Callum Brownstein, PhD, is a lecturer in exercise physiology at Newcastle University. Callum has conducted extensive research in fatigability, and the mechanisms of neuromuscular fatigue in (among others) endurance exercise. In this interview, we dive deep into the mechanisms and applications of neuromuscular fatigue in an endurance sports context. 

IN THIS EPISODE YOU'LL LEARN ABOUT:

-What is fatigue? 

-Differentiating between impairments in contractile function ("peripheral fatigue") and voluntary activation ("central fatigue")

-How can fatigue and its underlying mechanisms be measured? 

-Different fatigue mechanisms in cycling vs. running

-Differences in magnitude of fatigue and fatigue mechanisms between the different intensity domains

-The impact of exercise duration on fatigue

-Practical applications for triathletes and endurance athletes
