Introduction : Yoga, a mind body technique involves relaxation, meditation and a set of physical exercises performed in sync with breathing. The word “Pranayama” is made up of two words, Prana and Ayama. Prana stands for the capacity to keep body alive by air, i.e breathe and Ayama means expansion, stretching or extention and control of breath. Yoga helps to improve the cardiovascular efficiency and homeostatic control of the body. Hence we decided to study the effect of Pranayama on blood pressure in healthy subjects.

Materials and Methods: It was a longitudinal study. 30 healthy subjects of age group 18-30 years were recruited for this study. The study was conducted in the Department of Physiology, Santosh Medical College and Hospitals, Ghaziabad. Blood pressure was measured by using a sphygmomanometer using palpatory and auscultatory method. Six minute walk test was conducted as per American Thoracic Society (ATS) guideline. 40 minutes yoga training 2 times per week. The training consisted of warm up for 5 min, Pranayama for 25 min and Meditation for 10 min. Statistical Analysis: Data was entered in to MS Excel and expressed as Mean and SD. Differences between groups before and after intervention was assessed by t-test using SPSS 23.0 software. Results: It was observed that there was a  statistically significant decrease in systolic blood pressure after 4 weeks of Pranayama training which decreased from  118.20 + 6.376 mmHg to 114.07 + 5.693  mmHg after Pranayama (p < 0.001). There was a statistically significant decrease in diastolic blood pressure after 4 weeks of Pranayama training which decreased from 76.80 + 5.268 mmHg as compared to 72.73 + 4.968  mmHg after 4 weeks of Pranayama training (p < 0.001). There was a statistically significant increase in walk distance on six minute walk test after 4 weeks of Pranayama training from 526.67 + 25.795 m  to 682.60 + 25.425  m after 4 weeks of Pranayama training (p < 0.001). Discussion: The present study revealed that there was a  significant decline in both systolic and diastolic blood pressure after Pranayama. There was a significant increase in six-min walked distance after Pranayama.
