Sample size estimation revisited Published in Journal of Sports Sciences (Ahead of Print, 2025)

The journal of Sports and Sciences will now require mandatory sample size estimation and justification www.tandfonline.com/doi/full/10.... This is an excellent step that will improve scientific papers. I expect many other journals will follow.

Important Announcement!

The deadline for abstract submissions to the ISB Congress 2025 has been extended to February 14th, 2025!

Spread the word—and let’s get those abstracts submitted!

Thanks Felipe, good to hear! I guess you have seen it, all source code is openly available

📢 Paper alert! 🚨

Do you use ultrasound imaging to look at muscle architecture changes during movement?

Then UltraTimTrack is for you!

We leveraged the benefits of its predecessors, UltraTrack + TimTrack, to enable automatic, objective, and accurate fascicle tracking:

Some of the big news we report: "...suggesting that upon activation, [I-band] titin stiffness increased ~2.2 to 3.1 times compared to the passive state"

🚀✨ Abstract submission is NOW OPEN for the XXX Congress of the International Society of Biomechanics (ISB2025) in Stockholm! 🇸🇪📚

🏃‍♂️🔍 Are you ready to share your groundbreaking research in biomechanics? 💡 Submit your abstract and be part of the global stage! 🗣️🌐

Here we are, ready to share the latest research in biomechanics! We're excited to connect with our readers, authors, reviewers, and editors here - follow us to stay updated on cutting-edge advancements!

After a long process, I will soon have a paper out at PNAS that explores the molecular mechanisms of residual force enhancement using some cool mouse models and small-angle Xray diffraction. It is not just about titin-based forces, per se, but they run the show 😎. Details OTW #titin #MuscleScience

Latest work from Brent Raiteri out in J Physiol! Residual force depression is NOT accurately predicted by muscle work (as usually assumed) but rather by the number of active muscle fibres during shortening. Funded by @dfg_public. Check out the OA-link:
