bending sideways” technique.

Another good book from multiple authors on the subject of spinal engine mechanics, locomotion biomechanics, and springy fascia, check out the book Dynamic Body by leading author Dr. Erik Dalton.

Also, here’s a great Wall Street Journal post about Miggy Cabrera titled, Miguel Cabrera: The Art of Hitting.  Check out what the illustration says in the middle of the red circle above…

 

Hypothesis

Based on the above baseball swing load experiment research and one of the other countless online hitting testimonials I get about “bending sideways” benefits, I think using a slight “Downhill” Shoulder Angle will boost Bat Speed at Impact by at least 3-mph, and Hand Speed Max by 2-mph.

 

Baseball Swing Load: “Downhill” Shoulder Angle Experiment

Baseball Swing Mechanics Experiment: Zepp Baseball App

Equipment Used:

  • Zepp Baseball app,
  • Tanner Tee,
  • Camera Phone
  • 33-inch wood bat.

Setup:

  • Tyler Doerner, my intern for the summer and a hitter in HPL’s The Feedback Lab, is a redshirt college Freshman.  He did the baseball swing load shoulder angle experiment.
  • Tyler broke the swing into two steps: 1) get to landing position, pause for 1-2 seconds, 2) then swing, to better control the shoulder angle during the tests.
  • So, there was an absence of forward momentum in this experiment.
  • The two tests in the experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  “Level Shoulders” were letter ‘A’, and
    “Downhill Shoulders” 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 Swing Load: Zepp Screenshot of Shoulder Angle Experiment

Look at the significant jumps in average Bat Speed at Impact & the Attack Angle…

Data Analysis & Conclusion

  • There’s a significant 4-mph JUMP in average Bat Speed at Impact with the “Downhill” Shoulder Angle.
  • Average Hand Speed Max only increased by 1-mph with the “Downhill” Shoulder Angle.
  • There was a small change in Time To Impact, in favor of the “Downhill” Shoulder Angle.
  • Not a big change in the Bat Vertical Angle at Impact.
  • And there was a significant 3-degree angle change in Attack Angle with “Downhill” Shoulder Angle.

Notes

  • We found a slightly bigger increase in average Bat Speed at Impact with the “Downhill” Shoulder Angle compared to my Hypothesis (4-mph versus 3-mph).
  • I thought there was going to be a bigger difference in Hand Speed Max, than how it turned out.
  • What was surprising was the 3-degree angle change of the attack angle.  A 10-degree Attack Angle is a typical line drive.  Once you start to get into the 15-20 degree range, you’re looking at more of a home-run launch angle.
  • The “Downhill” Shoulder Angle is actually something we’re working in Tyler’s swing.  He tends to let go of his angle a little too soon.
  • I find that before and after Ball Exit Speed readings with my local hitters who’re familiar with the “Downhill” Shoulder Angle, can increase from 1-3-mph when this it the only mechanic we’re working on.

The Bottom Line?

In this baseball swing load shoulder angle experiment, we can clearly see with the “Downhill” Shoulder Angle that there’s a significant 4-mph jump in Bat Speed at Impact, AND a surprising 3-degree boost in the Attack Angle.  The “Downhill” Shoulder Angle is a piece of what I call the Catapult Loading System.  The BIG-3 are:

  1. Downhill shoulder angle,
  2. Hiding hands from the pitcher, and
  3. For #3…

(‘Showing Numbers’ Experiment REVISITED) 

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

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

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

 

Background Research

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

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

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

Hypothesis

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

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

The big UPDATES to the experiment will be:

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

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

 

ADD Ball Exit Speed Swing Experiment

Equipment Used:

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

Setup:

Preston Scott: Showing versus NOT Showing Numbers

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

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

Data Collected (Zepp Baseball App):

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

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

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

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

Showing Numbers Day 1 & 2

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

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

 

Data Analysis & Conclusion

Starting with Zepp data analysis comparing the averages of averages:

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

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

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

 

Notes

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

Baseball Swing Mechanics Experiment: Squash The Bug Ineffective?

Question: Do “Squish the Bug” Baseball Swing Mechanics Depress Bat Speed?

 

Baseball Swing Mechanics Experiment: TylerD

Here are the two test swings from my intern for the summer, redshirt college Frosh, Tyler Doerner…

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze if the baseball swing mechanics “squishing/squashing the bug”, during the turn, increases or decreases bat speed.  The term “squishing the bug” means rotating the back foot, on the ground, during the turn.  Like you’re squishing a bug.

