Carbohydrate intake in racing - a case for going very high with Aitor Viribay Morales (Astana Pro Team) | EP#269

Aitor Viribay Morales is a performance nutritionist at Astana Proteam (a World Tour cycling team) with a background in science and academia. In this interview we discuss his research findings and practical experience with ingesting really high amounts of carbohydrate (up to 120 g/h) in races, and the effects such high-carb strategies can have.  

 

IN THIS EPISODE YOU'LL LEARN ABOUT:

-Aitor's studies in mountain marathon runners on high-carbohydrate (up to 120 g/h) intake during racing and its effects

-Performance effects, recovery effects, and muscle damage effects of high-carbohydrate intake in races

-Is there not an absorption rate limit of 90 g/h as we have been told? 

-How to train the gut to absorb 120 g/h of carbohydrate

-How do the potential benefits of high-carbohydrate intake in racing relate to training? 

-Metabolic flexibility, and the height and width of the fat oxidation curve

-Practical takeaways
