In this episode of the Critical Oxygen podcast, Dave Schell and I discuss the use of Near Infrared Spectroscopy (NIRS) technology, specifically the Moxy Monitor, to enhance endurance training. We discuss the importance of proper placement of the device, how to interpret SMO2 readings, and the practical applications of NIRS in optimizing warmups and training readiness. The conversation emphasizes the need for athletes to understand their physiological responses to training and how to use this data to inform their workouts effectively. TAKEAWAYS - Proper placement of the Moxy Monitor is crucial for accurate readings. - SMO2 indicates how muscles cope with exercise intensity. - Warmups should be tailored to individual needs for optimal performance.
