Bust bat drag hitting experiment featuring JD Martinez!  Discover how to fix a disconnected swing and get rid of dragging back elbow with the scap load for baseball or softball hitters.  Do “Ball Under Back Arm Drills” build a quick swing?

In my humble opinion, NO.  Unless, and in the case of curing bat drag, the hitter is pinching the rear scapula in towards the spine with the ball underneath the back arm.  But then again, for that, why would you want the ball there in the first place?  A quick and consistently powerful swing comes from taking ALL slack out of the system, and the scap load is part of that formula.

Boost “Top Out” Bat Speed By “Hiding The Hands”, Like JD Martinez…

 

 

Question: Does Hiding the Hands Increase Bat Speed versus NOT Hiding Them?

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze if hiding the hands from the pitcher prior to stride landing boosts bat speed, over not hiding them.  Some may call this the “Scap Row”.

And we’ll see what proper baseball hitting mechanics look like with MLB Player of the Week (July 6th) JD Martinez of the Detroit Tigers.

My intern for the summer, red-shirt college freshman Tyler Doerner did the experiment.

Background Research

Most hitting instructors may call this the Scapula Row, or Scap Row for short.  “Hiding the hands” is essentially the same thing, but is a much more sticky coaching cue.

“Hiding the Hands” has to do with loading the springy fascial material in the body.  Without this springy fascia your bones and muscles would drop to the ground.  It’s what gives muscles their shape, and what the bones and muscles ‘float’ in, according to Thomas Myers in his book Anatomy Trains.

“Hiding the Hands” also allows a hitter to be in proper baseball hitting mechanics to achieve high angular velocity early in the turn.  This has to do with the Conservation of Angular Momentum.  Achieving high angular velocity, early in the turn, is critical to Time To Impact and covering more plane of the pitch with the barrel.

Hypothesis

Based on the above research, I think proper baseball hitting mechanics, a la “Hiding the Hands”, from the pitcher (pre-turn) will have a big impact on bat speed versus not hiding them.  I think results will be similar to what the “Showing the Numbers” Experiment revealed, where we saw an average bat speed increase of 6-mph over 200 swings.

 

Proper Baseball Hitting Mechanics: JD Martinez “Hiding Hands” Experiment

SwingAway Pro XXL Model

Tyler uses a SoloHitter in the Experiment. The SwingAway Bryce Harper is swinging on is similar.

Equipment Used:

  • Zepp Baseball app,
  • Solohitter (like the SwingAway which I like better),
  • Camera Phone, Coaches Eye app, and Tripod, and
  • 33 inch, 30 ounce wood bat.

Setup:

  • Forward momentum was eliminated in this experiment, and hitting from a 1-2 second pause at landing
  • First 100 baseballs were hit “NOT Hiding the Hands”
  • Second 100 baseballs were hit “Hiding the Hands”
  • There was no break between tests because Tyler was trying to beat the rains coming

 

Data Collected (Zepp Baseball App):

Proper Baseball Hitting Mechanics Zepp Experiment Results: Hiding the Hands

In this proper baseball hitting mechanics “Hiding the Hands” Zepp Experiment, see how “Hiding the Hands” slightly won out in Bat & Hand Speed, and Time to Impact rather than “Not Hiding the Hands”…

Data Analysis & Conclusion

  • As you can see, “Hiding the Hands” beat almost every category…
  • On average, 1-mph change in Bat Speed,
  • On average, 1-mph change in Hand Speed, and
  • On average, .005 change in Time To Impact.

“Hiding the Hands” didn’t have a significant jump in bat and hand speed, or Time To Impact than “NOT Hiding the Hands.”  But there was a difference in top-out bat speeds:

  • Top-4 “Hiding the Hands” bat speeds (in mph): 85, 84, 84, and 82.
  • Top-4 “Not Hiding the Hands” bat speeds (in mph): 82, 81, and the rest were less than 79.

So, top out bat speed increased by 3-mph, and there were consistent higher bat speeds with “Hiding the Hands”.

