@pjvazel @MTalivee Thanks PJ. One thing to clarify is that last year we measured the wind in the direction of the circle (as a projected headwind) whereas this year we measured in actual wind direction, which was a right quarter wind.

@MTalivee The only reliable wind indication is the one measured with an anemometer by @MUSportScience, as announced during the live on YouTube.

#throwtown Best discus competition ever : All best-marks for place 1 to 7 beaten 5 throwers over 70m, previous best was 2!!! Alekna 2 valid throws 74.89 and 75.56, 2 WRs (and a 74.00 counted as foul). Wind was measured at +5.1m/s for the 74.89 Denny also over the previous WR

🚨 Online Symposium 8th April 🚨 Free for members, with workshops and presentations focused on upskilling within biomechanics. ✅ open-source markerless algorithms ✅ Functional Data Analysis (FDA) ✅ applied biomechanics in elite sport ✅ annual conference details + Q&A

End-of-semester means some "free" time to tinker with #biomechanics projects, like this "bullet time" animation of a discus throw 😀 Happy holidays, everyone.

Our lab is off to Tucson, AZ to collect data at the 2024 North American Open Finals. Come find us if you want to geek out about #biomechanics of #weightlifting, like this amazing 200kg jerk by 81kg lifter Dae Hee Kwon from South Korea at this year's World Jr Championships.

@theiamarkerless Through a regression approach that combines body position and “hammer drag” values from the literature to *estimate* the hammer location. We just want to be ready for when you guys add object tracking 😊 Happy American Thanksgiving.

@MUSportScience How are you tracking the hammer?

Upgraded our hammer throw #biomechanics analysis. Added a ball force vector to better understand patterns of force application. The increase in the tangential force during double support is pretty cool to see. Also include single/double support phases and high/low points.

@NickJWillsmer Yup, I’ve read most of his articles. Still the only(?) work to get GRF data on the hammer throw, which is super cool. That said, I do want to look at the synchronicity you describe in more detail because Koji’s work only included three throwers.

@MUSportScience awesome 🙏 have you seen the work of koji murofushis PhD in sports biomechanics looking at hammer throwing? IME there also seemed to be a greater synchronicity between the high and low point of hammer compared to CoM with longer throwers, what distance was used for the model?👍🙏

@Coachmdd Thanks for the kind words. And yes, I’m continually humbled by coaches who can “see” this information live. Hopefully this can still help by validating hunches etc and quantifying what they see. Happy thanksgiving to you as well.

@MUSportScience 2D analysis confirms via data points what good coaches already see, quantifying “too fast/slow/high/low” Really really appreciate folks like you who raise the bar as you do. Happy Thanksgiving

@EACoachDavis Hi Matthew, we use @theiamarkerless to get the 3D position of joint centers etc. The biomechanical modeling is done with Visual3D and MATLAB. Feel free to DM me if you have specific follow up questions. Cheers.

@MUSportScience This is really awesome. I'm looking into doing a master's in something like this in the next few years. Are these created with pose estimation?

One of the most impressive lifts from the 2024 IWF Jr WC's in Leon, Spain. This was Guan Ling Chen's 98kg snatch from the 55kg A session. Totally amazing. @DaneChamps and I talk a bit more in depth about weightlifting in this podcast, recorded in Leon! youtube.com/watch?v=njdE_o…

@MUSportScience Could you please give link to the conference?

Putting the final touches on my presentations for the European Shot Put Conference this weekend in Tallinn, 🇪🇪. And yes, one of them will focus on the discus😀

@rotationalperf I’ve been mulling that over, too, after you brought that up last time. It’s so interesting because we use @theiamarkerless for tracking and the ensemble average does fall in the range you mentioned. I hope to ask Mantas Jusis about it this weekend. So stay tuned.

@MUSportScience Great infographic. how do you explain 90 deg of separation when 45-50 deg is likely the reported physiological limit for axial rotation?

I recently had the opportunity to travel with @USWeightlifting to Leon, Spain, for the @iwfnet Jr World Champs to conduct in-comp biomechanical analyses. It was an amazing experience. Thanks to so many people, but especially @MarcosASoriano1 for your help and hospitality.

Congratulations @NayunAhn_Ahnna on the first publication from your dissertation! Really cool study on muscular effort during the sit-to-stand task in young and old adults. sciencedirect.com/science/articl… @MUMike24 @ProfCaraLewis

@AmitBatra4 We use a combination of @theiamarkerless, Visual3D, and @MATLAB for the analysis.

@MUSportScience What method do you use to obtain such analysis?

It's hammer #biomechanics time! The tracking is not quite there yet, and it took us longer than expected to get to this point, but thanks to our amazing grad student Emma Patterson for her perseverance. We're super excited. Happy Friday!

First "to-do" upon returning to the office after summer break and watching Rojé Stona throw 70m in the men's discus final in the Olympics was to go back and analyze his 69m throw at Throw Town Ramona earlier this year.
