What still limits a sub-2 marathon? And could a second fuel move it?
I wrote a technical analysis on running economy, durability and exogenous lactate. It has more questions than answers, on purpose. 🧵

The usual suspects are arguing about CHO intake for endurance performance. Meanwhile, many elite triathletes will target 150+ g/hour at tomorrow's Ironman World Championship. Many of our athletes will be in the 120+ g/h range; why? Because we've seen the results it provides...

Check this one on CHO and durability!!
Even if it’s hard to understand, one of the few papers demonstrating effects of CHO on durability.
Well done - this research group is fantastic btw. Make you you follow them!
New research from our group: 100 vs. 60 g CHO·h⁻¹ during prolonged cycling improved performance durability in trained male endurance athletes.

Lactate is a buffer agent, but not only on pH.
👉🏼 Lactate buffers CARBOHYDRATES in the body.
🛩️🆙 Lactate elevates up the travelling status of carbons: from traveling in Economy (glucose) to a privilege seat in Business (Lactate) 😜
Read this paper 👇🏼

Latest on Exolactate website. An important exercise to do and a relevant consumer-level information to consider.

Latest on Exolactate website.
Direct human evidence that lactate itself — not the accompanying sodium, which was matched in the control arm — suppresses fat mobilization via GPR81, consistent with a glucose- and glycogen-sparing signalling role.

Thank you!
(Time to develop open science and talk about it - Exciting times).

Muchas gracias por la entrevista!! Hablamos un poco más a fondo sobre el desarrollo de Lactato Exógeno a través de @fromlabtofield.

The final pathway of Carbohydrate Oxidation can be called Mitochondrial Lactate Oxidation complex (mLOC).
I really enjoyed re-reading this paper by @RGLEIJA007 et al. One you shouldn't miss!

The energy resistance principle by @MitoPsychoBio .
One of the most - if not the most - inspiring concepts I have ever read. This is helping me understanding everything we have done with Energy Transformation measurement in professional/elite athletes.

High-intensity adaptations without the fatigue? 🧪
Zone 4 volume has a strict ceiling. What if exogenous lactate could mimic those cellular signals without the training load?
@PaulBLaursen & @MVAitor explore:

Hablando sobre el nuevo complemento que podría revolucionar las ciencias del deporte, el consumo de Lactato oral teniendo múltiples beneficios💪, hay que ir con calma pero esto promete mucho para la nutrición deportiva🚵♀️⚽️

Es largo y hay cosas que se me escapan porque no soy especialista en la materia pero esto es muy interesante, por si quieres echarle un ojo

🔴 Lactato, el combustible invisible del Tour de Francia
Ayer comenzó la ronda gala en Barcelona. Además de los ciclistas, hay otro protagonista inesperado: el lactato.
Este metabolito ha ganado una enorme relevancia en ámbitos muy diversos, desde el cáncer hasta el rendimiento deportivo. De hecho, la forma en que el organismo lo produce y utiliza, tanto en reposo como durante el ejercicio, puede ser un buen indicador del estado metabólico de un paciente o del nivel de entrenamiento de un deportista.
Ahora sabemos que, lejos de ser un producto de desecho, el lactato es una importante fuente de energía, especialmente durante el ejercicio.
✍️ En este artículo, José Antonio Benítez Muñoz, doctor en Ciencias de la Actividad Física y del Deporte e investigador en el Laboratorio de Fisiología del Esfuerzo (INEF Madrid), analiza desde la base qué es el lactato, cómo medirlo y cómo utilizarlo para evaluar el estado de entrenamiento.
Si eres deportista o entrenador, te recomendamos su lectura.

Massive thank you to Aitor Viribay (@MVAitor) for speaking with me for VELO about a potentially transformational fueling solution being used at the Tour de France.
ExoLactate - remember the name.

Tour de France riders are using a secretive new fueling solution that could blow endurance racing apart.
Velo got all the details of a world-first lactate energy gel could be as transformative as high-carb fueling or running supershoes:

Muscle glycogen, much more than an energy reservoir.
Intramyofibrillar glycogen can be related to muscle function by regulating excitation-contraction coupling.
I find it fascinating!!