This can be a very sore subject, and hotly debated with a passion, in the Church of Baseball.  Surprisingly, it’s still widely taught throughout the lower levels.  Although a few images off the internet of effective swingers like Cano, Bautista, McCutchen, etc. will reveal “squishing the bug” isn’t what the best are doing.

So we wanted to test it…

My intern for the summer, redshirt college freshman Tyler Doerner did this experiment.  This post is for you Joe (you know who you are ;-)…

Background Research

One of the main objectives of whether to skip the foot, or keep it on the ground, has to do with transferring linear momentum, better known as un-weighting or forward momentum.  Check out these four HPL posts for a baseball swing mechanics background on this:

  1. Troy Tulowitzki Zepp Swing Experiment: Stride Killing Bat Speed?
  2. Ryan Braun: Common Mistakes Hitters Make #1
  3. Baseball Hitting Video: Gain Distance the Easy Way PART-1
  4. Perfect Swing Hacking with Forward Momentum (feat. Mike Trout)

Now, for you academics, CLICK HERE to watch a short 2-minute PBS video on Circus Physics and the Conservation of Linear Momentum.

So, after reading/watching the above videos and posts, we should be at a common understanding of Forward Momentum.

The next objective of “squishing the bug” versus “skipping the back foot” during the turn, boils down to allowing the body to transfer energy effectively.  This has to do with springy fascia in the body…

In Thomas Myers’s book Anatomy Trains, he talks about a cotton candy like springy material that the bones and muscles float it, and what gives muscles their shape called fascia.

Specifically in the book, he talks about the Front & Back Functional Lines.  CLICK HERE for a post I did on this, featuring Ted Williams and Matt Kemp.

In the following video, Thomas Myers explains this idea of Tensegrity, or Tension-Integrity.  There are compression and tension forces acting on the body at all times.  Within the body these two opposing forces are always searching for balance…

For a hitter, if the body moves forward, but the back foot and leg stays behind, then these forces don’t get optimally transferred from body to barrel to ball.  In other words, the backside gets “left behind”.

Hypothesis

Based on the above research, I think “squishing the bug” baseball swing mechanics will have a depressing effect on bat and hand speed because it doesn’t allow for full transfer of momentum and release of elastic energy in the springy fascia.

Equipment Used:

Setup:

  • Forward momentum was taken out of this baseball swing mechanics experiment by hitting from a 1-2 second pause at landing
  • Back two “baseball markers” were set at about 3 baseballs apart
  • The two tests in the experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  Say “squish the bug” was letter ‘A’, and “skipping back foot’ was 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):

Squish the Bug Baseball Swing Mechanics Experiment

There were significant changes in Average Bat & Hand Speed, Time to Impact, and surprisingly, the hitter’s Attack Angle in this baseball swing mechanics experiment…

Data Analysis & Conclusion

  • +8-mph difference in average Impact Bat Speed, siding on “Skipping Back Foot”,
  • +3-mph difference in average Hand Speed Max, siding on “Skipping Back Foot”,,
  • -0.019 difference in average Time To Impact, siding on “Skipping Back Foot”, and
  • +4-degree difference in average Attack Angle, siding on “Skipping Back Foot”.

 

Notes

  • I think the “Squish the Bug” baseball swing mechanics experiment results were overwhelmingly clear.
  • Tyler did not technically keep his back foot posted to the ground during the “squish the bug” tests, so there still was an element of un-weighting going on with his backside.
  • In which case, measuring Ball Exit Speed (or how fast the ball came off the bat) may have netted interesting data to consider, compared to Impact Bat Speed.  However, with the results with the other readings of Avg. Hand Speed, Time To Impact, and Attack Angle, I think we can put the “Squish the Bug” baseball swing mechanics myth to bed 😀
  • The data and results suggests that when a hitter “leaves behind their backside”, there’s a slowing down of forward momentum, and the body naturally decelerates because the springy fascia is forced to stretch, but not release.
  • Keep in mind what I call the Goldilocks Syndrome.  The back foot can skip too far (porridge too hot), and it can also not skip at all (porridge too cold).  We want the back foot to skip just right.

The Bottom Line?

In this “Squish the Bug” baseball swing mechanics experiment, “Skipping the Back Foot” showed a notable difference in average Bat & Hand Speed, Time To Impact, and the hitters Attack Angle.  I want to encourage you to tinker and test this for yourself.  The objective of these swing experiments is to put modern hitting theory to the test, literally.  We NEED to test based on data, not feelings.  Share these results with friends.
