Just like in sports: When all options have been explored, it’s time for a change. That’s exactly how I feel about X. Hoping that #BlueSky brings fresh momentum and a space for meaningful exchange, you can now find me there.

Time to move on: We are ending our activities on X. Stay connected with us through our other channels.

Zeit, neue Wege zu gehen: Wir beenden unsere Aktivitäten auf X. Bleiben Sie mit uns im Dialog – auf unseren anderen Kanälen.

I still advocate open-access publishing. But we urgently need better regulation. Right now, the major beneficiaries are large publishers. In Germany alone, we are spending millions of taxpayer euros merely to “flip a Word file into a PDF” - and that’s not sustainable.

Call to Action: Let’s control the open-access publishing madness! Read why 👇

🏔️ Information Overload: As the study below illustrates, the sheer volume of publications has grown so large that even specialists or expert practitioners struggle to keep up. My original goal - making knowledge more accessible -has, in some ways, backfired.

Carbon monoxide inhalation for endurance gains? Minor benefits, but huge risks—hypoxia, organ damage, even death—and unknown long-term effects.
A global team urges a ban to safeguard athletes & fairness. @NADADeutschland @wada #antidoping @DOSB

[Øyvind Skattebo @Skattebo_Oyvind]

Repeated carbon monoxide inhalation triggers hypoxia-induced erythropoiesis, increasing hemoglobin mass—a practice likely abused by endurance athletes. We call on WADA to act urgently and ban this dangerous doping method. Our editorial by @BillySperlich:

@jonisportsci @JPhysiol Sure! Send me a mail!

🆕In @JPhysiol we challenge strict standardization in exercise physiology and promote a flexible, blended approach. Combining classical methods with modern tech like #AI and #wearables improves threshold assessments while balancing accuracy & practicality. https://t.co/Ty10h7HtZv

@jem_arnold @ChZinner Hopefully soon… review is ongoing…. :)

[Billy Sperlich @BillySperlich]

@jem_arnold @ChZinner In our experience, time trial performance is the most sensitive indicator when tracking changes in performance/physiology over time. All other variables can be quite "shaky".

Do it!!! I really have great memories of the congress…

[H-C Holmberg @HCHolmberg1]

International Congress on Science and Skiing in Val di Fiemme 🇮🇹

Great Congress - Great Speakers - Great Opportunities for Skiing - Great Food and 🍷

Mark your calendars for the 10th International Congress on Science and Skiing, coming to the beautiful Val di Fiemme, Italy in January-February 2025! #ICSS2025 @ICSS2025 #dolomites #skiing @fisalpine @FISCrossCountry #ski #snow #gastronomy

Honestly, this is getting crazy.
#OpenAccess expands knowledge sharing, but the rising publication fees pose a significant barrier for many researchers, especially those without institutional funding. We must find a balance between access and affordability....

[Billy Sperlich @BillySperlich]

@WilleValkeaoja @HCHolmberg1 @PeterDuking @BorjaMunizP @DrMJoyner @japplphysiol Exactly! All athletes should have access; otherwise, it could be viewed as "technodoping"...

[Billy Sperlich @BillySperlich]

@PeterDuking and I jumped into the intriguing debate about "Technological advances in elite sport: If we draw a line, where would we stop?" sparked by @BorjaMunizP, Yannis Pitsiladis & @DrMJoyner in @japplphysiol

Where would you stop?

@WilleValkeaoja @HCHolmberg1 @PeterDuking @BorjaMunizP @DrMJoyner @japplphysiol Both "supertechnological" & "supernatural" extremes represent outer edges of what is possible in sport. In my POV, innovations like supershoes or pacing assistance are within the bounds of acceptable athletic competition as long as all athletes have equal access to such tech.

3/3 We suggest implementing additional running sessions and modifying small-sided games to better balance workloads and improve non-starters' physical preparedness.

1/3 🆕 study in @PLOS
We aimed to compare the weekly training and match loads between starting and non-starting professional #soccer players and to identify variations across training modalities.

2/3 Our data showed that non-starters consistently experienced lower workloads, particularly in high-intensity activities during matches and compensation training. #football
