Pseudoscience

Dr Nick Tiller is a senior researcher in exercise physiology & respiratory medicine at Harbor-UCLA, and author of The Skeptic’s Guide to Sports Science which was named one of Book Authority’s “Best Sports Science Books of All Time.” For over a decade, Tiller has been scrutinizing the health and fitness industry through the critical lens of scientific skepticism, a subject he explores as a regular guest on podcasts, radio, and television. Tiller is a columnist at Skeptical Inquirer, a columnist at Ultra-Running Magazine, and associate editor at the International Journal of Sports Nutrition and Exercise Metabolism. Nick is also a keen marathon and ultramarathon runner. Web: www.nbtiller.com; Twitter: @NBTiller

Asker Jeukendrup has spent more than thirty years working at the forefront of carbohydrate metabolism research and as an applied practitioner in professional cycling, soccer, Ironman triathlon, marathon, and ultra-running at the highest level. Much of the research underpinning current fuelling guidelines has come directly from his lab and his collaborators. The underlying physiology, however, is not elite-specific. The same evidence base informs fuelling decisions for trained age-group athletes, team-sport players, and recreational endurance athletes. Targets scale with workload and tolerance; the principles do not change.
