Is Exogenous Lactate the "Holy Grail" of sports fuelling?

For years, we’ve been focused on >120g/h CHO intake. But how can we explore new limits?

Lactate is not a waste. It´s the most efficient and preferential fuel in the human body.

A thread on the next metabolic frontier🧵

@Picalagartos_ Thank you!

Nervous system and glucose /lactate relationship is so exciting!!

@ProfTimNoakes @PaulBLaursen Hi Tim. Please check our humble study from 2020.

Neuromuscular function and RPE are good markers of what happened - impact on nervous system! We didn’t have resources to measure more but that was a sign to where to explore. That’s a good path… Thank you!

Scientists (@borjammt et al) identified a single gut bacterium associated with stronger grip, leg press and bench press in humans - and supplementing it boosted strength in mice. It increased muscle fibre size and shifted fibres toward fast-twitch. Read👇

After Zegama, I needed to understand what my body had been trying to say for weeks.

I wrote about the MRI, an old knee injury, and why I’m trying to see this moment as a new challenge: to recover, adapt, and keep learning from the body.

🎙️🆕 Episode: Lactate & Exogenous Lactate in Human Metabolism!

After years of research, I cover lactate metabolism, how exo. lactate may work, what we've tried with athletes & the gaps left to close.

Honored to build on G.Brooks' work. Thanks @DJ_Lipman!

@andreu_canals @DJ_Lipman Me quiero imaginar que pronto. Gràcies!

[Aitor Viribay @MVAitor]

Quick note: This episode was recorded 3 weeks ago now. I can tell, in the last 3 weeks we have learned so much, so please take this into consideration when listening to the podcast. Mostly if I have made any mistake on it :) Thank you!

[Aitor Viribay @MVAitor]

@KarlEtzel LOL!

@FMtrina Eso que te llevas 🤣

Tilting your bed 6° head-up while you sleep may make your body produce more red blood cells. After 5 weeks, blood volume rose 4.1% - similar to what you'd get from altitude training. No change in those who slept flat. Small study (n=9), but intriguing!!

[Aitor Viribay @MVAitor]

@willkirousis Exactly!! Thanks!

[Aitor Viribay @MVAitor]

@OAndrePa I don’t know. Doesn’t say that in the paper 😊

[Aitor Viribay @MVAitor]

Practical note after some easy calculations:

For a 2m bed, this means adding a couple of 21 cm high block under one side!

Hope you appreciate this! :)

@OAndrePa No. It would require while body inclination.
