Dr. Stephen Seiler

Professor in Sport Science, University of Agder

Dr. Stephen Seiler is an exercise physiologist and one of the world’s leading minds in the science of cycling.

After growing up in the U.S. and earning his doctoral degree from the University of Texas at Austin, Stephen Seiler, Ph.D., FACSM, has lived and worked in Norway for over 20 years as a university teacher, researcher, and leader. He is past Vice-Rector for Research and Innovation and past Dean of the Faculty of Health and Sport Sciences at the University of Agder in Kristiansand, Norway. Currently, Dr. Seiler is Professor in Sport Science at the same institution.

While anchored in an academic environment, Dr. Seiler has also served as research consultant and scientific advisor for a research foundation, sports teams, a regional hospital, and the Norwegian Olympic Federation. From 2014 to 2019, Dr. Seiler served on the Executive Board of the European College of Sport Science, where he founded the Elite Sport Performance Special Interest Group in 2014.

Over the last 15 years, Dr. Seiler has become internationally known for his research publications and lectures related to the organization of endurance training and intensity distribution. This work has included both descriptive and experimental approaches, investigating cyclists, rowers, cross-country skiers, orienteers, and distance runners. His work has influenced and catalyzed international research around training intensity distribution and the “polarized training model.”

Dr. Seiler has published over 100 peer-reviewed publications and written over 100 popular science articles related to exercise physiology and the training process. He has also given scientific lectures across Europe, the United States, China, South Africa, and Australia. He is also a founding editorial board member of the International Journal of Sport Physiology and Performance.

Make the Boat Go Faster: 150 Years of Rowing Research

Dr. Stephen Seiler surveys 150 years of competitive rowing data to show that, from 1829, rowers have set linear speed improvements of about 2-3 percent per decade. But why?

Polarized Training: Managing the Distribution of Training Intensity

Dr. Seiler presents on the topic of training intensity when using polarized training.

How to Create Multi-Year Development Plans, with Dr. Stephen Seiler and Sondre Skarli

Episode 141

Certain physiological gains only happen after years of development. We discuss how to design training plans that look two or more years ahead.

Moving from Polarized Training to Personally Optimized Training

Dr. Stephen Seiler presents the reasons, methods, and benefits of moving from a polarized training template to a more personalized, optimized training method that is still based on polarized training.

An Introduction to Polarized Training

Dr. Stephen Seiler introduces polarized training during this in-studio podcast with FLO Cycling.

Strength and Speed Workouts for Runners

For distance runners unable to do high-intensity aerobic intervals, Dr. Stephen Seiler suggests adding strength and speed work.

How Moving Training Indoors Affects Our Workouts

Dr. Stephen Seiler surveyed over 1,000 endurance athletes of different levels to find out how the basic characteristics of the training process have changed during the coronavirus pandemic. Here are the results.

Dr. Seiler: Short Interval Stacks, Part 3

In this final video of his "short stack", three-part series, Dr. Stephen Seiler discusses some research studies that compare short interval and long interval training and how they impact endurance capacity in already well-trained athletes.

Dr. Seiler: Short Interval Stacks, Part 2

Dr. Stephen Seiler walks through some real-life short interval workout data to reveal some rules of thumb for how you can integrate these into your own training.

Dr. Seiler: Short Interval Stacks, Part 1

Interval training sessions with repeats of 30:30s, 40:20s, and 30:15s have become very popular. How does the (endurance-trained) body respond to this type of high-intensity interval prescription?
