Long term effects of deep breathing on Heart Rate Variability

In this post, I look at the long-term effects of deep breathing on heart rate variability (HRV) as measured during deep breathing practice
​
While there is plenty of data and published literature on the acute effect of deep breathing on HRV (basically the difference between resting conditions and practice), we know much less about long-term effects. Looking at this data might help us better understand the relationship between deep breathing and long-term physiological changes (if any!)
