This is very interesting. How much yoga do we need to do to get an effect? Well, according to a new study by the Centre of Yoga Therapy, Education and Research and the Mahatma Gandhi Medical College & Research Institute in India, they have revealed that a single session of yoga can significantly reduce heart rate and blood pressure. This is one of many studies that CYTER are undertaking.
According to the conclusion of the study, a single yoga session can reduce the heart rate, blood pressure and derived cardiovascular indices. The magnitude of the reduction depends on the pre-existing medical conditions, as well as the protocol of yoga therapy that is adopted.
The changes in the cardiovascular system could be attributed to an enhanced harmony in cardiac autonomic functions, resulting from the coordinated breath-body work, as well as the relaxation of mind and body, Deputy Director (Yoga) of CYTER Ananda Balayogi Bhavanani told The Hindu Newspaper .
For the study, data of 1896 patients – 1229 women, 633 men and 34 transgender – from the ages of 24 to 48 was analysed. These people attended yoga sessions between November 2010 and September 2012 and heart rate, systolic and diastolic pressure were measured after only one 60 minute yoga session. Pulse pressure, mean pressure, rate pressure product and double produce were derived from the data.
In patients with hypertension, there was a significant reduction in cardiovascular parameters following the session. For people with skin problems and muscular-skeletal problems, the reduction was less significant. However the study indicated that in patients with no health conditions as well as those with psychiatric and respiratory conditions, there was a moderate change in the cardiovascular markers.
According to Dr. Bhavanani, although there have been several studies on the physiological, psychological and biochemical changes following yoga practice, only very few have focussed on the effect of a single session.
