Asker Jeukendrup

Asker Jeukendrup is a Dutch sports scientist and sports nutritionist known for research on endurance physiology, carbohydrate metabolism, and performance nutrition. He has held academic positions, consulted for elite Tour de France cyclists, Olympic Games teams, and commercial sports brands, and authored textbooks and review articles that influenced practice in cycling, marathon running, and triathlon. His work bridges universities, professional sport organizations such as Union Cycliste Internationale and International Association of Athletics Federations, and industry actors including Gatorade and PowerBar.

Early life and education

Jeukendrup was born in the Netherlands and completed undergraduate studies in biomedical sciences at the Vrije Universiteit Amsterdam followed by postgraduate training at Maastricht University where he studied exercise physiology and metabolism. He earned a doctorate focused on carbohydrate metabolism and endurance performance, engaging with research groups affiliated with institutions such as University of Birmingham and collaborating with investigators from University of Oxford and University of Copenhagen. During training he interacted with researchers linked to organizations like the International Olympic Committee and the European College of Sport Science.

Academic and research career

Jeukendrup held academic appointments at universities including the University of Birmingham where he served in institutes connected to School of Sport and Exercise Sciences and the National Institute for Health Research. His research emphasized substrate utilization, gastrointestinal tolerance during exercise, and carbohydrate periodization, publishing in journals like Journal of Applied Physiology, Medicine & Science in Sports & Exercise, and Nutrition Reviews. He supervised doctoral candidates who later joined faculties at Loughborough University, Auckland University of Technology, and University of Sydney, and collaborated on multidisciplinary projects with centers such as the MRC and the NIHR. His methodologies incorporated metabolic cart systems used in laboratories of Karolinska Institutet and protocols comparable to those from Stanford University exercise science groups.

Sports nutrition consultancy and industry work

Jeukendrup provided consultancy to professional teams in cycling, triathlon, and athletics, advising athletes in events from the Vuelta a España to the Boston Marathon. He consulted for commercial sports nutrition firms including PowerBar, Gatorade, and sports technology companies aligned with Garmin and SRAM, and advised product development informed by trials similar to those conducted at Auburn University and University of Florida. He participated in expert panels for governing bodies such as World Athletics and the UCI on hydration and carbohydrate guidelines, and worked with high-performance programs linked to national federations like British Cycling and USA Triathlon.

Publications and editorial roles

Jeukendrup authored and co-authored textbooks, practical guides, and review articles on sports nutrition, contributing chapters alongside scholars from University of Bath, University of Stirling, and McMaster University. He served on editorial boards for periodicals including International Journal of Sport Nutrition and Exercise Metabolism, Nutrients, and Sports Medicine, and was invited to deliver keynote lectures at meetings like the Gatorade Sports Science Institute symposia, the American College of Sports Medicine annual meeting, and the European College of Sport Science congress. His publications influenced position stands produced by organizations such as British Nutrition Foundation and informed consensus statements issued by IOC working groups.

Awards and honors

Jeukendrup received recognition from professional societies and academic institutions including awards from the American College of Sports Medicine and honors from university departments connected to the Faculty of Medicine at partner institutions. He was invited to honorary lectureships and conferred visiting professorships at centers like Lund University and University of Queensland, and contributed to prize-winning collaborative grants funded by agencies such as the European Research Council and national research councils comparable to the UK Research and Innovation.

Personal life and interests

Outside academia he has been involved in applied endurance sport, engaging with communities around cycling, running, and triathlon clubs, and participates in professional networks that include members from World Triathlon and national training centers. His interests extend to science communication and public outreach through workshops, podcasts, and conferences associated with organizations like TEDx and national science festivals.
