HRV for Runners: What Your Morning Number Actually Means — Marco Altini

Your HRV dropped after a hard session. Most runners take that as proof they trained hard. Marco Altini says it's proof of the opposite.Marco is the founder of HRV4Training, an advisor at Oura, and an endurance coach. He came to physiology the long way round — from computer science and early wearable prototypes, back to university to study sports science, because he wanted to understand the bodies he was measuring.In this conversation we cover what HRV actually measures, why "higher is better" is wrong, how to build your normal range, morning vs night measurement, what to change when your baseline drops, why a falling HRV in taper week is the good news, and why the data should make you need the data less.Find Marco on Substack, where he writes about HRV, training and coaching.Want structured, evidence-based coaching?
