This study shows that a ketogenic diet decreased myocardial fatty acid uptake oxidation.
I have always tried to educate athletes on the concept that ketogenic diet and ketones are the poorest of all fuels for humans. In a way, from an evolutionary perspective, it’s the last resource and the “survival” diet when nothing else is available…
In my humble opinion it is important for athletes to be educated and acquire concepts so they can learn about diets that can jeopardize their performance.

WE DID IT! 🚨 You heard that right. We met our match goal for the #MudFund, raising a total of $50,000 for the 2025-26 Cyclocross season! 🎉 A HUGE thank you to our new and returning donors, our amazing athletes, and our dedicated staff. This wouldn’t be possible without you!
On aerobic glycolysis vs anaerobic glycolysis.
This terminology has existed since the beginning of times and ingrained in every physiology, biochemistry and medical textbook.
According to this terminology, aerobic glycolysis is the oxidation of glucose to pyruvate in cytosol then to Acetyl-CoA in mitochondria in the presence of oxygen. Anaerobic glycolysis is the reduction of pyruvate to lactate under “anaerobic conditions”.
However this terminology is wrong as lactate is the real end-product of “both” glycolysis. Over the last 50 years Dr. George Brooks has worked on this and proven it.
The ratio of lactate to pyruvate at rest is ~30-40 and at high intensity exercise is up to 500.
So, even during resting conditions, the production of lactate is significantly higher than the production of cytosolic pyruvate…Hence, glycolysis should be just that, glycolysis…
This wrong terminology has penetrated into so many fields in medicine and biology as well as exercise physiology and training leading to terms like “aerobic threshold” and “anaerobic threshold”. Simply, they don’t exist as they are portrayed, since both metabolic events are under fully aerobic conditions and also lactate is the main end-product over cytosolic pyruvate.
The pure anaerobic threshold is the change from glycolysis to ATP-PC system during sprinting where anaerobic conditions are the predominant.
In a world with so many training zones and philosophies, at least we should agree in the “modern” principles of muscle bioenergetics during exercise.
We should make an effort to move on and get rid of 50+ year old inaccurate concepts like “anaerobic threshold” and “aerobic threshold” 🙏

Roads aren't any more dangerous when cyclists are allowed to treat stop signs as yield. So why aren't there more laws allowing the 'Idaho stop'?https://t.co/jLEshiVMKf
Fatigue resistance and durability are trainable, but they don't automatically improve with improved aerobic conditioning!

New study assessed sleep quality in 1,600 U.S. Olympians. ~40% were classified as "poor sleepers."
Takeaways:
(1) there are a bunch of reasons hard training can interfere with sleep;
(2) if your sleep isn't perfect, you can still make the Olympics.
