#Durability ≠ #Fatigability ≠ #Repeatability ≠ #Resilience.
Our JAP Viewpoint (accepted!) dives into why these distinct concepts matter in endurance research.
Grateful for the collab with Michael J Joyner + @billysperlich.bsky.social.
Let’s discuss at #ECSS2025 or during the Tour de France!

Zone2 training may not deliver the same benefits for everyone. Our new study found substantial interindividual variability in physiological responses, even among trained cyclists, indicating that personalized intensity prescriptions are necessary. @billysperlich.bsky.social

Our recent study included the effects of creatine supplementation on vlamax-testing. The results imply that some athletes may be limited by their metabolism while others could be limited by the testing setup. Read more about it here:

Supplementation of Creatine Monohydrate improves sprint performance but has no effect on glycolytic contribution: A Non-Randomized, Placebo-Controlled Crossover Trial in Trained Cyclists

Summary: Creatine loading supplementation increases 15s-work while hinting at different mechanisms involved in its effects on individual limitations to 15s-work.

The world doesn't immediately fall apart at the 1.5 °C limit, but experts say we are "reaching the end of what we thought was a safe zone for humanity".

Earth breaches 1.5 °C climate limit for the first time: what does it mean?

The threshold has been exceeded for only one year so far, but humanity is nearing the end of what many thought was a ‘safe zone’ as climate change worsens.

VO₂max : So drehen Sie an der magischen Zahl des Sports

Kein Wert korreliert so stark mit der Lebenserwartung wie der VO₂max-Wert. Das Gute: Man kann ihn steigern und sein Sterberisiko senken. Und das ist gar nicht so schwer.

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.

Billy Sperlich @billysperlich.bsky.social · Feb 15

🏔️ 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.

🚀 Skyrocketing Costs: What once cost <€1,000 to convert a Word file into a PDF with a DOI now easily surpasses €4,000. The process itself hasn’t changed - it’s still just flipping a Word file into a PDF- yet the publishing industry has turned it into an expensive mega-market.

👉 10–15 years ago, I was a strong proponent of open access publishing. My reasoning was straightforward: practioners outside of academia should not have essential knowledge locked behind paywalls.

However, my perspective has shifted due to two main factors:
