Very demanding to organize those field projects, but very satisfying - both for the science and the human relationships. So many memories...

[Lars Nybo @Nyborger_Nybo]

@physoc 10 years later funny story, but suffered a lot during the desert part - good studies though with @DrJPeriard and @ephysiol

Le @creps_montp a ouvert 2 formations sur le stress environnemental :

💻Formation courte en visio

Thank you for highlighting this issue. Note:
🧠EHS does not necessarily involve collapse (CNS dysfunction can be disorientation, confusion...)
💦EHS patients are still sweating (dry skin is classical HS, not EHS)

🚑 You’re the Doctor:
A 25-year-old marathon runner collapses at the finish line. Bystanders say he was confused and agitated before collapsing. On arrival:
•BP: 88/60 mmHg
•HR: 145 bpm
•Temp: 41°C (105.8°F)
•RR: 30/min
•Skin: Hot, dry, no sweating.

What’s your next step? 🩺

A. IV fluids and antipyretics 🌡️
B. Rapid sequence intubation 🛏️
C. Ice-water immersion 🧊
D. Administer adrenaline 💉
E. CT brain to rule out stroke 🧠

👇 Comment your answer & reasoning!

[Nick Tiller, Ph.D. @NBTiller]

Why are we still ice bathing?
Robust evidence shows cold-water immersion after training INHIBITS recovery by blunting muscle protein synthesis and anabolic signaling.

Why, then, are we still doing it? It's culturally ingrained at this point. Athletes are jumping in cold tubs because that's what we do, and fitness influencers have more sway than credible scientific experts.

Only in unique circumstances, e.g., between successive competitive heats, is there any potential benefit.

Great figure by @ValentinDab summarizing current (limited) knowledge. Human studies on the way

[Sebastien Racinais @ephysiol]

Free in today issue of @BJSM_BMJ (September): This is just an editorial, but already attracted some attention

Stay tuned for upcoming original research by @ValentinDab @Mery_MT_ and others with data challenging ice usage in for musculoskeletal injury

C’est en effet un lieu magnifique. La vue de cette tribune est exceptionnelle
Incredible view from the #BeachVolleyball venue @Paris2024

Heat stress and hydration tips displayed on the main giant screen @rolandgarros site. Kudos to @Paris2024

[Sebastien Racinais @ephysiol]

It has been a while but I’m back to Twitter to give some insight on @Paris2024
Letting my @creps_montp uniform aside for 4 weeks but the new #IOC uniforms look good and confortable 😁
