Can we use HRV to Optimize Sleep, Recovery, and Training? #63 - Fast Phys 13 ft. Dave Schell

In this episode of Fast Physiology on the Critical Oxygen podcast, Dave Schell and I discuss the use of heart rate variability (HRV) for training. We explore the benefits and limitations of HRV as a training tool, emphasizing the need for context and integration with other training data. The conversation highlights the importance of paying attention to sleep and recovery habits, and the potential benefits of wearables in bringing awareness to these factors. TAKEAWAYS - HRV is a valuable tool for exploring how different factors affect recovery and training adaptations. - The use of wearables can bring attention to sleep and recovery habits, but should be integrated with other training data and not relied upon as the sole metric for decision-making. - Paying attention to context and isolating variables is crucial for accurately interpreting training data and making informed decisions. - The limitations of tools like HRV and the need for a holistic approach to training and performance monitoring are important considerations for athletes and coaches.