Notes

  • The results of the proper baseball hitting mechanics “Hiding the Hands” Zepp Experiment may have been skewed because Tyler didn’t take a break between tests.
  • The following experiments will be using what one of my readers and motor learning and performance researcher Brad McKay suggests, which is counterbalancing the experiment.  Essentially it’s breaking experiment swings into 25 swing blocks, and ordering them a certain way.  For example, “Hiding the Hands” would be block “A”, and “Not Hiding the Hands” would be block “B”.  The 200 swings would be broken into 8 blocks and ordered accordingly: ABBA BAAB.  As Brad McKay says, “The issue with not counterbalancing is that you don’t actually know the effect of time because it is confounded with condition. In other words, you might always do better on the second block of 100 because of a warm-up decrement or a practice effect.”  Thank you Brad for the experiment tip!  We’ll do better next time 😀
  • About JD Martinez…this FanGraphs.com link titled, “JD Martinez on His Many Adjustments” is a great example of players today opening their eyes to how the body really moves, and not what some talking head thinks.  Basically, JD Martinez subscribed to swinging “down on the ball” until he got injured in 2014, I believe.  Then he started analyzing teammates’ and opponents’ swings that were crushing the ball, and found out they weren’t swinging down at all.
  • A week or two after the 2015 All Star break, according to FanGraphs.com, JD Martinez had 27 homers.  His season high before that? 23, in 2014.  To me, JD Martinez is a big slugger at 6’3″, 220-pounds.  But when big sluggers do small slugger things (like being more effective with mechanics), even bigger things can happen.  JD Martinez does a great job of “Showing his Numbers” and “Hiding the Hands”.  This compresses the springy fascia material in the body.

The Bottom Line?

In this proper baseball hitting mechanics “Hiding the Hands” Zepp Swing Experiment, “Hiding the Hands” doesn’t seem to give a hitter a significant jump in Bat and Hand Speed, or Time to Impact.  But definitely an increase nonetheless.  But what using proper baseball hitting mechanics, like “Hiding the Hands”, does appear to do, is boost top-out bat speeds.  AND, make those top-out bat speeds repeatable.

Bust bat drag with Camwood heavy bat?  Simple baseball and softball hitting mechanical drill to help get rid of, cure, and fix causes of racing back elbow.  I probably wouldn’t look to fixing bat drag with a heavy bat like Camwood in the beginning.  It’s mainly caused by a mechanical and over-rotation issue.

Baseball Hitting Drills for Little League: Jace Bat Drag

Look at my 11u hitter Jace’s racing back elbow, and the fix a week later. On the left side, he weighed in at 68-lbs, and right before our session, hit his first official homer distancing 180-feet!

Question: Does ‘Top Hand Finger Pressure’ Effect Bat & Hand Speed, and Time To Impact versus Keeping the Hands Loose? (Pre-Turn Hand Tension Revisited)

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to revisit a past experiment I did titled “Babe Ruth Reveals Hand Tension?”  And analyze whether having relaxed hands OR ‘finger pressure’ affects Zepp metrics.

Growing up, I was taught baseball hitting drills for Little League – which are still being taught, that loose hands are quick hands.  Modern research REVEALS that may not be the WHOLE story.

I wanted to revisit the previous ‘Babe Ruth experiment’ because in that test, I wasn’t actively holding the finger pressure through impact.  In this experiment, I will be.

In the Conclusion of this post, I’ll also give a couple examples of my hitters who were suffering from really stubborn bat drag (one for over 1.5 years), and how we used ‘finger pressure’ to correct it within 1-2 weeks.

Background Research

In the Babe Ruth Pre-Turn Hand Tension Zepp swing experiment, I used the following Research links:

  • Pavel Tsatsouline Tim Ferriss podcast revealing how the hands can be used to recruit more muscle tissue and connect larger areas of the body,
  • Homer Kelly’s book The Golfing Machine went into describing one of the four power accumulators in the golf swing, and
  • Thomas Myers’s book Anatomy Trains, and how Front Arm Fascial Lines are responsible for connecting what an explosive rotational athlete is holding in their hand(s), with the other springy fascial lines inter-weaving throughout the rest of the torso and body.

I also wanted to point out that a few months after publishing the ‘Babe Ruth Pre-Turn Hand Tension’ experiment I met Lee Comeaux, now a good friend of mine, who is a professional golf instructor out in Texas.  He’s been studying Thomas Myers’s book Anatomy Trains for over a decade now.

He simplifies the concept we now call top hand finger pressure.  So THANK YOU Lee!  CLICK HERE to visit Lee’s (Roy) YouTube channel.  And by the way, Lee has a 13u daughter playing fastpitch softball in Texas, and last time I heard she was hitting .800 using the same principles we talk about here.

So yes, this works for both fastpitch and baseball hitters!

Please watch the following interview with Thomas Myers titled, “Tensegrity Applied To Human Biomechanics”:

 

 

  • Defining tension & compression Forces (0:10)
  • Applying tension to the structure makes it stronger and more stable (5:55)
  • Applying tensegrity to the human body and tightening up as a benefit to taking on impact (12:35)

I’ve also heard Thomas Myers talk about synovial fluid in our joints.  It’s our lubrication system.  And it’s liquid, between the joints, when we’re relaxed…in the above video, he called this “adaptability”.

However, when we catch a ball in a glove, for instance, we squeeze our hand around the ball turning the synovial fluid to a solid state.  This concept becomes important when we’re talking about ‘finger pressure’ when hitting.

