About

Lawrence L. Spriet is a leading exercise physiologist whose research has fundamentally shaped our understanding of muscle metabolism, substrate utilization, and performance in both health and sport. His key contributions center on how skeletal muscle regulates carbohydrate and fat metabolism during exercise, with seminal work on glycogenolysis, lactate metabolism, and the role of caffeine as an ergogenic aid. Spriet’s studies have been instrumental in revealing how high-intensity training and dietary interventions alter muscle enzyme activity and fuel selection, directly informing athletic training and nutritional strategies. With over 30,000 citations, his impact is immense, and his papers on caffeine’s effects on endurance performance and muscle glycogen sparing remain foundational. More recently, he has advanced sport science technology, co-authoring a 2022 study validating the Kinexon local positioning system for measuring external load in ice hockey players—demonstrating his ongoing commitment to bridging lab-based physiology with real-world athletic monitoring. A professor at the University of Guelph, Spriet has also mentored generations of researchers and served as a key figure in organizations like the American College of Sports Medicine, cementing his legacy as a pioneer in exercise metabolism and applied sport physiology.
