Fast Physiology with Dr. Phil: W'(prime), Functional Reserve Capacity, and Vlamax

Training Babble: Off-Road Insights for Mountain Bike and Gravel Cycling

In this episode of the Training Babble podcast, host Dave Shell is joined by exercise physiologist Dr. Phil Batterson for an in-depth discussion about key physiological concepts and their relevance to endurance training. Dave and Phil dive into topics including:

• W'(prime), also known as functional reserve capacity
• VLamax, the maximal rate of lactate production in the blood
• The relationship and differences between anaerobic work capacity and glycolytic capacity
• How these metrics relate to performance in various sports

Dr. Phil shares his expert perspective on the practical application of these physiological measures. The pair explore when and why metrics like VLAmax may or may not make a meaningful difference in training and race outcomes for endurance athletes.

Through their discussion, Dave and Phil tackle common questions such as: Should you aim to increase your VLAmax? Will a lower VLAmax automatically boost VO2max? What adaptations actually move the needle on performance?

Tune in for an accessible yet scientific conversation that will expand your understanding of the physiology behind training adaptations. Whether you're a triathlete, cyclist, runner, or coach, you'll come away with new insights to inform your training approach.
