In this Subject Spotlight, we dive deep into the science and evolution of endurance fueling with Ray Spradlin, exploring how nutrition has transformed how athletes approach long-distance events. From the early days of dangerous concoctions like egg whites, brandy, and strychnine, to the groundbreaking innovations of sports drinks and dual-carb products, we’ll cover it all. Across four episodes, Ray examines the development of the science behind fuelling strategies - understanding the importance of research and development. Ray considers how fuelling strategies have become a critical aspect of performance, with modern athletes using cutting-edge technologies like continuous glucose monitoring to optimise their nutrition during races. Learning from examples of elite endurance athletes who have redefined fueling with precision-based, data-driven strategies that allow them to push their physical limits, Ray will support you in considering how sports science can provide an edge for overcoming any wall.

Meet the academic
Ray Spradlin
Dr. Ray A. Spradlin, Ph.D., is an Assistant Professor at Johnson & Wales University in the Exercise and Sports Science program and the College of Health and Wellness. Originally from South Florida, Dr. Spradlin moved to Gainesville, FL, to pursue both his undergraduate and doctoral studies at the University of Florida. While attending UF, he studied how endurance exercise affects mitochondrial bioenergetics of prostate tumors and the role insulin-like growth factor 1 (IGF-1) plays in muscle disuse atrophy, function, metabolism, and exercise adaptations. In 2020, Dr. Spradlin left Florida to work for the University of Illinois, Urbana-Champaign, studying extracellular vesicles (EVs) and assisting in developing a novel approach to confer exercise benefits and combat muscle wasting utilizing EVs. Since joining JWU in Fall 2023, Ray has been excited to teach students about exercise science and its important role in a healthy and fulfilling life. He is currently working with other faculty and collaborators pursuing research interests related to human performance.
