Identifying ER vs IR Dominance in Pitchers
Спорт
Physiology plays a major role in lower half pitching mechanics, and a movement assessment may only truly tell half the story when designing a throwing progression. Identifying the “ideal” lower half for an individual athlete is not as black and white as it appears, interpreting the gray area is the key to unlocking an efficient flow of energy up the chain.
-
In this breakdown, we not only define what IR (Internal Rotation) and ER (External Rotation) Dominance is, but provide the framework to connect the dots between a comprehensive movement assessment and what is happening on the mound.

I truly appreciate your ability to simplify an incredibly complex topic. As a pitching instructor I always look at those who have more experience and more credentials than I do. Iron sharpens Iron. Thank you for all that you do. I look forward to learning more.

Just from watching this video I can tell I am most likely ER dominant. I have always landed with my foot closed and this is probably why I’d spin out. Going to experiment a little with that thank you

I just figured out that I was internal dominant and never knew what externally rotating was and and now when I focused on it I feel way more explosive overall, although I felt explosive before but the numbers weren’t the best

I’m dutch and I’m having trouble understanding internal and external rotation can someone explain
In general internal Rotation is less mobile then external rotation. So at what degree do you speak of ER and IR dominance? And in which position do you measure? Is it a neutral hip or flexed in 90 degrees? Thx for the Great content
What platform you doing this presentation on? PowerPoint or ?
What are some good resources to learn how to asses an athletes structure
Can you go in depth on drills for ER dominance?

this looks very similar to Steffan Jones' Hip or Knee Dominance for Fast Bowlers in Cricket
diego castillo is just extremely rotational. Which results in a short stride and his arm slot is lower. He basically throws like he is hitting.

I watched your video on feeling the glutes and only now realise there are IR and ER. I can feel the glutes during IR but not really when throwing ER. Although i feel more stable keeping my shin vertical. What would you recommend to do to feel the glutes in ER

When you categorize an athlete as ER/IR dominant are you only referring to their drive/back leg? Or is it in reference to both hips?

Have you ever heard the term pushing the ball? If so how can I fix this? It’s not a fluid and it’s hurting my velocity.

Have an IR dominant teenage RHP who can’t seem to get front hip open when on mound. On his rotation lead leg from knee to ankle angles toward first base and when he lands this pushes or keeps his front hip closed. His finish is either pushing him towards third base or his foot and leg spin counter clockwise. Result is back hip and shoulder have zero separation. And he is in extreme contra lateral tilt and head pulls off towards first. Any tid-bits on where to start?

Jacob DeGrom is in the middle of the spectrum. The majority (maybe 60 or 70%) of pitchers don't cleanly fit into either category.
Is Edwin diaz an example of ir… ps you should do a video on his mechanics thank u

His front foot is an example of IR before landing. He gets into some crazy positions if you look at high speed side view video
Seems like a lot of driveline drills go against what tread athletics teach. Correct me if I’m wrong, but doesn’t driveline teach to lead with your elbow

That would be very hypocritical of them if they don’t, given how much those weighted balls help your arm externally rotate

They create they’re own drills that use the driveline plyos but not necessarily there drills/movements for drills
If I’m more Ir dominant, would increasing mobility and power with ER increase overall power

Please give this a read if you get a chance. Here is the Gospel (or, Good News): God says that we are sinners and that no amount of good works or behavioral changes on our part could ever make us holy enough to enter into Heaven. God sent His only begotten Son to be crucified on the cross to pay for our sins. JESUS CHRIST DIED FOR OUR SINS(ACCORDING TO THE SCRIPTURES), HE WAS BURIED, HE ROSE AGAIN THE THIRD DAY(ACCORDING TO THE SCRIPTURES) The instant you believe this, God knows it and He saves you. "31 And they said, Believe on the Lord Jesus Christ, and thou shalt be saved"(Acts 16:31A) The free gift (Romans 5:15) is based solely upon your trust in what Jesus did for you, and has absolutely nothing to do with what you do for Him. Ephesians 2:8-9, “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.” It is that simple to be saved 1 Corinthians 15:1-4 "15 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4 And that he was buried, and that he rose again the third day according to the scriptures:"(1 co 15:1-4) 0nce you are saved, you will always be saved. (Eph 1:13-14) Today, God is working through the dispensation of Grace; and all manner of practical doctrine for YOU today can be found in Romans-Philemon.
