Until dads say enough is enough, the carnage and heartbreak will continue Dr Brent Pourciau writes: “↓ If your elbow hurts after you throw hard, read this. Your elbow is the last link in the chain.” If Brent is talking about the kinetic chain the forearm, wrist, hand and finger joints follow the elbow joint action in the kinetic chain for pitchers. The order of joint action can’t change. ——— “The forearm muscles that sit over your UCL help resist the valgus stress of every pitch, like a seatbelt for the ligament.” Valgus stress has nothing to do with rupturing the Ulnar Collateral Ligament. Not understanding muscle action is at the root cause of all these unnecessary pitching injuries. ASMI refuses to understand muscle action. It’s made them a lot of cents. Five powerful pitching muscles attach to the Medial Epicondyle on the inner (baby finger) side of the elbow. These muscle arise above and attach below the elbow. When these muscles contract mioanglosly they move the forearm tightly against the upper arm. If pitchers do this, the Ulnar Collateral Ligament received zero stress. Valgus stress Most everyone has heard Brent and every other surgeon-loving guru talk about Max External Rotation or Layback. When pitchers go into MER the muscles on the outside of their elbow are contracting. This means the muscles on the insides of the elbow, the five Medial Epicondyle muscles, can’t contract. So Brent et al are teaching pitchers how to rupture their Ulnar Collateral Ligament This is not an easy kinesiological concept to understand but it is inexcusable that guys with letters after their name refuse to acknowledge Reciprocal Inhibition . All parents have to do is ask them about this. What parents refuse to understand is their sons can be as strong as King Kong and if they go into Maximum External Rotation, there is no muscle action that protects the Ulnar Collateral Ligament. If you do it my way, you’ll throw with more velocity. I prefer velocity over injury.
↓ If your elbow hurts after you throw hard, read this. Your elbow is the last link in the chain. The forearm muscles that sit over your UCL help resist the valgus stress of every pitch, like a seatbelt for the ligament. The catch: they fatigue. In collegiate pitchers, that muscular "seatbelt" strength dropped about 10% after 7 innings while the stress on the elbow stayed the same, so the ligament carries more of the load late in outings. After 100 pitches, high school pitchers needed about 24 hours to fully recover that stability. To be straight with you, the research isn't settled on how much forearm strength protects the ligament itself. What it does build is a forearm that holds up longer late in an outing. So yes, do these: 1️⃣ Add them to your pre-throw warm-up 2️⃣ 2 x 15 reps each 3️⃣ Slow and controlled. Not fast. But I wish it was this simple. Arm care alone isn't enough to keep you healthy. How you throw decides how much load your elbow takes. In adult pitchers, rotating the trunk too early was linked to higher elbow valgus load. No band routine fixes timing. Submit your video to MechanicsDNA Mini at topvelocity.org and we'll find the real problem. If something is already sore, that calls for an assessment from a medical professional, not a warm-up. — Dr. Brent Pourciau, TopVelocity #pitching #baseball #armcare #elbow #ucl #pitchingvelocity #TopVelocity

I'm always trying to learn about things we can find outside the strength and conditioning industry that may in some way benefit the way we coach athletes. Today, I've got an example: ericcressey.com/optimist-str…

Brent Pourciau PhD writes: 1️⃣ “LINEAR: drive your body down the mound” This is what the Japanese call ‘translation’. So, I assume the dads of #BBTrumpland have bought in. I won’t bother to ask in what direction the object of interest, the baseball, is heading when pitchers translate. 2️⃣ “ROTATIONAL: hips open first, shoulders wait, trunk fires” This is why pitchers can’t get their pitching foot very far from the rubber. Dads get a twofer: 1. less velocity 2. Injuries Gotta keep dad happy 3️⃣ “LINEAR: the front leg blocks and the arm whips through A careful reader will note Brent is justifying bringing the CoM to a screeching halt by telling the unwashed their arm will have a ‘whip’ effect. Back in the day, front foot block was likened to a speeding car hitting a wall. The image of a body whipping through the windshield was gruesome but effective. Then a book learned PhD came along and said the body actually slowed down once the car hit the wall.

Great congratulations to Bryant Ogando. Whether on a mound where pitchers pitch or flat ground 90 MPH is special. As my readers know, to maximize your release velocity, albeit safely, my foreign tool, Coach Isaac Newton, requires straight line force. When my readers see the elbow on the wrong side of the pitcher’s body they know the pitcher will transcribe an arc on his path to release. While this reduces potential velocity it does cause injuries. ASMI has to eat

The drills are supposed to teach the skills. The Japanese (Yamamoto) are starting to at least bastardize my heavy ball throws. Once the foreigners start embracing science and modernity Brent et al will be forced to dump ASMI and embrace velocity over injuries. A tough stretch ahead for the dads of #BBTrumpland …..starting tomorrow night. When pitchers start wrong….it ends bsdly
Don't finish with the drill. Drill → throw → review. The drill only counts if it shows up in the throw. Film both. Watch the whole movement. Then slow it down and check the order: hips → chest → arm.

