Why does throwing 75% of your top velocity take far less than 75% perceived effort? Here @cory_wilder and I discuss a potential explanation from a physics perspective. (Thread 🧵) 1/

These guys have had a front row seat working with some of the best coaches, player development, and scouting groups, in both the professional and amateur baseball/softball spaces. Fired up to listen to them dropping insights on what they've learned! @KyleAttl @JoeTourville1

Looking forward to sharing what we’ve learned the last 7 years with Blast. - Metrics - Training - Application of data - Coaching styles - Scouting - and everything in between MLB all the way to youth

Awesome work on the cutting edge of weightlifting biomechanics with elite athletes! Bringing together the whole picture for athletes competing at the highest level!

Motivated by student presentations on processing and visualizing data in my biomechanics class I decided I needed to Level Up my coding skills, too, which led to this video on weightlifting biomechanics (of course!). Thoughts on what to change or add? Also, h/t @JacobHowenstein

Last research project of the summer: analysis of flow/transfer of linear momentum in weightlifting. Takeaways: large increase during 1st and 2nd pull, continuous increase during transition, and efficient transfer from legs through torso to arms & bar ... all = 2xBW clean.

@MUSportScience @BenDrury_HU @BenDrury_HU The is a custom project developed spefically for weightlifting performance analysis. Written in Python and primary relies on opencv and numpy for the computer vision tracking and analysis.

For anyone who attended the #weightlifting #biomechanics session during last week's @ISBSOFFICIAL mid-year symposium and didn't get enough weightlifting content, have a look at this great thread (and give @JacobHowenstein a follow)!

Weightlifting Training Progress in Data. Training hasn’t been as consistent as it should be but still made quite a bit of progress over 3.5 months after starting to train again. On the left is the max lift from my initial session at 105 kg and the right is 120 kg from 12/3.

And even better than data is hitting this 128 kg Snatch a couple weeks ago, only 3kg under my all-time best.

A big part of this was a better pull under the bar (third pull). Less overall horizontal movement (jumping back), slightly quicker turnover, and moving my body straighter down instead of out and around, all contributed to a made lift even with less max bar height than before.

Last piece of my initial assessment: Jerks! Definitely my weakest lift and the limiter on my overall Clean and Jerk. These felt especially rough after not really going overhead for ~6 mo Here is what we see in the data... (1/6)

The training prescription: 1. Lots of overloaded jerk dips to build the movement pattern and core stability (shown). 2. Behind the neck jerks to develop the feel of a straight dip/drive and get more comfortable with a lockout potion directly over my shoulders. (6/6)

Echoing @CAthletics, The short front foot and limited 'push under' is probably a product of the first two problems (bad dip, insufficient drive) and will hopefully improve as a result of cleaning up the other two issues. (5/6)
