Following the study in Ghanaian students, this study looks into factors affecting vaccination hesitancy in Ukrainian students 💉🦠
This was a great learning opportunity and I can see how my contribution to the paper (doing the statistics) has improved compared to the first study

Cycling kit with an integrated full-body NIRS system at the Tour de France? 🚴♂️
We surely are far away from the vision presented in a review I was reading today.
But I have to admit, such a technology would be highly intriguing, especially with the integrated display to oxygenation status 🤓

My first time at the #ECSS2025
I'm taking home many positive impressions - I've never seen this many sport scientists in one place!
I enjoyed having Stephen Seiler as chair during my oral presentation. Finally I got to tell him what my thesis is all about 🤓

Our new durability paper is out in SJMSS!
We tested how endurance performance determinants change after heavy-intensity running (90 and 120 min) in well-trained marathoners.
📌Below details of what we’ve found.

Broadly speaking, I agree with @thuyvytnguyen.bsky.social’s basic points. Good preregs take time and effort, analyses plans are very important, and clear hypotheses guide the analysis plan.
Last 2 days I could have analysed some "preliminary" data from 27 lab sessions we've run so far, but I practiced some self-control: I sat down and wrote my preregistration first (then reward myself with a chocolate egg).
My take is that a thoughtful prereg takes time, and requires some thinking...

Only recently I complained about the use of tests for differences with NIRS data compared to other methods.
I am pleased to see that testing for equivalence was used in this study, confirming that BPs and LTs are not the same ⬇️

In our recent meta-analysis with trained athletes, did the athletes who improved their VO2max more also improve their endurance performance more?🤔
No! 😮
In this dataset, +1% improvement in VO2max was associated with a negligible +0.04% change in TT performance. But why? 1/15🧵

Random Sunday thought:
The Joyner Model is typically used to predict performance for a specific distance/time.
Has anyone tried to predict the power/speed duration curve using the model?

Another study found no mean differences between local and systemic breakpoints, but observed large individual differences.
As this is reported again and again, maybe it is time to actually test for equivalence instead for differences? 🤔

The joy of working with athletes and the importance of consistent work
When working with developing athletes, it's all about doing decent work and not doing more than needed. Even a 6-week forced break following an injury shouldn't matter in the long run.
Currently MMSS ~ 5W/kg with room to grow 📈

You will note how the drug schedules look suspiciously like the “periodization” (wink-wink-nudge-nudge) schedules found in many training manuals / books.
