Interesting review on the current High Carb trend in endurance athletes. We just covered the debate between Dr Burke and Dr Noakes. This review adds some interesting insights.

Fuelled or Fooled? Examining the Evidence and Mechanisms Behind Ultra-High Carbohydrate Intake in Endurance Athletes
link.springer.com/article/10…
@theplews1 & team describe lack of.evidence for many of the claims for ultra high carb intake... but also explore how they may be working beyond our current evidence base
Fuelled or Fooled?
Our latest Sports Medicine paper examines the evidence for ultra-high carbohydrate intake in endurance sport.
Bottom line: promising in theory, but current evidence is insufficient to support broad recommendations for most athletes.

It's finally here! You can now pre-order our HRV book on Amazon. It'sbeen a long time coming, and very thankful for the work we've done with my amazing co-authors. Marco Altini, Sylvain Laborde and Emma Mosley.

I trained Hyrox endurance with Ironman record holder Dan Plews this weekend. @theplews1
At this point I consider myself a fairly good endurance athlete, but nowhere near the level of Dan.
Our physiological response to the session was radically different.
Dan's heart rate remained fairly consistent across the strength and endurance work, whereas I had extreme heart rate spikes on each of the pure strength components.
This explains why Dan is able to run close to his threshold running pace during Hyrox, but I can’t even sustain my marathon pace 👇
Can carbs during exercise spare muscle glycogen?
Yes,but barely. Our new meta-analysis (31 studies) shows CHO intake = a small reduction in muscle glycogen use (~20–25 mmol·kg⁻¹ over ~110 min).
No effect of: carb dose, timing, type, exercise mode, starting glycogen.

“I’m not saying things like triathlon are bad for you, but you can’t hold that much muscle mass… with Hyrox that isn’t something we need to be as concerned about”
Dr. Dan Plews explains why he's taken up the sport of Hyrox. @theplews1

🏋️♂️ STRENGTH ⚡ ENDURANCE 🏃♂️—FINDING THE BALANCE!
Training for HYROX and hybrid sports? Dr Dan Plews @theplews1 wants you to understand that you CAN become TOO STRONG or TOO ENDURANCE-FOCUSED. The key? OPTIMIZING your training mix 🔥!

Is it obligatory to ingest >90g carbohydrate/hr if one wants to run a sub-2hr marathon? This theory is based on 2 key presumptions. First that the oxidation of fat provides essentially no energy for elite athletes running at 21.2km/hr. Second that the rate of exogenous carbohydrate oxidation by the muscles during 2 hours of exercise exactly equals the rate of carbohydrate ingestion.
@PhilipPrins11 and I evaluate these assumptions and conclude that the 2hr marathon will only be run by athletes able to extract at least some energy from fat oxidation when running at such a high intensity for 2 hours.

The End of Carbs: Dr. Koutnik Reveals BRAND NEW Study that Ends 57-Year Debate on Performance

🧵Very-low carb (ketogenic; LCHF) vs high-carb diet (HCLF):
-Ironman triathletes (n=10)🚴♂️
-"Hitting the Wall"🥵
-Homeostasis monitoring ("Keto-Adaptation")📈
Our hypothesis was wrong...again
🔍CRITICAL QUESTIONS:
1) Does adopting an LCHF diet impair strenuous time-to-exhaustion performance?
2) Does carb supplementation (3.4g/20min) during exercise, 6-12x lower than current CHO fuelling recommendations, improve time-to-exhaustion on LCHF? If so, how?
3) Keto-adaptation homeostasis timeline?
🔏KEY CONTROLS:
1) Randomized & Controlled
2) ❎Crossover Design
3) ↔️Calories
4) ↔️Physical Activity Load
5) Dietary Compliance:⬆️BHB + CGM
What did we see? 1/n

You will be convinced when the top 0.00000025% of the population does it? Where genetics and training are the primary drivers of success?
What about crossover controlled RCTs which shows it repeatedly in high level athletes?
What about the other 99.999999%

We are thrilled to see this one published just in time for Christmas!
Carbohydrate ingestion during prolonged exercise blunts the reduction in power output at the moderate-to-heavy intensity transition

Taking inspiration from Prof. @ProfBuehlerMIT 🙏 we had a blast building a #knowledgegraph from an #HRV research paper, followed by a RAG system that can answer questions about it!
