Abstract

 

With increased awareness and interest in health and natural remedies, yogic techniques including pranayama are gaining importance and becoming increasingly acceptable to the scientific community.  There is evidence that pranayama training produces deep psychosomatic relaxation and improvement of cardio-respiratory efficiency. Present study was conducted in the Department of Physiology, Government Medical College, Aurangabad.  Eighty (80) healthy volunteers in the age group of 35-55 years were taken in the study.  Group-I subjects did pranayama under supervision of a qualified yoga teacher and practiced the same for 1 hour daily for a total duration of 8 days. Group-II subjects did same pranayama exercise under supervision of a qualified yoga teacher and practiced the same for 1 hour daily for a total duration of one month. In group-II, pranayama training produced a significant decrease in systolic blood pressure, the difference being statistically significant (p<0.05).  On the other hand there was no significant change in systolic blood pressure in group-I.  Pulse rate showed significant decrease in the group-II (p<0.01) whereas in the group-I there is no significant change in pulse rate.  Also there is significant decrease in body weight in group-II (p<0.001).  On the other hand there was no significant change in the body wt. in group-I.  There was no significant change in diastolic blood pressure and respiratory rate in both groups. In conclusion, the present study shows that one month of pranayama training produces a significant decrease in pulse rate and systolic blood pressure.  The decrease in systolic blood pressure and pulse rate may have been brought about by increased parasympathetic and decreased sympathetic activity.  Decrease in body weight may be due to burning of fat during pranayama.