What gets measured gets managed. I agree with Dr Pourciau’s numbers. Without skill, the numbers won’t matter. But you have to check the boxes.

I can see why Ahmad loves Eric Cressey. This drill has nothing to do with pitching (or batting) And won’t help Cam Schlittler engage his Latissimus Dorsi.

Dr Brent Pourciau writes:ll “Manuel's front leg is where his velocity comes from. 🔥” While not addressing my claim that Brent’s pitchers do not accelerate the baseball with their legs, this is Brent’s answer to my charge The key word here from Brent is velocity. My readers will note I use the word Acceleration. I’m not saying Brent is mendacious. He simply missed a couple of classes at science school. Brent continued “That block is the brake. The lower body stops, and everything it built whips into the trunk and arm.” The key word here is ‘block’. Velocity is how fast an object moves in a specific direction, while acceleration is how fast that velocity changes over time. Coach Newton is interested in Accelerating the baseball until it gets to its final velocity release. F=MA. A is Acceleration. Dr Pourciau loves to talk about the kinetic chain. Acceration is the foundational principle behind the kinetic chain. Each joint sequentially conserves the velocity from the prior joint and adds (accelerates) to it. Brent’s use of the word block is apropos. We can easily see the Center of Mass stop moving forward at front foot block. In order to keep the baseball moving forward at some velocity Brent’s pitchers have to bend forward at the waist. If we tracked the rate of velocity change it will go down. Brent counters that the pitcher will whip the baseball forward. I use the term force -couple quite often with my Inner Circle instead of whip. Brent does not understand how force-coupling (whip) occurs in the baseball pitching motion. Force-coupling is oppositely directed forces on either side of a fulcrum. Dr Pourciau has to describe these oppositely directed forces and the fulcrum. When you block the COM from continuing forward through release, the Tate of the change in velocity (acceleration) goes down. But let’s be fanciful and say velocity goes up. Then Brent has to explain the destroyed lower backs for the 99% that don’t get paid. The Dowling in the study Brent cites is #BBTrumpland’s gift to the DEI crowd. I’ll let it go at that…for now. In a study of 322 pro pitchers, the hardest throwers straightened their front knee 17° from foot strike to release. The slower group: 5°. (Dowling et al., Sports Biomechanics, 2022)
Manuel's front leg is where his velocity comes from. 🔥 Watch it land and bend… then BLOCK. 134° → 153° from foot plant to release. That block is the brake. The lower body stops, and everything it built whips into the trunk and arm. In a study of 322 pro pitchers, the hardest throwers straightened their front knee 17° from foot strike to release. The slower group: 5°. (Dowling et al., Sports Biomechanics, 2022) Pause your pitcher's video at release. Is his front knee still bent, or did it block?

As we head to the polls, let’s not forget Israel-first @BillAckman , the Brit @elonmusk and their flunkies across #BBTrumpland support the buffoon that refers to these Americans as “suckers and losers”.
On October 31, 1972, Navy SEAL Michael Thornton faced a choice few could make. Amid a brutal ambush, his team was withdrawing when he learned Lieutenant Thomas Norris had been hit and left behind. Without hesitation, Thornton sprinted back through enemy fire, shot two enemy soldiers, and lifted his unconscious officer onto his shoulders. Then he carried Norris 400 yards to the water and swam for two hours through open surf, under relentless fire, refusing aid until his comrade was safe. For his extraordinary courage and unwavering loyalty, Thornton was awarded the Medal of Honor - one of the only men in history to save a fellow Medal of Honor recipient. His actions embody the SEAL creed: no one left behind. 🇺🇸

Dr Brent Pourciau writes: “Velocity starts in the legs” I’ve got to believe there is a dad in #BBTrumpland that would love to shut me up. All he has to do is show me a pitcher who uses his legs to accelerate the baseball. Dads used to show me pitchers that use their legs to stand on the mound. That doesn’t count. So my unanswered challenge remains. The dads of #BBTrumpland hope Fransy Bosch will bail them out. Not gonna happen
Every pitcher who made it has a YES slide. 👇 YES, he got cut. BUT, he didn't quit. YES, he's the smallest guy on the team. BUT, velocity starts in the legs. YES, the radar didn't move. BUT, he filmed his delivery and found the leak. YES, his arm hurt every weekend. BUT, he stopped pitching for 3 teams and built his body. YES, he got pulled in the 2nd inning. BUT, he asked what to fix. YES, the scouts left early. BUT, next year they stayed. Being behind isn't the end of the story. Not having a plan is.

