Lactate Reimagined: From Fuel to Signal With Dr Aitor Viribay Morales and Prof Paul Laursen

For decades, lactate was viewed as a waste product associated with fatigue and declining performance. Today, a growing body of research paints a very different picture.In this episode, sports scientist and researcher Aitor Viribay Morales explores the evolving science of lactate, from its role as a critical fuel source to its emerging importance as a signaling molecule that influences performance, recovery, and adaptation.The conversation dives into the lactate shuttle theory, the relationship between lactate and endurance performance, the interaction between lactate and the nervous system, and the growing interest in exogenous lactate as a potential tool for athletes. Aitor also shares insights from his work in exercise metabolism and sports nutrition, highlighting how our understanding of lactate continues to evolve beyond traditional models of fatigue.Whether you're a coach, athlete, researcher, or endurance enthusiast, this episode offers a fascinating look at one of the most misunderstood molecules in sports science.Interested in learning more about the latest developments in endurance performance and sports science?
