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

Cool, will use in next Physiology class - perfect timing!
Check out this free e-book which serves as the essential reading for our "Thermal Physiology in Health and Disease" event this Summer! This e-book draws from the latest research in @expphysiol.bsky.social and @jphysiol.bsky.social 💥

Haha, now we know - but had my feelings on this one earlier;)
David J. Marcinek & Luigi Ferrucci present this #CrossTalk article arguing that reduced oxidative capacity of skeletal muscle #mitochondria is a fundamental consequence of adult ageing🗣️

Was ist die maximale Sauerstoffaufnahme – & wie lässt sich die #VO2max steigern?
In @zeitonline.bsky.social beleuchten wir warum #VO2max ein Schlüssel zur Leistungsfähigkeit & Gesundheit ist und sprechen über 🫁, ❤️, 💪 , effektive Trainingsmethoden & praktische Tipps. Allℹ️👇

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.
🏔️ 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:
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.

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