Velocity. I know Specificity is a difficult concept to understand but if you want to throw a baseball with more velocity and spin next Spring, you have to Overload the muscles, bones, ligaments and tendons associated with pitching and pitch baseballs as hard as you can from pitching mounds this Fall and Winter.

Dr Brent Pourciau writes: “Pause your pitcher's video the moment the ball leaves his hand. Look at his chest.” Fair enough but I look at the front foot. If the front foot is ahead of the front knee, a clear violation of my foreign tool Isaac Newton’s 3rd Law, then the pitcher will have to bend forward at the waist. Done enough times, the intervertebral disks in his lower back wear away enough to start irritating the nerve roots that serve his Sciatic nerve. If dads want to see Skipster suffer, bending forward at the waist will do it. And yes, not moving the COM forward through release reduces release velocity. I prefer velocity over injuries. Pitchers must wait until after they rotate to lean. Pitchers must stand tall and forwardly rotate their entire pitching arm side of their body over their glove foot and down their Acromial line. Two PhDs…..one choice.
Pause your pitcher's video the moment the ball leaves his hand. Look at his chest. Is it out over his front knee? Or is he standing tall, leaning back? If he's upright, he stopped driving forward too early, and the arm has to make up the difference. Hard throwers finish forward. Front leg firm. Chest over the knee. The research: 1️⃣ When the same pitcher threw his hardest fastballs, his trunk was tilted further forward at release (Stodden, Fleisig, McLean & Andrews, J Appl Biomech, 2005). 2️⃣ In the lab, the farther pitchers threw on max-distance long toss, the less forward trunk tilt they had at release (Fleisig et al., JOSPT, 2011). Try it tonight: film from the side, pause at release, and check the chest. Want a second set of eyes? Comment THROW and I'll send you a free arm risk assessment. No call, no pitch.

Because of the leverage position of the patellar tendon I oppose ATG squats. With baseball accepting Dr Mike Marshall’s advise to catch from one knee I don’t see the need for squatting with weight we used to make an argument for with baseball catchers. I am not opposed to ATG body squats. For most body weight squats should be able to give the vast majority of people the leg strength for everyday life. Wall squats are a good exercise, especially for those with high blood pressure. Weight lifters obviously can squat with weight but take a look at Ronnie Coleman. With that said, for the vast majority that don’t listen to science and modernity this is an excellent article on squatting with weight. If you lift weights it is critically important to do it correctly.

In this infomercial, like most doyens of #BBTrumpland. Eric Cressey, cites the obligatory foreign tools; in this case the Russians. Eric tells the hapless dads of #BBTrumpland that to get ready to train specifically we must train Skippy generally (GPP). But wait, the general exercises have to be specific. It was way too easy for the Rays and Brewers. Way too easy
Modern General Physical Preparation (GPP) approaches have often drifted into an excuse for one-size-fits-all programming. Just because it's general doesn't mean it shouldn't be very calculated! Learn more in the latest podcast: ericcressey.com/csp-elite-ba…

We do NOT have a common flexor tendon. The 5 muscles that arise from the medial epicondyle on the inside of our elbow are 5 separate and distinct muscles. Only one of these muscles flexes the four fingers.
If you’ve ever wondered why pitching mechanics change seemingly out of nowhere here is a quick look at it happening in real time with Jacob Misiorowski…. There are 5 muscles of the common flexor tendon and 5 muscles of the common extensor tendon situated at the connection between the upper arm and forearm…. Each individual muscle works with a specific set of finger flexor muscles to move the arm and hand. If the muscles holding the baseball change, so do the muscles moving the arm. There is a change to the kinetic chain at every joint in the body so the whole body will move differently. It’s all automated, you can’t change how the body produces motion no matter what your intent or “cue” is and it’s all determined by what muscles are contracting in the hands. Watch how different his right arm moves when he comes set. Watch how different his right shoulder moves in relation to his arm as he begins his throwing motion.

How daddy Murphy can look at this and still let his ‘son’ Jacob pitch like this astounds me. When pitchers start wrong….it ends badly Nice video
An interesting posture adjustment by The Miz this year was starting his delivery in more flexion. By starting in a more flexed posture, he gives himself more room to operate in spinal flexion before transitioning into spinal extension later in the delivery. @Ty6Ryan
