I have had the last three and a half months off, and it has been great. I got to coach some baseball, do some training, catch up on sleep, see loved ones, start a few projects, and read a ton.
So suffice it to say I'm about to hit you with a ton of content. So get ready, because here comes 72 links:
From The Driveline Crew:
A Bill Hezel thread on thinking through a motion capture report to avoid identifying certain kinematics as always good or always bad.
Anthony Brady with a fairly deep dive into the sequencing of the legs and hips into footplant.
Matt Daniels with a great thread on how the arms work in the throwing motion.
Dean Jackson with a great thread that takes a different perspective on early torso rotation in the pitching delivery.
From the S&C Community
Eric Cressey reminds us why it's important to get outside...or at least take vitamin D supplements.
A great template for reaching out to someone for information or advice.
The guys at OnBaseU with a quick video of how to progress and regress some pelvic dissociation exercises.
Stephen Osterer with a thread on the need for, or lack thereof, hip external rotation ROM of the drive leg hip. And a tangentially related take on determining whether a mechanical tweak or ROM based intervention is best in any given scenario.
And yet another great Osterer thread detailing the importance of understanding why someone moves the way they do before implementing a corrective exercise, constraint drill, or mechanical change.
From Other Really Smart People
Eugene Bleeker dives into deceleration, interpreting biomechanical data, reciprocal motion, and biotensegrity in this epic tweetstorm.
Justin Stone with an incredibly clear, concise explanation of the baseball swing.
Justin Stone with a fun, simple explanation of angular vs. linear velocity.
Ben Brewster with a great video thread on holding the hinge on the drive leg.
A quick video demonstrating one way to practice using not-visual information.
MIT's Todd Carroll with a great thread on the college baseball recruiting process.
A great thread on teams vs. work groups.
Just For Fun
Watch out, Driveline is coming in hot with more fire. This article is on full signal biomechanical analysis, which is to regular biomechanical analysis what a video is to a picture.
A great Driveline article going into depth about a bunch of hitting stuff I thought I already understood but didn't.
Mike Robertson with a thoughtful article and a fresh take on the best way to use the post workout window to jump start recovery.
Randy Sullivan provides an incredible view on ways to improve the rehab process.
If you are training athletes - or yourself - and have limited resources, the article Assessment Process For The Low-Budget Program is a great place to start.
While most studies are looking at changes in the ball, fivethirtyeight took a look at the impact of spin on batted ball distance.
The Physics of The Gyro Pitch explains how gyro spin turns into side spin as the ball approaches the plate. It's very cool.
From James Clear's newletter:
"Some people need more focus. Others need to broaden their perspective.
Some people need to try harder. Others need to stress less.
Some people need to care more. Others need to let it go.
The secret is you are both people. The key is to know which one you are in this moment."
James Clear, author of Atomic Habits, put together this resource of links to incredible speeches.
For those who have never seen them, I highly recommend Daniel Pink's Pinkcasts. They're short (usually 2-3 minute) videos packed with interesting ideas and actionable takeaways. In this one he talks about Intellectual Humility.
A great article on mental toughness that quotes Eliud Kipchoge - he of the sub 2 hour marathon - and really fired me up while myself training for a marathon of the much longer variety.
Desirable Difficulty is an article on practice and learning, two important things that are difficult to optimize.
This Brad Stulberg article on achieving peak performance is short and to the point, illuminating the importance of knowing how to get started, how to keep going, and how to stop.
I'm not a parent, but this article on raising kids has many parallels to coaching.
This history of railroad tracks might make you question everything.
A NYT piece on the value of a liberal arts education.
Beep baseball is a baseball league for the blind, and it makes me so happy to know this exists.
Barton Smith and Pitching Ninja team up for the greatest video on fluid dynamics that a baseball nerd will ever see. And here's Barton's full presentation on the topic.
Episode 163 of The Perception Action Podcast goes into detail on constraints.
It seems like Ben Hanson gave one hell of a presentation at Slugfest. Check out his entire full-resolution slides from the talk here and the corresponding videos here.
Ryan Mossman’s incredible D1 D2, and D3 baseball statistical databases.
This Jaegersports week by week throwing build up for a professional pitcher is worth looking at for any pitcher as a template for what it actually takes to safely and completely prepare for a season from a throwing perspective.
A fun little web app where you enter your velo and spin rate to see big leaguers with comparable stuff.
