This conversation is a masterclass on the science of caffeine and how to use it to enhance athletic performance. My guest today is Dr. Lawrence Spriet, one of Canada’s leading exercise physiologists. He’s a professor and chair of the Department of Human Health and Nutritional Sciences at the University of Guelph, and his research has shaped much of what we know today about skeletal muscle metabolism, fuel utilization, and the ergogenic effects of caffeine and other performance-enhancing compounds. He’s chair of the Canadian Gatorade Sports Science Institute, where he’s been deeply involved in applied field research. And, in true scientist-athlete fashion, he’s a committed caffeine user and avid hockey player himself.

• Sweat testing elite hockey players
