After many years of study, the health impact of coffee remains mixed. But heart rate variability (HRV) may have a relationship with long-term coffee consumption. A new study of over 15,000 subjects looked at the relationship between coffee consumption and HRV readings.
What is Coefficient of Variation (CV)? How is CV connected to the HRV score and ln(rMSSD)? What are “good” and “bad” CV trends? How do I use it to interpret and tailor training?
Check out this blog post by guest writer, Andrew Flatt, to answer these questions and more.
Dan Quintana is a Research Fellow at the University of Oslo and received his PhD in Psychology from the University of Sydney in 2013. His research focuses on the role of heart rate variability, the autonomic nervous system and hormones on mental health. In this episode, we’re going to pick Dan’s brain on the relationship between mental and physical health, autonomic dysregulation, how HRV reflects mental health condition, antidepressants and other interventions.
Overfat & Underfat: New Terms & Definitions Long Overdue with Dr. Phil Maffetone & Professor Paul Laursen
First coverage with Dr. Phil Maffetone and Professor Paul Laursen on their newly published and controversial scientific paper titled: “Overfat and Underfat: New Terms and Definitions Long Overdue.” We discuss the pandemic of people who are “overfat” — defined as having sufficient excess body fat to impair health and how this classification differs from “overweight”. If we’re to truly address the problem, we need to start using the right terminology and not hiding behind propriety (in certain situations). Doctors, researchers and individuals all need to arm themselves to take control of what some are now calling the “world health crisis”.
Andrew Flatt goes deep into the research and application of HRV monitoring for athletes and sports teams. Andrew works extensively with elite level athletes and is one of the emerging names in athlete monitoring research.
Baroreceptors, which are the body’s natural blood pressure sensors located in the aortic arch and internal carotid arteries, contribute to Heart Rate Variability. When you inhale, heart rate increases.
Our HRV score is calculated from the RMSSD and represents the strength of your Autonomic Nervous System (specifically the Parasympathetic branch) at a given time. The other numbers provided are for reference for those interested in in more detailed analysis of their HRV data.
