Running Physiology part 3 – lactate threshold

Part 3 – Lactate Threshold  In parts one and two of this series, I dissected the theory of VO2max and explained the significant challenges that have been mounted against it.  In order to answer these challenges, physiologists have advanced several … Continue reading

Muscles limit endurance performance

Based on the available research I believe that muscles exert the strongest influence on endurance performance.  In this article I will attempt to prove that muscles, not oxygen, are ultimately responsible for your endurance performance.  This is a tall order … Continue reading

The Surprising Aerobic Benefit of Sprinting

If you’ve been involved in running for any length of time you have surely been exposed to the concepts of aerobic and anaerobic training.  These two terms are firmly entrenched in the running community, having been in use for more … Continue reading

Central Governor Model

The most enduring model of endurance physiology is the Cardiovascular/Anaerobic model.  Initially suggested by British physiologists A.V. Hill and associates in the mid-1920s, this model has been promoted by scientists, coaches, and athletes world-wide for nearly 80 years.  This model … Continue reading
