The Heart Rate VariabilityT test is a simple, non-invasive, fully automated computer-based system designed for quantitative assessment of the Autonomic Nervous System (ANS)To put it simply it measures your ability to heal and adapt to stressors. It compares your current level of health to the excellent level maintained by an olympic athlete. It is a great way to measure your success in health--you can do the test in the beginnning of your health improvement program and then again in several weeks to see how you are progressing
A study was designed to quantify and compare the instantaneous changes of heart rate variability (HRV) during Shambhavi Mahamudra, a practice of Isha yoga.
It includes major stages viz. Sukha pranayam, 'AUM' chanting, rapid breathing, and relaxed sitting.
The standard lead II electrocardiogram (ECG) signals were acquired from eight healthy, yoga practitioners while performing various stages of Shambhavi Mahamudra. The short-term HRV were extracted from ECG, and analyzed using time, frequency-domain and Poincaré plot methods.
The results showed a combination of increased sympathetic tone and withdrawal of vagal tone during Sukha pranayam, an increased sympathetic tone during `AUM' chanting, and withdrawal of vagal tone during rapid breathing.\
The HRV descriptors were not significantly different during relaxed sitting
Hi,
ReplyDeleteI'm glad to come across your blog. I was looking for more details on the posting you had made. Can you please point me to any publication/write up of the study that you had posted here.
Btw, I'm Isha meditator and I'm trying to inspire others to do the same, I'm always on the look out for studies like this.
thankyou
