Week 25: All About HRV

Hi there 👋

Last week, I had a great conversation with Dan and Owain for their podcast (The Physiology of Endurance Running, which I’d recommend checking out regardless of this interview!).

We discussed pretty much everything from the physiological basis of HRV to applied protocols and limitations of current technologies, including pros and cons of using wearables, issues with stress estimates derived from continuous data, HRV during exercise, and more.

You can find the episode here:

I hope you will find it interesting. Thank you for listening!

Last weekend, we organized a trail race here in Brisighella, something I had been working on for the past year, together with Alessandra Saviotti and a few others who got us involved after we started spending part of the year back home.

It’s been wonderful to see so many old and new friends come together for a lovely morning on our trails (and some good food afterwards!).

Volunteering, directing, crewing my athletes, cheering, running around. What a day. My heart is full, and I cannot wait to start working on the next edition.

Thank you to everyone who joined us and helped make it happen.

p.p.s. If you haven’t been to Brisighella yet, join us in June 2027.

Please apply here should you be interested in working with me.

You can also learn more about my coaching, here.

Thank you!

Our book is out and available for purchase from Human Kinetics’ website, here (or on Amazon).

HRV4Training Pro is the ultimate platform to help you analyze and interpret your physiological data, for individuals and teams.

When using Pro, the app will also automatically recognize your account and add the Normal Range to the Baseline view, together with detected trends and additional annotations, which can help contextualizing longer-term changes.

You will also be able to pick rMSSD as the parameter to see on the homepage of the app.

Thank you again for your support and for allowing us to remain independent.

See you next week!
