V2 Max is a more reliable predictor of all-cause mortality and more modifiable than heart rate variability.

“as much as people are worrying about their HRV and people really do worry about it you should worry more about your V2 Max because you have more control over it and it's a better predictor of all cause mortality”

Consistent resonance breathing training can produce long-term adaptations that increase baseline heart rate variability.

“Now across time, this is that's more of like state change of the nervous system. trait change or the longer term adaptations. They start to really happen when we're doing it consistently week over week, day over well day over day, week over week. And then we see that anywhere from around 6 to 8 week”

Heart Rate Variability is a measurable metric of autonomic flexibility that indicates an individual's resilience and adaptability to stress.

“what we'll talk about today is HRV in terms of RSA resonance sinus rythmia and it's so much easier to understand and grasp as a user because you can look at with all sorts of different variables that are out now the peak to trough so when you inhale your heart rate goes up and when you exhale it goe”

Heart rate variability is a sensitive and powerful metric for understanding autonomic nervous system balance and general physical readiness.

“and therefore, a higher heart rate variability in comparison to a baseline of a heart rate variability is typically indicating that your body is in a state of rest or it's more balanced. Uh when it's out of balance, that's a sign that your body might be run down, might be um under stress.”