I tell my hitters it’s the difference between the ball feeling like it’s hitting a cinder block (the bat), or a wet pool noodle.

Hypothesis

Baseball Hitting Drills for Little League: Zack Racing Back Elbow Fix

This is my Sophomore in H.S. Zack and his racing back elbow BEFORE & AFTER. This was a 1 week fix employing ‘finger pressure’.

I’m a little biased in this experiment because I’ve seen the research AND how this has worked miracles with my own hitters employing ‘top hand finger pressure’. However, I wanted to conduct another formal experiment comparing the  following Zepp metrics:

  • Bat Speed at Impact,
  • Hand Speed Max,
  • Time To Impact,
  • Barrel Vertical Angle at Impact, and
  • Attack Angle…

…between the two swings.  Whereas the aforementioned ‘Babe Ruth Pre-Turn Hand Tension‘ experiment I held the hand tension before the turn, then let it go.  This experiment I’ll be keeping top hand finger pressure from the moment I pick up my front foot to stride, to all the way through impact.

I predict, by using ‘top hand finger pressure’ longer, we’ll see an effective jump in all metrics rather than the conventional of ‘loose hands are fast hands’.  I also predict holding finger pressure longer will be more effective than the previously mentioned experiment metrics for Pre-Turn Hand Tension.

At the end, I’ll show how ‘finger pressure’ has STOPPED bat drag in two of my hitters at the Conclusion of the experiment.

 

Baseball Hitting Drills For Little League: ‘Finger Pressure’ Experiment

Equipment Used:

Setup:

  • We used the Zepp Labs Baseball app to gain swing data.
  • 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 for Little League ‘finger pressure’ experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘Finger pressure’ was letter ‘A’, and ‘loose hands’ 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.
  • On the finger pressure swings, I used top hand bottom three finger pressure only, which consisted of tightening up the top hand bottom three fingers (pinky, ring, & middle) from the time I picked my stride foot up, to all the way through impact.  The bottom hand was doing what I call the ‘butterfly grip’…tight enough to keep a butterfly from getting away but not too tight to crush it.
  • Loose hands consisted of trying to maintain a ‘butterfly grip’ throughout the whole swing.
  • Throughout the baseball hitting drills for Little League swing experiment, I was drinking a Lime Cucumber flavored “Pepino” Gatorade (very good btw) 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 in this baseball hitting drills for Little League experiment before taking about 15-20 practice swings off the tee.

Data Collected (Zepp App Screenshot)

Baseball Hitting Drills For Little League: Finger Pressure Zepp Experiment

Notice the slight change in bat and hand speed metrics, AND the difference in Time To Impact…

 

Data Analysis & Conclusion

Baseball Hitting Drills for Little League: Bat Path

You can clearly see the negative Attack Angle.  This was a finger pressure swing.

  • Using ‘Finger Pressure’ gained an average of 1-mph Bat Speed at Impact
  • Using ‘Finger Pressure’ gained an average of 1-mph Hand Speed Max
  • Using ‘Loose Hands’ decreased Time To Impact by a whopping 0.017 (17/100th’s of a second)
  • Bat Vertical Angle & Attack Angle showed no differences between the two swings.

These were interesting findings in this baseball hitting drills for Little League finger pressure Zepp swing experiment.

My Hypothesis proved correct in that we saw an increase in average Bat Speed at Impact and Hand Speed Max employing ‘finger pressure’, however it wasn’t a huge change.

Also in my Hypothesis, this experiment didn’t turn out more effective for finger pressure than it did for Pre-Turn Hand Tension (PTHT) in the Babe Ruth Experiment, where I gained an average of 3-mph Bat Speed at Impact using PTHT.

You’ll notice the major decrease in Time To Impact using the ‘loose hands’ method.  Excluding the racing back elbow bat drag hitter, from these results and the Thomas Myers research, we can say using a hybrid of the two methods…loose hands at the start of the turn, and finger pressure slightly pre-, at-, and post- impact would be more effective than not.

On the contrary, for the bat drag hitter with a racing back elbow issue, I think finger pressure MUST be used before the turn happens because these hitters evidently have a ‘fascial connection’ issue between what they’re holding in their hand, and their turning torso.

In other words, they may not intuitively use finger pressure like other hitters without the racing back elbow issue.  So this would be one of the smarter baseball hitting drills for little league.

Besides, according to the Zepp app Time To Impact Goals for Pro hitters are right around .140 anyway, so my .131 with finger pressure is still more effective.

One last thing to note, coming from my experiential knowledge in working with my hitters, I consistently see a 2-3-mph boost in Ball Exit Speed when using finger pressure versus NOT in one 45-minute session.

This just means I’ll have to REVISIT this baseball hitting drills for Little League finger pressure Zepp swing experiment again, but collecting and comparing Ball Exit Speed data.
