Impulse = Force x Time

Impulse continues to be a buzzword in S&C - and with good reason. It should be noted however that due to its temporal component, a high impulse does not always equate to a better performance.

All things being equal, we'd pick Athlete B as our teammate!

I realize I post a lot about segmental energy flow during pitching but we've also been studying it during hitting. @PLNU_MSKIN student Avery Avina is leading the charge (pun intended) on mapping generation, absorption, and transfer through the kinetic chain. ⚾️

Subconscious 🧠 >>> conscious 🧠

Elite athletes that achieve mastery exhibit unconscious competence - their actions are truly subconscious. The “yips” happens when conscious thoughts override subconscious control (conscious competence phase).

Quotes in article are incorrect.

[FanGraphs Baseball @fangraphs]

As Jose Altuve battled throwing issues in the ALCS, Dusty Baker called upon an old friend for some help: Tom House. @DavidLaurilaQA talked to House about the yips and how to solve them. https://t.co/kEkAlKfNVA

Huge insight here that’s worth emphasizing again. Averages mask variability within and between players. Functional variability is a critical to being successful in dynamic environments. Understand the variable elements (resulting plane/posture) and the stable ones (rotation/load)

One of the best in the business. Learned so much about being a complete hitter with Reggie over the years. Great mixture of playing and coaching experience and willingness to discuss swing mechanics. Incredibly humble man given his many accomplishments.

Hey @MLB @MLBVault We saw 61yr old Julio Franco get some love today. How about some love for 74yr old 7x All Star, Legend, Reggie Smith? Still hitting lasers.
A true master teacher! 🙏

Great stuff. I view #3 as redundant to #1 & #2. Compromised anterior pelvic tilt (#1) restricts ability to rotate efficiently through middle ➡️ knee-driven extension & ➡️ spine compensation. Kinetic link between left hip & foot/arches in both tells story 🧠 knows 3D not planes

A prominent theory in #neuroscience hypothesizes that the #CNS generates muscle activity to simplify #motorcontrol, so that muscles with similar task actions are controlled as a single functional unit. Our results do not support this hypothesis! A thread. https://t.co/PelMKq78cD

On deck: Induced acceleration (IAA) and power analyses (IPA) of pitching in collabo with @WakePitchingLab using a full-body IAA plug-in by Tom Kepple of @cmotioninc. Here’s an IPA profile of segments mapped to its direct contribution to the induced power of the arm (1/n)

[square1system @square1system]

The brain perceives ground reaction force (GRF) as either safe/unsafe for every joint action.

The brain generates patterns (motor control) from GRF-safe actions & works around GRF-unsafe actions.

Resetting the brain’s unsafe perceptions back to safe optimizes motor control.

My (seemingly) monthly (most-likely in vain) drum-beating against the continued ignorance of some folks on the complexity of speed, and the methods we employ to improve it:

How long does applied sports science “remain in business” if it persists with group-based analyses that have limited application to individual athletes?

[Rufus @RufusPeabody]

This is a generalization, and it may be wrong, but I think the ease of doing complex machine learning has made the new generation worse at predictive modeling. It's just "plug it into a neural net" now, at the expense of critical thinking and problem solving ability.

[Patrick Cherveny @BEST_Perform]

@ThatGuy__Kai @SuccessLvsClues Congrats Kai! Now that Avery’s all set, just need to get you a @whoop to keep you primed.

@MaxDutto_ Sorry - wasn't meant to be a criticism. I got where you were going and your summation was correct. Was just pointing out the breakdown in connection. Should have let you post it first. Great stuff - keep it coming!

[Patrick Cherveny @BEST_Perform]

@MaxDutto_ The answer was in your first GIF. Donaldson's lead arm is not connected to this shoulder line and thus his spine plane. Bryant's lead arm is more connected.

(Also realize inferring too much 3D info from 2D images taken at different locations is not ideal).

[Patrick Cherveny @BEST_Perform]

@QuantTee @dan_aucoin13 What exactly do you mean by this? Blast is using positional vector path of the sweet spot of the bat from impact frame to prior frame. Any pitch location difference in attack angle is a real measurement.
