Coaches Trevor Connor and Ryan Kohler analyze the Power Duration Curve in order to illustrate how you can train fatiguability.
In this video, Dr. Seiler thinks out loud—with math—to explore how critical power and variable intensity races might connect in practice.
Coach Ryan Kohler demonstrates ways to train maximal force production, or torque, on the bike.
Coach Ryan Kohler reviews season-to-season changes in heart rate/power distributions to illustrate improvements across the different energy systems.
The execution of long slow distance rides might sound simple, but many people struggle to get it right. Can you be too steady on your LSD rides?
Cardiovascular drift is an instability in heart rate and stroke volume over time. We show you how to determine it.
Dr. Stephen Cheung discusses a study comparing steady-state versus fast-start intervals, then uses Xert software to model how a fast-start interval can be much more intense.
The variable terrain of most MTB trails makes it difficult to keep power steady. So, is it possible to get solid base rides on the mountain bike?
