Why I Named my Business Critical Oxygen - The Origin Story | #35 ft. Dr. Robert Jacobs

This episode of the Critical Oxygen podcast explores the concepts of critical power and critical oxygenation. Dr. Robert Jacobs and I discuss the definition and measurement of critical power, including the limitations and variability of the measurement. We also introduce the concept of critical oxygenation and its relationship to critical power. The episode concludes with a discussion on the use of NIRS for measuring critical oxygen! TAKEAWAYS 1) Critical power is a measurement that represents the maximal sustainable pace an individual can maintain for extended periods of time. 2) Critical oxygenation is a related concept that represents the maximal metabolic steady state of oxygen utilization in the muscles. 3) The measurement of critical power and critical oxygenation can be influenced by various factors, including individual variability and measurement techniques. 4) NIRS devices can be used to measure critical oxygenation, but proper placement and troubleshooting are important for accurate results. 5) Muscular limitation shift towards central limitations after training. 6) Embrace new technology with healthy skepticism.Enjoying these podcasts?
