Abstract: Pranayamas are breathing techniques that exert profound physiological effects on pulmonary, cardiovascular and mental functions. It deals with the knowledge, control and enrichment of this vital force. The study was conducted to study the effect of 12 weeks of pranayama training on basal physiological parameters in young subjectson 60 healthy volunteers. After obtaining informed, written consent, subjects were randomized into pranayama (n= 30) and control groups (n= 30). Supervised training was given to the pranayama group by a certified yoga instructor and they practiced Pranava, Nadishodana and Savitri pranayamas. Basal physiological parameters such as heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and respiratory rate (RR) were recorded at the beginning and after 12 weeks of study period. Pranayama training resulted in marginal improvement (P > 0.05) in the measured cardiovascular parameters while RR decreased significantly from 17.66 ± 1.2 to 16.86 ± 0.92 (P <0.01). In control group there was no significant change (P > 0.05) in the tested cardiovascular parameters such as HR, SBP and DBP. 12 weeks of pranayama training showed improvement in the tested basal physiological parameters with significant decrease in RR. The RR depends on mental-ernotional activity and this decrease in RR may be attributed to a calm and stable mind-ernotion complex in our subjects.
