What does it really take to build world-class endurance—and why do the best athletes train differently than most people think?
At this year’s 4HAS Conference, we’re bringing one of the most influential minds in endurance science to Poreč: prof. Stephen Seiler.
Expert in exercise physiology and endurance performance
Prof. Seiler is a Professor at the University of Agder and one of the most influential scientists in the field of endurance training and performance.
His work has shaped how coaches, athletes, and researchers understand training, with expertise in:
✅ Endurance training and intensity distribution
✅ Cardiovascular and physiological adaptations to training
✅ Brain–body interaction and perception of effort
✅ Performance development in elite sport
✅ Translating elite sport science into practical application
From lab to podium: Science behind world-class performance
Prof. Seiler is globally recognized for his research on how elite endurance athletes train, particularly his groundbreaking work on training intensity distribution and performance optimization.
Beyond academia, he works closely with elite sport systems as a consultant to organizations such as the Norwegian Olympic Federation and professional teams like Uno-X Pro Cycling Team, bridging the gap between science and real-world performance.
His research continues to influence Olympic-level training methodologies and coaching practices worldwide.
Scientific impact and global recognition
With a PhD from the University of Texas at Austin and decades of international experience, Prof. Seiler has published extensively in leading journals and contributed to the evolution of modern endurance training.
He is a Fellow of the American College of Sports Medicine and a former executive board member of the European College of Sport Science, reflecting his global influence in sport science.
Why You Shouldn’t Miss This Keynote
This is not a talk about pushing harder—it’s about training smarter.
Prof. Seiler will challenge popular training myths and reveal what decades of research and work with elite athletes have taught him about performance, consistency, and long-term development.
Expect practical insights, surprising conclusions, and a fresh perspective on what actually drives success in sport.
4HAS Conference: May 28–30, 2026
Poreč, Croatia
If you care about performance—whether as an athlete, coach, or researcher—this keynote will change the way you think about training.
