How Does your Physiology Predict your Endurance Performance? | #5 ft. Dr. Robert Jacobs
Welcome to the Critical Oxygen Podcast! In this episode Dr. Robert Jacobs and I talk about the three main predictors of endurance performance. Maximal oxygen uptake (VO2max), metabolic thresholds (i.e. lactate, ventilatory (oxygen and carbon dioxide), etc.), and economy/efficiency.
Enjoy!

0:00 – Introduction
0:20 – What we know from research and biological variability.
3:11 – What can we take away from a bad study?
5:10 – The challenge with human studies
5:46 – Be open to changing your ideas based on the research!
6:39 – The optimal training plan example
8:23 – Our plan to share research

21:55 – How can we use multiple different devices to predict our thresholds?
22:50 – What do our different thresholds tell us?
25:07 – Are critical power and vo2max the same thing in some situations?
27:08 – Why altitude reduces your VO2max and performance?
