That Triathlon Show
Introduction
Dr. James Prag shares cutting-edge insights from his PhD studies on durability research, highlighting rapid developments in the field. The episode also acknowledges sponsors Precision Fuel and Hydration, and Zen8 for their support.
James Spragg, PhD, is a cycling coach at the Tudor Pro Cycling Team and performance consultant. His PhD research focused on durability, which is the main topic of today's interview.
IN THIS EPISODE YOU'LL LEARN ABOUT:
-The concept of durability
-The relationship between training characteristics and durability in cycling
-The relationship between physiological measures and durability in cycling
-The type of intensity, not just the amount of work done, impacts the downward shift in power profile
-Critical Power (or Critical Speed) is a more comprehensive marker of performance physiology than VO2max
-Listener questions: how to know when to work on what part of the power-duration curve and more
