The Physiology of Durability and Fatigue Resistance | #82 ft. Gabriele Gallo, Ph.D.

1 hour 20 minutes

In this episode of the Critical Oxygen podcast, Gabriele Gallo, Ph.D. and I explore the concept of durability and fatigue resistance in endurance sports.

We discuss the definitions of durability and recovery, the importance of measuring these factors, and the role of carbohydrate availability in maintaining performance.

The conversation also explores the physiological mechanisms behind fatigue and how athletes can optimize their training and nutrition to enhance durability. The discussion covers various aspects of training, including the significance of high volume, low intensity workouts for improving durability, and the ongoing debate regarding carbohydrate consumption for performance.

TAKEAWAYS

- Durability is defined as the ability to maintain performance during prolonged exercise.

- Recovery ability refers to maintaining performance over consecutive days of training or competition.

- Standardizing testing conditions is crucial for accurate durability assessments.

- Maintaining glycogen levels is vital to prevent muscle fatigue during prolonged exercise.
