Abstract in brief

  • A study examined the effects of a low-carbohydrate high-fat ketogenic diet (LCKD) over 12 weeks on well-trained male endurance athletes compared to a high-carbohydrate (HC) diet.
  • The LCKD group lost significantly more body mass and body fat and had elevated levels of fasting serum beta-hydroxybutyrate, suggesting improved fat metabolism.
  • Despite these changes, there was no significant difference in overall performance during a 100km time trial, but the LCKD group showed improvements in sprint peak power and critical power compared to the HC group.

Se encuentran muchas investigaciones que hablan del proceso de cetoadaptación en el trabajo aeróbico, con protocolos keto de 10-12 semanas. Más eficiencia en la movilización y oxidación de los lípidos, lo que aumenta el rendimiento competitivo.
