I've enjoyed this chat with Adam, talking about heart rate variability (HRV) outside of sports setting. We discussed the basics, physiology, technology, stressors, sickness, deep breathing and more. It might be a useful one if you are new to the topic. Thank you for listening  This episode of Longevity by Design is an in-depth discussion on heart rate variability (HRV) and the stress response. We discuss the definition of HRV, how stress impacts the autonomic nervous system, and the many factors that influence HRV. thank you for having me and enjoy.  It took a while to learn what works for me in terms of training, rest, and diet, and to better manage stress I certainly did not expect a 5-year break from racing PRs (nor I expected at this point to break any PR anymore) yet, progress isn’t linear in my latest blog I tried to cover the past 6 months and the changes I implemented: • my training plan and periodization • the tools I built to track progress • how I managed the plan • training intensity distribution • diet and performance thank you for reading  More and more wearables have started capturing Heart Rate Variability (HRV) data overnight and combining it with other parameters (e.g. heart rate, sleep data, physical activity) to provide readiness or recovery advice to the user. Despite some inconsistencies over the past years, as of the end of 2022, Oura, Whoop, and Garmin all work in a very similar way when it comes to HRV measurement. However, the way the data is used in all of these tools when building readiness or recovery scores or when providing advice to the user is often problematic and inconsistent. Naive interpretations (higher is better), lack of a normal range (what’s a meaningful change?), and confounding your physiological response with your behavior, are common issues that limit the utility of data collected with wearables. In my latest blog, I cover data analysis and interpretation to provide you with some useful tips and tools that should allow you to make the most of the collected data and ignore inaccurate interpretations provided by most tools out there. Thank you for reading.  |
