S2 EPISODE 36 - Fueling Endurance Athletes & Periodizing Body Composition w/ Dr. Trent Stellingwerff PhD

Dr. Bubbs interviews renowned physiologist Dr. Trent Stellingwerff PhD to discuss Eliud Kipchoge's record-breaking performance at the Berlin Marathon and the fueling strategies of elite marathoners. He also talks about the role of glycogen availability as a training regulator and the purposeful application of low carb availability training sessions in elite performers. As well, Trent dives into his past research into body composition periodization in endurance athletes and how it can impact athletic performance, injury risk and illness over a career. He shares insights into daily caloric restriction and weekly bodyweight loss targets as well as factors to consider before implementing this strategy with athletes. Finally, Trent shares his tips for recreational runners on improving performance and health and avoiding the trap of trying to ‘fuel like the pros’. Fantastic insights from a world-leader!
