Fast Talk podcast, ep. 54: Applying the polarized training model, with Dr. Seiler
The VeloNews Fast Talk podcast is your source for the best training advice and most compelling insight on what it takes to become a better cyclist. Listen in as VeloNews managing editor Chris Case and our resident physiologist and coach, Trevor Connor, discuss a range of topics, including sport science, training, physiology, technology, nutrition, and more.
IN EPISODE 51, which we published several weeks ago, we had the chance to speak with Jay-Z — or at least the Jay-Z of the exercise physiology world, Dr. Stephen Seiler. We took a deep dive into the polarized model of endurance training … or so we thought.
We probably received more questions about that episode than any other episode to date. Many of you wanted to know more about how to execute a polarized training plan. We thought about doing a special episode to answer all of your questions, but instead, we begged and pleaded with Dr. Seiler to share a lovely late-summer Norwegian afternoon with us. He generously obliged.
During our conversation, we discussed:
- Why cycling is an aerobic sport
- What is meant by the two thresholds — LT1 and LT2 — and how to determine yours, both in terms of power and heart rate. Dr. Seiler provides a test protocol to determine LT2, which may sound very similar to Neal Henderson’s test that was described in episode 33, “Is FTP dead?”
- Why it’s important not to over-estimate LT1 or LT2, and how to use them to determine your zones in a three-zone model.
- The specifics of zone 1 training: how long, how much, how easy? We take a deep dive into what zone 1 training is all about, why it’s important to keep those rides easy, and the value of long rides.
- Finally, we discuss the 80-20 principle of the polarized model and how to put it into practice to map out your week.
One thing to note: A lot of listeners asked for example numbers to help them better understand the polarized approach. We chose to use Trevor’s numbers for a few reasons. First, he’s a big believer in polarized training and has much success with it. Second, he’s a very aerobically developed cyclist. Third, like many of you, he’s a master’s rider with limited time to train. Finally, the data was readily available allowing us to give example numbers throughout.
Our featured guest is, of course, Dr. Stephen Seiler, a professor of sports science in Norway, where he has lived for over 20 years. He sits on the executive board of the well-respected European University College for Sports Science. It was his groundbreaking research that helped define the polarized model.
We also hear from Dr. John Hawley, another prominent name in the exercise science world from Australia. His research over the past few decades has helped to define endurance sports training and nutrition. He talks with us about one of the important, but lesser-known, gains of long rides.
Finally, we speak with Kiel Reijnen of the Trek-Segafredo WorldTour team. Kiel spoke with us about why even pros sometimes prefer two-a-day rides.
So, are you ready to know what going easy really means? Ready to understand what some of the great endurance athletes are doing to train? Are you ready to get polarized? Well, let’s make you fast!
