A Deep Dive Into HRV: The Myths & Truths of Heart Rate Variability Testing

Australian HRV researcher Dr. James Heathers (pictured above) is one interesting dude.

On a professional level, he is a Ph.D and an Endeavour Research Fellow in Electrocardiology at Poznan University of Medical Science, where his research revolves around measurement issues in heart rate and heart rate variability.

On another level, he has an extremely interesting and thought-provoking blog, where he writes about health, science, medicine and bioethics, and has articles on topics such as medical sensors embedded in tattoos, how drinking affects sleep quality, how peptides are used for doping by professional athletes, and much more.

In our discussion in this podcast, James and I take a deep dive into HRV, and our topics include: -How James went from being an experimental psychologist to instead being immersed in HRV research... -Very interesting ways to use HRV that tend to fly under the radar, including computer gaming and cognitive performance enhancement... -Whether HRV can really measure the things that the self-quantification industry often claims it can measure (e.g. sympathetic outflow, or blood lactate, or ‘readiness’)... -When a high HRV may not be a good thing... -Which supplements and medication affect HRV... -The main areas of research in HRV now that James is most excited about, including something called HRR and breathing ladders... -And much more!

Warning: if you know nothing at all about HRV, you will probably need a good intro to HRV prior to listening in, because this particular podcast is a bit more advanced, and skips over the basics of HRV.

The good news is that there is over three years of HRV articles and podcasts on BenGreenfieldFitness.com, and here are the most popular and useful: –The Do-It-Yourself Guide To Using Heart Rate Variability Testing to Track Your Stress and Nervous System Health (podcast) –Everything You Need To Know About Heart Rate Variability Testing (podcast) –What Is The Best Way To Track Your Heart Rate Variability (HRV)? (podcast) –25 Ways To Know With Laser-Like Accuracy If Your Body Is Truly Recovered And Ready To Train (article) –Do Professional Sports Teams Have It All Wrong When It Comes To Optimizing Performance & Recovery? (article)

Other resources we discuss during this episode: -Article on metabolic breathing ladders -How HRV correlates to blood lactic acid -The effect of fish oil on HRV -Bitalino (a second-generation research grade ECG machine that you can buy for a few hundred dollars) -The SimBand (Samsung has released a research platform for developers called Simband, who can now use the platform to build their own software applications without having to build their own hardware) -Video magnification of HR using a webcam (a lab at MIT developed a method of pulling your heart rate straight out of a webcam picture) -GreenfieldFitnessSystems NatureBeat app for HRV

Listener Pat asks: After severing my patella eight years ago, and after bone carpentry (term used by my surgeon) I literally sat for nearly a year and during that time my quads wouldn't respond to any brain commands to even flex! When I was up and around again, I noticed cellulite had developed between my knees and hips. Once regular workouts began, and now this many years later, the cellulite pretty much still remains on top of the muscles. I am looking fwd. to trying at least one of these products to see if the cellulite diminishes. I am curious what this topical cream does to the skin texture with repeated applications?
