My baseball paper looking at impulse generation for each leg in baseball pitching is now open access! tandfonline.com/doi/full/10.10… @Biomec_Baseball @sportsbiomechj

I'm seeing a lot of MLB orgs adding Biomech roles interpreting the data for coaches & players. They also seem to be lower level roles. For me this is backwards. Applying Biomech to the individual is the hardest bit, it requires the most knowledege and experience, not the least

Happy to talk about learnings from my dissertation work and beyond! Thanks for the opportunity

Ah yes, Artificial Intelligence! Bringing you new elite features such as: - filtering - drawing - charts this new technology must be stopped!

@kww_BOS Are we measuring hits by planck length yet

@KaneJMiddleton @drivelinekyle @DrivelineBB This could be better improved with swing duration, but even if so, it just gets you the average acceleration. Perhaps they are looking for peak acceleration? Either way, it’s a great point by @KaneJMiddleton

I might be missing something, but can anyone explain to me how the variable on the x axis is acceleration? @drivelinekyle @DrivelineBB

In light of the WNBA season and a soon-to-be-published interview, I dived into the topics female basketball players dunking, especially what it takes for that to become more common. Please subscribe to my substack if you are interested! Substack link down below⬇️

@ns19910626 @t_fujimori_ Amazing

New publication. Second first-author paper for @t_fujimori_ , and this is the firstly conducted study for my lab! researchgate.net/publication/39…

Hello everyone! Now that I am near graduation for my PhD, I am still looking for any sports biomechanics-related roles (with experience working with MLB and NBA data and obviously in academia). I would appreciate any referrals/sharing/comments! 😊 #phd #biomechanics

@RealRobReinhart @NBA He started the clip with live dribble, gathered when both feet’s already on the ground and no moving, then shot it

@NBA Obvious travel + possible push off

Thrilled to say I passed my defense with no corrections required and I am officially PhDunked.

Also still open for different job opportunities! Please connect with me!

@ThornesThrows @DrivelineBB I experienced something like this with my hand velo comparisons too. What should be mechanically relevant turns out to be just a meh correlation. That makes me think about the impulse-momentum of the hand ball complex…the change in momentum of the ball before and after BR…

@SamLikesBiomech @DrivelineBB With this interesting gap in data from 6.37 to 14.15 m/s, I wonder if there was a possible error. If I take all low values and add a 1 (ie: 2.69 to 12.69), there is a much more natural graph and stronger relationship. Still not enough to predict ball velo from wrist speeds

Before interning @DrivelineBB this summer, I looked into their OpenBiomechanics Project. Using the raw data, I made visuals showing everything I found with easy to understand visuals Thread of my analysis🧵⬇️

@ThornesThrows @DrivelineBB Okay yeah, something’s up with the lect cluster

@SamLikesBiomech @DrivelineBB I also anticipated those to be very closely related, but here is a scatter plot of all max wrist vs ball velocity and a strange gap There are some other factors such as grip and timing. ie: breaking/off speed pitches. Also late arm where wrist “catches up” with little force

@BleacherReport This is a great graphic

@BNitenson @HoopMixOnly @SportsCentralO Yeah my thought exactly

@HoopMixOnly @SportsCentralO Look like Luka with that step back…. #Luka

you're an expert level nba fan if you can tell who this is
