In this episode of the Critical Oxygen podcast, Dr. Robert Jacobs and I discuss exercise economy and efficiency. We explain the importance of zone two training for improving volume and intensity, and it's role in increasing economy. We define exercise economy as the amount of oxygen per wattage or unit speed and discuss its measurement challenges. We also explore the factors that affect economy and efficiency, such as aging, experience, and biological changes. Additionally, we highlight the benefits of lifting heavy weights and provide practical examples for improving efficiency through strength training.
1) Increasing volume by completing zone 2 training can help to improve running economy.
2) Heavy strength, powerful lifting, and plyometrics can help to improve economy and efficiency.
